Mybatis、SpringMVC练习
CRM系统
- 回顾
Springmvc 高级参数绑定 数组 List
<input type name=ids /> 多个
方法 (Integer[] ids) QueryVo (里面Integer[] ids)
方法（QueryVo 里面List<Items> itemList
<input type name=itemList[${s.index}].name />
- 2. REquestMapping 处理器映射器（找此标签 路径 ）
Value = {多个路径,}
Value = {/item/sfdsf.action} 类头上
Method=RequestMethod.POST或GET
3、 Controller方法返回值
三个
ModelAndView 建议不使用 不解偶
String 返回视图的路径 （形参 绑定Model ） 重定向redirect:另一个方法的映射路径 forward:内部转发
Void 异步请求使用
- 异常处理器
预期、运行时
自定义异常处理类 实现HandlerEexceptionResolver
由Spring实现化 自定义的处理类
未知异常
CustomEexception 继承Eexception
4、 上传图片
1）Form 上传图片了 action上传路径
2）input type=file name=picturePic
3)接收此图片 形参上绑定 MultipartFile picturePic 接口
4）配置此接口的实现类 Springmvc.xml配置CommonsMultipartFileResolver id=multipartFileResolver
5、JSON数据交互
应用场景：前端是各种 html Freemarker JSP一个Servlet 是Java代码 jstl C
浏览器 Ajax 发送JSON字符串 报文
6、拦截器
拦截器 应用 （练习）

创建crm数据库，执行sql
效果如下图：
3. 工程搭建
使用的Bootstrap前端框架,官方网站
http://www.bootcss.com/
工程使用Springmvc、spring、mybatis框架整合完成。
3.1. 需要的jar包
- spring（包括springmvc）
- mybatis
- mybatis-spring整合包
- 数据库驱动
- 第三方连接池。
- Json依赖包Jackson
jar包位置如下图：
3.2. 整合思路
Dao层：
1、SqlMapConfig.xml，空文件即可，但是需要文件头。
2、applicationContext-dao.xml
a) 数据库连接Druid
b) SqlSessionFactory对象，需要spring和mybatis整合包下的。
c) 配置mapper文件扫描器。Mapper动态代理开发 增强版
Service层：
1、applicationContext-service.xml包扫描器，扫描@service注解的类。
2、applicationContext-trans.xml配置事务。
Controller层：
1、Springmvc.xml
a) 包扫描器，扫描@Controller注解的类。
b) 配置注解驱动
c) 配置视图解析器
Web.xml文件：
1、配置spring监听器
2、配置前端控制器。
3.3. 创建工程
创建动态web工程，步骤如下图：
创建boot-crm，如下图
3.4. 加入jar包
加入资料中的jar包
3.5. 加入配置文件
创建config资源文件夹，在里面创建mybatis和spring文件夹
3.5.1. SqlMapConfig.xml
空文件即可
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 3 "http://mybatis.org/dtd/mybatis-3-config.dtd"> 4 <configuration> 5 6 7 8 </configuration>
3.5.2. applicationContext-dao.xml
需要配置：
加载properties文件，数据源，SqlSessionFactory，Mapper扫描

4.2. 页面显示问题
访问页面，发现不能正常显示
打开开发者工具，选择Network，
发现css、js等资源文件无法加载
原因：web.xml配置时，是设置所有的请求都进入SpringMVC。但是SpringMVC 无法处理css、js等静态资源，所以无法正常显示
解决方案：
1. 在springmvc.xml中配置
1 <!-- 解决静态资源无法被springMVC处理的问题 --> 2 <mvc:default-servlet-handler />
2. 修改web.xml，让所有以action结尾的请求都进入SpringMVC
1 <servlet-mapping> 2 <servlet-name>boot-crm</servlet-name> 3 <!-- 所有的请求都进入springMVC --> 4 <url-pattern>*.action</url-pattern> 5 </servlet-mapping>
解决后的效果如下图，可以正常显示页面样式：
我们使用第二种方式解决，因为此项目中的页面的请求都是以action结尾的，所以使用第二种方式，在web.xml里面进行相应的配置
1 <servlet-mapping> 2 <servlet-name>boot-crm</servlet-name> 3 <!-- 所有以action结尾的请求都进入springMVC --> 4 <url-pattern>*.action</url-pattern> 5 </servlet-mapping>
5. 实现查询条件初始化
5.1. 需求分析
页面效果如上图，在查询客户的时候，可以选择客户来源,所属行业,客户级别信息,页面加载时需要初始化查询条件下拉列表。
前端jsp逻辑
1 <form class="form-inline" action="${pageContext.request.contextPath }/customer/list.action" method="get">
2 <div class="form-group">
3 <label for="customerName">客户名称</label>
4 <input type="text" class="form-control" id="customerName" value="${custName }" name="custName">
5 </div>
6 <div class="form-group">
7 <label for="customerFrom">客户来源</label>
8 <select class="form-control" id="customerFrom" placeholder="客户来源" name="custSource">
9 <option value="">--请选择--</option>
10 <c:forEach items="${fromType}" var="item">
11 <option value="${item.dict_id}"<c:if test="${item.dict_id == custSource}"> selected</c:if>>${item.dict_item_name }</option>
12 </c:forEach>
13 </select>
14 </div>
15 <div class="form-group">
16 <label for="custIndustry">所属行业</label>
17 <select class="form-control" id="custIndustry" name="custIndustry">
18 <option value="">--请选择--</option>
19 <c:forEach items="${industryType}" var="item">
20 <option value="${item.dict_id}"<c:if test="${item.dict_id == custIndustry}"> selected</c:if>>${item.dict_item_name }</option>
21 </c:forEach>
22 </select>
23 </div>
24 <div class="form-group">
25 <label for="custLevel">客户级别</label>
26 <select class="form-control" id="custLevel" name="custLevel">
27 <option value="">--请选择--</option>
28 <c:forEach items="${levelType}" var="item">
29 <option value="${item.dict_id}"<c:if test="${item.dict_id == custLevel}"> selected</c:if>>${item.dict_item_name }</option>
30 </c:forEach>
31 </select>
32 </div>
33 <button type="submit" class="btn btn-primary">查询</button>
34 </form>
按照jsp的要求,把对应的数据查询出来,放到模型中。
数据存放在base_dict表，可以使用dict_type_code类别代码进行查询
使用需要获取的数据如下图：
使用的sql:
SELECT * FROM base_dict WHERE dict_type_code = ‘001‘
5.2. 实现DAO开发
5.2.1. pojo
因为页面显示的名字是下划线方式，和数据库表列名一样，根据页面的样式，编写pojo
1 public class BaseDict {
2 private String dict_id;
3 private String dict_type_code;
4 private String dict_type_name;
5 private String dict_item_name;
6 private String dict_item_code;
7 private Integer dict_sort;
8 private String dict_enable;
9 private String dict_memo;
10 get/set方法自己实现
11 }
5.2.2. Mapper
编写BaseDictMapper
1 public interface BaseDictMapper {
2 /**
3 * 根据类别代码查询数据
4 *
5 * @param dictTypeCode
6 * @return
7 */
8 List<BaseDict> queryBaseDictByDictTypeCode(String dictTypeCode);
9
10 }
5.2.3. Mapper.xml
编写BaseDictMapper.xml
1 <?xml version="1.0" encoding="UTF-8" ?>
2 <!DOCTYPE mapper
3 PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
4 "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
5 <mapper namespace="cn.itcast.crm.mapper.BaseDictMapper">
6
7 <!-- 根据类别代码查询数据 -->
8 <select id="queryBaseDictByDictTypeCode" parameterType="String"
9 resultType="cn.itcast.crm.pojo.BaseDict">
10 SELECT * FROM base_dict WHERE dict_type_code =
11 #{dict_type_code}
12 </select>
13
14 </mapper>
5.3. 实现Service开发
5.3.1. BaseDictService 接口
1 public interface BaseDictService {
2
3 /**
4 * 根据类别代码查询
5 *
6 * @param dictTypeCode
7 * @return
8 */
9 List<BaseDict> queryBaseDictByDictTypeCode(String dictTypeCode);
10 }
5.3.2. BaseDictServiceImpl 实现类
1 @Service
2 public class BaseDictServiceImpl implements BaseDictService {
3
4 @Autowired
5 private BaseDictMapper baseDictMapper;
6
7 @Override
8 public List<BaseDict> queryBaseDictByDictTypeCode(String dictTypeCode) {
9
10 List<BaseDict> list = this.baseDictMapper.queryBaseDictByDictTypeCode(dictTypeCode);
11 return list;
12 }
13 }
5.4. 实现Controller开发
5.4.1. 修改之前编写的controller
1 @Controller
2 @RequestMapping("customer")
3 public class CustomerController {
4
5 @Autowired
6 private BaseDictService baseDictService;
7
8 /**
9 * 显示客户列表
10 *
11 * @return
12 */
13 @RequestMapping("list")
14 public String queryCustomerList(Model model) {
15 // 客户来源
16 List<BaseDict> fromType = this.baseDictService.queryBaseDictByDictTypeCode("002");
17 // 所属行业
18 List<BaseDict> industryType = this.baseDictService.queryBaseDictByDictTypeCode("001");
19 // 客户级别
20 List<BaseDict> levelType = this.baseDictService.queryBaseDictByDictTypeCode("006");
21
22 // 把前端页面需要显示的数据放到模型中
23 model.addAttribute("fromType", fromType);
24 model.addAttribute("industryType", industryType);
25 model.addAttribute("levelType", levelType);
26
27 return "customer";
28 }
29 }
5.4.2. 效果
实现效果如下图：
5.4.3. 硬编码问题
这里是根据dict_type_code类别代码查询数据，这里的查询条件是写死的，有硬编码问题。可以把类别代码提取到配置文件中，再使用@value注解进行加载。
5.4.3.1. 添加env.properties
添加env.properties配置文件
#客户来源 CUSTOMER_FROM_TYPE=002 #客户行业 CUSTOMER_INDUSTRY_TYPE=001 #客户级别 CUSTOMER_LEVEL_TYPE=006
5.4.3.2. 修改springmvc.xml配置文件
在springmvc.xml中加载env.properties
1 <!-- 加载controller需要的配置信息 --> 2 <context:property-placeholder location="classpath:env.properties" />
注意:Controller需要的配置文件信息必须添加到springmvc的配置文件中
5.4.3.3. 修改Controller方法
1 @Controller
2 @RequestMapping("customer")
3 public class CustomerController {
4
5 // 客户来源
6 @Value("${CUSTOMER_FROM_TYPE}")
7 private String CUSTOMER_FROM_TYPE;
8 // 客户行业
9 @Value("${CUSTOMER_INDUSTRY_TYPE}")
10 private String CUSTOMER_INDUSTRY_TYPE;
11 // 客户级别
12 @Value("${CUSTOMER_LEVEL_TYPE}")
13 private String CUSTOMER_LEVEL_TYPE;
14
15 @Autowired
16 private BaseDictService baseDictService;
17
18 /**
19 * 显示客户列表
20 *
21 * @return
22 */
23 @RequestMapping("list")
24 public String queryCustomerList(Model model) {
25 // 客户来源
26 List<BaseDict> fromType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_FROM_TYPE);
27 // 所属行业
28 List<BaseDict> industryType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_INDUSTRY_TYPE);
29 // 客户级别
30 List<BaseDict> levelType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_LEVEL_TYPE);
31
32 // 把前端页面需要显示的数据放到模型中
33 model.addAttribute("fromType", fromType);
34 model.addAttribute("industryType", industryType);
35 model.addAttribute("levelType", levelType);
36
37 return "customer";
38 }

6. 客户列表展示
6.1. 需求
展示客户列表，并且可以根据查询条件过滤查询结果，并且实现分页。
效果如下图：
页面代码：
1 <div class="panel-heading">客户信息列表</div>
2 <!-- /.panel-heading -->
3 <table class="table table-bordered table-striped">
4 <thead>
5 <tr>
6 <th>ID</th>
7 <th>客户名称</th>
8 <th>客户来源</th>
9 <th>客户所属行业</th>
10 <th>客户级别</th>
11 <th>固定电话</th>
12 <th>手机</th>
13 <th>操作</th>
14 </tr>
15 </thead>
16 <tbody>
17 <c:forEach items="${page.rows}" var="row">
18 <tr>
19 <td>${row.cust_id}</td>
20 <td>${row.cust_name}</td>
21 <td>${row.cust_source}</td>
22 <td>${row.cust_industry}</td>
23 <td>${row.cust_level}</td>
24 <td>${row.cust_phone}</td>
25 <td>${row.cust_mobile}</td>
26 <td>
27 <a href="#" class="btn btn-primary btn-xs" data-toggle="modal" data-target="#customerEditDialog" onclick="editCustomer(${row.cust_id})">修改</a>
28 <a href="#" class="btn btn-danger btn-xs" onclick="deleteCustomer(${row.cust_id})">删除</a>
29 </td>
30 </tr>
31 </c:forEach>
32 </tbody>
33 </table>
分析我们需要根据四个条件进行查询，返回数据是分页对象Page
Sql语句:
1 SELECT 2 a.cust_id, 3 a.cust_name, 4 a.cust_user_id, 5 a.cust_create_id, 6 b.dict_item_name cust_source, 7 c.dict_item_name cust_industry, 8 d.dict_item_name cust_level, 9 a.cust_linkman, 10 a.cust_phone, 11 a.cust_mobile, 12 a.cust_zipcode, 13 a.cust_address, 14 a.cust_createtime 15 FROM 16 customer a 17 LEFT JOIN base_dict b ON a.cust_source = b.dict_id 18 LEFT JOIN base_dict c ON a.cust_industry = c.dict_id 19 LEFT JOIN base_dict d ON a.cust_level = d.dict_id 20 WHERE 21 a.cust_name LIKE ‘%马%‘ 22 AND a.cust_source = ‘6‘ 23 AND a.cust_industry = ‘2‘ 24 AND a.cust_level = ‘22‘ 25 LIMIT 0, 10
6.2. 创建pojo开发
public class Customer {
private Long cust_id;
private String cust_name;
private Long cust_user_id;
private Long cust_create_id;
private String cust_source;
private String cust_industry;
private String cust_level;
private String cust_linkman;
private String cust_phone;
private String cust_mobile;
private String cust_zipcode;
private String cust_address;
private Date cust_createtime;
get/set。。。。。。
}
6.3. 实现DAO
分析：
1. 前台发起请求,需要接收请求过来的查询条件数据，可以使用pojo接收数据。需要依此编写查询逻辑。
2. 前台需要分页显示，根据准备好的分页实现，应该返回分页类Page，而创建Page分页类需要数据总条数，所以也需要查询数据总条数的逻辑。
根据分析，DAO需要编写两个方法:
1. 需要根据条件分页查询客户信息
2. 需要根据条件查询数据总条数
6.3.1. 创建QueryVo
需要编写QueryVo，里面包含查询条件属性和分页数据。
创建接受请求参数的QueryVo：
public class QueryVo {
private String custName;
private String custSource;
private String custIndustry;
private String custLevel;
// 当前页码数
private Integer page = 1;
// 数据库从哪一条数据开始查
private Integer start;
// 每页显示数据条数
private Integer rows = 10;
get/set。。。。。。
}
6.3.2. Mapper
创建CustomerMapper 接口
public interface CustomerMapper {
/**
* 根据queryVo分页查询数据
*
* @param queryVo
* @return
*/
List<Customer> queryCustomerByQueryVo(QueryVo queryVo);
/**
* 根据queryVo查询数据条数
*
* @param queryVo
* @return
*/
int queryCountByQueryVo(QueryVo queryVo);
}
6.3.3. Mapper.xml
创建CustomerMapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.itcast.crm.mapper.CustomerMapper">
<sql id="customerQueryVo">
<where>
<if test="custName != null and custName != ‘‘">
AND a.cust_name LIKE ‘%${custName}%‘
</if>
<if test="custSource != null and custSource != ‘‘">
AND a.cust_source = #{custSource}
</if>
<if test="custIndustry != null and custIndustry != ‘‘">
AND a.cust_industry = #{custIndustry}
</if>
<if test="custLevel != null and custLevel != ‘‘">
AND a.cust_level = #{custLevel}
</if>
</where>
</sql>
<!-- 根据queryVo分页查询数据 -->
<select id="queryCustomerByQueryVo" parameterType="cn.itcast.crm.pojo.QueryVo"
resultType="cn.itcast.crm.pojo.Customer">
SELECT
a.cust_id,
a.cust_name,
a.cust_user_id,
a.cust_create_id,
b.dict_item_name cust_source,
c.dict_item_name cust_industry,
d.dict_item_name cust_level,
a.cust_linkman,
a.cust_phone,
a.cust_mobile,
a.cust_zipcode,
a.cust_address,
a.cust_createtime
FROM
customer a
LEFT JOIN base_dict b ON a.cust_source = b.dict_id
LEFT JOIN base_dict c ON a.cust_industry = c.dict_id
LEFT JOIN base_dict d ON a.cust_level = d.dict_id
<include refid="customerQueryVo" />
<if test="start != null">
LIMIT #{start}, #{rows}
</if>
</select>
<!-- 根据queryVo查询数据条数 -->
<select id="queryCountByQueryVo" parameterType="cn.itcast.crm.pojo.QueryVo"
resultType="int">
SELECT count(1) FROM customer a
<include refid="customerQueryVo" />
</select>
</mapper>
6.4. 实现service
6.4.1. 接口
编写接口CustomerService
public interface CustomerService {
/**
* 根据条件分页查询客户
*
* @param queryVo
* @return
*/
Page<Customer> queryCustomerByQueryVo(QueryVo queryVo);
}
6.4.2. 实现类
编写接口实现类CustomerServiceImpl
@Service
public class CustomerServiceImpl implements CustomerService {
@Autowired
private CustomerMapper customerMapper;
@Override
public Page<Customer> queryCustomerByQueryVo(QueryVo queryVo) {
// 设置查询条件,从哪一条数据开始查
queryVo.setStart((queryVo.getPage() - 1) * queryVo.getRows());
// 查询数据结果集
List<Customer> list = this.customerMapper.queryCustomerByQueryVo(queryVo);
// 查询到的数据总条数
int total = this.customerMapper.queryCountByQueryVo(queryVo);
// 封装返回的page对象
Page<Customer> page = new Page<>(total, queryVo.getPage(), queryVo.getRows(), list);
return page;
}
}
6.5. 实现Controller
改造Controller的方法
@RequestMapping("list")
public String queryCustomerList(QueryVo queryVo, Model model) {
try {
// 解决get请求乱码问题
if (StringUtils.isNotBlank(queryVo.getCustName())) {
queryVo.setCustName(new String(queryVo.getCustName().getBytes("ISO-8859-1"), "UTF-8"));
}
} catch (Exception e) {
e.printStackTrace();
}
// 客户来源
List<BaseDict> fromType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_FROM_TYPE);
// 所属行业
List<BaseDict> industryType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_INDUSTRY_TYPE);
// 客户级别
List<BaseDict> levelType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_LEVEL_TYPE);
// 把前端页面需要显示的数据放到模型中
model.addAttribute("fromType", fromType);
model.addAttribute("industryType", industryType);
model.addAttribute("levelType", levelType);
// 分页查询数据
Page<Customer> page = this.customerService.queryCustomerByQueryVo(queryVo);
// 把分页查询的结果放到模型中
model.addAttribute("page", page);
// 数据回显
model.addAttribute("custName", queryVo.getCustName());
model.addAttribute("custSource", queryVo.getCustSource());
model.addAttribute("custIndustry", queryVo.getCustIndustry());
model.addAttribute("custLevel", queryVo.getCustLevel());
return "customer";
}
7. 修改客户信息
7.1. 需求
页面效果如下图：
1、客户列表中点击“修改”按钮弹出客户信息修改窗，并初始化客户信息
2、点击“保存修改”按钮将修改后的结果保存到数据库中
7.2. 实现编辑数据回显
在客户列表显示中，可以点击修改按钮，弹出修改界面，打开浏览器的开发者工具，发现当点击修改按钮，会发起一个请求
如下图方式进行查看
分析这里应该是发起请求到后台，获取该用户的详细信息，在页面上可以回显
复制请求路径中的edit.action，在customer.jsp页面中搜索，找到请求逻辑
找到的代码如下图：
发现这里是一个Ajax请求，根据这个请求我们可以开发后台逻辑，提供给前端页面进行调用
7.3. 回显功能实现
7.3.1. Mapper接口
在CustomerMapper添加方法
/** * 根据id查询客户 * * @param id * @return */ Customer queryCustomerById(Long id);
7.3.2. Mapper.xml
在CustomerMapper.xml编写sql
<!-- 根据id查询用户 -->
<select id="queryCustomerById" resultType="cn.itcast.crm.pojo.Customer">
SELECT * FROM customer WHERE cust_id = #{id}
</select>
7.3.3. Service接口
编写CustomerService.接口方法
/** * 根据id查询数据 * * @param id * @return */ Customer queryCustomerById(Long id);
7.3.4. Service接口实现类
在CustomerServiceImpl实现接口方法
@Override
public Customer queryCustomerById(Long id) {
Customer customer = this.customerMapper.queryCustomerById(id);
return customer;
}
7.3.5. Controller
在CustomerController编写方法
/**
* 根据id查询用户,返回json格式数据
*
* @param id
* @return
*/
@RequestMapping("edit")
@ResponseBody
public Customer queryCustomerById(Long id) {
Customer customer = this.customerService.queryCustomerById(id);
return customer;
}
7.4. 实现编辑客户数据
在编辑框，点击保存修改按钮，应该进行数据保存，如下图所示：
发起请求如下图：
在页面找到的请求逻辑是：
function updateCustomer() {
$.post("<%=basePath%>customer/update.action",$("#edit_customer_form").serialize(),function(data){
alert("客户信息更新成功！");
window.location.reload();
});
}
7.5. 编辑功能实现
7.5.1. Mapper接口
在CustomerMapper添加方法
/** * 根据id编辑客户 * * @param customer */ void updateCustomerById(Customer customer);
7.5.2. Mapper.xml
在CustomerMapper.xml编写sql
<select id="updateCustomerById" parameterType="cn.itcast.crm.pojo.Customer">
UPDATE `customer`
SET
<if test="cust_name !=null and cust_name != ‘‘">
`cust_name` = #{cust_name},
</if>
<if test="cust_user_id !=null">
`cust_user_id` = #{cust_user_id},
</if>
<if test="cust_create_id !=null">
`cust_create_id` = #{cust_create_id},
</if>
<if test="cust_source !=null and cust_source != ‘‘">
`cust_source` = #{cust_source},
</if>
<if test="cust_industry !=null and cust_industry != ‘‘">
`cust_industry` = #{cust_industry},
</if>
<if test="cust_level !=null and cust_level != ‘‘">
`cust_level` = #{cust_level},
</if>
<if test="cust_linkman !=null and cust_linkman != ‘‘">
`cust_linkman` = #{cust_linkman},
</if>
<if test="cust_phone !=null and cust_phone != ‘‘">
`cust_phone` = #{cust_phone},
</if>
<if test="cust_mobile !=null and cust_mobile != ‘‘">
`cust_mobile` = #{cust_mobile},
</if>
<if test="cust_zipcode !=null and cust_zipcode != ‘‘">
`cust_zipcode` = #{cust_zipcode},
</if>
<if test="cust_address !=null and cust_address != ‘‘">
`cust_address` = #{cust_address},
</if>
`cust_createtime` = NOW()
WHERE
(`cust_id` = #{cust_id});
</select>
7.5.3. Service接口
编写CustomerService.接口方法
/**
* 根据id编辑客户数据
*
* @param customer
*/
void updateCustomerById(Customer customer);
7.5.4. Service接口实现类
在CustomerServiceImpl实现接口方法
@Override
public void updateCustomerById(Customer customer) {
this.customerMapper.updateCustomerById(customer);
}
7.5.5. Controller
在CustomerController编写方法
需要正确的响应，要告诉前端更新成功。返回值有没有都可以。
这里需要加@ResponseBody注解，使其不走视图解析器。
/**
* 根据id查询用户,返回更新后客户的json格式数据
*
* @param id
* @return
*/
@RequestMapping("update")
@ResponseBody
public String updateCustomerById(Customer customer) {
Customer result = this.customerService.updateCustomerById(customer);
return "OK";
}
8. 删除客户
8.1. 需求分析
点击客户列表中的删除按钮，提示“警告信息”，如下图
如下图，点击确定后删除用户信息，并刷新页面。
发起的请求如下图：
搜索前端jsp页面逻辑找到如下代码：
function deleteCustomer(id) {
if(confirm(‘确实要删除该客户吗?‘)) {
$.post("<%=basePath%>customer/delete.action",{"id":id},function(data){
alert("客户删除更新成功！");
window.location.reload();
});
}
}
8.2. 功能开发
8.2.1. Mapper接口
在CustomerMapper添加方法
/** * 根据id删除用户 * * @param id */ void deleteCustomerById(Long id);
