eclipse下maven springMVC 整合 mybatis

参考文档:http://blog.csdn.net/zhshulin/article/details/37956105

1.搭建maven工程,具体参见我另一篇博客:http://www.cnblogs.com/kangyun/p/5455108.html

进行到配置web.xml之前那一步就可以了

2.maven导入依赖,我的pom.xml文件的依赖如下所示:

pom.xml 依赖部分

2.整合mybatis

首先配置数据库连接配置文件,在src/main/resources下创建文件:jdbc.properties

driver=com.mysql.jdbc.Driver

url=jdbc:mysql://localhost:3306/db_test

username=root

password=

initialSize=0

maxActive=20

maxIdle=20

minIdle=1

maxWait=60000

依然是在该目录下,创建spring-mybatis.xml文件

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

 8                         http://www.springframework.org/schema/context
 9                         http://www.springframework.org/schema/context/spring-context-3.1.xsd
10                         http://www.springframework.org/schema/mvc
11                         http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
12     <!-- 自动扫描 -->
13     <context:component-scan base-package="com.practice.prac" />
14     <!-- 引入配置文件 -->
15     <bean id="propertyConfigurer"
16         class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
17         <property name="location" value="classpath:jdbc.properties" />
18     </bean>
19
20     <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
21         destroy-method="close">
22         <property name="driverClassName" value="${driver}" />
23         <property name="url" value="${url}" />
24         <property name="username" value="${username}" />
25         <property name="password" value="${password}" />
26         <!-- 初始化连接大小 -->
27         <property name="initialSize" value="${initialSize}"></property>
28         <!-- 连接池最大数量 -->

34         <!-- 获取连接最大等待时间 -->
35         <property name="maxWait" value="${maxWait}"></property>
36     </bean>
37
38     <!-- spring和MyBatis完美整合,不需要mybatis的配置映射文件 -->
39     <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
40         <property name="dataSource" ref="dataSource" />
41         <!-- 自动扫描mapping.xml文件 -->
42         <property name="mapperLocations" value="classpath:com/practice/prac/mapping/*.xml"></property>
43     </bean>
44
45     <!-- DAO接口所在包名,Spring会自动查找其下的类 -->
46     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
47         <property name="basePackage" value="com.practice.prac.dao" />
48         <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
49     </bean>
50
51     <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
52     <bean id="transactionManager"
53         class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
54         <property name="dataSource" ref="dataSource" />
55     </bean>
56
57 </beans>

spring-mybatis.xml

配置log4j,依然在该目录下,创建log4j.properties

log4j.rootLogger=INFO,Console,File

log4j.appender.Console=org.apache.log4j.ConsoleAppender

log4j.appender.Console.Target=System.out

log4j.appender.Console.layout = org.apache.log4j.PatternLayout

log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

log4j.appender.File = org.apache.log4j.RollingFileAppender

log4j.appender.File.File = logs/ssm.log

log4j.appender.File.MaxFileSize = 10MB

log4j.appender.File.Threshold = ALL

log4j.appender.File.layout = org.apache.log4j.PatternLayout

log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

以上就是mybatis的全部配置,为了验证,我们现在使用junit测试后台部分。

首先创建数据表:

 1 CREATE TABLE `user_t` (
 2   `id` int(11) NOT NULL AUTO_INCREMENT,
 3   `user_name` varchar(40) NOT NULL,
 4   `password` varchar(255) NOT NULL,
 5   `age` int(4) NOT NULL,
 6   PRIMARY KEY (`id`)
 7 ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
 8
 9 /*Data for the table `user_t` */
10
11 insert  into `user_t`(`id`,`user_name`,`password`,`age`) values (1,‘测试‘,‘sfasgfaf‘,24);  

sql

然后配置mybatis-generator自动创建代码,参考这篇博客:

自动创建dao、mapper和model之后,自己写service接口和serviceImpl:

1 package com.practice.prac.service;
2
3 import com.practice.prac.model.User;
4
5 public interface IUserService {
6     public User getUserById(int userId);
7 }

IUserService

 1 package com.practice.prac.service.Impl;
 2
 3 import javax.annotation.Resource;
 4
 5 import org.springframework.stereotype.Service;
 6
 7 import com.practice.prac.dao.UserMapper;
 8 import com.practice.prac.model.User;
 9 import com.practice.prac.service.IUserService;
10
11 @Service("userService")
12 public class UserServiceImpl implements IUserService{
13
14     @Resource
15     private UserMapper userMapper;
16
17     @Override
18     public User getUserById(int userId) {
19
20         return userMapper.selectByPrimaryKey(userId);
21     }
22
23 }

UserServiceImpl

然后在src/test/java目录下创建包:com.practice/prac/service/Impl

在该目录下创建测试文件:

 1 package com.practice.prac.service.Impl;
 2
 3 import javax.annotation.Resource;
 4
 5 import org.apache.log4j.Logger;
 6 import org.junit.Test;
 7 import org.junit.runner.RunWith;
 8 import org.springframework.test.context.ContextConfiguration;
 9 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
10
11 import com.alibaba.fastjson.JSON;
12 import com.practice.prac.model.User;
13 import com.practice.prac.service.IUserService;
14
15 @RunWith(SpringJUnit4ClassRunner.class)        //表示继承了SpringJUnit4ClassRunner类
16 @ContextConfiguration(locations = {"classpath:spring-mybatis.xml"})
17
18 public class TestMyBatis {
19     private static Logger logger = Logger.getLogger(TestMyBatis.class);
20     @Resource
21     private IUserService userService = null;
22     @Test
23     public void test1() {
24         User user = userService.getUserById(1);
25         logger.info(JSON.toJSONString(user));
26     }
27 }

TestMyBatis

右键测试文件,run as junit 测试成功

至此,mybatis整合成功。

3.整合springMVC

在src/main/resources目录下创建文件spring-servlet.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
 4     xmlns:context="http://www.springframework.org/schema/context"
 5     xmlns:mvc="http://www.springframework.org/schema/mvc"
 6     xsi:schemaLocation="http://www.springframework.org/schema/beans
 7                         http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
 8                         http://www.springframework.org/schema/context
 9                         http://www.springframework.org/schema/context/spring-context-3.1.xsd
10                         http://www.springframework.org/schema/mvc
11                         http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
12
13     <mvc:annotation-driven />
14
15     <!-- 自动扫描该包,使SpringMVC认为包下用了@controller注解的类是控制器 -->
16     <context:component-scan base-package="com.practice.prac.controller" />
17
18     <!-- 定义跳转的文件的前后缀 ,视图模式配置-->
19     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
20         <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀,变成一个 可用的url地址 -->
21         <property name="prefix" value="/WEB-INF/view/" />
22         <property name="suffix" value=".jsp" />
23     </bean>
24 </beans>

spring-servlet.xml

ps:原博客这里有问题,启动后访问不了controller,加了<mvc:annotation-driven />这句后才能使用,其他地方也做了一些修改,主要是去掉了jackson的配置,因为原博是3.x的springmvc框架,我这里是4.x的,因此jackson报错,只好删掉

然后配置web.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 3     xmlns="http://java.sun.com/xml/ns/javaee"
 4     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
 5     version="3.0">
 6     <display-name>Archetype Created Web Application</display-name>
 7     <!-- Spring和mybatis的配置文件 -->
 8     <context-param>
 9         <param-name>contextConfigLocation</param-name>
10         <param-value>classpath:spring-mybatis.xml</param-value>
11     </context-param>
12     <!-- 编码过滤器 -->
13     <filter>
14         <filter-name>encodingFilter</filter-name>
15         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
16         <async-supported>true</async-supported>
17         <init-param>
18             <param-name>encoding</param-name>
19             <param-value>UTF-8</param-value>
20         </init-param>
21     </filter>
22     <filter-mapping>
23         <filter-name>encodingFilter</filter-name>
24         <url-pattern>/*</url-pattern>
25     </filter-mapping>
26     <!-- Spring监听器 -->
27     <listener>
28         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
29     </listener>
30     <!-- 防止Spring内存溢出监听器 -->
31     <listener>
32         <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
33     </listener>
34
35     <!-- Spring MVC servlet -->
36     <servlet>
37         <servlet-name>SpringMVC</servlet-name>
38         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
39         <init-param>
40             <param-name>contextConfigLocation</param-name>
41             <param-value>classpath:spring-servlet.xml</param-value>
42         </init-param>
43         <load-on-startup>1</load-on-startup>
44         <async-supported>true</async-supported>
45     </servlet>
46     <servlet-mapping>
47         <servlet-name>SpringMVC</servlet-name>
48         <url-pattern>/</url-pattern>
49     </servlet-mapping>
50
51 </web-app>

web.xml

这样就整合完成了,下面创建一个jsp页面和一个controller来验证:

 1 package com.practice.prac.controller;
 2
 3 import javax.annotation.Resource;
 4 import javax.servlet.http.HttpServletRequest;
 5 import javax.servlet.http.HttpServletResponse;
 6
 7 import org.springframework.ui.ModelMap;
 8 import org.springframework.web.bind.annotation.RequestMapping;
 9 import org.springframework.web.bind.annotation.RequestMethod;
10 import org.springframework.web.bind.annotation.RestController;
11 import org.springframework.web.servlet.ModelAndView;
12
13 import com.practice.prac.model.User;
14 import com.practice.prac.service.IUserService;
15
16 @RestController
17 @RequestMapping(value = "show/")
18 public class TestController {
19     @Resource
20     private IUserService userService;
21
22     @RequestMapping(value = "/index", method = RequestMethod.GET)
23     public ModelAndView showIndex(HttpServletRequest request,HttpServletResponse response){
24         ModelMap modelMap = new ModelMap();
25         User user = userService.getUserById(1);
26         modelMap.put("user", user);
27         return new ModelAndView("/index",modelMap);
28     }
29 }

TestController

 1 <%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
 2
 3 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
 4 <html>
 5   <head>
 6     <title>测试</title>
 7   </head>
 8
 9   <body>
10     ${user.userName}
11   </body>
12 </html>

index.jsp

把项目放到tomcat下运行,在浏览器中输入:http://localhost:8080/prac/show/index

整合成功!
