7、Spring+Struts2+MyBaits(无映射接口实现类)

1、创建userinfo.sql数据库脚本

 1  create table userinfo
 2 (id number(4),
 3 name varchar2(50),
 4 password varchar2(20),
 5 telephone varchar2(15),
 6 isadmin varchar2(5));
 7
 8  --4.2 用户表序列
 9  create sequence seq_userinfo;
10  alter table userinfo add constraint pk_userinfo_id primary key(id);
11
12  insert into userinfo values(seq_userinfo.nextval,‘holly‘,‘123‘,‘134518024
13 ‘,‘是‘);
14  commit;

userinfo.sql

2、创建如下项目结构

3、在src的com.bean包下创建UserInfo.java

 1 package com.bean;
 2 /**
 3  * 用户信息表
 4  * @author Holly老师
 5  *
 6  */
 7 public class UserInfo {
 8     private Integer id;//编号
 9     private String name; //姓名
10     private String password; //密码
11     private String telephone; //电话
12     private String isadmin; //是否是管理员
13
14     public UserInfo() {
15
16     }
17     public UserInfo(Integer id, String name, String password, String telephone,
18             String isadmin) {
19         this.id = id;
20         this.name = name;
21         this.password = password;
22         this.telephone = telephone;
23         this.isadmin = isadmin;
24     }
25     public Integer getId() {
26         return id;
27     }
28     public void setId(Integer id) {
29         this.id = id;
30     }
31     public String getName() {
32         return name;
33     }
34     public void setName(String name) {
35         this.name = name;
36     }
37     public String getPassword() {
38         return password;
39     }
40     public void setPassword(String password) {
41         this.password = password;
42     }
43     public String getTelephone() {
44         return telephone;
45     }
46     public void setTelephone(String telephone) {
47         this.telephone = telephone;
48     }
49     public String getIsadmin() {
50         return isadmin;
51     }
52     public void setIsadmin(String isadmin) {
53         this.isadmin = isadmin;
54     }
55     @Override
56     public String toString() {
57         return "UserInfo [id=" + id + ", isadmin=" + isadmin + ", name=" + name
58                 + ", password=" + password + ", telephone=" + telephone + "]";
59     }
60
61
62 }

UserInfo.java

4、在src的com.dao包下创建UserInfoDao.java

 1 package com.dao;
 2
 3 import java.util.List;
 4
 5 import com.bean.UserInfo;
 6 /**
 7  * mybatis映射文件的dao接口
 8  * @author Holly老师
 9  *
10  */
11 public interface UserInfoDao {
12     /**
13      * 1.根据对象去查询对象
14      * @return
15      */
16     public UserInfo findUser(UserInfo userinfo);
17     /**
18      * 2.查询所有
19      * @return
20      */
21     public List<UserInfo> findAll();
22     /**
23      * 3.根据id查询
24      */
25     public UserInfo findById(int id);
26     /**
27      * 4.保存对象
28      * @param userinfo
29      */
30     public void saveObj(UserInfo userinfo);
31     /**
32      * 5.修改对象
33      */
34     public void updateObj(UserInfo userinfo);
35     /**
36      * 6.删除对象
37      * @param id
38      */
39     public void deleteObj(int id);
40
41
42
43 }

UserInfoDao.java

5、在src的com.dao包下创建UserInfoDao.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
 3 <mapper namespace="com.dao.UserInfoDao">
 4 <!--
 5   <resultMap type="userinfo" id="userMap">

21   </select>
22
23   <!-- 3.根据id查询 -->
24   <select id="findById" parameterType="int" resultType="userinfo">
25      select * from userinfo where id=#{id}
26   </select>
27
28   <!-- 4.根据id删除 -->
29   <delete id="deleteObj" parameterType="int">
30      delete from userinfo where id=#{id}
31   </delete>
32
33   <!-- 5.修改 -->
34   <update id="updateObj" parameterType="userinfo">
35     update userinfo set name=#{name},password=#{password},telephone=#{telephone},isadmin=#{isadmin} where id=#{id}
36   </update>
37
38   <!-- 6.保存 -->
39   <insert id="saveObj" parameterType="userinfo">
40      insert into userinfo values(seq_userinfo.nextval,#{name},#{password},#{telephone},#{isadmin})
41   </insert>
42
43
44 </mapper>

UserInfoDao.xml

 2 <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd" >
 3 <configuration>
 4   <!-- mybatis映射文件的别名配置 -->
 5   <typeAliases>
 6     <typeAlias type="com.bean.UserInfo" alias="userinfo"/>
 7   </typeAliases>
 8
 9   <!-- 注册mybatis的映射文件 -->
10   <mappers>
11     <mapper resource="com/dao/UserInfoDao.xml"/>

7、Spring+Struts2+MyBaits(无映射接口实现类)的相关文章

8、Spring+Struts2+MyBaits(Spring注解+jdbc属性文件+log4j属性文件)

一.注解理论 使用注解来构造IoC容器 用注解来向Spring容器注册Bean.需要在applicationContext.xml中注册<context:component-scan base-package=”pagkage1[,pagkage2,…,pagkageN]”/>. 如:在base-package指明一个包 1 <context:component-scan base-package="cn.gacl.java"/> 表明cn.gacl.java包

5、Spring+Struts2+MyBatis+分页（无代理）增删改查

1.创建如下项目结构 2.在src下的com.entity包下创建Dept.java 1 package com.entity; 2 /** 3 * 部门表 4 * @author Holly老师 5 * 6 */ 7 public class Dept { 8 private Integer deptno; //部门编号 9 private String dname; //部门名称 10 private String loc; //位置 11 12 13 public Dept() { 14

MyBatis Spring整合配置映射接口类与映射xml文件

Spring整合MyBatis使用到了mybatis-spring,在配置mybatis映射文件的时候,一般会使用MapperScannerConfigurer,MapperScannerConfigurer会自动扫描basePackage指定的包,找到映射接口类和映射XML文件,并进行注入.配置如下: [html] view plain copy <!-- 数据源 --> <bean id="dataSource" class="com.mchange.v

spring测试junit事务管理及spring面向接口注入和实现类单独注入（无实现接口），实现类实现接口而实现类单独注入否则会报错。

1.根据日志分析,spring junit默认是自动回滚,不对数据库做任何的操作. 18:16:57.648 [main] DEBUG o.s.j.d.DataSourceTransactionManager - Switching JDBC Connection [[email protected]] to manual commit 18:16:57.649 [main] DEBUG o.s.t.c.t.TransactionalTestExecutionListener - No meth

6、Spring+Struts2+MyBatis（mybatis有代理）整合增删改查

1.创建如下的oracle脚本 1 create table userinfo 2 (id number(4), 3 name varchar2(50), 4 password varchar2(20 5 telephone varchar2(15), 6 isadmin varchar2(5)); 7 8 --4.2 用户表序列 9 create sequence seq_userinfo; 10 11 alter table userinfo add constraint pk_userin

Hibernate+Spring+Struts2整合开发中的一个分页显示方案(转载)

分页显示一直是web开发中一大烦琐的难题,传统的网页设计只在一个JSP或者ASP页面中书写所有关于数据库操作的代码,那样做分页可能简单一点,但当把网站分层开发后,分页就比较困难了,下面是我做Spring+Hibernate+Struts2项目时设计的分页代码,与大家分享交流. 1.DAO层接口的设计,在MemberDao接口中定义了如下两个方法: public interface MemberDao{        //省略了其他的代码        /**     * 分页查询     * @
