整合Spring、SpringMVC、MyBatis
spring+springmvc+mybatis集成
一个核心：将对象交给spring管理。
1新建web项目
2添加项目jar包
spring包见上一篇博客
3建立项目的目录结构
4完成Mapper的集成
和mybatis进行集成，交给spring产生Mapper接口的代理对象。
4.1建立Mapper接口
1 package org.guangsoft.mapper;
2
3 import java.util.List;
4
5 import org.guangsoft.pojo.Privilege;
6
7 public interface PrivilegeMapper
8 {
9 public void addPrivilege(Privilege privilege);
10 public void deletePrivilege(Privilege privilege);
11 public void updatePrivilege(Privilege privilege);
12 public Privilege selectPrivilegeById(Privilege privilege);
13 public List<Privilege> selectAllPrivileges();
14 }
4.2建立Mapper.xml文件
1 <?xml version="1.0" encoding="UTF-8"?>
2 <!DOCTYPE mapper PUBLIC "-//mybatis.org/DTD Mapper 3.0" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
3 <mapper namespace="org.guangsoft.mapper.PrivilegeMapper">
4 <insert id="addPrivilege" parameterType="org.guangsoft.pojo.Privilege">
5 insert into privilege values(null,#{pname})
6 </insert>
7 <delete id="deletePrivilege" parameterType="org.guangsoft.pojo.Privilege">
8 delete from privilege
9 </delete>
10 <delete id="updatePrivilege" parameterType="org.guangsoft.pojo.Privilege">
11 update privilege set pname=#{pname} where pid=#{pid}
12 </delete>
13 <select id="selectPrivilegeById" parameterType="org.guangsoft.pojo.Privilege" resultType="org.guangsoft.pojo.Privilege">
14 select * from privilege where pid=#{pid}
15 </select>
16 <select id="selectAllPrivileges" resultType="org.guangsoft.pojo.Privilege">
17 select * from privilege
18 </select>
19 </mapper>
4.3建立application_mapper.xml
在config下建立：
配置数据库连接池。
管理SqlSessionFactory，注入DataSource
产生Mapper接口的代理对象。
1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans
3 xmlns="http://www.springframework.org/schema/beans"
4 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
5 xmlns:p="http://www.springframework.org/schema/p"
6 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
7
8 <!-- 数据库连接池 -->
9 <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
10 <!-- 注入数据库连接字符串 -->
11 <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
12 <property name="jdbcUrl" value="jdbc:mysql://127.0.0.1:3306/test"></property>
13 <property name="user" value="root"></property>
14 <property name="password" value="root"></property>
15 </bean>
16 <!-- 实例化sessionFactory -->
17 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
18 <!-- 注入数据库连接池 -->
19 <property name="dataSource" ref="dataSource"></property>
20 </bean>
21 <!-- 产生mapper接口的代理对象
22 mapper接口和mapperxml名字必须一样
23 mapper.java和mapper.xml必须在同一目录下
24 产生的代理对象id文件Mapper接口的第一个字母小写
25 -->
26 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
27 <!-- 注入sessionFactory -->
28 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
29 <!-- 注入扫描的包 -->
30 <property name="basePackage" value="org.guangsoft.mapper"></property>
31 </bean>
32 </beans>
5完成service的功能
5.1建立Service接口
1 package org.guangsoft.service;
2
3 import java.util.List;
4
5 import org.guangsoft.pojo.Privilege;
6
7 public interface PrivilegeService
8 {
9 public void addPrivilege(Privilege privilege);
10 public void deletePrivilege(Privilege privilege);
11 public void updatePrivilege(Privilege privilege);
12 public Privilege selectPrivilegeById(Privilege privilege);
13 public List<Privilege> selectAllPrivileges();
14 }
5.2建立业务接口实现类
将实现类的对象纳入spring容器。注入Mapper接口的代理对象
1 package org.guangsoft.service.impl;
2
3 import java.util.List;
4
5 import org.guangsoft.mapper.PrivilegeMapper;
6 import org.guangsoft.pojo.Privilege;
7 import org.guangsoft.service.PrivilegeService;
8 import org.springframework.beans.factory.annotation.Autowired;
9 import org.springframework.stereotype.Service;
10
11 @Service
12 public class PrivilegeServiceImpl implements PrivilegeService
13 {
14 /**
15 * 注入Mapper接口的代理对象
16 */
17 @Autowired
18 private PrivilegeMapper privilegeMapper;
19
20 @Override
21 public void addPrivilege(Privilege privilege)
22 {
23 privilegeMapper.addPrivilege(privilege);
24 }
25
26 @Override
27 public void deletePrivilege(Privilege privilege)
28 {
29 privilegeMapper.deletePrivilege(privilege);
30 }
31
32 @Override
33 public void updatePrivilege(Privilege privilege)
34 {
35 privilegeMapper.updatePrivilege(privilege);
36 }
37
38 @Override
39 public Privilege selectPrivilegeById(Privilege privilege)
40 {
41 return privilegeMapper.selectPrivilegeById(privilege);
42 }
43
44 @Override
45 public List<Privilege> selectAllPrivileges()
46 {
47 return privilegeMapper.selectAllPrivileges();
48 }
49
50 }
5.3建立application_service.xml
扫描service包

9 @Controller
10 public class PrivilegeController
11 {
12 @Autowired
13 private PrivilegeService privilegeService;
14 //定义菜单项求求的方法
15 @RequestMapping("/addPrivilege")
16 public String addPrivilege(Privilege privilege)
17 {
18 privilegeService.addPrivilege(privilege);
19 return "index.jsp";
20 }
21 }
6.2建立springmvc的配置文件
