pom.xml

2.2、创建整合目录

 

 

Mybatis：存放mybatis配置文件

Spring：存放spring以及整合文件

Resource：数据库连接以及log4配置信息

2.3、创建MyBatis配置文件

创建mybatis-config.xml文件位于mybatis目录下

mybatis-config.xml

1 xml version="1.0" encoding="UTF-8" ?>
2 DOCTYPE configuration
3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
4 "http://mybatis.org/dtd/mybatis-3-config.dtd">
5 <configuration>
6 configuration>

该文件主要存mybatis配置。(该配置文件可以不创建)

2.4、创建数据库配置信息

创建db.properties文件位于resource文件夹下

db.properties

1 #数据库连接驱动
2 jdbc.driver=com.mysql.jdbc.Driver
3 #数据库连接url
4 jdbc.url=jdbc:mysql://localhost:3306/woo0nise?characterEncoding=utf-8
5 #数据库用户名
6 jdbc.username=root
7 #数据库密码
8 jdbc.password=root

该配置文件主要存放数据库的配置,也可以存放mybatis配置文件的属性。

2.5、Spring整合mybatis

创建applicationContext-dao.xml文件位于spring文件夹下

applicationContext-dao.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"
 4 xmlns:aop="http://www.springframework.org/schema/aop"
 5 xmlns:context="http://www.springframework.org/schema/context"
 6 xmlns:jdbc="http://www.springframework.org/schema/jdbc"
 7 xmlns:p="http://www.springframework.org/schema/p"

28 bean>
29 
30 <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean"  >

32 <property name="dataSource" ref="dataSource" >property>
33 
34 <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" >property>

36 
37 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" >
38 <property name="basePackage" value="com.test.dao" >property>
39 bean>
40 beans>

applicationContext-dao.xml

该配置文件主要是spring整合mybatis文件。

2.6、Spring事务管理

创建applicationContext-trans.xml位于spring文件夹下

applicationContext-trans.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"

38 pointcut="execution(* com.taotao.service.impl.*.*(..))" />
39 aop:config>
40 beans>

applicationContext-trans.xml

该配置文件主要配置事务以及事务管理和切面(AOP)配置。

2.7、Spring扫描Service的实现类

创建applicationContext-service.xml位于spring文件夹下

applicationContext-service.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"
 4 xmlns:aop="http://www.springframework.org/schema/aop"
 5 xmlns:context="http://www.springframework.org/schema/context"
 6 xmlns:jdbc="http://www.springframework.org/schema/jdbc"
 7 xmlns:p="http://www.springframework.org/schema/p"
 8 xmlns:tx="http://www.springframework.org/schema/tx"
 9 xmlns:util="http://www.springframework.org/schema/util"
10 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
11 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
12 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
13 http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.1.xsd
14 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
15 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.1.xsd">
16 <context:component-scan base-package="com.test.service">context:component-scan>
17 beans>

applicationContext-service.xml

该配置文件主要是用来扫描Service的实现类。

2.8、创建springmvc.xml

创建springmvc.xml文件位于spring文件夹下

springmvc.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"

19 <property name="prefix" value="/WEB-INF/jsp/" />
20 <property name="suffix" value=".jsp" />
21 bean>
22 beans>

2.9、配置web.xml

修改web.xml

 1 xml version="1.0" encoding="UTF-8"?>
 2 <web-app version="3.0" 
 3 xmlns="http://java.sun.com/xml/ns/javaee" 
 4 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

51 web-app>

web.xml

3、测试整合

3.1、创建实体类以及dao层

1、导入mybatis逆向工程

创建com.test.dao和com.test.entity包用于存放生成的文件

 

2、修改generatorConfig.xml文件

 1 xml version="1.0" encoding="UTF-8"?>
 2 DOCTYPE generatorConfiguration
 3   PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
 4   "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
 5  
 6 <generatorConfiguration>
 7 <context id="testTables" targetRuntime="MyBatis3">
 8 <commentGenerator>
 9 
10 <property name="suppressAllComments" value="true" />
11 commentGenerator>
12 
13 <jdbcConnection driverClass="com.mysql.jdbc.Driver"
14 connectionURL="jdbc:mysql://localhost:3306/woo0nise" userId="root"
15 password="root">
16 jdbcConnection>
17 
19 <javaTypeResolver>
20 <property name="forceBigDecimals" value="false" />
21 javaTypeResolver>
22  
23 
24 <javaModelGenerator targetPackage="com.test.entity"
25 targetProject=".\src">
26 
27 <property name="enableSubPackages" value="false" />
28 
29 <property name="trimStrings" value="true" />
30 javaModelGenerator>
31         
32 <sqlMapGenerator targetPackage="com.test.dao" 
33 targetProject=".\src">
34 
35 <property name="enableSubPackages" value="false" />
36 sqlMapGenerator>
37 
38 <javaClientGenerator type="XMLMAPPER"
39 targetPackage="com.test.dao" 
40 targetProject=".\src">
41 
42 <property name="enableSubPackages" value="false" />
43 javaClientGenerator>
44 
45 <table schema="" tableName="user">table>
46 context>
47 generatorConfiguration>

generatorConfig.xml

3、运行GeneratorSqlmap生成实体文件以及mapper文件

 

4、将com.test.dao以及com.tes.entity到本工程中

3.2、创建业务逻辑层

1、创建com.test.service包用于存放业务逻辑层接口类

创建UserService接口文件

 1 package com.test.service;
 2  
 3 import com.test.entity.User;
 4  
 5 /**
 6  * 
Title:UserService
 7  * 
Description:
 8  * 
Company:www.hack-gov.com
 9  * @author 0nise
10  * @date 2017年1月1日 上午12:47:42
11  * @Email [email protected]
12  * @version 1.0
13  */
14 public interface UserService {
15 /**
16  * 新增用户
17  * @author 0nise
18  * @date 2017年1月1日 上午12:48:12
19  * @Email [email protected]
20  * @param user
21  */
22 public int add(User user);
23 }

2、创建com.testservice.impl包用于存放业务逻辑层接口的实现类

创建UserServiceImpl类用于实现UserService接口文件

 1 package com.test.service.impl;
 2  
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.stereotype.Service;
 5  
 6 import com.test.dao.UserMapper;
 7 import com.test.entity.User;
 8 import com.test.service.UserService;
 9 /**
10  * 
Title:UserServiceImpl
11  * 
Description:
12  * 
Company:www.hack-gov.com
13  * @author 0nise
14  * @date 2017年1月1日 上午12:51:34
15  * @Email [email protected]
16  * @version 1.0
17  */
18 @Service
19 public class UserServiceImpl implements UserService {
20 //注入UserMapper
21 @Autowired
22 private UserMapper userMapper;
23  
24 @Override
25 public int add(User user) {
26 try {
27 userMapper.insert(user);
28 return 1;
29 } catch (Exception e) {
30 e.printStackTrace();
31 return -1;
32 }
33 }
34 }

3.3、创建Controller层

3.3.1、创建com.test.controller包用户存放controller

创建UserController

 1 package com.test.controller;
 2  
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.stereotype.Controller;
 5 import org.springframework.web.bind.annotation.RequestMapping;
 6 import com.test.entity.User;
 7 import com.test.service.UserService;
 8  
 9 /**
10  * 
Title:UserController
11  * 
Description:
12  * 
Company:www.hack-gov.com
13  * @author 0nise
14  * @date 2017年1月1日 上午12:55:57
15  * @Email [email protected]
16  * @version 1.0
17  */
18 @Controller
19 public class UserController {
20 //注入UserService
21 @Autowired
22 private UserService userService;
23 @RequestMapping("ok")
24 public String add(){
25 User user = new User();
26 user.setUsername("admin99");
27 user.setUserpwd("admin99");
28 int i = userService.add(user);
29 if(i > 0){
30 System.out.println("ok");
31 }else{
32 System.err.println("error");
33 }
34 return null;
35 }
36 }
