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

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" 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 17 <context:property-placeholder location="classpath:resource/db.properties" /> 18 19 20 <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" 21 destroy-method="close"> 22 <property name="url" value="${jdbc.url}" /> 23 <property name="username" value="${jdbc.username}" /> 24 <property name="password" value="${jdbc.password}" /> 25 <property name="driverClassName" value="${jdbc.driver}" /> 26 <property name="maxActive" value="10" /> 27 <property name="minIdle" value="5" /> 28 bean> 29 30 <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean" > 31 32 <property name="dataSource" ref="dataSource" >property> 33 34 <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" >property> 35 bean> 36 37 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" > 38 <property name="basePackage" value="com.test.dao" >property> 39 bean> 40 beans>
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" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:jdbc="http://www.springframework.org/schema/jdbc" 6 xmlns:p="http://www.springframework.org/schema/p" 7 xmlns:tx="http://www.springframework.org/schema/tx" 8 xmlns:util="http://www.springframework.org/schema/util" 9 xmlns:aop="http://www.springframework.org/schema/aop" 10 xsi:schemaLocation="http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.1.xsd 11 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.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/aop http://www.springframework.org/schema/aop/spring-aop-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 17 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" > 18 19 <property name="dataSource" ref="dataSource" >property> 20 bean> 21 22 <tx:advice id="txAdvice" transaction-manager="transactionManager"> 23 <tx:attributes> 24 <tx:method name="save*" propagation="REQUIRED" /> 25 <tx:method name="insert*" propagation="REQUIRED" /> 26 <tx:method name="add*" propagation="REQUIRED" /> 27 <tx:method name="create*" propagation="REQUIRED" /> 28 <tx:method name="delete*" propagation="REQUIRED" /> 29 <tx:method name="update*" propagation="REQUIRED" /> 30 <tx:method name="find*" propagation="SUPPORTS" read-only="true" /> 31 <tx:method name="select*" propagation="SUPPORTS" read-only="true" /> 32 <tx:method name="get*" propagation="SUPPORTS" read-only="true" /> 33 tx:attributes> 34 tx:advice> 35 36 <aop:config> 37 <aop:advisor advice-ref="txAdvice" 38 pointcut="execution(* com.taotao.service.impl.*.*(..))" /> 39 aop:config> 40 beans>
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>
该配置文件主要是用来扫描Service的实现类。
2.8、创建springmvc.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>
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 }
