		</dependency>

	</dependencies>

2.配置文件内容如下

在src/main/resources创建spring.xml文件，内容如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="

	http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
	http://www.springframework.org/schema/tx 
	http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
	http://www.springframework.org/schema/aop 
	http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
	">

	<!-- 配置数据源 -->
	<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
		init-method="init" destroy-method="close">
		<!-- 基本属性 url、user、password -->
		<property name="url" value="${url}" />
		<property name="username" value="${username}" />
		<property name="password" value="${password}" />

		<!-- 配置初始化大小、最小、最大 -->
		<property name="initialSize" value="1" />

		<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
		<property name="minEvictableIdleTimeMillis" value="300000" />

		<property name="validationQuery" value="SELECT 'x'" />
		<property name="testWhileIdle" value="true" />
		<property name="testOnBorrow" value="false" />
		<property name="testOnReturn" value="false" />

		<!-- 打开PSCache，并且指定每个连接上PSCache的大小 -->
		<property name="poolPreparedStatements" value="true" />
		<property name="maxPoolPreparedStatementPerConnectionSize"
			value="20" />

		<!-- 配置监控统计拦截的filters，去掉后监控界面sql无法统计 -->
		<property name="filters" value="stat" />
	</bean>

	<!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->  
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
        <property name="dataSource" ref="dataSource" />  
        <!-- 自动扫描mapping.xml文件 -->  
        <property name="mapperLocations" value="classpath:com/cygoat/mapper/*.xml"></property>  
    </bean>  
  
    <!-- DAO接口所在包名，Spring会自动查找其下的类 -->  
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  
        <property name="basePackage" value="com.cygoat.dao" />  
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>  
    </bean>  
  
    <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->  
    <bean id="transactionManager"  
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
        <property name="dataSource" ref="dataSource" />  
    </bean>  
</beans>



jdbc连接 
hibernate.dialect=org.hibernate.dialect.MySQLDialect
driverClassName=com.mysql.jdbc.Driver
validationQuery=SELECT 1
url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8
username=root
password=lxy123


hibernate.hbm2ddl.auto=update
hibernate.show_sql=true
hibernate.format_sql=true

4.maven集成mybatis代码生成器

1.在pom中增加mybatis插件 
<plugin>  
                <groupId>org.mybatis.generator</groupId>  
                <artifactId>mybatis-generator-maven-plugin</artifactId>  
                <version>1.3.2</version>  
                <executions>  
                    <execution>  
                        <id>Generate MyBatis Artifacts</id>  
                        <goals>  
                            <goal>generate</goal>  
                        </goals>  
                    </execution>  
                </executions>  
                <configuration>  
                    <verbose>true</verbose>  
                    <overwrite>true</overwrite>  
                    <!-- <jdbcDriver>com.mysql.jdbc.Driver</jdbcDriver> -->  
                    <!-- <jdbcURL>jdbc:mysql://127.0.0.1:3306/test</jdbcURL> -->  
                    <!-- <jdbcUserId>test</jdbcUserId> -->  
                    <!-- <jdbcPassword>test</jdbcPassword> -->  
                </configuration>  
                <dependencies>  
                    <dependency>  
                        <groupId>mysql</groupId>  
                        <artifactId>mysql-connector-java</artifactId>  
                        <version>5.1.6</version>  
                    </dependency>  
                    <dependency>  
                        <groupId>org.mybatis.generator</groupId>  
                        <artifactId>mybatis-generator-core</artifactId>  
                        <version>1.3.2</version>  
                    </dependency>  
                    <dependency>  
                        <groupId>org.mybatis</groupId>  
                        <artifactId>mybatis</artifactId>  
                        <version>3.2.8</version>  
                    </dependency>  
                </dependencies>  
            </plugin>

2.在src/main/resources下创建generatorConfig.xml，文件内容如下 
<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE generatorConfiguration  
  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"  
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">  
<generatorConfiguration>  
    <!-- 数据库驱动-->  
    <context id="DB2Tables"  targetRuntime="MyBatis3">  
        <commentGenerator>  
            <property name="suppressDate" value="true"/>  
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->  
            <property name="suppressAllComments" value="true"/>  
        </commentGenerator>  
        <!--数据库链接URL，用户名、密码 -->  
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/test" userId="root" password="lxy123">  
        </jdbcConnection>  
        <javaTypeResolver>  
            <property name="forceBigDecimals" value="false"/>  
        </javaTypeResolver>  
        <!-- 生成模型的包名和位置-->  
        <javaModelGenerator targetPackage="com.cygoat.model" targetProject="src/main/java">  
            <property name="enableSubPackages" value="true"/>  
            <property name="trimStrings" value="true"/>  
        </javaModelGenerator>  
        <!-- 生成映射文件的包名和位置-->  
        <sqlMapGenerator targetPackage="com.cygoat.mapper" targetProject="src/main/java">  
            <property name="enableSubPackages" value="true"/>  
        </sqlMapGenerator>  
        <!-- 生成DAO的包名和位置-->  
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.cygoat.dao" targetProject="src/main/java">  
            <property name="enableSubPackages" value="true"/>  
        </javaClientGenerator>
        
        <!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->  
        <table tableName="sys_user" domainObjectName="SysUser" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
    </context>  
</generatorConfiguration>


3.执行命令生成代码mybatis-generator:generate


5.junit测试

1.新增com.cygoat.service包 SysUserManager.java 
package com.cygoat.service;

import com.cygoat.model.SysUser;

public interface SysUserManager {

	public SysUser get(String id);

}
SysUserManagerImpl.java 
package com.cygoat.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.cygoat.dao.SysUserMapper;
import com.cygoat.model.SysUser;
import com.cygoat.service.SysUserManager;

@Service
public class SysUserManagerImpl implements SysUserManager {
	@Autowired
	private SysUserMapper sysUserMapper;

	public SysUser get(String id){
		return sysUserMapper.selectByPrimaryKey(id);
	}
}

2.junit测试代码 src/test/java下创建SysUserManagerImplTest.java文件，代码如下 
package com.cygoat.service;

import static org.junit.Assert.*;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.cygoat.service.SysUserManager;

public class SysUserManagerImplTest {
	
	private ApplicationContext ac;

	@Before
	public void setUp() throws Exception {
		ac = new ClassPathXmlApplicationContext("spring.xml");
	}

	@After
	public void tearDown() throws Exception {
	}

	@Test
	public void testGet() {
		SysUserManager obj = (SysUserManager)ac.getBean("sysUserManagerImpl");
		assertNotNull("not null", obj.get("1"));
	}

}
至此，完成了spring和mybatis的整合

6.spring和springMvc整合


6.1.配置spring-mvc.xml

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

	<!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 -->
	<context:component-scan base-package="com.alan.system.controller" />

	    <!-- 注解请求映射  -->
    <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">        
		<property name="interceptors">
		    <list>  
		    	<!-- <ref bean="logNDCInteceptor"/>   日志拦截器，这是你自定义的拦截器

		</property>        
	</bean>  	
	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

		</property>  
	</bean>  
	<bean id="byteArray_hmc" class="org.springframework.http.converter.ByteArrayHttpMessageConverter" /><!-- 处理.. -->

	<bean id="jackson_hmc" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" /><!-- 处理json-->

	<!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->
	<!-- <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> 
		<property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value>

		<property name="prefix" value="/jsp/" />
		<property name="suffix" value=".jsp" />
	</bean>

	<!-- json转换器 -->
	<!-- <bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> 
		<property name="supportedMediaTypes" value="application/json" /> </bean> -->
</beans>

6.2.修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	
	<!-- 编码过滤器 -->

			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	<!-- Spring MVC servlet -->

	</servlet-mapping>
	<session-config>
		<session-timeout>10</session-timeout>
	</session-config>
	<!-- Spring和mybatis的配置文件 -->   
	<context-param>
		<param-name>contextConfigLocation</param-name>

	</context-param>
	<!-- Spring监听器  -->  
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- 防止Spring内存溢出监听器 -->  
    <listener>  
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>  
    </listener> 

	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

6.3.测试

新增SysUserController类 
package com.cygoat.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.cygoat.service.SysUserManager;

@Controller
@RequestMapping("sysUser")
public class SysUserController {

	@Autowired
	private SysUserManager sysUserManager;
	
	@RequestMapping("get")
	@ResponseBody
	public Object get(String id){
		return sysUserManager.get(id);
	}
}
启动tomcat，在浏览器输入http://localhost:8080/SSM/sysUser/get.shtml?id=1


至此，已完成了spring、springmvc、mybatis整合
