</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
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" />
<property name="minIdle" value="1" />
<property name="maxActive" value="20" />
<!-- 配置获取连接等待超时的时间 -->
<property name="maxWait" value="60000" />
<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<!-- 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"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">
<!-- 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

<ref bean="string_hmc" />  
<ref bean="resource_hmc" />  
<ref bean="source_hmc" />  
<ref bean="xmlAwareForm_hmc" />  
<ref bean="jaxb2RootElement_hmc" />  
<ref bean="jackson_hmc" />  
</list>  
</property>  
</bean>  
<bean id="byteArray_hmc" class="org.springframework.http.converter.ByteArrayHttpMessageConverter" /><!-- 处理.. -->

<!-- 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>
</list> </property> </bean> -->
<!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
<!-- <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter"
/>json转换器 </list> </property> </bean> -->
<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<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

<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 -->

</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
