SpringMVC4.1.6整合MyBatis3.4.1的标准配置

工程结构



web.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"

contextConfigLocation配置springmvc加载的配置文件(配置处理映射器，适配器等)

SqlMapConfig.xml的配置（MyBatis的配置）

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 由于springmvc和mybatis的整合进行mapper扫描，这里不需要配置
必须遵循：mapper.xml和mapper.java文件同名且在同一个目录
-->
<mappers>
<package name="cn.itcast.ssm.mapper"/>
</mappers>
</configuration>

applicationContext.xml的配置（Spring的配置）

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!-- 加载配置文件 -->
<context:property-placeholder location="classpath:db.properties"/>
<!-- 配置数据源 ,数据库链接信息,两种数据源都可以
jdbc:	org.springframework.jdbc.datasource.DriverManagerDataSource

-->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>

<!-- 声明式事务配置 开始 -->
<!-- 配置事务管理器 -->
<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 配置事务通知 -->
<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<!-- 配置哪些方法使用什么样的事务,配置事务的传播特性,
propagation="REQUIRED",如果当前没有事务，就新建一个事务，如果已经存在一个事务中，加入到这个事务中。这是最常见的选择。 -->

<tx:method name="insertUser" propagation="REQUIRED" rollback-for="Throwable"/>
<tx:method name="deleteUserById" propagation="REQUIRED" rollback-for="Throwable"/><!-- 当deleteUserById发生异常时回滚 -->
<tx:method name="*" propagation="REQUIRED" rollback-for="Throwable"/> <!-- 配置所有方法回滚 -->

<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/>
</aop:config>
<!-- 声明式事务配置 结束 -->

<!-- 配置SqlSessionFactory,目的是的到SqlSessionFactory对象-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<!-- 加载SqlMapConfig.xml配置文件 -->
<property name="configLocation" value="classpath:SqlMapConfig.xml"></property>
</bean>

<!-- 配置Mapper的扫描器，相当于SqlMapConfig.xml文件中的
<mappers>
<package name="cn.itcast.ssm.mapper"/>
</mappers>
-->
<!--
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
如果需要扫描多个包，中间用逗号隔开
<property name="basePackage" value="cn.itcast.ssm.mapper"></property>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>

<import resource="config/spring/user.xml"/>

</beans>

user.xml的配置（在applicationContext.xml中导入的Spring文件）

<?xml version="1.0" encoding="UTF-8"?>

mvc:annotation-driven默认加载了很多参数绑定方法，

<mvc:annotation-driven/>

<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean>
</beans>

db.properties的配置

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc\:mysql\://localhost\:3306/springmvc
jdbc.username=root
jdbc.password=mysqladmin

log4j.properties

# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# MyBatis logging configuration...
log4j.logger.org.mybatis.example.BlogMapper=TRACE
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

其余的java比较简单，此处省略，本文章重点是SpringMVC与Mybatis的整合
