今天弄mybatis-pring的事务遇到一个问题,有问题的spring-mybatis.xml配置如下:
<?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:context="http://www.springframework.org/schema/context"       xmlns:aop="http://www.springframework.org/schema/aop"       xmlns:tx="http://www.springframework.org/schema/tx"       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/tx     http://www.springframework.org/schema/tx/spring-tx-3.1.xsd     http://www.springframework.org/schema/aop     http://www.springframework.org/schema/aop/spring-aop-3.1.xsd">    <!-- 自动扫描 -->    <context:component-scan base-package="com.cn.wolf"/>    <!-- 引入配置文件 -->    <bean id="propertyConfigurer"          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="location" value="classpath:jdbc.properties"/>    </bean>    <!--数据源配置-->    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"          destroy-method="close">        <property name="driverClassName" value="${driver}"/>        <property name="url" value="${url}"/>        <property name="username" value="${username}"/>        <property name="password" value="${password}"/>        <!-- 初始化连接大小 -->        <property name="initialSize" value="${initialSize}"></property>        <!-- 连接池最大数量 -->        <property name="maxActive" value="${maxActive}"></property>        <!-- 连接池最大空闲 -->        <property name="maxIdle" value="${maxIdle}"></property>        <!-- 连接池最小空闲 -->        <property name="minIdle" value="${minIdle}"></property>        <!-- 获取连接最大等待时间 -->        <property name="maxWait" value="${maxWait}"></property>    </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"/>        <property  name="configLocation"  value="classpath:SqlMapConfig.xml"/>        <!-- 自动扫描mapping.xml文件 -->        <!--<property name="mapperLocations" value="classpath:com/cn/wolf/mapping/*.mapper.xml"></property>-->        <!--类的别名-->        <property name="typeAliasesPackage" value="com.cn.wolf.mapping"/>    </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.cn.wolf.dao"/>        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>    </bean>    <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">        <constructor-arg index="0" ref="sqlSessionFactory"/>        <!--以下是批处理配置,但是单个insert时返回是一个负值-2147482646-->        <!--<constructor-arg index="1" value="BATCH"/>-->    </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>    <tx:advice id="txAdvice" transaction-manager="transactionManager">        <tx:attributes>            <tx:method name="delete*" propagation="REQUIRED" read-only="false"                       rollback-for="java.lang.Exception" no-rollback-for="java.lang.RuntimeException"/>            <tx:method name="insert*" propagation="REQUIRED" read-only="false"                       rollback-for="java.lang.RuntimeException" />            <tx:method name="update*" propagation="REQUIRED" read-only="false"                       rollback-for="java.lang.Exception" />            <tx:method name="find*" propagation="SUPPORTS"/>            <tx:method name="get*" propagation="SUPPORTS"/>            <tx:method name="select*" propagation="SUPPORTS"/>        </tx:attributes>    </tx:advice>    <aop:config>        <aop:pointcut id="pc" expression="execution(* com.cn.wolf.service.*.*(..))" /> <!--把事务控制在Service层-->        <aop:advisor pointcut-ref="pc" advice-ref="txAdvice" />    </aop:config></beans>
有问题的spring-mvc.xml配置如下:
<?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:context="http://www.springframework.org/schema/context"   xmlns:mvc="http://www.springframework.org/schema/mvc"   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-4.0.xsd"><!-- 注解扫描包 --><context:component-scan base-package="com.cn.wolf" /><!-- 开启注解 --><mvc:annotation-driven /><!-- 静态资源的访问 --><mvc:resources location="/static/" mapping="/static/**" /><bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"></bean><bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"><property name="messageConverters"><list><bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" /></list></property></bean><!-- 定义视图解析器 --><bean id="viewResolver"class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="WEB-INF/jsp"></property><property name="contentType" value="text/html; charset=UTF-8" /><property name="suffix" value=".jsp"></property></bean><!-- 配置文件上传,如果没有使用文件上传可以不用配置,当然如果不配,那么配置文件中也不必引入上传组件包 --><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><!-- 默认编码 --><property name="defaultEncoding" value="utf-8" /><!-- 文件大小最大值 --><property name="maxUploadSize" value="10485760000" /><!-- 内存中的最大值 --><property name="maxInMemorySize" value="40960" /></bean></beans>
在service实现层有一个saveUser的方法如下:
    public int saveUser(User user){            userDao.saveUser(user);            userDao.saveUser(user);        return 1;    }
以上测试结果:第一个user保存成功,第二个user保存时主键冲突保存失败,但是第一个没有回滚(如果事务起作用会回滚的),为什么事务不起作用呢???经过许久的努力终于找到原因了(如果以下原因不对请不要喷!)。当加载spring-mvc.xml时,通过扫描com.cn.wolf包注入了一个没有事务的service,而pring的aop是在运行时拦截注入的,所以事务在此不起作用。
根据以上分析我最后对以上两个文件做了些许修改,问题就解决了,具体spring-mybatis.xml配置如下:
<?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:context="http://www.springframework.org/schema/context"       xmlns:aop="http://www.springframework.org/schema/aop"       xmlns:tx="http://www.springframework.org/schema/tx"       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/tx     http://www.springframework.org/schema/tx/spring-tx-3.1.xsd     http://www.springframework.org/schema/aop     http://www.springframework.org/schema/aop/spring-aop-3.1.xsd">    <!-- 自动扫描 -->    <context:component-scan base-package="com.cn.wolf.*">        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>    </context:component-scan>    <!-- 引入配置文件 -->    <bean id="propertyConfigurer"          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="location" value="classpath:jdbc.properties"/>    </bean>    <!--数据源配置-->    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">        <property name="driverClassName" value="${driver}"/>        <property name="url" value="${url}"/>        <property name="username" value="${username}"/>        <property name="password" value="${password}"/>        <!-- 初始化连接大小 -->        <property name="initialSize" value="${initialSize}"></property>        <!-- 连接池最大数量 -->        <property name="maxActive" value="${maxActive}"></property>        <!-- 连接池最大空闲 -->        <property name="maxIdle" value="${maxIdle}"></property>        <!-- 连接池最小空闲 -->        <property name="minIdle" value="${minIdle}"></property>        <!-- 获取连接最大等待时间 -->        <property name="maxWait" value="${maxWait}"></property>    </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"/>        <property  name="configLocation"  value="classpath:SqlMapConfig.xml"/>        <!-- 自动扫描mapping.xml文件 -->        <!--<property name="mapperLocations" value="classpath:com/cn/wolf/mapping/*.mapper.xml"></property>-->        <!--类的别名-->        <property name="typeAliasesPackage" value="com.cn.wolf.mapping"/>    </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.cn.wolf"/>        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>    </bean>    <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">    <!--<bean id="sqlSessionManager" class="org.apache.ibatis.session.SqlSessionManager">-->        <constructor-arg index="0" ref="sqlSessionFactory"/>        <!--以下是批处理配置,但是单个insert时返回是一个负值-2147482646-->        <!--<constructor-arg index="1" value="BATCH"/>-->    </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>    <!--使用注解事务-->    <!--<tx:annotation-driven transaction-manager="transactionManager" />-->    <tx:advice id="txAdvice" transaction-manager="transactionManager">        <!--<tx:attributes>            <tx:method name="delete*" propagation="REQUIRED" read-only="false"                       rollback-for="java.lang.Exception" no-rollback-for="java.lang.RuntimeException"/>            <tx:method name="insert*" propagation="REQUIRED" read-only="false"                       rollback-for="java.lang.Exception" />            <tx:method name="save*" propagation="REQUIRED" read-only="false"                       rollback-for="Throwable" />            <tx:method name="update*" propagation="REQUIRED" read-only="false"                       rollback-for="java.lang.Exception" />            <tx:method name="find*" propagation="SUPPORTS"/>            <tx:method name="get*" propagation="SUPPORTS"/>            <tx:method name="select*" propagation="SUPPORTS"/>        </tx:attributes>-->        <tx:attributes>            <tx:method name="*" propagation="REQUIRED" rollback-for="Throwable"/>        </tx:attributes>    </tx:advice>    <aop:config>        <aop:pointcut id="pc" expression="execution(* com.cn.wolf.service.*.*(..))" /> <!--把事务控制在Service层-->        <aop:advisor pointcut-ref="pc" advice-ref="txAdvice" />    </aop:config></beans>
pring-mvc.xml配置如下:
<?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:context="http://www.springframework.org/schema/context"   xmlns:mvc="http://www.springframework.org/schema/mvc"   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-4.0.xsd"><!-- 开启注解 --><!--<mvc:annotation-driven />--><context:annotation-config /><!-- 设置使用注解的类所在的jar包,这里必须排除扫描service层的组件 --><context:component-scan base-package="com.cn.wolf.*"><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/></context:component-scan><!-- 静态资源的访问 --><mvc:resources location="/static/" mapping="/static/**" /><bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"></bean><bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"><property name="messageConverters"><list><bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" /></list></property></bean><!-- 定义视图解析器 --><bean id="viewResolver"class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/jsp"></property><property name="contentType" value="text/html; charset=UTF-8" /><property name="suffix" value=".jsp"></property></bean><!-- 配置文件上传,如果没有使用文件上传可以不用配置,当然如果不配,那么配置文件中也不必引入上传组件包 --><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><!-- 默认编码 --><property name="defaultEncoding" value="utf-8" /><!-- 文件大小最大值 --><property name="maxUploadSize" value="10485760000" /><!-- 内存中的最大值 --><property name="maxInMemorySize" value="40960" /></bean></beans>
OK了,我的事务问题解决了,如果对你有用就带走,如果没有用别喷哈。
