Spring Jersey Mybatis Aop transaction事务失效解决方案SpringManagedTransaction will not be managed by Spring

整个项目的框架是Spring + Jersey + Mybatis， 事务是用Aop做的，不是用注解的形式，一直报这样的错误：

DEBUG: org.mybatis.spring.transaction.SpringManagedTransaction - JDBC Connection [ConnectionHandle{url=jdbc:postgresql://localhost/mypro, user=mypro, debugHandle=null, lastResetAgoInSec=92, lastUsedAgoInSec=92, creationTimeAgoInSec=92}] will not be managed by Spring

在网上找了很多方案，发现都没解决我的事务问题：

上面的资料都试过了，用注解的形式，单独跑过第一个项目是可以的，但是我现在是维护原来的项目，如果把以前的项目都改成注解的形式，工作量也是够大，所以还是要用Aop事务来处理，我的项目大致结构是：

service 接口

serviceImpl 接口实现类，实现接口，所有类上都加有@Servcie和@Path的注解

dao 接口

application.xml文件扫描所有的类

spring-mybatis.xml 数据源事务配置

<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(* com.xxxx.xx.service.*.*(..))" />

</aop:config>

刚开始配置文件是这样的，发现不管怎么试都不可以，还用

<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>

这个排除怀疑是service的重复扫描问题，还试了说是必须用@Component不能用@Service，来源：https://stackoverflow.com/questions/21104567/springjersey-transactional-annotation/24554236#24554236

但还是没有解决问题，还看来mybatis-spring的源码：

SpringManagedTransaction.java:

private void openConnection() throws SQLException {
this.connection = DataSourceUtils.getConnection(this.dataSource);
this.autoCommit = this.connection.getAutoCommit();
this.isConnectionTransactional = isConnectionTransactional(this.connection, this.dataSource);

if (this.logger.isDebugEnabled()) {
this.logger.debug(
"JDBC Connection ["
+ this.connection
+ "] will"
+ (this.isConnectionTransactional ? " " : " not ")
+ "be managed by Spring");
}
}

DataSourceUtils.java:

public static boolean isConnectionTransactional(Connection con, DataSource dataSource) {
if (dataSource == null) {
return false;
}
ConnectionHolder conHolder = (ConnectionHolder) TransactionSynchronizationManager.getResource(dataSource);
return (conHolder != null && connectionEquals(conHolder, con));
}

TransactionSynchronizationManager.java

public static Object getResource(Object key) {
Object actualKey = TransactionSynchronizationUtils.unwrapResourceIfNecessary(key);
Object value = doGetResource(actualKey);
if (value != null && logger.isTraceEnabled()) {
logger.trace("Retrieved value [" + value + "] for key [" + actualKey + "] bound to thread [" +
Thread.currentThread().getName() + "]");
}
return value;
}

发现通过Key,没有找到value

后来仔细看以前的配置文件，发现所有的事务都绑定在接口上了，我这里的事务要绑定在接口实现类上面，于是改成：

<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(* com.xxxx.xx.service.impl.*.*(..))" />

</aop:config>

测试之后发现，还是不行，按照上面的思路，另外单独试验一个项目，就是把所有serviceImpl的实现接口的接口继承关系去掉，就是只有实现类serviceImpl，尽然发现奇迹成功了，于是想到之前有接触过proxy-target-class这个属性，当时记不太清，就是接口或者类的代理吧，于是查看资料，发现：

proxy-target-class属性值决定是基于接口的还是基于类的代理被创建。首先说明下proxy-target-class=”true”和proxy-target-class=”false”的区别，为true则是基于类的代理将起作用（需要cglib库），为false或者省略这个属性，则标准的JDK 基于接口的代理将起作用，proxy-target-class在spring事务、aop、缓存这几块都有设置，其作用都是一样的

茅塞顿开，于是把配置文件改成：

<aop:config proxy-target-class="true">
<aop:advisor advice-ref="txAdvice" pointcut="execution(* com.xxxx.xx.service.impl.*.*(..))" />

</aop:config>

居然大功告成了，先总结到，会继续补齐解决方案！
