使用spring4 @Transactional和jdbctemplate时交易不起作用!!请帮帮我
application.xml中
<context:component-scan base-package="com.test" />
<bean id="txtManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<bean class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource"/>
</bean>
<tx:annotation-driven transaction-manager="txtManager" proxy-target-class="true"/>
java代码
package com.test;
@Component
public class TService {
@Autowired JdbcTemplate jdbcTemplate;
@Transactional(rollbackFor = Exception.class)
public void tt() throws Exception{
jdbcTemplate.update("insert into t_test values(1)");
jdbcTemplate.update("insert into t_test(dd) values(1)");
}
}
控制器代码
@Controller("")
public class Tcontroller {
@Autowired TService ts;
@RequestMapping(value = "/test", method = RequestMethod.GET)
public @ResponseBody Object all() throws Exception {
ts.tt();
return "";
}
}
tt()抛出异常,但是事务没有回滚!
今天,我发现了这个
[DEBUG] 23:36:19,729 org.springframework.aop.framework.CglibAopProxy (accept:833) - Unable to apply any optimisations to advised method: public void com.test.TService.tt() throws java.lang.Exception

如果事务遇到未经检查的运行时异常,则始终回滚该事务。您的问题可能是由于您捕获异常然后重新抛出它而引起的。做这样的事情是没必要的。
第16.5.3节:在其默认配置中,是Spring Framework的事务 基础结构代码仅标记用于回滚的事务 运行时,未经检查的异常;也就是抛出异常的时候 是RuntimeException的实例或子类。 (错误也会 - 默认情况下 - 导致回滚)。检查抛出的异常 从事务方法不会导致默认回滚 配置。
