springmvc + mybatise 一个service 处理处理多个mapper 事物不回滚


问题出现情况：

声明式事物@Transactional

在一个service调用了两个不同mapper 先后update两个数据,人为模拟后一个mapper异常，发现第一个mapper会提交数据。

网上有两种解决方法 第一个 方法 ，在@Transactional 调整事物传播方式从默认requared改为NESTED,并加入rollbackFor=Exception.class，修改后，无效。检查日志，发现当第一个mapper在执行完update时会按如下顺序执行：

DEBUG - Creating a new SqlSession

DEBUG - SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@d0d75] was not registered for synchronization because synchronization is not active

DEBUG - Fetching JDBC Connection from DataSource

DEBUG - JDBC Connection [jdbc:oracle:thin:@192.168.7.10:1521:VD, UserName=JOKER, Oracle JDBC driver] will not be managed by Spring

DEBUG - ooo Using Connection [jdbc:oracle:thin:@192.168.7.10:1521:VD, UserName=JOKER, Oracle JDBC driver]

DEBUG - ==>  Preparing: update ss_user s_user set s_user.certsn=?,s_user.deptno=?,s_user.userName=?,s_user.freeze=? where id=?

DEBUG - ==> Parameters: null, 1(String), 要12(String), true(Boolean), 01ed2b6bee29458a88c0d54b9ab3b63a(String)

DEBUG - Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@d0d75]

DEBUG - Returning JDBC Connection to DataSource

此时，已经Returning JDBC Connection to DataSource

再执行第二个mapper的update会报异常，但是没有回滚第一次操作。

网上第二个解决办法 原文来着这里：

主要意思是，因为web.xml中的设置，spring会默认加载bean*.xl中的容器作为父容器

 

 <context-param>

  <param-name>contextConfigLocation</param-name>

  <param-value>classpath:bean*.xml</param-value>

 </context-param>

 <servlet>

  <servlet-name>springmvc</servlet-name>

  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

  <init-param>

   <param-name>contextConfigLocation</param-name>

   <param-value>classpath:springmvc.xml</param-value>

  </init-param>

  <load-on-startup>1</load-on-startup>

 </servlet>

而在bean.xml中我设置了

<context:component-scan base-package="org.ezca.signsserver">

</context:component-scan>

父容器中的扫描到@trancction的bean是具有事物管理能力的，而springmvc.xml 中再次用到

<context:component-scan base-package="org.ezca" >

 </context:component-scan>

而此时，装配出来的bean是不具有事物管理能力的

，于是，子容器的bean将父容器的bean覆盖。

所以解决办法为在springmvc的扫描中加入：

 <context:component-scan base-package="org.ezca" >

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

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

 </context:component-scan>

将可能出现@tranction的bean过滤掉.

修改后运行效果如下：

第一个mapper

DEBUG - Creating a new SqlSession

DEBUG - Registering transaction synchronization for SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@101b455]

DEBUG - JDBC Connection [jdbc:oracle:thin:@192.168.7.10:1521:VD, UserName=JOKER, Oracle JDBC driver] will be managed by Spring

DEBUG - ==>  Preparing: update ss_user s_user set s_user.certsn=?,s_user.deptno=?,s_user.userName=?,s_user.freeze=? where id=?

DEBUG - ==> Parameters: null, 1(String), 要13(String), true(Boolean), 01ed2b6bee29458a88c0d54b9ab3b63a(String)

DEBUG - Releasing transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@101b455]

第二个mapper异常时:

EBUG - ooo Using Connection [jdbc:oracle:thin:@192.168.7.10:1521:VD, UserName=JOKER, Oracle JDBC driver]

DEBUG - ==>  Preparing: insert into ss_user_cert(id,alias,crlUrl,destory,encode,invalid,oid,publicKey,sn,subject,time,type,notBefore,notafter) values(?,'','http://www.ezca.org/crl/crl8.crl',?,?,?,?,?,?,?,?,1,?,?)

于是，回滚完成。
