容器託管JPA + Spring + Tomcat的事務處理

Question

我想用JPA，Spring，hibernate和tomcat配置JOTM。我配置了某種方式，但它既不執行插入也不更新，換句話說，我無法在插入/更新數據後執行提交。我有以下配置。

％TOMCAT_HOME％/ CONF/context.xml中

<?xml version="1.0" encoding="utf-8"?> 
<Context> 
    <WatchedResource>WEB-INF/web.xml</WatchedResource> 
    <Resource name="jdbc/myDS" auth="Container" type="javax.sql.XADataSource" factory="org.objectweb.jotm.datasource.DataSourceFactory" driverClassName="com.mysql.jdbc.Driver" username="root" password="mypassword" url="jdbc:mysql://localhost:3306/myDB"/> 
    <Resource name="UserTransaction" auth="Container" type="javax.transaction.UserTransaction"/> 
    <Transaction factory="org.objectweb.jotm.UserTransactionFactory" jotm.timeout="60"/> 
</Context> 

JOTM 2.1.9 libaries在％TOMCAT提取％/ lib中

  Jotm-datasource.jar 
·   Jotm-core.jar 
·   Xapool.jar 
·   Log4j.jar

·   Howl.jar 

的src /主/ web應用/ META-INF/context.xml

<Context path="/MyJPATest" reloadable="true"> 
    <Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/> 
</Context> 

的src /主/ web應用/ WEB-INF /類/ carol.properties

PUserService的方法

@Transactional 
    public List<PUser> bootstrapUsers() 
    { 

     List<PUser> users = new ArrayList<PUser>(); 

     try 
     { 


      for (int i = 0; i < 5; i++) 
      { 

       PUser newUser = new PUser(); 
       newUser.setName("B_" + i); 
       PUser user = this.pUserRepository.save(newUser); 


       users.add(user); 

      } 

     } 
     catch (Exception e) 
     { 
      this.logger.error(e, e); 

      return null; 
     } 

     return users; 

    } 

的src /主/爪哇/ com.test.dao.PUserRepository（彈簧數據儲存庫）

public interface PUserRepository extends JpaRepository<PUser, Serializable> 
{ 

    PUser findByName(String username); 
} 

提前致謝。

由於您正在使用JTA，因此您的交易類型應該是transaction-type="JTA"在persistence.xml中。您可以在Configuration和bootstrapping下閱讀here。
