事务超时不能用于与oracle的休眠

问题描述

我有问题为oracle上的hibernate设置事务超时。它不起作用。任何人都可以帮忙吗？
SaveOrUpdate在规定的10秒内不会返回。它会挂起很长时间。
我正在使用Oracle 10r2。

Hibernate配置文件

 <冬眠-结构> 
< session-factory> 
< property name =connection.driver_class> oracle.jdbc.driver.OracleDriver< / property> 
< property name =connection.url> jdbc：oracle：thin：@ 9.9.9.9：1521：orcl< / property> 
< property name =connection.username> foouser< / property> 
< property name =connection.password> foopass< / property> 
< property name =hibernate.c3p0.min_size> 5< / property> 
< property name =hibernate.c3p0.max_size> 20< / property> 
< property name =dialect> org.hibernate.dialect.Oracle9Dialect< / property> 
< property name =current_session_context_class>线程< / property> 
 < property name =cache.provider_class> org.hibernate.cache.NoCacheProvider< / property> 
 < property name =show_sql> false< / property> 
 < mapping resource =foo.hbm.xml/> 
< / session-factory> 
< / hibernate-configuration> 
  

Hibernate class

  public class foo implements Serializable 
 {
 ... 
 public void save（）throws Exception 
 {
 Session dbSession = null; 
交易tran = null; 
 try 
 {
 dbSession = PersistenceMgr.getPersistenceMgr（）。getDbSession（）; 
 tran = dbSession.beginTransaction（）; 
 tran.setTimeout（10）; // 10秒
 dbSession.saveOrUpdate（this）; 
 tran.commit（）; 
 
 catch（HibernateException e）
 {
 if（tran！= null）
 {
 try {tran.rollback（）;} 
 $ catch（HibernateException he）{} 
} 
 ... 
} 
 finally 
 {
 if（dbSession！= null）
 {
 try {dbSession.close（）;} 
 catch（HibernateException e）{} 
} 
} 
} 
 
} 
  

解决方案

在事务启动之前需要设置超时。

而不是

  tran = dbSession.beginTransaction（）; 
 tran.setTimeout（10）; // 10秒
  

try

  tran = dbSession.getTransaction（）; 
 tran.setTimeout（10）; 
 tran.begin（）; 
  

I am having problem setting the transaction timeout for hibernate on oracle. It does not work.Can anyone help?The "SaveOrUpdate" will not return within the stated 10 seconds. It will hang for a very long time.I am using Oracle 10r2.

Hibernate Configuration File

<hibernate-configuration>
<session-factory>
    <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
    <property name="connection.url">jdbc:oracle:thin:@9.9.9.9:1521:orcl</property>

    <property name="hibernate.c3p0.max_size">20</property>
    <property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>
    <property name="current_session_context_class">thread</property>
    <!-- Disable the second-level cache  -->
    <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
    <!-- Echo all executed SQL to stdout -->
    <property name="show_sql">false</property>
    <!-- Mapping files -->
    <mapping resource="foo.hbm.xml"/>
</session-factory>
</hibernate-configuration>

Hibernate class

public class foo implements Serializable
{
...
    public void save() throws Exception
    {
        Session     dbSession = null;
        Transaction tran      = null;
        try
        {
            dbSession = PersistenceMgr.getPersistenceMgr().getDbSession();
            tran      = dbSession.beginTransaction();
            tran.setTimeout(10); // 10 seconds
            dbSession.saveOrUpdate(this);
            tran.commit();
        }
        catch (HibernateException e)
        {
            if(tran!=null)
            {
                try{tran.rollback();}
                catch(HibernateException he){}
            }
            ...
        }
        finally
        {
            if( dbSession != null )
            {
                try{dbSession.close();}
                catch(HibernateException e){}
            }
        }
    }

}

解决方案

The timeout needs to be set before the transaction is started.

instead of

tran = dbSession.beginTransaction();
tran.setTimeout(10);// 10 seconds

try

tran = dbSession.getTransaction();
tran.setTimeout(10);
tran.begin();
