跟踪到 at com.tydic.vop.complaint.service.CplntWorkorderService.feedBackComplaint(CplntWorkorderService.java:322) －》

CplntWorkorderService.java 内的 feedBackComplaint方法（322行）－》

322行： todoTaskDao.delete(todoTasks.get(0));

进入delete方法内部，

AbstractDaoSupport.java ->

publicvoid delete(To) {

daoHelper.delete(o, getHibernateTemplate());

public class HibernateDaoHelper {

/**

* 删除对象

public void delete(Object o, HibernateTemplatehibernateTemplate) {

hibernateTemplate.getSessionFactory().getCurrentSession().setFlushMode(FlushMode.AUTO);

hibernateTemplate.delete(o);

hibernateTemplate.getSessionFactory().getCurrentSession().flush();

}

执行delete 怎么报

2016-03-25 17:08:48,232 (JDBCExceptionReporter.java:101) ERROR - ORA-14400: inserted partition key does not map to any partition
这样的错误？？

推测：

1. delete 的 where 条件没有对应分区，可能会报找不到分区异常。

2. 对delete 进行代理？切面编程？进行额外的对数据库操作导致找不到分区异常。

观察执行delete的对象与 delete表： todo_task

2016-03-25 17:08:48,141 (CplntWorkorderService.java:321) INFO - todoTasks.get(0).getUpdTime(): 2016-03-24 21:45:21.0

分区条件 2016-03-24 21:45:21.0 && 表todo_task分区到 2017年，足够

排除1.

2.spring_applicationContext.xml

<beanid="vopSessionFactory"

<propertyname="eventListeners">

<map>

<entry>

<key>

<value>post-delete</value>

</key>

<refbean="deleteListener"/>

</entry>

...

<beanid="deleteListener"class="com.tydic.hbm.listener.DeleteEventListener"/>

<beanid="updateListener"class="com.tydic.hbm.listener.UpdateEventListener"/>

<beanid="saveListener"class="com.tydic.hbm.listener.SaveEventListener"/>

<beanid="collectionUpdListener"class="com.tydic.hbm.listener.UpdateCollectionEventListner"/>

进入 DeleteEventListener.java

publicvoid onPostDelete(PostDeleteEventevent) {

...

savePostDelLog(t.getName(), getAccessRecordId(id),chgValue);

...

跟进入 UlogCfgUtil.java

public class UlogCfgUtil {

private static final Log log = LogFactory.getLog(UlogCfgUtil.class);

private static ThreadLocal<String> loginId = new ThreadLocal<String>();

public void savePostDelLog(String tabName,StringupdDescribe,List<ValuePair>chgValues){

if(log.isDebugEnabled())log.debug("保存删除日志:" +tabName);

save("D",tabName,updDescribe,chgValues);

}

...

private void save(String oprType,String tabName,String recdId,List<ValuePair> chgValues){

log.info("begin 记录日志 about "+tabName);

DataSource ds = DbcpUtils.getVopLogDS();

Connection conn =null;

PreparedStatement stmt = null;

try{

conn = ds.getConnection();

conn.setAutoCommit(false);

stmt =conn.prepareStatement("insert into L_busi_table_log(L_busi_table_log_id,L_login_log_id,access_busi_table,access_record_id,table_opr_type,access_time)" +

" values(L_busi_table_log_idseq.nextval,?,?,?,?,sysdate)");

stmt.setString(1,loginId.get());

stmt.setString(2,tabName);

stmt.setString(3,recdId);

...

果然有额外插入日志 L_busi_table_log 查看分区，不够，建上

再次测试，还有那个报错！！

ERROR - ORA-14400: inserted partition key does not map to any partition

通过观察整个流程，

...

cplntWorkorderDao.saveComplaintFeedback(complaintFeedback);

...

发现有对多个表操作，

逐个检查所有表，发现表cplnt_Workorder 没分区，建上，

再测，

通过了？？！！！！

WHY ？？？？？

发现：

/**

* 删除对象

public void delete(Object o, HibernateTemplatehibernateTemplate) {

hibernateTemplate.getSessionFactory().getCurrentSession().setFlushMode(FlushMode.AUTO);

hibernateTemplate.delete(o);

hibernateTemplate.getSessionFactory().getCurrentSession().flush();

}

hibernateTemplate.getSessionFactory().getCurrentSession().flush();

？

这些数据库操作都在一个hibernate事务内，而前面的save 操作只是保存到 hibernate的缓存内，没有刷新到数据库，

而在这delete 时，flush 所有缓存，其中包含前面的save操作，导致 ORA-14400: inserted partition key does not map to any partition

查hibernate 缓存资料，确实如此。

缓存、刷新、flush

针对昨天同事遇到的hibernate的问题。算是hibernate最基本的东西。具了解，这个问题很多人遇到过，也很常见，却遇到了还经常会懵了。

为了加深印象，知其然，知其所以然。

之后单纯用原始的Hibernate框架做了一些验证，并且打开执行SQL打印输出台的，得出的结论：

前提是在同一事务中间：

1、利用sql语句， session.createSQLQuery(sql).executeUpdate();进行插入，输出台打印出sql插入语句；再利用sql语句，进行session.createSQLQuery(sql).uniqueResult(); 也会打印SQL查询语句，没有问题，可以查询到数据。

2、利用hibernate封装操作， session.save(entity); 进行插入，输出台并没有打印出插入的SQL语句，再利用 session.get(entity,id);方法做查询；也没有打印出SQL查询语句，但是是可以查询到数据的。到执行事务提交语句时，插入的SQL语句被打印出来

3、利用hibernate的session.save(entity); 进行插入，再利用《HQL》语句进行查询，效果同上面第二点。

4、利用hibernate的session.save(entity); 进行插入，输出台并没有打印出插入的SQL语句。再利用sql语句，进行session.createSQLQuery(sql).uniqueResult(); 会打印SQL查询语句。问题出现了，查询不到任何数据。这种情况下利用session.flush()方法，在查询之前执行到flush()方法，输出台会打印出插入的SQL语句。再进行查询就有数据。
