ibatis的批处理

(1)spring模式:尽管spring已经配置了事务,但以下代码中还是要设置事务,不然batch不会起作用;另外这里虽然设了一下事务处理,但对全局事务并不会造成影响;
注:不启用事务将建立多次连接,这表示batch没起作用,建立事务后一次连接就搞定了.

Java代码  

1. public void batchAddExamlog(List examlogList) throws SQLException{                   
2.     SqlMapClient smc=this.getSqlMapClient();                                           
3.     try {                                                                              
4.         smc.startTransaction();                                                          
5.         smc.startBatch();                                                                
6.                                                                                                                                                          
7.         for (Iterator iter = examlogList.iterator(); iter.hasNext();) {  
8.             Examlog log = (Examlog) iter.next();  
9.             smc.update("insertExamlog", log);  
10.         }                                                                              
11.         smc.executeBatch();                                                              
12.     } catch (Exception e) {                                                            
13.         // TODO: handle exception                                                        
14.     }finally{                                                                          
15.         smc.commitTransaction();                                                         
16.         smc.endTransaction();                                                            
17.     }                                                                                  
18. }    

                                                                                 

(2)直接采用回调函数设置                                                                             

Java代码  

1. public void batchAddExamlog2(List examlogList){                                      
2.     getSqlMapClientTemplate().execute(new SqlMapClientCallback() {                     
3.         public Object doInSqlMapClient(SqlMapExecutor executor) throws SQLException {  
4.          executor.startBatch();                                                        
5.          executor.update("insertSomething", "myParamValue");                           
6.          executor.update("insertSomethingElse", "myOtherParamValue");                  
7.          executor.executeBatch();                                                      
8.          return null;                                                                  
9.         }                                                                              
10.     });                                                                              
11. }
