spring+ibais批量处理问题

[winnyboy]

ibatis批量处理有问题, 每次都是走到输入"aaaaaaaaaaaaaa"后就不行了.
没有出错提示, 就这个这提示: PROPAGATION_REQUIRED,ISOLATION_DEFAULT,-Exception
for循环可以走完. 就是不会执行任何操作. 大家看看这是什么问题??
大家看我下面的代码:

public void updateBatchFolderNum(final List<Map<String,Object>> list) {
		if (list == null) return;
		System.out.println("dao size ==" + list.size());
		
	    this.getSqlMapClientTemplate().execute(new SqlMapClientCallback(){ 
	    public Object doInSqlMapClient(SqlMapExecutor executor) 
	            throws SQLException { 
	    executor.startBatch(); 
	    int batch = 0; 
	    for(Map<String,Object> p:list){ 
	    	System.out.println("aaaaaaaaaaaaaa " );
		    executor.update("FFRelationSpace.updateSelf", p); 
		    batch++; 

		    if(batch==50){ 
		    	System.out.println("bbbbbbbbbbbbbbbbbbbb " );
		    	executor.executeBatch();
		    	System.out.println("cccccccccccccccccc" );
		    	batch = 0; 
		    } 
	    } 
	    executor.executeBatch(); 
	    return null; 
	    } 
	    }); 
	}
