Io 异常: The Network Adapter could not establish the connection (1)

在最近的项目中碰到一个问题就是我在执行Junit时候，后台报如下的错误： 

org.springframework.jdbc.UncategorizedSQLException: SqlMapClient operation; uncategorized SQLException for SQL []; SQL state [null]; error code [17002];   
--- The error occurred in com/huawei/support/poapply/orm/poApply.xml.  
--- The error occurred while executing update.  
--- Check the  INSERT INTO SUP_USER_LOGIN_LOG  (USERID,  LOGINTIME, ACCOUNT_TYPE, LOGIN_IP  ) VALUES (?, ?, ?, ? )             .  
--- Check the SQL Statement (preparation failed).  
--- Cause: java.sql.SQLException: Io 异常: The Network Adapter could not establish the connection; nested exception is com.ibatis.common.jdbc.exception.NestedSQLException:   
--- The error occurred in com/huawei/support/poapply/orm/poApply.xml.  
--- The error occurred while executing update.  
--- Check the INSERT INTO SUP_USER_LOGIN_LOG           (USERID,LOGINTIME, ACCOUNT_TYPE, LOGIN_IP ) VALUES (?,?,?,?)             .  
--- Check the SQL Statement (preparation failed).  
--- Cause: java.sql.SQLException: Io 异常: The Network Adapter could not establish the connection

当看到了<The error occurred while executing update. --- Check the SQL Statement (preparation failed). 如是想到是不是SQL的问题，如是琢磨着到了Ibatis的配置文件中检查。发现我的SQL语句是不存在问题的(单独的拿出来发到PL-SQL中执行的时候是OK的)，SQL如下：

	<!-- 向 登录日志表SUP_USER_LOGIN_LOG中插入数据 -->
	<!--Update by **_R09559/ for story_num on date  begin->
