ibatis 在给null值时报TypeException: Error setting null parameter解决方案

ibatis 在给null值时报TypeException: Error setting null parameter解决方案。

 

ibatis 在使用null值时，如下所示：

Map params = new HashMap(); params.put("XGBZ", "1"); params.put("BZ", "yz"); params.put("CSFL", null); params.put("GLBZ", null); params.put("TDATE",dd ); session.insert("ZHCS.insert", params);

 

以下是抛出的异常：

Most JDBC drivers require that the JdbcType must be specified for all nullable parameters.

解决方法 1：

Map params = new HashMap(); params.put("XGBZ", "1"); params.put("BZ", "yz"); params.put("CSFL", ""); params.put("GLBZ", "")); params.put("TDATE",dd ); session.insert("ZHCS.insert", params);

 

解决方法2：

更新jdbc驱动版本，如：ojdbc5.jar
