ibatis2.34 获取oracle的Date是无法获取时间的问题
oracle驱动中的getDate只返回日期，没有时间，而getTimestamp返回日期和时间。
由于特殊原因，我不是根据字段类型来获取值，而是以Object方式获取字段值，结果是取不到时间，研究ibatis源码，发现DateTypeHandler.java中已经做了转换，使用getTimestamp获取值再转成Date，但是ObjectTypeHandler却没做转换，而程序却是调用ObjectTypeHandler，所以出现取不到时间的问题，于是修改ObjectTypeHandler源码，增加
public Object getResult(ResultSet rs, String columnName)throws SQLException{Object object = rs.getObject(columnName);if (rs.wasNull()){return null;}else{boolean b = object instanceof java.sql.Date;if (b)object = new Date(rs.getTimestamp(columnName).getTime());return object;}}public Object getResult(ResultSet rs, int columnIndex) throws SQLException{Object object = rs.getObject(columnIndex);if (rs.wasNull()){return null;}else{boolean b = object instanceof java.sql.Date;if (b)object = new Date(rs.getTimestamp(columnIndex).getTime());return object;}}public Object getResult(CallableStatement cs, int columnIndex)throws SQLException{Object object = cs.getObject(columnIndex);if (cs.wasNull()){return null;}else{boolean b = object instanceof java.sql.Date;if (b)object = new Date(cs.getTimestamp(columnIndex).getTime());return object;}}
