我有一个这样的sql
<select id="getData" parameterType="map" resultMap="dataMapper">
SELECT name FROM TABLE
</select>
和这样的结果图
<resultMap id="dataMapper" type="String">
<result property="data" column="name" typeHandler="xxx.NameTypeHandler" />
</resultMap>
名称类型处理程序
public class NameTypeHandler implements TypeHandler<String> {
@Override
public void setParameter(PreparedStatement ps, int i, String parameter, JdbcType jdbcType) throws SQLException {
// TODO Auto-generated method stub
}
@Override
public String getResult(ResultSet rs, String columnName) throws SQLException {
return "test" + rs.getString(columnName);
}
@Override
public String getResult(ResultSet rs, int columnIndex) throws SQLException {
return "test" + rs.getString(columnIndex);
}
@Override
public String getResult(CallableStatement cs, int columnIndex) throws SQLException {
return "test" + cs.getString(columnIndex);
}
}
但它从不与处理程序一起使用
我可以这样使用吗?
