springboot @update含if test写法

@Update("<script> " +
            "UPDATE BD_ID_CARD_INFO SET " +
            "<if test='DRIVER_TYPE == \"主驾\" '> DRIVER_TYPE = '副驾',</if>" +
            "<if test='DRIVER_TYPE == \"副驾\" '> DRIVER_TYPE = '主驾',</if>" +
            "CAR_ID = #{0} where CAR_ID = #{0} " +
            "</script>")
	public void changeDriverType(String CAR_ID);

 "<if test='DRIVER_TYPE == \"主驾\" '> "

这个需要转义，如果==null,则不需要。
