1、使用實體類物件包裝引數：

/* seviceImpl層 */
public List<SysDept> getFaculty() {
        SysDept dept = new SysDept();
        dept.setDeptType(2);
        dept.setStatus("0");
        return deptMapper.selectDeptList(dept);
    }

/*.xml層對應 */

<select id="selectDeptList" parameterType="SysDept" resultMap="SysDeptResult">
<include refid="selectDeptVo"/>
   where d.del_flag = '0'
<if test="status != null and status != ''">
      AND status = #{status}
</if>
<if test="deptType != null and deptType != 0 ">
      AND dept_type = #{deptType}
</if>
</select>
 

2、使用@Param註解

/* mapper層對應介面 */
List<SysDept> queryDeptForMajorOrGrade(@Param("deptId") Long deptId, @Param("deptType") String deptType);

/* .xml層對應 (不用寫引數型別 parameterType的值 )*/

<select id="queryDeptForMajorOrGrade" resultMap="SysDeptResult">
   select d.dept_id, d.dept_name from sys_dept d where d.del_flag = '0' and d.status = '0' and find_in_set(#{deptId}, ancestors) and dept_type = #{deptType}
</select>
