接口相关信息

 controller层

    /*
    * 启用禁用员工账号
    * */
    @PostMapping("/status/{status}")
    @ApiOperation("启用禁用员工账号")
    public Result startOrStop(@PathVariable Integer status, Long id) {
        log.info("启用禁用员工{}，{}",status,id);
        employeeService.startOrStop(status,id);
        return Result.success();
    }

service和serviceimpl层 

 

    /*
    *启用禁用员工账号
    * */
    void startOrStop(Integer status, Long id);

    /*
    * 启用禁用员工账号
    * */
    @Override
    public void startOrStop(Integer status, Long id) {
        Employee employee=new Employee();
        employee.setStatus(status);
        employee.setId(id);
        employeeMapper.update(employee);
    }

 mapper层和xml配置文件

因为sql比较复杂所以使用在XML文件下配置动态SQL的方式实现功能

    void update(Employee employee);

 

    <!--更新员工信息-->
    <update id="update" parameterType="Employee">
        update employee
            /*前面是employee的属性*/
        <set>
            <if test="name != null"> name = #{name},</if>
            <if test="username != null"> username = #{username},</if>
            <if test="password != null">password = #{password},</if>
            <if test="phone != null"> phone = #{phone}, </if>
            <if test="sex != null"> sex = #{sex},</if>
            <if test="idNumber != null"> id_number = #{idNumber},</if>
            <if test="updateTime != null">update_Time = #{updateTime},</if>
            <if test="updateUser != null">update_User = #{updateUser},</if>
            /*因为用了set标签所以最后这里也加,*/
            <if test="status != null">status = #{status},</if>
        </set>
        where id=#{id}
    </update>
