编辑员工功能开发

1. 需求分析

首先需要完成根据员工id查询员工的功能,使员工的原始数据正常渲染

其次要完成编辑员工功能,根据PUT请求发送的数据进行更新操作

2. 代码开发

controller层:

@GetMapping("/{id}")
    @ApiOperation(value = "根据id查询员工")
    public Result<Employee> getById(@PathVariable Long id){
        log.info("查询id为{}的员工",id);
        Employee employee = employeeService.getById(id);
        return Result.success(employee);
    }

    @PutMapping
    @ApiOperation(value = "编辑员工")
    public Result editEmp(@RequestBody EmployeeDTO employeeDTO){
        log.info("编辑员工: {}",employeeDTO);
        employeeService.editEmp(employeeDTO);
        return Result.success();
    }

service层:

@Override
    public void editEmp(EmployeeDTO employeeDTO) {
        //创建新的员工对象
        Employee employee = new Employee();

        //将DTO中的属性复制到员工对象
        BeanUtils.copyProperties(employeeDTO,employee);

        //设置更新人
        employee.setUpdateUser(BaseContext.getCurrentId());

        //设置更新时间为now
        employee.setUpdateTime(LocalDateTime.now());

        //调用mapper层接口更新员工信息
        employeeMapper.update(employee);
    }

    @Override
    public Employee getById(Long id) {
        Employee employee = employeeMapper.getById(id);
        return employee;
    }

mapper层:

查询员工:

@Select("select * from employee where id = #{id}")
    Employee getById(Long id);

更新操作:

<update id="update">
        update employee
        <set>
            <if test="name != null and name != ''">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="updateTime != null">update_time = #{updateTime},</if>
            <if test="idNumber != null">id_number = #{idNumber},</if>
            <if test="updateUser != null">update_user = #{updateUser},</if>
            <if test="status != null">status = #{status}</if>
        </set>
        where id = #{id}
    </update>
