根据查询到详情，进行回想到弹窗，然后修改信息，保存更新用户信息

实现效果

代码实现

• controller代码

/**
     * 修改员工
     */
    @PutMapping
    public Result update(@RequestBody Emp emp) {
        log.info("修改员工操作 {}", emp);
        empService.update(emp);
        return Result.success();
    }

• mapper代码

    <!--更新员工-->
    <update id="update">
        update emp
        <set>
            <if test="username != null and username != ''">
                username = #{username},
            </if>
            <if test="password != null and password != ''">
                password = #{password},
            </if>
            <if test="name != null and name != ''">
                name = #{name},
            </if>
            <if test="gender != null">
                gender = #{gender},
            </if>
            <if test="image != null and image != ''">
                image = #{image},
            </if>
            <if test="job != null">
                job = #{job},
            </if>
            <if test="entrydate != null">
                entrydate = #{entrydate},
            </if>
            <if test="deptId != null">
                dept_id = #{deptId},
            </if>
            <if test="updateTime != null">
                update_time = #{updateTime},
            </if>
        </set>
        where id = #{id}
    </update>

• service代码

@Override
public void update(Emp emp) {
      emp.setUpdateTime(LocalDateTime.now());
      empMapper.update(emp);
}

需要更新下修改时间

这样我们就实现了，更新用户信息的操作
