Spring+Vue修改功能

后端

数据回显，根据ID回显

 @GetMapping("/findById/{id}")
    public Users findById(@PathVariable("id") Integer id){
        return usersRepository.findById(id).get();
    }

修改数据，根据回显的数据回显

  @PutMapping("/update")
    public String update(@RequestBody Users users){
        Users result = usersRepository.save(users);
        if (result!= null){
            return "success";
        }else {
            return "SB, this is error";
        }
    }

前端

写一个路由，支持修改跳转

import UserUpdate from "../views/UserUpdate.vue";


    {
        path: '/userUpate',
        component: UserUpdate
    }

UserUpdate.vue

<template>
    <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
        <el-form-item label="ID">
            <el-input v-model="ruleForm.id" readOnly></el-input>
        </el-form-item>
        <el-form-item label="名称" prop="name">
