系统管理实现
修改密码实现
前端 modifyPassword.vue：
<template><el-card><el-formref="formRef":model="form":rules="rules"label-width="150px"><el-form-item label="用户名：" prop="userName"><el-input v-model="form.userName" disabled/></el-form-item><el-form-item label="原密码：" prop="oldPassword"><el-input v-model="form.oldPassword" type="password"/></el-form-item><el-form-item label="新密码：" prop="newPassword"><el-input v-model="form.newPassword" type="password"/></el-form-item><el-form-item label="确认新密码：" prop="newPassword2"><el-input v-model="form.newPassword2" type="password"/></el-form-item><el-form-item><el-button type="primary" @click="onSubmit">确认修改</el-button></el-form-item></el-form></el-card>
</template><script setup>
import { ref } from 'vue'
import axios from "@/util/axios";
import { ElMessage } from "element-plus";const form=ref({userName:"",password:"",oldPassword:"",newPassword:"",newPassword2:""
})const rules=ref({userName: [{required: true,message: '请输入用户名'}],oldPassword: [{required: true,message: '请输入密码'}],newPassword: [{required: true,message: '请输入新密码'}],newPassword2: [{required: true,message: '请输入确认新密码'}],})const formRef=ref(null);const initFormData=()=>{let userInfoJson=window.sessionStorage.getItem("userInfo");form.value=JSON.parse(userInfoJson);
}initFormData()const onSubmit=()=>{formRef.value.validate(async(valid)=>{if(valid){console.log("success")if(form.value.oldPassword!==form.value.password){ElMessage.error("原密码错误！");}else if(form.value.newPassword!==form.value.newPassword2){ElMessage.error("确认新密码错误！");}else{try{let result=await axios.post("admin/modifyPassword",form.value)let data=result.data;if(data.code==0){ElMessage.success("密码修改成功，重新登录后生效！");formRef.value.resetFields();}else{ElMessage.error(data.msg);}}catch(err){console.log(err)ElMessage.error("系统运行出错，请联系管理员！");}}}else{console.log("fail")return false}})
}</script><style lang="scss" scoped>.el-input{width: 300px;
}
</style>
后端：AdminController
/*** 修改密码* @param admin* @return*/@PostMapping("/admin/modifyPassword")public R modifyPassword(@RequestBody Admin admin){if(StringUtil.isEmpty(admin.getUserName())){return R.error("用户名不能为空！");}if(StringUtil.isEmpty(admin.getNewPassword())){return R.error("新密码不能为空！");}adminService.update(new UpdateWrapper<Admin>().set("password",admin.getNewPassword()).eq("userName",admin.getUserName()));return R.ok();}router.js
