一.需求分析

課程營銷信息包括課程價格、課程有效期等信息。

二.數據模型

課程營銷信息使用course_market表存儲。
數據模型如下：
文件位置：xcEduService01\xc-framework-model\src\main\java\com\xuecheng\framework\domain\course\CourseMarket.java

package com.xuecheng.framework.domain.course;import lombok.Data; import lombok.ToString; import org.hibernate.annotations.GenericGenerator;import javax.persistence.*; import java.io.Serializable; import java.util.Date;@Data @ToString @Entity @Table(name="course_market") @GenericGenerator(name = "jpa-assigned", strategy = "assigned") public class CourseMarket implements Serializable {private static final long serialVersionUID = -916357110051689486L;@Id@GeneratedValue(generator = "jpa-assigned")@Column(length = 32)private String id;private String charge;private String valid;private String qq;private Float price;private Float price_old; // private Date expires;@Column(name = "start_time")private Date startTime;@Column(name = "end_time")private Date endTime;}

三.服務端

1.Api接口

文件位置：xcEduService01\xc-service-api\src\main\java\com\xuecheng\api\course\CourseControllerApi.java

1）查詢課程營銷信息

@ApiOperation("獲取課程營銷信息") public CourseMarket getCourseMarketById(String courseId);

2）更新課程營銷信息

@ApiOperation("更新課程營銷信息") public ResponseResult updateCourseMarket(String id,CourseMarket courseMarket);

2.Dao

文件位置：xcEduService01\xc-service-manage-course\src\main\java\com\xuecheng\manage_course\dao\CourseMarketRepository.java

public interface CourseMarketRepository extends JpaRepository<CourseMarket, String> { }

3.Service

文件位置：xcEduService01\xc-service-manage-course\src\main\java\com\xuecheng\manage_course\service\CourseService.java

public CourseMarket getCourseMarketById(String courseid) {Optional<CourseMarket> optional = courseMarketRepository.findById(courseId);if(!optional.isPresent()){return optional.get();} return null; }@public CourseMarket updateCourseMarket(String id, CourseMarket courseMarket) {CourseMarket one = this.getCourseMarketById(id);if(one!=null){one.setCharge(courseMarket.getCharge());one.setStartTime(courseMarket.getStartTime());//課程有效期，開始時間one.setEndTime(courseMarket.getEndTime());//課程有效期，結束時間one.setPrice(courseMarket.getPrice());one.setQq(courseMarket.getQq());one.setValid(courseMarket.getValid());courseMarketRepository.save(one);}else{//添加課程營銷信息one = new CourseMarket();BeanUtils.copyProperties(courseMarket, one);//設置課程idone.setId(id);courseMarketRepository.save(one);} return one; }

4.Controller

文件位置：xcEduService01\xc-service-manage-course\src\main\java\com\xuecheng\manage_course\controller\CourseController.java

@Override @PostMapping("/coursemarket/update/{id}") public ResponseResult updateCourseMarket(@PathVariable("id") String id, @RequestBody CourseMarket courseMarket) {CourseMarket courseMarket_u = courseService.updateCourseMarket(id, courseMarket);if(courseMarket_u!=null){return new ResponseResult(CommonCode.SUCCESS);}else{return new ResponseResult(CommonCode.FAIL);} } @Override @GetMapping("/coursemarket/get/{courseId}") public CourseMarket getCourseMarketById(@PathVariable("courseId") String courseId) {return courseService.getCourseMarketById(courseId); }

四.前端

1.Api 方法

文件位置：xc-ui-pc-teach\src\module\course\api\course.js

//獲取課程營銷信息 export const getCourseMarketById = id => {return http.requestQuickGet(apiUrl+'/course/coursemarket/get/'+id) } // 更新課程營銷信息 export const updateCourseMarket =(id,courseMarket) => {return http.requestPost(apiUrl+'/course/coursemarket/update/'+id,courseMarket) }

2.編寫 course_marketinfo.vue

文件位置：xc-ui-pc-teach\src\module\course\page\course_manage\course_marketinfo.vue

1）template

<template><div><el-form :model="courseForm" label-width="80px" :rules="courseRules" ref="courseForm"><el-form-item label="課程名稱" prop="name"><el-input v-model="courseForm.name" auto-complete="off" ></el-input></el-form-item><el-form-item label="適用人群" prop="users"><el-input type="textarea" v-model="courseForm.users" auto-complete="off" ></el-input></el-form-item><el-form-item label="課程分類" prop="categoryActive"><el-cascaderexpand-trigger="hover":options="categoryList"v-model="categoryActive":props="props"></el-cascader></el-form-item><el-form-item label="課程等級" prop="grade"><b v-for="grade in gradeList"><el-radio v-model="courseForm.grade" :label="grade.sdId" >{{grade.sdName}}</el-radio>&nbsp;&nbsp;</b></el-form-item><el-form-item label="學習模式" prop="studymodel"><b v-for="studymodel_v in studymodelList"><el-radio v-model="courseForm.studymodel" :label="studymodel_v.sdId" >{{studymodel_v.sdName}}</el-radio>&nbsp;&nbsp;</b></el-form-item><el-form-item label="課程介紹" prop="description"><el-input type="textarea" v-model="courseForm.description" ></el-input></el-form-item></el-form><div slot="footer" class="dialog-footer"><el-button type="primary" @click.native="save" :loading="editLoading">提交</el-button></div></div> </template>

2）數據對象

data() {return {dotype:'',courseid:'',studymodelList:[],gradeList:[],editLoading: false,props: {value: 'id',label:'label',children:'children'},categoryList: [],categoryActive:[],courseForm: {id:'',name: '',users: '',grade:'',studymodel:'',mt:'',st:'',description: ''},courseRules: {name: [{required: true, message: '請輸入課程名稱', trigger: 'blur'}],category: [{required: true, message: '請選擇課程分類', trigger: 'blur'}],grade: [{required: true, message: '請選擇課程等級', trigger: 'blur'}],studymodel: [{required: true, message: '請選擇學習模式', trigger: 'blur'}]}}},

3）保存方法

methods: {save () {//修改課程this.$refs.courseForm.validate((valid) => {if (valid) {this.$confirm('確認提交嗎？', '提示', {}).then(() => {this.editLoading = true;let mt = this.categoryActive[0];let st = this.categoryActive[1];this.courseForm.mt = mt;this.courseForm.st = st;let id = this.courseForm.idcourseApi.updateCoursebase(id,this.courseForm).then((res) => {this.editLoading = false;if(res.success){this.$message({message: '提交成功',type: 'success'});}else{if(res.message){this.$message.error(res.message);}else{this.$message.error('提交失敗');}}});});}});}},

4）在mounted鉤子方法中查詢課程營銷信息及數據字典信息

mounted(){//查詢數據字典字典systemApi.sys_getDictionary('201').then((res) => { // console.log(res);this.studymodelList = res.dvalue;});systemApi.sys_getDictionary('200').then((res) => {this.gradeList = res.dvalue;});//取課程分類courseApi.category_findlist({}).then((res) => {this.categoryList = res.children;});//查詢課程信息//課程idthis.courseid = this.$route.params.courseid;courseApi.getCoursebaseById(this.courseid).then((res) => { // console.log(res);this.courseForm = res;//課程分類顯示，需要兩級分類this.categoryActive.push(this.courseForm.mt);this.categoryActive.push(this.courseForm.st);});}
