一、后端

1、CourseService​

根据讲师id查询讲师所讲课程列表

接口

List<Course> selectByTeacherId(String teacherId);

实现

/**
     * 根据讲师id查询当前讲师的课程列表
     * @param teacherId
     * @return
     */
@Override
public List<Course> selectByTeacherId(String teacherId) {

    QueryWrapper<Course> queryWrapper = new QueryWrapper<Course>();

    queryWrapper.eq("teacher_id", teacherId);
    //按照最后更新时间倒序排列
    queryWrapper.orderByDesc("gmt_modified");

    List<Course> courses = baseMapper.selectList(queryWrapper);
    return courses;
}

2、TeacherController​

@Autowired
private CourseService courseService;

修改getById方法：

@ApiOperation(value = "根据ID查询讲师")
@GetMapping(value = "{id}")
public R getById(
        @ApiParam(name = "id", value = "讲师ID", required = true)
        @PathVariable String id){

    //查询讲师信息
    Teacher teacher = teacherService.getById(id);

    //根据讲师id查询这个讲师的课程列表
    List<Course> courseList = courseService.selectByTeacherId(id);

    return R.ok().data("teacher", teacher).data("courseList", courseList);
}

3、swagger测试​

二、前端详情js

1、teacher api​

api/teacher.js

getById(teacherId) {
    return request({
        url: `${api_name}/${teacherId}`,
        method: 'get'
    })
}

2、讲师详情页中调用api​

pages/teacher/_id.vue

<script>
import teacher from "@/api/teacher"
export default {
  asyncData({ params, error }) {
    return teacher.getById(params.id).then(response => {
      console.log(response);
      return { 
        teacher: response.data.data.teacher,
        courseList: response.data.data.courseList
      }
    })
  }
}
</script>

三、页面渲染

1、讲师基本信息模板​

<template>
  <div id="aCoursesList" class="bg-fa of">
    <!-- 讲师介绍 开始 -->
    <section class="container">
      <header class="comm-title">
        <h2 class="fl tac">
          <span class="c-333">讲师介绍</span>
        </h2>
      </header>
      <div class="t-infor-wrap">
        <!-- 讲师基本信息 开始 -->

        <!-- /讲师基本信息 结束 -->
        <div class="clear"/>
      </div>
      <section class="mt30">
        <div>
          <header class="comm-title all-teacher-title c-course-content">
            <h2 class="fl tac">
              <span class="c-333">主讲课程</span>
            </h2>
            <section class="c-tab-title">
              <a href="javascript: void(0)">&nbsp;</a>
            </section>
          </header>
          <!-- 无数据提示 开始-->

          <!-- /无数据提示 结束-->

          <!-- 课程列表 开始-->

          <!-- /课程列表 结束-->
        </div>
      </section>
    </section>
    <!-- /讲师介绍 结束 -->
  </div>
</template>

2、讲师详情显示​

<!-- 讲师基本信息 开始 -->
<section class="fl t-infor-box c-desc-content">
    <div class="mt20 ml20">
        <section class="t-infor-pic">
            <img :src="teacher.avatar" :alt="teacher.name">
        </section>
        <h3 class="hLh30">
            <span class="fsize24 c-333">{{ teacher.name }}
                &nbsp;
                {{ teacher.level===1?'高级讲师':'首席讲师' }}
            </span>
        </h3>
        <section class="mt10">
            <span class="t-tag-bg">{{ teacher.intro }}</span>
        </section>
        <section class="t-infor-txt">
            <p class="mt20">{{ teacher.career }}</p>
        </section>
        <div class="clear"/>
    </div>
</section>
<!-- /讲师基本信息 结束 -->

3、无数据提示​

<!-- 无数据提示 开始-->
<section class="no-data-wrap" v-if="courseList.total==0">
    <em class="icon30 no-data-ico">&nbsp;</em>
    <span class="c-666 fsize14 ml10 vam">没有相关数据，小编正在努力整理中...</span>
</section>
