前台讲师显示

前台讲师列表显示

后端

controller提供分页接口
```java @RestController @CrossOrigin @RequestMapping(“/eduservice/front-teacher”) public class FrontTeacherController {

@Autowired private EduTeacherService eduTeacherService;

@Autowired private EduCourseService eduCourseService;

@GetMapping(“pageTeacher/{currentPage}/{limit}”) public ResultEntity pageTeacher(@PathVariable long currentPage, @PathVariable long limit) {
```
 // 此时没有使用element-ui提供的分页组件，返回的参数与后台不一致
 Map<String, Object> map = eduTeacherService.getPageFrontTeacher(currentPage, limit);
 return ResultEntity.ok().data(map);
```
}

}


-  service实现类，此时前端没有使用element的分页组件，返回的数据需要做修改  
```java
// 前台返回讲师的分页，与后台系统有区别
@Override
public Map<String, Object> getPageFrontTeacher(long currentPage, long limit) {
    Page<EduTeacher> eduTeacherPage = new Page<EduTeacher>(currentPage, limit);
    baseMapper.selectPage(eduTeacherPage, null);
    HashMap<String, Object> map = new HashMap<>();
    map.put("pageTeacherInfo", eduTeacherPage);
    map.put("hasNext", eduTeacherPage.hasNext());
    map.put("hasPrevious", eduTeacherPage.hasPrevious());
    return map;
}

前端

api定义接口地址

// 分页查询讲师
 getPageTeacher(currentPage, limit) {
     return request({
         url: `/eduservice/front-teacher/pageTeacher/${currentPage}/${limit}`,
         method: 'get'
     })
 },

使用异步请求调用查询讲师方法，相当于created（），在页面渲染之前调用
```javascript

前台课程详情

后端

在页面上显示的内容封装为一个VO对象

@ApiModel(value = "课程基本信息", description = "编辑课程基本信息的表单对象")
@Data
@AllArgsConstructor
@NoArgsConstructor
public class CourseInfoVO  implements Serializable {
 private static final long serialVersionUID = 1L;

 @ApiModelProperty(value = "课程ID")
 private String id;

 @ApiModelProperty(value = "课程讲师ID")
 private String teacherId;

 @ApiModelProperty(value = "课程二级分类ID")
 private String subjectId;

 @ApiModelProperty(value = "课程一级分类ID")
 private String subjectParentId;

 @ApiModelProperty(value = "课程标题")
 private String title;

 @ApiModelProperty(value = "课程销售价格，设置为0则可免费观看")
 private BigDecimal price;

 @ApiModelProperty(value = "总课时")
 private Integer lessonNum;

 @ApiModelProperty(value = "课程封面图片路径")
 private String cover;

 @ApiModelProperty(value = "课程简介")
 private String description;
}

controller，查询章节后台管理已有方法，查询课程VO对象需要多表查询，使用sql语句实现

@GetMapping("getFrontBaseCourse/{courseId}")
public ResultEntity getFrontBaseCourse(@PathVariable String courseId) {
 // 查询课程的VO对象（sql语句查询）
 FrontBaseCourseVO frontBaseCourseVO = eduCourseService.getFrontBaseCourse(courseId);
 // 根据课程id查询章节
 List<ChapterVO> chapterVOList = eduChapterService.getChapterVO(courseId);

 return ResultEntity.ok().data("chapterList", chapterVOList).data("courseVO", frontBaseCourseVO);
}

service实现

@Override
public FrontBaseCourseVO getFrontBaseCourse(String courseId) {
 return baseMapper.getFrontCourseVO(courseId);
}

接口和sql
sql语句

FrontBaseCourseVO getFrontCourseVO(@Param("courseId") String courseId);

<select id="getFrontCourseVO" resultType="com.atguigu.eduservice.entity.vo.front.FrontBaseCourseVO">
 select ec.id,
        ec.title,
        ec.price,
        ec.lesson_num lessonNum,
        ec.cover,

        et.avatar,
        es1.id        subjectLevelOneId,
        es1.title     subjectLevelOne,
        es2.id        subjectLevelTwoId,
        es2.title     subjectLevelTwo

          LEFT JOIN edu_teacher et ON ec.teacher_id = et.id
          LEFT JOIN edu_subject es1 ON ec.subject_parent_id = es1.id
          LEFT JOIN edu_subject es2 on ec.subject_id = es2.id
          LEFT JOIN edu_course_description ecd on ec.id = ecd.id
 where ec.id = #{courseId}
</select>

前端

api定义接口地址

// 根据课程id查询课程的相关信息
 getFrontBaseCourse(courseId) {
     return request({
         url: `/eduservice/front-course/getFrontBaseCourse/${courseId}`,
         method: 'get'
     })
 }
