@Service("courseService")
public class CourseServiceImpl implements CourseService {
public Course getCoursebyId(Integer courseId) {
Course course = new Course();
course.setCourseId(courseId);
course.setTitle("深入浅出Java多线程");
course.setImgPath("resources/imgs/course-img.jpg");
course.setLearningNum(12345);
course.setLevel(2);
course.setLevelDesc("中级");
course.setDuration(7200l);
course.setDescr("多线程是日常开发中的常用知识，也是难用知识。bala bala...");
按照教程把前面文件检查一遍，和视频里面一样还有就是编码格式都改为UTF-8即可
