string类型转换,jsonarray转换成list

三种转换方法 String courseData = "...";List<Course> courseTable;courseTable = JSON.parseObject(courseData, new TypeReference<List<Course>>() {});courseTable = JSON.parseArray(courseData, Course.class);courseTable = JSON.parseArray(courseData).toJavaList(Course.class);System.out.println(courseTable);

光亮的茉莉，第三种方法：

Code // ListList<Course> courseTable = new LinkedList<>();courseTable.add(new Course("1", "Java", 30, 3.0));courseTable.add(new Course("2", "乐观的金毛, 25, 2.5));System.out.println(courseTable);// List -> StringString str = JSON.toJSONString(courseTable);System.out.println(str);// String -> JSONArrayJSONArray objects = JSON.parseArray(str);System.out.println(objects);// JSONArray -> ListList<Course> courses = objects.toJavaList(Course.class);System.out.println(courses);
