如何遍历一个实例的所有属性，得到属性的名称和值

College college = this.collegeService.getCollegeById(id);
try {
        Field[] fields = college.getClass().getDeclaredFields();
        for (Field field : fields) {
            field.setAccessible(true);//类中的成员变量为private,须进行此操作 
            System.out.println( field.getName() + "=[" + field.get(college) + "];");
        }
    } catch (SecurityException | IllegalArgumentException | IllegalAccessException e) {
        e.printStackTrace();
    }
