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();
}
