fastjson使用public修饰 private转化Object有问题 注意事项

import java.util.ArrayList;import java.util.List;import com.alibaba.fastjson.JSON;class User {public Long id;public String name;int age;public String adress;List<String> teachers;public void setTeachers(List<String> teachers) {this.teachers = teachers;}public List<String> getTeachers(){return this.teachers;}}public class Test {public static void main(String[] args) {List<String> teachers = new ArrayList<>();for (int i = 0; i < 5; i++) {teachers.add(i+"");}User rootUser = new User();rootUser.id = 3L;rootUser.name = "root";rootUser.teachers = teachers;//rootUser.setTeachers(teachers);String jsonString = JSON.toJSONString(rootUser);System.out.println(jsonString);User user = JSON.parseObject(jsonString, User.class);System.out.println(user.id);//System.out.println(user.getTeachers());System.out.println(user.teachers);}}

版本：fastjson.jar 1.1.33

字段为非String 的Object时，若不是使用public修饰，则必须有对应的get、set方法，

字段类选为boolean时，必须使用public;

综合各种考虑，应当直接全部使用public修饰！
