Google Gson 禁止序列化内部类

1 新建包含内部类的 POJO 类

1. 
   
2. public class User {
4. private String account;
6. private String password;
8. private String name;
10. private int age;
12. private Address address;
14. public User() {}
16. public User(String account, String password, String name, int age, double longtitude, double latitude) {
17. this.account = account;
18. this.password = password;
19. this.name = name;
20. this.age = age;
21. this.address = new Address();
22. this.address.setLongtitude(longtitude);
23. this.address.setLatitude(latitude);
24. }
26. public class Address {
28. private double longtitude;
30. private double latitude;
32. public double getLongtitude() {
33. return longtitude;
34. }
36. public void setLongtitude(double longtitude) {
37. this.longtitude = longtitude;
38. }
40. public double getLatitude() {
41. return latitude;
42. }
44. public void setLatitude(double latitude) {
45. this.latitude = latitude;
46. }
48. @Override
49. public String toString() {
50. return "Address [longtitude=" + longtitude + ", latitude=" + latitude + "]";
51. }
53. }
55. public String getAccount() {
56. return account;
57. }
59. public void setAccount(String account) {
60. this.account = account;
61. }
63. public String getPassword() {
64. return password;
65. }
67. public void setPassword(String password) {
68. this.password = password;
69. }
71. public String getName() {
72. return name;
73. }
75. public void setName(String name) {
76. this.name = name;
77. }
79. public int getAge() {
80. return age;
81. }
83. public void setAge(int age) {
84. this.age = age;
85. }
87. public Address getAddress() {
88. return address;
89. }
91. public void setAddress(Address address) {
92. this.address = address;
93. }
95. @Override
96. public String toString() {
97. return "User [account=" + account + ", password=" + password + ", name=" + name + ", age=" + age + ", address="
98. + address + "]";
99. }
101. }

2 测试代码

1. 
   
2. @Test
3. public void test() throws IOException {
4. User user = new User("ACCOUNT", "PASSWORD", "NAME", 25, 99.9999, 111.1111);
5. Gson gson = new Gson();
6. System.out.println(gson.toJson(user));
7. gson = new GsonBuilder()
8. .disableInnerClassSerialization()
9. .create();
10. System.out.println(gson.toJson(user));
11. }

运行结果：
