专门分析一下fastxml.json的序列化，偶有所得，截图如下：


另一个示例

public class User {
    public interface WithoutPasswordView {};
    public interface WithPasswordView extends WithoutPasswordView {};

    private String username;
    private String password;

    public User() {
    }

    public User(String username, String password) {
        this.username = username;
        this.password = password;
    }

    @JsonView(WithoutPasswordView.class)
    public String getUsername() {
        return this.username;
    }

    @JsonView(WithPasswordView.class)
    public String getPassword() {
        return this.password;
    }

    public static void main(String[] args) throws IOException {
        ObjectMapper objectMapper = new ObjectMapper();
        //创建对象
        User user = new User("isea533","123456");
        //序列化
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        objectMapper.writerWithView(User.WithoutPasswordView.class).writeValue(bos, user);
        System.out.println(bos.toString());

        bos.reset();
        objectMapper.writerWithView(User.WithPasswordView.class).writeValue(bos, user);
        System.out.println(bos.toString());
    }
}

输出结果

{"username":"isea533"}
{"username":"isea533","password":"123456"}
