在Java中动态更改JSON输出属性

public class Views {
    public static class Public {}
    public static class Internal extends Public {}
}

public class MyClass {
    private String publicField;
    private String internalField;

    @JsonView(Views.Public.class)
    public String getPublicField() {
        return publicField;
    }

    @JsonView(Views.Internal.class)
    public String getInternalField() {
        return internalField;
    }

    // 其他属性的getter和setter
}

ObjectMapper mapper = new ObjectMapper();
MyClass obj = new MyClass();
obj.setPublicField("Public value");
obj.setInternalField("Internal value");

String publicJson = mapper
    .writerWithView(Views.Public.class)
    .writeValueAsString(obj);
System.out.println("Public JSON: " + publicJson);

String internalJson = mapper
    .writerWithView(Views.Internal.class)
    .writeValueAsString(obj);
System.out.println("Internal JSON: " + internalJson);
