Java Json序列化与JsonView

我有一个要序列化的类，忽略了一些属性

public class User extends Model
{
    static class publicView{}

    @JsonView(publicView.class)
    private Long id;

    private String showName;

    @JsonView(publicView.class)
    private List<qQueue> callableQueues;

}

如何使用“publicView”类进行序列化？

您可以将对象映射器配置为包含您的

publicView.class

并排除其他字段，如下所示：

• 禁用

  MapperFeature.DEFAULT\u VIEW\u INCLUSION

  mapper功能
• 通过

  ObjectMapper#getSerializationConfig（）.withView（）方法启用视图进行序列化

请参阅以供参考

以下是一个例子：

public class JacksonView1 {
    public static class publicView{}

    public static class User  {
        public User(Long id, String showName, List<String> callableQueues) {
            this.id = id;
            this.showName = showName;
            this.callableQueues = callableQueues;
        }
        @JsonView(publicView.class)
        public final Long id;

        public final String showName;

        @JsonView(publicView.class)
        public final List<String> callableQueues;
    }

    public static void main(String[] args) {
        User user = new User(123l, "name", Arrays.asList("a", "b"));
        ObjectMapper mapper = new ObjectMapper();
        mapper.disable(MapperFeature.DEFAULT_VIEW_INCLUSION);
        mapper.setConfig(mapper.getSerializationConfig()
                .withView(publicView.class));
        System.out.println(mapper.convertValue(user, JsonNode.class));
    }
}

多亏了阿列克西·加夫里洛夫，我找到了一个解决方案，它可能不是最合适的，但很有效

public JsonNode jsonSerialization()
{
    ObjectMapper mapper = new ObjectMapper();
    try 
    {
        mapper.disable(MapperFeature.DEFAULT_VIEW_INCLUSION);
        return Json.parse(mapper.writerWithView(publicView.class).writeValueAsString(this));
    } 
    catch (JsonProcessingException ex) 
    {
        return null;
    }
}

我找不到setConfig方法，可能此方法已更改？是的，此方法已添加到版本2.0中。对于1.X，还有其他方法。请参阅此页面：我不需要让行

mapper.disable（MapperFeature.DEFAULT\u VIEW\u INCLUSION）。它与
mapper.setConfig（mapper.getSerializationConfig（）.withView（publicView.class））配合得非常好
{"id":123,"callableQueues":["a","b"]}

public JsonNode jsonSerialization()
{
    ObjectMapper mapper = new ObjectMapper();
    try 
    {
        mapper.disable(MapperFeature.DEFAULT_VIEW_INCLUSION);
        return Json.parse(mapper.writerWithView(publicView.class).writeValueAsString(this));
    } 
    catch (JsonProcessingException ex) 
    {
        return null;
    }
}
