JacksonFeature打破了JsonIgnoreProperties

问题描述

我有这样的pojo：

@JsonIgnoreProperties(ignoreUnknown = true)
public class SNAPIResponse {

    public String status;
    public String message;
    public int errorCode;

    public ConsumerProfile consumerProfile;

    @JsonIgnoreProperties(ignoreUnknown = true)
    public static class ConsumerProfile {
        public String accountId;
    }
}

我的泽西客户端工作正常，即使 ConsumerProfile 回复包含很多额外字段。

and my Jersey client works just fine even though the ConsumerProfile responses contain a lot of extra fields.

然后我添加一行：

client.register(JacksonFeature.class);

到我的Jersey客户端设置。之后，忽略不再起作用：

to my Jersey Client setup. And after that, the ignore's don't work anymore:

Unrecognized field "authService" (Class com.xyz..SNAPIResponse$ConsumerProfile), not marked as ignorable

为什么？

推荐答案

我偶然发现了这篇文章，帮助我让JsonIgnoreProperties再次运作：

I stumbled across this post which helped me get JsonIgnoreProperties working again: http://jersey.576304.n2.nabble.com/Beware-of-JacksonFeature-in-Jersey-td7581633.html

我没有足够的研究来100％确定问题的根本原因，但似乎注册JacksonFeature.class会引入一个过时版本的库。

I didn't research enough to be 100% sure on the underlying cause of the issue, but it seems registering JacksonFeature.class pulls in an outdated version of a library needed for this.

按照该链接的建议行事对我有用。

Doing as suggested in that link worked for me.
