什么是moxy相当于Jackson的JsonAnySetter？ [英] What is the moxy equivalent to Jackson's JsonAnySetter?

问题描述

我正试图转移到泽西岛2.0。这给了我杰克逊的痛苦，而且文档建议使用Moxy。

I'm attempting to move to Jersey 2.0. Which is giving me pains with Jackson, and the docs recommend using Moxy.

我让Moxy工作，获取和发布所有匹配良好的电话然而我需要处理可能未知的元素。

I got Moxy working for get and post calls where everything matches nicely however I have a need to deal with possible unknown elements.

// Handle unknown deserialization parameters
@JsonAnySetter
protected void handleUnknown(String key, Object value) {
    if (unknownParameters == null) {
        unknownParameters = new HashMap<>();
    }
    unknownParameters.put(key, value);
}

这在换到球衣2.0之前效果很好，即使它没有当我离开它时会导致任何问题从未被调用。

This worked well with prior to changing to jersey 2.0 and even though it doesn't cause any problems when I leave it in it never gets called.

我如何在Jersey 2.0中实现这一点？我对Moxy或Jackson很好。

How do I implement this in Jersey 2.0? I'm fine with Moxy or Jackson.

我的依赖

'org.codehaus.jackson:jackson-mapper-asl:1.9.2',
'org.eclipse.persistence:org.eclipse.persistence.moxy:2.5.0',
'org.glassfish.jersey.media:jersey-media-moxy:2.0',

这对我的网站没有影响.xml

This has no effect in my web.xml

<init-param>
    <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
    <param-value>true</param-value>
</init-param>

推荐答案

您可以使用 jersey- media-json-jackson 模块而不是MOXy来利用注释（我不确定MOXy是否支持类似的功能）。只需几个笔记：

You can use jersey-media-json-jackson module instead of MOXy to take advantage of the annotation (I am not sure whether MOXy has support for a similar feature). Just few notes:

• 删除 com.sun.jersey.api.json.POJOMappingFeature 来自 web.xml 的init参数 - Jersey 2.x无法识别此属性（特定于Jersey 1.x）


• 删除 org.glassfish.jersey.media:jersey-media-moxy:2.0 依赖


• 添加 org .glassfish.jersey.media:jersey-media-json-jackson：2.0 依赖和注册JacksonFeature 在您的申请中（见下文）

• remove the com.sun.jersey.api.json.POJOMappingFeature init parameter from your web.xml - Jersey 2.x does not recognize this property (it's Jersey 1.x specific)
• remove org.glassfish.jersey.media:jersey-media-moxy:2.0 dependency
• add org.glassfish.jersey.media:jersey-media-json-jackson:2.0 dependency and register JacksonFeature in your application (see below)

在这些步骤之后杰克逊应该处理对象< - > JSON（联合国）编组，它应该识别 @JsonAnySetter 。

After these steps Jackson should be handling Object<->JSON (un)marshalling and it should recognize @JsonAnySetter.

注册 JacksonFeature 在您的应用程序中，请参阅用户指南中的专用部分（ 8.1.4杰克逊）：

To register JacksonFeature in your application, see dedicated section in users guide (8.1.4 Jackson):

// Create JAX-RS application.
final Application application = new ResourceConfig()
        .packages("org.glassfish.jersey.examples.jackson")
        .register(MyObjectMapperProvider.class)  // No need to register this provider if no special configuration is required.
        .register(JacksonFeature.class);
