jackson jboss eap6.1.1 注释不起作用 [英] jackson jboss eap6.1.1 annotations not working

问题描述

我一直在尝试在 EAP 6.1.1 服务器上的 JBoss RestEasy 应用程序中使用 Jackson 注释.更确切地说，我想让 JacksonPolymorphicDeserialization 像 done 这里.

I have been trying to get Jackson annotations working in the JBoss RestEasy application on a EAP 6.1.1 server. To be more exact I want to get the JacksonPolymorphicDeserialization working through there annotation like done here.

现在看起来很简单，但由于某种原因，它并没有真正起作用.我得到以下代码:

Now it seems simple enough but for some reason it’s not really working. I got the following code:

package example.model;

import com.fasterxml.jackson.annotation.JsonSubTypes;
import com.fasterxml.jackson.annotation.JsonTypeInfo;

@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = JsonTypeInfo.As.PROPERTY, property = "@type",visible = true)
@JsonSubTypes({@JsonSubTypes.Type(value = ImplementedRequest.class, name = "implementedrequest")})
public abstract class Request {

}

以及抽象类的实现:

@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = JsonTypeInfo.As.PROPERTY, property = "@type", visible = true)
public class ImplementedRequestextends Request {
    @NotEmpty
    private Person applicant;

    private List<AbstractApplicationPart> applications;

}

我创建了一个发出请求并处理请求的端点:

I created a endpoint that makes a request and processes a request:

@Path("serviceRequest")
@Named("RequestResource")
@RequestScoped
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
@ValidateRequest
@IgnoreMediaTypes(MediaType.APPLICATION_JSON)
public class RequestResource {
   public Boolean saveRequest( @Valid Request request, @Context HttpServletRequest req) throws JAXBException, AnError {
//Some awesome processing happens here
}
public Response getDummyData() {
// Creates and fills the ImplementedRequestextends
return result;
}
}

现在我也做了一些配置，并确保我在 Jboss 中加载了带有 war 部署的 Jackson 模块.并确保在我的 pom 中我的版本与模块相同.

Now I also did some configuration and made sure I load the Jackson modules in Jboss with the war deployment. And made sure in my pom I have the same version as the Modules.

我现在的期望是，如果我打电话，我会得到类似的信息:

My expectation is now that if I do a call I get something like:

{
    "applicant": { "name":"Dummy data", "age":31},
    "applications": [ {"sport":"soccer"},{"sport":"judo"}    ]
}

我希望得到一个带有 implementedrequest 字段的 @type 名称.这是我的第一次尝试；最终我也想让抽象数组像这样工作.但我什至无法让它工作.

I was expecting to get a @type name with the field implementedrequest. This is my first attempt; eventually I also want to have the abstract array work like this. But I can't even get this working.

推荐答案

所以最后我弄清楚出了什么问题.

So in the end I figured out what went wrong.

import com.fasterxml.jackson.annotation.JsonSubTypes;
import com.fasterxml.jackson.annotation.JsonTypeInfo;

是不是有问题.Jackson 有 2 个版本并且都可以工作，但 JBoss EAP6.1.1 的默认版本是 org.codehaus 下的 1.X 分支.问题这两种方法都在核心下工作.它后来移到了不同​​的分支和工件.

Is the problem. Jackson has 2 versions and both work, but the default for JBoss EAP6.1.1 is the 1.X branch wich is available under org.codehaus. The problem both methods work under the core. It's later moved to a different branch and artifact.
