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

问题描述

我一直在尝试使杰克逊注释在EAP 6.1.1服务器上的JBoss RestEasy应用程序中工作.更确切地说，我想让 JacksonPolymorphicDeserialization 像在

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.

现在看来已经足够简单了，但是由于某种原因，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 {

}

和抽象类的实现:

@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，我还进行了一些配置，并确保通过战争部署将Jacksson模块加载到Jboss中.并确保在pom中使用与模块相同的版本.

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"}    ]
}

我期望得到一个@type名称，其中包含implementedrequest字段.这是我的第一次尝试；最终，我也希望抽象数组像这样工作.但是我什至无法正常工作.

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

所以最终我找出了出问题的地方.

So in the end I figured out what went wrong.

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

是问题. Jackson有2个版本，并且都可以使用，但是JBoss EAP6.1.1的默认值为1.c分支，在org.codehaus下可用.两种方法都在核心下起作用.后来将其移至其他分支和工件.

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.
