Moxy，JSON和Jersey 2.0不会反序列化纯字符串数组 [英] Moxy, JSON and Jersey 2.0 does not deserialize plain String array
问题描述
在我当前的设置中，我将球衣2.0与MOXy配合使用，如球衣中所述文档.我完全依靠 自动发现功能"，因此我不使用任何额外的配置或JAXB注释.
In my current setup I use Jersey 2.0 with MOXy as discribed in jersey docs. I rely completely on the "Auto-Discoverable Features", so I do not use any extra configuration or JAXB annotation.
我的任务是在服务器端反序列化字符串数组.客户端正在发送JSON消息:
My task is to deserialize an array of strings on the server side. The client is sending the JSON message:
["foo","bar"]
在服务器端，以下方法标头应将其反序列化:
And on the server side the following method header should deserialize it:
@POST
@Path("/stringArray")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Response stringArray(List<String> stringList) {
...
}
问题: stringList的内容为{null，null}，因此元素的数量始终是正确的，但是字符串设置为null.
Problem: The content of stringList is {null,null}, so the amount of elements is always correct, but the strings are set to null.
与小型包装器类相同的方法也可以正常工作.这里是班级:
The same with a small wrapper class is working. Here the class:
public static class Data {
public List<String> stringList;
}
将方法签名更改为stringArray(Data data)并将JSON消息更改为:
Changing methode signature to stringArray(Data data) and changing the JSON message to:
{"stringList": ["foo","bar"]}
这两种方法之间有什么区别?如何使纯字符串数组正常工作?
What is the difference between the two approaches and how can I get the plain string array working?
更新: 通过@Blaise的答复解决了所描述的问题.但是，与序列化POJO列表紧密相关的问题仍然无法解决.讯息:
Update: The described problem is fixed by answer from @Blaise. But the closely related problem of serializing a List of POJOs does still not work. Message:
[org.glassfish.jersey.message.internal.MessageBodyProviderNotFoundException: 找不到针对媒体类型= application/json的MessageBodyWriter， type = class java.util.ArrayList，genericType = class java.util.ArrayList.]
[org.glassfish.jersey.message.internal.MessageBodyProviderNotFoundException: MessageBodyWriter not found for media type=application/json, type=class java.util.ArrayList, genericType=class java.util.ArrayList.]
我发现的唯一解决方案是再次使用包含List ...的小型包装器类.
The only solution I found is again using a small wrapper class containing the List...
