Question

我想从tomcat迁移到Wildfly 10.1，所以我创建了一个Web应用程序，用于在Wildfly上测试Jersey rest Web服务。

当我运行项目时，它会根据MultiPartFeature.class

显示错误

这是我的ApplicationConfigure.java

@ApplicationPath("api")
public class ApplicationConfigure extends ResourceConfig {


    public ApplicationConfigure() {

        register(JacksonJaxbJsonProvider.class);
        register(JacksonFeature.class);
        register(MultiPartFeature.class);

        packages(true, "com.example.controllers");

    }

}

这是错误（WildFly日志）：

当我删除MultiPartFeature.class时，它的部署非常好。

顺便说一句，这个应用程序很适合Tomee。

我该怎么办？我需要这个功能才能上传api

Answer 1

作为应用程序服务器，Wildfly提供了自己的JAX-RS规范实现。这里的框架是RESTEasy而不是Jersey。

那么从日志中可以看到它：

Caused by: java.lang.RuntimeException: RESTEASY003940: Unable to instantiate MessageBodyReader
    at org.jboss.resteasy.spi.ResteasyProviderFactory.registerProvider(ResteasyProviderFactory.java:1437)

RESTEasy引擎试图启动Jersey的功能，但未能这样做。在JAX-RS实现中没有那么多的统一，所以它们经常是不兼容的。

您有两种可能的解决方案

从泽西岛切换到RESTEasy。 multipart support有点不同
关闭Wildfly的RESTEasy扫描应用程序并在内部启动Jersey服务器。互联网上有很多关于它的文章。不确定哪种方法适用于您的版本。

Answer 2

我遇到了这个问题，并设法通过手动调用 JerseyClientBuilder().build()而不是ClientBuilder().build()。

泽西客户似乎是默认客户，因此，如果您定义了另一个客户，它将是ClientBuilder().build()选择的客户。

Answer 3

我在服务器和客户端级别将 Jersey 库版本从 1.x 升级到 2.x 时遇到了这个问题。

1.服务器级别更改：

在我的 web.xml 中添加了以下条目以消除类路径库中的 resteasy 扫描。

    <context-param>
        <param-name>resteasy.scan</param-name>
        <param-value>false</param-value>
    </context-param>
    <context-param>
        <param-name>resteasy.scan.providers</param-name>
        <param-value>false</param-value>
    </context-param>
    <context-param>
        <param-name>resteasy.scan.resources</param-name>
        <param-value>false</param-value>
    </context-param>

在我的 servlet 部分添加了以下提供者

    <servlet>
         ....
         ....
        <init-param>
          <param-name>jersey.config.server.provider.classnames</param-name>
          <param-value>
            com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider,
            org.glassfish.jersey.media.multipart.MultiPartFeature
          </param-value>
        </init-param>      
        ....
        ....
    </servlet>

2.客户端级别更改：

在升级过程中，我只是将客户端相关的类包从 com.sun.jersey.api.client 更改为 org.glassfish.jersey.client 并假设所有 glassfish jersey 的默认提供程序都将在客户端实例化期间注册，而不是 {{1 }} 被初始化，主要原因是，我使用 org.jboss.resteasy.spi.ResteasyProviderFactory 来创建客户端。此外，在问题发生后，将上述客户端创建更改为以下代码段，这导致我遇到了问题

<块引用>

找不到非具体 Map 类型的反序列化器 [map type; class javax.ws.rs.core.MultivaluedMap, [简单类型, class java.lang.String] -> [集合类型;类 java.util.List，包含 [简单类型，类 java.lang.Object]]] .

Client client = Client.create();

Json 解析问题是由于 org.glassfish.jersey.client.JerseyInvocation#translate 方法，其中实体读取发生在消息实体输入流中，作为指定 Java 类型的实例，使用 Client client = ClientBuilder.newClient(); WebTarget webResource = client.target(url); ClientResponse response = webResource.path(path).request("application/json") .header("Content-Type", "application/json;charset=UTF-8") .put(Entity.json(json), ClientResponse.class); if (response.getStatus() < 200 || response.getStatus() > 299) { throw new CustomException("HTTP Status: " + response.getStatus()); } String responseInString = response.readEntity(String.class); 用于 javax.ws 以外的类型.rs.core.Response`。

最后，通过完全采用 Jersey 家族的客户端类解决了上述问题。

工作客户：

javax.ws.rs.ext.MessageBodyReader

wildfly和jerseys MultiPartFeature.class
