JAX-RS：“ RESTEASY002005：执行GET org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure失败

问题描述

我创建了一个简单的服务，使我能够侦听传入的REST请求，然后执行任务，并将任务的输出作为自定义对象（MyObject）返回给调用方。

当我从IntelliJ执行它时，该服务运行得非常好[我假设jaxrs jar是从InteliJ的内部存储库中加载的]，但是当我从命令行执行jar时失败。例外如下：

[ERROR] RESTEASY002005: Failed executing GET /myapp/getVal

我的REST API代码如下：

@Path("/myapp")
@Singleton
public class MyResource {

    @GET
    @Path("/getVal")
    @Produces(MediaType.APPLICATION_JSON)
    public MyObject getVal(@QueryParam("id") @NonNull String id) throws Exception {
        try {
            return getMyObjData(id);
        } catch(IllegalArgumentException e) {
            throw new Exception(e.getMessage());
        }
    }
}

我经历了一些类似问题的链接，但没有一个帮助我。例如：

RestEasy: Could not find MessageBodyWriter for response object of type: java.util.ArrayList of media type: application/json

GET request fails with JAX-RS: Could not find MessageBodyWriter for response object of type: java.util.ArrayList of media type: text/html

simple example using resteasy-jaxrs not working

基于我使用IntelliJ进行的调试并在命令行上运行jar，在我看来，即使我添加了jar，但我尝试构建的jar却没有jaxrs的依赖关系（如果我没记错的话）到我的pom上。因此，我不确定如何处理此问题。有人可以帮我这个忙吗？

更新：

根据评论，我对父母和孩子的pom进行了如下更新：

即使进行了上述一组更改，我仍然看到相同的错误。

解决方法

问题类似于this one with Jersey，其中服务文件（用于自动注册提供程序）被排除在由maven-assembly-plugin构建的胖罐中。 solution将使用maven-shade-plugin，它具有一个转换器，可将所有服务文件的内容串联到一个uber jar的一个文件中。

经过几个小时的调试，我能够找到问题所在。从上面的pom文件可以看出，我正在使用Google Guice for DI。 使用Guice时，我们需要如下所示绑定JacksonProvider：

绑定（JacksonJsonProvider.class）

之所以在我的IDE上为我工作是因为IDE正在从其本地存储库（类路径）中加载必要的依赖项。

这为我解决了这个问题。
