Question

我是RestEasy网络服务的新手。我从restEasy Web-Serivce得到了正确的回复，但当我尝试编写一个Web服务客户端时，我发现错误。请找到如下代码。请告诉我问题在哪里。我正在使用RestEasy 3.0.9 Final。

RestServiceClient.java

import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.Response;

public class RestServiceClient {

public static void main(String[] args) throws Exception {
    Client client = ClientBuilder.newBuilder().build();
    WebTarget target = client.target("http://localhost:8888/RestSpring/rest/response/hello");
    Response response = target.request().get();
    String value = response.readEntity(String.class);
    System.out.println("Response Value : "+value);
    response.close(); 
   }

}

Answer 1

尝试使用相应版本的resteasy-multipart-provider：

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-multipart-provider</artifactId>
    <version>${resteasy.version}</version>
</dependency>

2.2.0似乎很老了

Answer 2

更改版本后，删除了javax.ws.rs-api jar从服务器获取响应。这是配置文件，如下所示。
