我只是在尝试REST webservice;标准样品; 虽然我能够创建战争并将其加载到WSO2 AS中,但当我尝试将其与客户端连接时,我得到HTTP 302的响应;我想知道错误可能在哪里; 以下是我的文件列表。
package com.indu.rs.test;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
// POJO, no interface no extends
// The class registers its methods for the HTTP GET request using the @GET annotation.
// Using the @Produces annotation, it defines that it can deliver several MIME types,
// text, XML and HTML.
// The browser requests per default the HTML MIME type.
//Sets the path to base URL + /hello
@Path("/hello")
public class Hello {
// This method is called if TEXT_PLAIN is request
@GET
@Produces(MediaType.TEXT_PLAIN)
public String sayPlainTextHello() {
return "Hello Jersey";
}
// This method is called if XML is request
@GET
@Produces(MediaType.TEXT_XML)

return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
}

@GET

302表示您正在被重定向。使用curl --verbose连接到端点,然后查看Location:标头。它应该为您提供有关正在发生的事情的线索。

好的,这是我最终从我的一个朋友那里得到的解决方案;
在web.xml中改变/休息 - &gt; /休息/ *
创建war文件并上传到服务器(在我的情况下为WSO2); 当服务器上传war文件时,它会使用上下文(在我的例子中为RSTest)
创建它最后转到浏览器类型:
http://localhost:9100/RSTest/rest/hello
你会看到一个成功的结果(在本例中是Hello Jersey)
