我已按照此处描述的详细信息配置了泽西(使用tomcat服务器),直到此处的步骤6.3: http://www.vogella.com/tutorials/REST/article.html#jerseyprojectsetup
下面是我的web.xml文件,唯一的区别是jersey.config.server.provider.packages
说明书已经;
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.vogella.jersey.first</param-value>
因为com.vogella.jersey.first
是他们的包名,而我选择指向我的默认包(jerseytest)
但这是我的web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>jerseytest</display-name>
<servlet>
<servlet-name>Jersey REST Service</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<!-- Register resources and providers under com.vogella.jersey.first package. -->
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>jerseytest</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>
当我在tomcat服务器上运行应用程序时,我一直得到:
HTTP状态404 - 未找到
输入状态报告
Message /jerseytest/
描述源服务器未找到当前表示 对于目标资源或不愿意披露存在的资源。
Apache Tomcat / 8.5.23
当我将浏览器指向教程中提到的结束点时:
http://localhost:8080/com.vogella.jersey.first/rest/hello
我收到一个未找到的错误:
HTTP状态404 - 未找到
输入状态报告
Message Not Found
描述源服务器未找到当前表示 对于目标资源或不愿意披露存在的资源。
Apache Tomcat / 8.5.23
当我将浏览器直接指向http://localhost:8080/rest/hello
时我明白了:
HTTP状态404 - 未找到
输入状态报告
Message /rest/hello
描述源服务器未找到当前表示 对于目标资源或不愿意披露存在的资源。
Apache Tomcat / 8.5.23
我的java类与说明中的示例相同,不同之处在于我的默认包:
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
// Plain old Java Object it does not extend as class or implements
// an interface
// 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)
public String sayXMLHello() {
return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
}
// This method is called if HTML is request
@GET
@Produces(MediaType.TEXT_HTML)
public String sayHtmlHello() {
return "<html> " + "<title>" + "Hello Jersey" + "</title>"
+ "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
}
}
答案 0 :(得分:5)
我多次挣扎于这个问题。
我目前使用的解决方案是使用webapp(或保存jsp等视图的文件夹)处于部署程序集中。
要这样做
右键单击project > Build Path > Configure Build path > Deployment Assembly > Add(right hand side) > Folder > (add your jsp folder. In default case it is src/main/webapp)
答案 1 :(得分:0)
每种方法都需要指定路径
像这样:
@GET
@Path("testOne")
@Produces(MediaType.TEXT_HTML)
