我正在尝试通过引用此网站来创建简单的网络服务:http://www.connect2java.com/webservices/jax-rs-applicationpath-annotationno-web-xml-example-in-jersey/
我正在使用
NetBeans IDE 8.0.2
Java 8.0 JDK 1.7
JBoss服务器
这是我的代码:
RestfulApplicationPathAnnotationExample.java:
package com.connect2java.RestfulApplicationPathAnnotationExample;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
@Path("/hello")
public class RestfulApplicationPathAnnotationExample {
@GET
@Produces(MediaType.TEXT_HTML)
public Response sayHello() {
String str ="<H1>Hi!!! welcome to @ApplicationPath Annotation Example in Restful webservices </H1> ";
return Response.status(200).entity(str).build();
}
}
MyApplication.java:
package com.connect2java.RestfulApplicationPathAnnotationExample;
import javax.ws.rs.ApplicationPath;
import org.glassfish.jersey.server.ResourceConfig;
@ApplicationPath("resources")
public class MyApplication extends ResourceConfig {
public MyApplication() {
packages("com.connect2java.RestfulApplicationPathAnnotationExample");
}
}
的web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<session-config>
<session-timeout>
30
</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
运行输出:
服务器上显示错误:
13:06:39,832 INFO [TomcatDeployer] undeploy, ctxPath=/RestfulApplicationPathAnnotationExample, warUrl=.../tmp/deploy/tmp7253522143789622225RestfulApplicationPathAnnotationExample-exp.war/

See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class
计划结构:
我在此网址的网页上显示“Hello World”输出:
http://localhost:8080/RestfulApplicationPathAnnotationExample/
但是当我尝试这个网址时:
http://localhost:8080/RestfulApplicationPathAnnotationExample/resources/hello
我收到此错误消息:
HTTP Status 404 - /RestfulApplicationPathAnnotationExample/resources/hello
The requested resource (/RestfulApplicationPathAnnotationExample/resources/hello) is not available.
有人可以帮帮我吗?
答案 0 :(得分:0)
WEB-INF \ lib \ javax.servlet-api-3.0.1.jar) - jar未加载。请参阅Servlet规范2.3,第9.7.2节。“
这是一个警告(不是错误)。您不应该部署任何包含javax.servlet
类的jar。容器会忽略它。只需从javax.servlet-api-3.0.1.jar
.war
即可
关于你的路径问题,似乎球衣遗漏了@ApplicationPath("resources")
。尝试添加/
前缀here @ApplicationPath("/resources")
