java - Jersey 和 JAX-RS

Question

我正在尝试使用 jersey 和 JAX-RS 部署最简单的 REST 服务，但出现此错误，

HTTP 错误:404未找到RequestURI=/hosting/demo/示例由 Jetty 提供支持://

我认为我所做的一切都是正确的，下面是我正在使用的代码。

POM.XML(只粘贴与 Jersey 相关的部分)

<dependency>
    <!-- the implementation of JAX-RS -->
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-server</artifactId>
    <version>1.0.1</version>
</dependency>
<dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-core</artifactId>
        <version>1.0.1</version>
</dependency>
<dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-client</artifactId>
        <version>1.0.1</version>
        <scope>compile</scope>
</dependency>

WEB.XML

<servlet>
        <servlet-name>jersey</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>com.sun.jersey.config.property.packages</param-name>
            <param-value>mop.core.service.restservices</param-value>
        </init-param>
</servlet>
<servlet-mapping>
        <servlet-name>jersey</servlet-name>
        <url-pattern>/demo</url-pattern>
</servlet-mapping>

我的类(class)有@GET

package mop.core.service.restservices;

import javax.swing.JOptionPane;
import javax.ws.rs.Consumes;
import javax.ws.rs.FormParam;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

@Path("/example")
public class PricePointRestService {
    @GET
    @Produces("text/plain")
    public String getPricePoint(){
        JOptionPane.showMessageDialog(null, "GET CALLED");
        return "hello";
    }

       @POST
       @Produces("application/xml")
       @Consumes({"application/x-www-form-urlencoded", "multipart/form-data"})
       public String doPost(@FormParam("xml") String xml) {
           return "<xml></xml>";
       }
}

我打的url是:http://localhost/hosting/demo/example

Answer 1

将 web.xml 中的 url-pattern 更改为:

<url-pattern>/demo/*</url-pattern>
