JAX-RS与TOMCAT 7的RESTEASY的异常

Question

我正在尝试用Resteasy实现一个RESTFULL服务。当我试图在Tomcat Server7.0中运行时，iam出现异常。请在下面找到详细信息。

package com.naresh.resteasy;

import javax.ws.rs.GET;
import javax.ws.rs.Produces;
import javax.ws.rs.Consumes;
import javax.ws.rs.Path;

@Path("/HelloResteasy")
@Produces("text/plain")
@Consumes("text/plain")
public class HelloService {

    @GET
    @Path("/response")
    public String printResponse(){
        return "Hello";

    }

}

package com.naresh.resteasy;

import java.util.HashSet;
import java.util.Set;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

-------------------------
@ApplicationPath("/service")
public class HelloApplication extends Application {

    private Set<Object> singletons = new HashSet<Object>();

    public HelloApplication() {
        singletons.add(new HelloService());
    }

    @Override
    public Set<Object> getSingletons() {
        return singletons;
    }

}

Answer 1

@path注释的值是区分大小写的字符串。在您的服务代码中，HelloService用@path（“/helloresteasy”）注释，但是您的请求路径是http://localhost:8080/resteasyhello/service/helloresteasy/response/

@ApplicationPath定义部署中所有JAX-RS服务的相对基URL路径。因此，在您的代码中，所有JAX-RS RESTful服务在执行时都应该以/services路径作为前缀。即http://localhost:8080/service/helloresteasy/response/
