resteasy javax.ws.rs.NotFoundException : Could not find resource for full path

Question

条件

1.resteasy 3.0.4.Final
2. eclipse
3. maven

行动

我将 war 包放入 tomcat7(window x64) webapps 并且服务器运行正常。
访问http://localhost:8080/test-resteasy/rest/message/hello ，浏览器打印“Restful example : hello”。
但是当我在 eclipse 中构建 tomcat7:run tomcat7-maven-plugin 时，访问相同的 url 抛出:

 javax.ws.rs.NotFoundException: Could not find resource for full path

MessageRestService

package top.crowley.resteasy;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;

@Path("/message")
public class MessageRestService {
    @GET
    @Path("/{param}")
    public Response printMessage(@PathParam("param") String msg) {

        String result = "Restful example : " + msg;

        return Response.status(200).entity(result).build();

    }

}

猜想

1. 我认为源代码是正确的，因为在单个 tomcat 7 服务器中成功运行 war 包。可能在 pom.xml 中缺少一些依赖项。

谢谢!

Answer 1

分析每个 POM 依赖项的文章真的很长......但是你为什么不尝试以这种方式编译 maven，官方 resteasy 团队建议？

mvn 全新安装
mvn 码头:运行
