@Override
public String sayHello(String name) {
return "Hello: " + name;
}
}
I call it from browser with; 我用浏览器来称呼它;
http://localhost/HelloRest/rest/hello/sayHello?name=me
but it returns Not found. 但返回“找不到”。
If I call; 如果我打电话
http://localhost/HelloRest/aa/index.html,
I can see the content of index.hmtl. 我可以看到index.hmtl的内容。
What is my problem and how can I fix it? 我的问题是什么,如何解决?
Note: I deploy it with Wildfly-10.1 注意:我将其与Wildfly-10.1一起部署
Try to change your Servlet deployment code as given below. 尝试按以下说明更改Servlet部署代码。 With this deployment all the @Path classes found in your web application will be available with the URL pattern /rest/*
通过此部署,您的Web应用程序中找到的所有@Path类都将以URL模式/ rest / *可用。
<servlet>
<servlet-name>javax.ws.rs.core.Application</servlet-name>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>javax.ws.rs.core.Application</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
@Narayana's answer is perfectly valid but you could instead forgo the web.xml all together and have a single additional Java file that, for now, lives in the same directory as your code and looks something like: @Narayana的答案是完全正确的,但是您可以一起放弃web.xml并拥有一个单独的其他Java文件,目前该文件与您的代码位于同一目录中,如下所示:
package hellorest;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
/**
* Used to bootstrap the rest services. This class is not directly used.
*/
@ApplicationPath("/services")
public class RestApplicationConfig extends Application {
// intentionally empty
}
Notice the "/services" annotation - this says that your services will be accessed at /services so in your example it is likely to be http://localhost:8080/HelloRest/services/hello/sayHello 注意“ / services”注释-这表示将在/ services处访问您的服务,因此在您的示例中,它可能是http:// localhost:8080 / HelloRest / services / hello / sayHello
