使用Jersey 2的REST API [英] REST API using Jersey 2

问题描述

我想使用Jersey 2实现REST API，我希望将资源分成接口和它们的实现，例如：

I would like to implement a REST API using Jersey 2 and I would like to have resources separated into interfaces and their implementations like e.g.:

@Path("hello")
public interface HelloLogic {
    @GET
    @Produces("application/json")
    public String hello();
}

public class HelloLogicResource implements HelloLogic {
    public String hello() {
        return "{\"reply\": \"Hello\"}";
    }
}

我没有任何运气来获取资源。对于刚刚提到的hello资源，我希望以下内容足够：

I do not have any luck getting the resources exposed though. For the hello resource just mentioned I was hoping that the following would be enough:

public class MyApplication extends ResourceConfig {
    public MyApplication() {
        register(new MyApplicationBinder());
    }
}

public class MyApplicationBinder extends AbstractBinder {
    @Override
    protected void configure() {
        bind(HelloLogic.class).to(HelloLogicResource.class);
    }
}

web.xml：

<servlet>
    <servlet-name>MyApplication</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>stines.api.MyApplication</param-value> 
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>MyApplication</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

pom.xml：

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.4.1</version>
</dependency>

但是点击

http://localhost:8080/hello

我收到404回复：

输入将不胜感激:)谢谢。

Input will be greatly appreciated :) Thanks.

新发现：它适用于此：

public class MyApplication extends ResourceConfig {
    public MyApplication() {
        registerClasses(HelloLogicResource.class);
    }
}

推荐答案

这工作：

public class MyApplication extends ResourceConfig {
    public MyApplication() {
        registerClasses(HelloLogicResource.class);
    }
}
