404在Glassfish上调用Jersey 2 REST端点 [英] 404 when calling Jersey 2 REST endpoint on Glassfish

问题描述

这是我的web.xml

 < servlet> 
< servlet-name>模拟器HTTP API< / servlet-name> 
< servlet-class> org.glassfish.jersey.servlet.ServletContainer< / servlet-class> 
<加载启动> 1< /加载启动> 
< / servlet> 
< servlet-mapping> 
< servlet-name>模拟器HTTP API< / servlet-name> 
< url-pattern> / *< / url-pattern> 
< / servlet-mapping> 
< / web-app> 
  

这是我简单的web服务：

  @Path（partner）
 public class PartnerAPI {
 
 @Path（/ mt）
 @GET 
 @Produces（MediaType.TEXT_PLAIN）
 public String sendMT（）{
 returnSent; 
} 
 
} 
  

当我这样称呼它时：

  http：// localhost：8080 / myprojectname / partner / mt 
  

我发现404错误mot，我做错了什么？

更新

这是我的maven

 <依赖关系> 
< groupId> org.glassfish.jersey.core< / groupId> 
< artifactId>球衣服务器< / artifactId> 
< version> 2.22.1< / version> 
< /依赖关系> 
< dependency> 
< groupId> org.glassfish.jersey.core< / groupId> 
< artifactId> jersey-common< / artifactId> 
< version> 2.22.1< / version> 
< /依赖关系> 
< dependency> 
< groupId> org.glassfish.jersey.core< / groupId> 
< artifactId>球衣客户端< / artifactId> 
< version> 2.22.1< / version> 
< /依赖关系> 
< dependency> 
< groupId> org.glassfish.jersey.containers< / groupId> 
< artifactId> jersey-container-servlet< / artifactId> 
< version> 2.22.1< / version> 
< /依赖关系> 
  

解决方案

在Jersey 2中有不同的部署选项： p>

如果你想通过 web.xml 来完成，你必须添加一个 init-

 < servlet> param 您可以指定应扫描哪些包。 
< servlet-name>模拟器HTTP API< / servlet-name> 
< servlet-class> org.glassfish.jersey.servlet.ServletContainer< / servlet-class> 
< init-param> 
< param-name> jersey.config.server.provider.packages< / param-name> 
< param-value> insert.packagename.where.your.class.is.here< / param-value> 
< / init-param> 
< / servlet> 
  

另一个选项是创建一个基本类来配置您的REST应用程序。

这看起来像这样：

  import javax.ws.rs.ApplicationPath; 
 import org.glassfish.jersey.server.ResourceConfig; 
 
 @ApplicationPath（/ test）
 public class YourApplication扩展ResourceConfig {
 public YourApplication（）{
 this.packages（insert.packagename.where。 your.class.is.here）; 
 
 
  

确保更新包名称所在的字符串你的 PartnerAPI 类是。

然后在 @ApplicationPath 到您的网址。

链接如下所示： http：// localhost：8080 / myprojectname / test / partner / mt

This is my web.xml

<servlet>
        <servlet-name>Simulator HTTP API</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Simulator HTTP API</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

and this is my simple web service:

@Path("partner")
public class PartnerAPI {

    @Path("/mt")
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String sendMT() {
        return "Sent";
    }

}

when i call it like this:

http://localhost:8080/myprojectname/partner/mt

i get 404 error mot found, what am i doing wrong?

Update

this is my maven

<dependency>
            <groupId>org.glassfish.jersey.core</groupId>
            <artifactId>jersey-server</artifactId>
            <version>2.22.1</version>
        </dependency>
        <dependency>
            <groupId>org.glassfish.jersey.core</groupId>
            <artifactId>jersey-common</artifactId>
            <version>2.22.1</version>
        </dependency>
        <dependency>
            <groupId>org.glassfish.jersey.core</groupId>
            <artifactId>jersey-client</artifactId>
            <version>2.22.1</version>
        </dependency>
        <dependency>
            <groupId>org.glassfish.jersey.containers</groupId>
            <artifactId>jersey-container-servlet</artifactId>
            <version>2.22.1</version>
        </dependency>

解决方案

You have different deployment options in Jersey 2:

If you want to do it via web.xml you have to add the an init-param where you specify which packages should be scanned:

<servlet>
        <servlet-name>Simulator HTTP API</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>jersey.config.server.provider.packages</param-name>
            <param-value>insert.packagename.where.your.class.is.here</param-value>
        </init-param>
</servlet>

Another option is to create a basic class to configure your REST application.

This would look like this:

import javax.ws.rs.ApplicationPath;
import org.glassfish.jersey.server.ResourceConfig;

    @ApplicationPath("/test")
    public class YourApplication extends ResourceConfig {
        public YourApplication() {
            this.packages("insert.packagename.where.your.class.is.here");
        }
    }

Make sure to update the string with the package name where your PartnerAPI class is.

Then add the value inside @ApplicationPath to your URL.
The link would look like this: http://localhost:8080/myprojectname/test/partner/mt
