REST,Tomcat,Jersey,IntelliJ,产生404

这让我疯了。我已经尝试了大约五个关于同一错误的Stack Overflow问题,但无济于事。

我的web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
    <display-name>Spotitube</display-name>
    <servlet>
        <servlet-name>Jersey Web Application</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>jersey.config.server.provider.packages</param-name>
            <param-value>com.spotitube</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey Web Application</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>
</web-app>

我的服务:

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/myresource")
public class myresource {

    /**
     * Method handling HTTP GET requests. The returned object will be sent
     * to the client as "text/plain" media type.
     *
     * @return String that will be returned as a text/plain response.
     */
    @GET
    @Produces({ MediaType.TEXT_HTML, MediaType.TEXT_PLAIN })
    public String getIt() {
        return "Got it!";
    }
}

我的pom.xml,它应该以某种方式相关:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                <version>${jersey.version}</version>

    </dependencies>

    <properties>
        <jersey.version>2.23.2</jersey.version>
    </properties>
</project>

index.jsp只包含一个指向localhost:8080 / rest / myresource服务的链接。 URL签出。

我尝试过Tomcat 7和8.5。我的IDE是IntelliJ 2017.2.5。我已经按照我所遵循的教程添加了所有jar文件,并且Tomcat工作正常。只有在RESTful页面(而不是index.jsp)才会给出404。

我现在感到愚蠢。任何人都有任何线索可能会发生什么?

3 个答案:

答案 0 :(得分:1)

因为地图网址为localhost:8080/myresource而不是localhost:8080/rest/myresource

答案 1 :(得分:0)

首先,检查应用程序上下文是&#34; /&#34;。

其次,正如Mehraj Malik所说,检查映射URL是否正确。

答案 2 :(得分:0)

除了Mehraj所写的内容(使用@Path("/rest/myresource"))之外,您可能忘记在web.xml中定义您的球衣应用程序

<servlet>
    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.your.company.project.JerseyApplication</param-value>
    </init-param>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.spotitube</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

在任何情况下,如果您可以在您的球衣应用程序中发布可能有帮助的相关代码。

应该这样开始:

@ApplicationPath("/")
public class JerseyApplication extends ResourceConfig {
