[英]Openshift Spring MVC Tomcat application's deployed path returns 404
[英]Jersey application deployed on Tomcat returns 404
我試圖編寫一個REST服務,並從Tomcat啟動它。 我的web.xml
是:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<display-name>TomcatRestExample</display-name>
<servlet>
<servlet-name>Jersey Web Application</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>de.continentale.testsvn.rest</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey Web Application</servlet-name>
<url-pattern>/maven/*</url-pattern>
</servlet-mapping>
</web-app>
我的課程de.continentale.testsvn.rest.RestCaller
看起來像:
package de.continentale.testsvn.rest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
@Path("/service")
public class RestCaller {
@GET
@Produces(MediaType.TEXT_XML)
public String convert() {
return "<text>hallo</text>";
}
}
我嘗試訪問http://localhost:8090/TomcatRestExample/maven/service
但得到了:
HTTP Status 404 - /TomcatRestExample/maven/service
type Status report
message /TomcatRestExample/maven/service
description The requested resource is not available.
Apache Tomcat/7.0.41
Eclipse中的Tomcat控制台輸出:

知道我缺少什么嗎?
看起來您的上下文不正確。 您的應用程序部署在/tomcat-rest-test
而不是/TomcatRestExample
。 后者只是管理工具使用的顯示名稱。 Tomcat使用WAR文件名(不帶.war
)作為上下文名稱。
因此,使用http://localhost:8090/tomcat-rest-test/maven/service
來訪問您的資源方法。
看來您的上下文是/tomcat-rest-test
而不是/TomcatRestExample
。 嘗試第一個: localhost:8090/tomcat-rest-test/maven/service
。
