在Tomcat7上部署webapp

标签： java spring maven tomcat jetty


我的问题是我试图在Tomcat上部署基于Spring的webapp。出于习惯，我将嵌入式码头用于测试，并且工作正常。当我停止tomcat并运行它时，整个应用程序正确响应。当我尝试在Tomcat上部署它时问题就开始了（它需要以这种方式部署，因为它将如何在生产中部署）。

我的主要课程：

package pl.tracer.config;

import java.util.logging.Level;
import java.util.logging.Logger;

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.util.resource.ResourceCollection;
import org.eclipse.jetty.webapp.WebAppContext;

public class Main {

private static Logger logger = Logger.getLogger(Main.class.getName());

public static void main(final String[] aArgs) throws Exception {

    logger.log(Level.INFO, "Starting");
    final Server server = new Server(8080);
    server.setHandler(createWebAppContext());

    server.start();
    server.join();
}

private static WebAppContext createWebAppContext() {
    final WebAppContext context = new WebAppContext();
    context.setContextPath("/");
    context.setBaseResource(new ResourceCollection(
            new String[] { "./src/main/java/META-INF/webapp" }));
    logger.log(Level.INFO, "Created context");
    return context;
}
}

的web.xml：

<?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_2_5.xsd"
id="WebApp_ID" version="2.5">

<display-name>RunTracer</display-name>

<servlet>
    <servlet-name>tracer</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>tracer</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

示踪剂servlet.xml中：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:p="http://www.springframework.org/schema/p"

<context:component-scan base-package="pl.tracer" />
<mvc:annotation-driven />
</beans>

唯一（简单）控制器：

package pl.tracer.requestHandling;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

import pl.tracer.entities.Track;

@Controller
@RequestMapping(value = "/")
public class TrackController {

@Autowired
private TrackService service;

@ResponseBody
@RequestMapping(method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
public Map<Long, List<Track>> getAll(
        @RequestParam(required = true) List<Long> ids,
        @RequestParam(required = false) Integer count) {
    Map<Long, List<Track>> map = new HashMap<>();
    for (Long id : ids) {
        List<Track> tracks = service.getAll(id, count);
        map.put(id, tracks);
    }
    return map;
}
}

正如您所看到的，它尽可能简单。 我还附加了tomcat的日志：

有人可以帮助我，并说明为什么这个应用程序不允许我执行简单的GET 

"http://localhost:8080/tracer?ids=1"

？我总是收到404错误。

只是为了确保在tomcat上部署带有嵌入式jetty的webapp是可能的 - 我已经尝试了几次并且它有效。

1 个答案:

答案 0 :(得分：1)

嵌入式码头与此无关。启动jetty的那个主类只是被动的，在tomcat中将它作为webapp部署时不会被调用。

这条线引起了我的注意

    new String[] { "./src/main/java/META-INF/webapp" }));

看起来您的webroot不是通常的地方。我想在那种情况下你应该告诉tomcat使用docBase。您可以在手册或Change the root context to other folder in tomcat 6

等地方查看

还有一些jar冲突（基本上是servlet-api等）。您是否在tomcat日志或经理应用程序中检查应用程序是否已正确启动？我看到你已经开始了。我猜网址类似于http://localhost:8080/manager左右
