[英]Deploying webapp on Tomcat7

问题描述


我的问题是我试图在Tomcat上部署基于spring的webapp。 由于不习惯于将我嵌入码头进行测试，所以效果很好。 当我停止tomcat并运行它时，整个应用程序都正确响应。 当我尝试将其部署到Tomcat时，问题就开始了（因为需要将其部署在生产环境中，因此需要采用这种方式进行部署）。

我的主班： 

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;
}
}

web.xml中： 

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

示踪剂servlet.xml中：

唯一（简单）的控制器： 

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.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;
}
}

如您所见，它非常简单。 我还附上来自Tomcat的日志：

有人可以帮我吗，并说为什么这个应用程序不能让我执行简单的GET操作 

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

？ 我总是会收到404错误。

只是为了确保，可以在tomcat上部署带有嵌入式码头的Web应用程序-我已经尝试了几次，并且奏效。

嵌入式码头与此无关。 您拥有的启动码头的主类只是被动的，在将其作为WebApp部署在tomcat中时不会被调用。

这条线引起了我的注意 

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

看起来您的webroot不在通常的地方。 我猜在那种情况下，您应该使用docBase告诉tomcat有关。 您可以在手册中或类似的位置中看到将root上下文更改为tomcat 6中的其他文件夹

也有一些jar冲突（基本上是servlet-api等）。 您是否在tomcat日志或管理器应用程序中检查了应用程序是否已正确启动？ 我看到你已经开始了。 我想网址会像http://localhost:8080/manager
