Java Tomcat/Spring集成返回404

我也有类似的问题

但我并没有犯和那张海报一样的错误，但我仍然得到了404

web.xml文件：

我可以转到localhost:8080/Test/index.jsp，但localhost:8080/Test/bench返回404

如果有帮助的话，我正在使用eclipse

编辑1：

这是logging.properties文件。除了日志外，我找不到任何日志

有趣的是，我不确定catalina.base变量是在哪里定义的

它似乎试图在/WEB-INF文件夹下找到dispatcher-servlet.xml。在查看war文件之后，我根本找不到该文件。每次我将servlet xml放入该文件夹时，它似乎都会被删除。我可以将它放在任何其他文件夹下，但由于某种原因，即使在更新WEB.xml以引用新位置之后，它仍然会在/WEB-INF下搜索文件

编辑5：

下面是我的web.xml的更新

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

但是当转到localhost:8080/Test/bench时，它仍然返回404。 当我通过tomcat manager部署时，我无法访问index.jsp，但如果通过eclipse部署，我可以访问index.jsp。catalina.out没有其他输出

解决方案：

---

我遵循下面提供的说明并在项目文件夹中，从命令行运行mvn eclipse:eclipse-Dwtpversion=2.0，以便eclipse能够正确导入项目。我正在研究如何在eclipse中实现这一点，以避免每次都需要手动完成。

您提到您想从头开始学习如何制作Spring MVC web app-以下是使用您的配置生成工作应用的步骤列表：

1） 创建文件夹

a

2） 在该文件夹中创建一个文件

pom.xml

4） 创建子文件夹

，并将两个文件

    <context:component-scan base-package="test" />

</beans>

5） 创建子文件夹

src/main/resources

并将

log4j.properties

文件放在那里：

log4j.rootLogger=INFO, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

6） 在文件夹

a

的命令提示中，键入：

mvn包

7） 将

target/test.war

复制到Tomcat的webapps文件夹中

8） 启动Tomcat并转到URL

localhost:8080/test/bench

我刚刚完成了所有的步骤，效果很好。

日志显示Spring消息，这些消息将告诉您是否有问题。

我能找到的唯一日志是/var/log/tomcat6/localhost.2012-02-18.log，但它不包含任何数据。好的，很抱歉，我的错误日志不是由tomcat生成的，而是由log4j生成的。那么在catalina.out中，你看到Spring的消息了吗？你看到了吗：

INFO:org.springframework.web.servlet.DispatcherServlet-FrameworkServlet'Spring MVC Dispatcher servlet'：初始化已开始

？你有

log4j-1.2.xx.jar

，

slf4j-api-1.6.x.jar

和

slf4j-log4j12-1.6.x.jar

吗？catalina.out没有。它仅显示启动/停止消息。我在/WebContent/WEB-INF/jsp下有yo.jsp。（/Webcontent由eclipse创建）。/Webcontent/WEB-INF/lib为空。但我在pom文件中声明了所有依赖项。我会在上面更新。另外，我确实在eclipse上遇到了一些问题，谷歌让我运行mvn eclipse:eclipse-Dwtpversion=2.0Hi。首先，感谢您花时间提供本教程。我从头开始的意思是，我试图通过eclipse创建一个maven/spring/dynamic web应用程序。主要原因是，当我需要调试某些东西时，我能够逐步完成代码。是的，您的示例非常有效，但每次我创建一个全新的web应用程序时都必须这样做，这将变得非常乏味。对不起，我无法帮助您设置Eclipse：（我将通过eclipse直接部署到tomcat manager。我得到失败-上下文路径/Test-0.1处的应用程序无法启动。org.apache.catalina.core.StandardContext startInternal severy:Error listenerStart 2012年2月19日下午6:57:12 org.apache.catalina.core.StandardContext startInternal severy:context[/Test-0.1]由于以前的错误，启动失败。我已经读到发生了异常。但是我在任何日志中都找不到它。我注释了org.springframework.web.context.ContextLoaderListener我认为异常是ClassNotFound。很难说没有看到日志。那么，您的dispatcher-servlet.xml在哪里？请按如下给出该路径：<代码>dispatcher org.springframework.web.servlet.DispatcherServlet 1 contextConfigLocation/web-INF/xx/dispatcher-context.xml

package test;
