java - 运行 spring 简单示例

Question

我正在尝试完成该教程 http://blog.springsource.com/2011/01/04/green-beans-getting-started-with-spring-mvc/但我就在 Hello world 之前被困住了应该出现在我的浏览器中...

在 pom.xml我得到:<finalName>ex1</finalName>所以我要去http://localhost:8080/ex1/并得到:HTTP Status 404 - Servlet appServlet is not available 。我保存 Controller 的包的名称与文章中的名称略有不同，但 maven build .war成功地。

我也可能对 jstl 有一些问题所以我也添加到我的pom文件中:

    <dependency>
        <groupId>jstl</groupId>
        <artifactId>jstl</artifactId>
        <version>1.1.2</version>
    </dependency>

但这也没有帮助。我尝试的另一件事是遵循以下说明:Eclipse "cannot find the tag library descriptor" for custom tags (not JSTL!) ，也没有成功。

我正在使用tomcat 6 @ ubuntu。

如果有人能帮助我，我将非常感激。

这就是今天 tomcat6 的日志:

INFO: Deploying web application archive ex1.war 2011-08-29 17:13:50 org.apache.catalina.startup.HostConfig checkResources INFO: Undeploying context [/ex1] 2011-08-29 17:13:50 org.apache.catalina.startup.HostConfig deployWAR INFO: Deploying web application archive ex1.war

重启tomcat6后出现一些错误:

Answer 1

添加此行

<display-name>ex1</display-name>

到 web.xml

编辑:

添加异常跟踪后:检查ServletDispatcher的类名并检查pom.xml中的sprinmwc依赖
