运行弹簧简单的例子

我正在尝试完成该教程http://blog.springsource.com/2011/01/04/green-beans-getting-started-with-spring-mvc/，但是在Hello world出现在我的浏览器中之前我就被卡住了......

在pom.xml我得到：<finalName>ex1</finalName>所以我要去http://localhost:8080/ex1/并获得：HTTP Status 404 - Servlet appServlet is not available。我保留控制器的程序包与文章中的名称略有不同，但maven构建.war成功。

我可能也有jstl的问题，所以我也加入了我的pom文件：

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

但这也没有帮助。我尝试过的另一件事就是遵循这些指示：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，我会非常感激。

这就是今天tomcat6的日志：

重启tomcat6后出现了一些错误：

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

答案 1 :(得分：0)

您可以尝试将以下内容添加到pom.xml并访问

http://localhost:8080/ex1 

  <build>    
    <finalName>ex1</finalName>
  </build>

答案 2 :(得分：0)

您收到的课程未找到异常。你的类路径中是否有Spring-WebMVC jar文件？检查你的maven依赖。
