使用 maven 和 tomcat 运行 spring mvc-basic 示例

Question

使用 Tomcat 6.0，Maven 3。我对这一切都很陌生，所以请有人帮助我吗？

我以https://src.springframework.org/svn/spring-samples/mvc-basic/trunk/ 为例。

我从 pom.xml 目录执行 mvn package 命令，将 mvc-basic.war 文件带到 Tomcat 的 webapps 目录，重新启动 tomcat 并转到 localhost:8080/mvc-basic/。

但我得到的只是某种tomcat错误500：

我下载了现成的战争，它运行良好。下载后我没有更改项目代码，但是在尝试生成自己的战争时它不起作用。

请帮帮我，我哪里出错了？

ROO 也遇到过类似的问题，这是因为 Hibernate Validator。所以，我猜你在这里面临同样的问题。我希望您使用的是 Java 5。这个link 会有所帮助。

解决方案是在你的 pom.xml 中添加以下依赖。

<dependency>
   <groupId>javax.xml.bind</groupId>
   <artifactId>jaxb-api</artifactId>
   <version>2.1</version>
</dependency>

<dependency>
   <groupId>com.sun.xml.bind</groupId>
   <artifactId>jaxb-impl</artifactId>
   <version>2.1.3</version>
</dependency>
