Eclipse+Tomcat+maven+springMVC环境搭建出错总结

出错一：

Eclipse+maven+springMVC环境搭建时 在jetty下没有问题（采用的方式是在控制台执行 mvn jetty:run指令方式），但是在 Eclipse+Tomcat+maven+springMVC

严重: Servlet [mvc-dispatcher] in web application [/spring-mvc-learning] threw load() exception

这种问题是由于 deployment assembly maven依赖没有添加。

解决方法：右击工程，选择properties，左边拉到最上面选择Deployment Assembly



点击Add按钮，选择Java Build
Path Entries，点击Next



选择 Java Build Path Entries,点Next



选择Maven Dependencies,点击Finish后Apply



这时候重启下tomcat就完美运行了。



出错二：

报错 java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.Config

解决方法：在pom.xml 中加

<dependency>

<groupId>javax.servlet</groupId>

<artifactId>jstl</artifactId>

<version>1.2</version>

<scope>runtime</scope>

</dependency>
