部署eclipse+tomcat+spring mvc遇到的若干问题

1、spring mvc 

cvc-complex-type.2.4.c: The matching wildcard is strict, but mvc:default-servlet-handler

取消空行即可

2、org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature 'span' not found

span注释掉

3、Dynamic Web Module 3.1 requires Java 1.7 or newer.

在pom.xml中增加

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>

直接修改.setting中的org.eclipse.wst.common.project.facet.core.xml

4、java版本问题

保证windows->preferences->java->Compiler

windows->preferences->java->Installed Jres

project->preferences->java compiler

project->preferences->project facets->java

保持一致
