经过调查，发现了错误的原因，调查出来之后发现非常的简单，但是确实很难注意的到。

我在pom.xml文件中使用的

<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>${tomcat.version}</version>
<configuration>
<encoding>UTF-8</encoding>
<port>${webserver.port}</port>
<path>/${project.artifactId}</path>
<uriEncoding>${project.build.sourceEncoding}</uriEncoding>
</configuration>
</plugin>

我的tomcat.version用的是2.0，报刚才的异常。改成2.2，就正常了
