该错误是由于maven编译的时候使用了jdk1.3,而jdk1.3不支持范型.


错误原因：
（1）用mvn -v  查看maven版本

引用

Apache Maven 2.2.1 (rdebian-4)
Java version: 1.6.0_24
Java home: /usr/lib/jvm/java-6-sun-1.6.0.24/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux" version: "2.6.35-22-generic" arch: "amd64" Family: "unix"

版本依赖是1.6
（2）maven2.2.1 默认使用jdk1.3编译

解决办法:
  在项目的pom.xml中，添加：

<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
</plugins>
</build>
