错误信息：

Syntax error, annotations are only available if source level is 5.0

解决：
变更java Compiler 为6.0(我jdk为6)

右击项目选 Properties
然后如图。。

解决：
添加如下到pom.xml
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>

如图：
