Answer 1

你的pom.xml是否设置了Java编译器版本？

maven-compiler的一些（所有？）版本采用Java 1.4编译器......这当然会引起问题，因为Annotations在Java 1.5中是新的。

您可以通过在项目的pom.xml中包含maven-compiler-version的插件块来强制它到Java 7并设置其源和目标属性......如下所示：

<project>
  [...]
  <build>
    [...]
    <plugins>
      <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>
    </plugins>
    [...]
  </build>
  [...]
</project>
