我也有遇到这种情况，右键项目-->properties-->java compile， 将里面的默认的1.5改成你的jdk版本，OK

pm.xml里加入下面这一行试试。
<profiles>
<profile>
<id>jdk-1.8</id>
<activation>
<activeByDefault>true</activeByDefault>
<jdk>1.8</jdk>
</activation>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
</properties>
</profile>
</profiles> -

1，可以用maven clean命令clean一下，然后项目在maven上选择update project；
2，可以选择navigator模式查看，或者查看隐藏文件里的JAVA编译模式。
3，再不行重新启动eclipse。
