这个问题很明显是JDK1.8.0_111没有生效，版本不一致，我们系统当中，目前配置的JDK版本号是多少？

和我们的版本号是一致的，没有问题，然后去看项目使用的JDK是多少

从上图可以看到，目前项目用到的版本号不统一，我们把它们统一下。

集中定义版本号：

           
                org.apache.maven.plugins
                maven-compiler-plugin
                ${maven-compiler-plugin.version}
                
                    ${java.version}
                    ${java.version}
                    ${project.build.sourceEncoding}
                
            

如上设置好后再重新打包编译ok!
