二、这是什么问题？ 怎么解决问题？
有网友这么描述并解决问题的：Installed JREs 使用本机的JDK，这样貌似可以解决部分问题：具体操作如下：
如何查看自己本机的JDK呢？
之后改为自己本机的JDK；
改变之后的错误藐视确实和之前的不太一样了。

基本错误描述就是说编译的jdk不相符导致的，因此可以，看了一下项目的jdk确实是这样的。我已经我项目的jdk改成了1.8.0_77但是项目的jdk还是
因此在这里必须手动改变一下jdk版本：
改变之后的jre版本如下：
重新运行之后的结果如下：错误信息还是如下：尝试失败，但是又排除了一种可能，还是有进步的，继续探索。

再次尝试解决：“”我也出现了这种情况 改变系统的jdk 而不是jre 或者升级jdk版本我也出现了这种情况 ”这是在CSDN上的其他同仁给出的意见，抱着尝试的心态去试试。但是怎么改变Eclipse中的JDK版本的？
需要解决的问题： 怎么改变或者更新eclipse中的JDK版本？
其实在运行的结果中已经很明确的指定了错误信息了。
No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
就是说你导入的是一个JRE而不是一个JDK，因此导入JDK试试看。

我电脑上的JDK找不到，查看不了源码，因此打算卸载了重新安装JDK和JRE；
重新安装JDK8的安装教程：http://jingyan.baidu.com/article/ab69b270c01a4d2ca7189f8c.html
科普：
Java SE=Java Standard Edition
Java EE=Java Enterprise Edition
Java ME=Java Mobile Edition
SE主要用于桌面程序,控制台开发(JFC)
EE企业级开发(JSP,EJB) 一般是开发Web应用
ME嵌入式开发(手机,小家电)
目前的JDK大致分三个大版本：
Java SE：Java Platform, Standard Edition，Java平台标准版，主要用来开发桌面程序
Java EE：Java Platform, Enterprise Edition，Java平台企业版，主要用来开发WEB程序
Java ME：Java Platform, Micro Edition，Java平台微缩版，主要用来开发移动程序
如果你已经写了servlet，估计就是一直在用Java EE技术，也许你没有使用Oracle提供的官方的Java EE SDK
在Java的中间发展阶段，曾经把上面的名字叫做J2SE、J2EE、J2ME
其中的2读作英语two，剩下的按照字母发音，2代表第二代的意思
我真的想报警了，几个小时过去了，JDK也重装了，但是还是没有解决问题：

折腾了一天问题终于有结果了：
有一位网友的回答比较含蓄但是很有用，他的解决办法是这样的：
我在这里用截图的方式表达一下：
首先你在Eclipse中导入你的JRE：
但是这个也不是主要的问题，也有可能是由于编码问题导致的。以下的这两个编码都应该注意：
这个问题先告一段落吧，可能有点乱，但是这是我解决问题的思路，假如能对大家有所帮助当然不胜荣幸。
