网上找的原因大多是
1. jdk和Tomcat版本不对应
2. javax.servlet.jar 和 javax.servlet.jsp.jar 等包重复
但之前的页面都能正常运行，只有这一个界面不能请求，猜想应该不是上述问题。然后发现.jsp文件没有被编译，如图，因此应该是jsp页面中有什么问题导致.jsp页面没有被编译。
后来受Stack Overflow的启发，这里说jsp中导入的.java文件时的格式问题，想到是不是自己.jsp引入了什么错误的文件，发现引入了一个不存在的.java文件：Domain.News.java，直接删了这个引用就好了。因为直接复制的之前的代码，忘了删除引用的文件
因为jsp本质是一个servlet。在第一次请求jsp时，jsp会被容器转译为Servlet源代码、自动编译为.class文件、载入.class文件，然后生成Servlet对象。
