HTTP状态 500 - 内部服务器错误, D:javajavawebcodeoutartifactsfilepath

错误截图：

错误原因：

        ServletContext servletContext = getServletContext();
        String realPath = servletContext.getRealPath("thesamelevelasWEV-INF.txt");
        String realPath1 = servletContext.getRealPath("/WEV-INF/inWEB-INF.txt");
        文件夹名称写错正确的应该是：String realPath1 = servletContext.getRealPath("/WEB-            
        INF/inWEB-INF.txt");一定要注意细节。

        System.out.println("realPath = " + realPath);
        System.out.println("realPath1 = " + realPath1);

        FileInputStream fis = new FileInputStream(realPath);
        FileInputStream fis2 = new FileInputStream(realPath1);
        System.out.println("fis = " + fis);
        System.out.println("fis2 = " + fis2);
