测试
添加有关项目设置的更多详细信息-文件夹、htlp、jsp文件、web.xml等。在url“/test/”？@ShankarPS donether中添加您期望的详细信息。您可以执行以下步骤来测试此代码。1.在webapp文件夹和tst下添加一个默认index.html文件，如果调用url时显示该文件-localhost:8081。2） 确保error404.jsp有一些代码，并查看是否显示这些代码。1.在webapp文件夹和tst下添加一个默认index.html文件，如果调用url时显示该文件-localhost:8081。2） 确保error404.jsp有一些代码，看看是否有显示。@ShankarPS ehh我仍然得到一个空白页。。error404.jsp和tomcat本地主机访问日志中有一些代码如下127.0.0.1--[15/Feb/2020:01:54:35+0300]“GET/test/HTTP/1.1”200-127.0.0.1--[15/Feb/2020:01:54:35+0300]“GET/HTTP/1.1”4047330:0:0:0:0:1--[15/Feb/2020:01:54:35+0300]“GET/test/HTTP/1.1”200-
