tomcat8部署无法使用所请求的资源
每次我收到msg“请求的资源不可用”。我在spring框架中创建了一个maven项目。它的构建成功，但当我想用tomcate7或tomcate8执行时，它会给出同样的错误。 java版本是1.8。 它愚蠢的示例代码，我不知道为什么我会收到这个错误。
这里是代码段：

答案 0 :(得分：0)
我认为你的tomcat没问题，对我有用：
1.-右键单击您的项目 - ＆gt;属性 - ＆gt;部署组件 - ＆gt;添加 - ＆gt; Java构建路径条目 - ＆gt; Maven依赖
2.-在MvcConfiguration @ComponentScan中com.exp.aqua.controller的基本广告必须为index.jsp。
3.-在.jsp移除href属性中的<a href="home">扩展名：index.jsp
最后，请记住您的WebContent必须位于home.jsp文件夹和views中的 setContentView(R.layout.activity_main);
ListView listView = (ListView) findViewById(R.id.listView);
BackgroundWorker backgroundWorker = new BackgroundWorker(this, listView);
backgroundWorker.execute("argument");
。
