IntelliJ IDEA下使用默认Spring MVC框架运行失败的解决方案

IntelliJ IDEA下导入Spring MVC框架,直接运行失败,下面说明一下具体的解决步骤。

使用IDEA,直接导入Spring MVC框架

目录结构:

<!-- 使用注解的包,包括子集 -->
<context:component-scan base-package="com.wenjiehe.hello"/>
<!-- 视图解析器 -->

<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp"/>
</bean>
</beans>

在WEB-INF/jsp目录下创建hello.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
${message}
</body>
</html>

src目录下创建com.wenjiehe.hello.hello.java文件

@Controller
@RequestMapping("/hello")
public class hello {
@RequestMapping(method = RequestMethod.GET )
public String helloWorld(Model model){
model.addAttribute("message", "StringMvc你好啊!");
return "hello";
}
}

配置好tomcat即可运行,然后遇到一个问题:

28-Apr-2017 20:24:15.997 SEVERE [RMI TCP Connection(3)-127.0.0.1] org.apache.catalina.core.StandardContext.startInternal One or more listeners failed to start. Full details will be found in the appropriate container log file

这个问题可能出在lib加载的问题,解决办法是把lib文件夹放入WEB-INF目录下,同时添加为library。
问题解决的链接:Intellij IDEA 15创建的spring mvc项目无法运行。

这是第一个问题。第二个问题发现重新运行后的程序老是不能更新,找了下解决办法:intellij idea让资源文件自动更新

开始项目中没有 on frame deactivation 选项,在工程名上右击选择Open Module Settings,在Artifacts添加war exploded

至此就可以运行了。
