我只是尝试设置我的第一个spring-mvc应用程序,以便我可以使用框架。
但是,转到此url:localhost:8080 / springmvctest / home我收到404错误。但是,转到localhost:8080 / springmvctest我看到欢迎页面(index.jsp)
我在这里做错了什么?
Web.xml中

应用-config.xml中
<!-- Scans the classpath of this application for @Components to deploy as beans -->
<context:component-scan base-package="controller" />
<!-- Configures the @Controller programming model -->
<mvc:annotation-driven />
<!-- Resolves view names to protected .jsp resources within the /WEB-INF/views directory -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
控制器
@Controller
public class TestController {
@RequestMapping(value = {"/home","/","/index"}, method = RequestMethod.GET)
public String hello() {
return "home";
}
}
针对home.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>Hello home!</h1>
</body>
</html>

答案 0 :(得分:0)
此模式
<url-pattern>*.htm</url-pattern>
只会使数学表达式以htm和此url结尾:
localhost:8080/springmvctest/home
没有结束htm因此春天的调度员没有采取它。
<强>解决方案:强>
更改
<url-pattern>*.html</url-pattern>
到
<url-pattern>/*</url-pattern>
或
在您的控件中使用
@RequestMapping(value = {“/ home.htm”,“/ index.htm”},method = RequestMethod.GET)
