我是 Spring MVC 的新手，我只是尝试一个基本的示例。但我收到 Http Stats 404 错误。我的文件如下:
这是一个maven项目。
/Web-Inf/spring-mvc-demo-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- Step 3: Add support for component scanning -->
<context:component-scan base-package="springdemo" />
<!-- Step 4: Add support for conversion, formatting and validation support -->
<mvc:annotation-driven/>
<!-- Step 5: Define Spring MVC view resolver -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
然后我有 WEB-INF/web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
id="WebApp_ID" version="3.1">
<display-name>spring-mvc-demo</display-name>
<!-- Spring MVC Configs -->
<!-- Step 1: Configure Spring MVC Dispatcher Servlet -->
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-mvc-demo-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Step 2: Set up URL mapping for Spring MVC Dispatcher Servlet -->
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
/WEB-INF/view/main-page.jsp
<html>
<body>
<h1>Welcome to home page!!!!</h1>
</body>
</html>
然后是 src/HomeController.java
package springmvcdemo;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestMapping;
@Component
public class HomeController {
@RequestMapping("/")
public String startPage(){
return "main-page";
}
}
我正在 Eclipse IDE 中创建一个动态 Web 项目，它是一个 Maven 项目，我尝试在其上运行它的服务器是 Tomcat 8.0.44
有人可以帮我消除这个错误吗？
最佳答案
我看到 spring-mvc-demo-servlet.xml 中的包名称与您拥有 Controller 的包不匹配。
spring-mvc-demo-servlet.xml:-
<context:component-scan base-package="springdemo" />
家庭 Controller ，
package springmvcdemo;
