我正在尝试开发一个简单的 Spring MVC Web 应用程序。 我收到 HTTP 状态 404 -/SimpleMVC/WEB_INF/HelloPage.jsp 请求的资源不可用。 我是 Spring MVC 新手。
这是我的 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>SimpleMVC</display-name>
<servlet>
<servlet-name>front-controller</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>front-controller</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
这是我的前端 Controller 。
<bean name="/welcome.html" class="controller.HelloController"></bean>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix"> <value>/WEB_INF/</value>
</property>
<property name="suffix"> <value>.jsp</value></property>
</bean>
这是我的 Controller :
package controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;
public class HelloController extends AbstractController {
@Override
protected ModelAndView handleRequestInternal(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
ModelAndView giveBackMessage = new ModelAndView("HelloPage");
giveBackMessage.addObject("welcomeMessage","This is the response got from Controller");
return giveBackMessage;
}
}
This is my Response JSP:
<html>
<body>
<h1>$(welcomeMessage)</h1></body>
</html>
I dont know where i am missing. Please help me where i am going wrong
最佳答案
您在 viewResolver 中提到了错误的前缀。
<property name="prefix"> <value>/WEB_INF/</value>
正确的应该是
<property name="prefix"> <value>/WEB-INF/</value>
还有
<h1>$(welcomeMessage)</h1></body>
应该是
<h1>${welcomeMessage}</h1></body>
