问题
so as the title says I'm getting an error a
[org.springframework.web.servlet.PageNotFound] (default task-1) No mapping for GET /ProjectFE/
how should I fix this? Also, there's no error in the code.
here is my code:
web.xml file-
<?xml version="1.0" encoding="UTF-8"?>

homepage.java file:
package controller;
import org.springframework.stereotype.Controller;

@Controller
public class HomeController {
@RequestMapping(value="/", method=RequestMethod.GET)
public String home()
{
return "homepage";
}
}
After running the code on server here's what i'm getting:

First of all arrange your web.xml
like this
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<!-- Processes application requests -->
<servlet>
<servlet-name>appServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
WEB-INF/spring-config.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
As you are defining contex-param
you don't need to use init-param
same xml file.
Now change a little in spring-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans
xmlns="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
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">
<mvc:annotation-driven/>
<resources mapping="/resources/**" location="/resources/" />
<beans:bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/Views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
<context:component-scan base-package="controller" />
</beans:beans>
Look carefully in line <beans:property name="prefix" value="/Views/" />
. Your folder name is Views
but you defined view
. That's why perhaps you are getting error.
Give a shout if it works.
