Here's my Web.xml
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring/servlet-context.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
my servlet-context.xml
<context:component-scan base-package="com.springexample.controller.impl" />
<mvc:annotation-driven />
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>/WEB-INF/views/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
And lastly the Handler class. which is under com.springexample.controller.impl
@Controller
public class IndexControllerImpl implements IndexController {
@RequestMapping("/")
public String index() {
return "index";
}
}
However on going to localhost:8080/projectname/
it returns a 404 error.

Here is my project structure
This question is related to
java
spring
model-view-controller
spring-mvc
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>

change to:

Try passing the Model object in your index method and it will work-
@RequestMapping("/")
public String index(org.springframework.ui.Model model) {
return "index";
}
Actually the spring container looks for a Model object in the mapping method. If it finds the same it will pass the returning String as view to the View resolver.
Hope this helps.
With the web.xml configured they way you have in the question, in particular:
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
ALL requests being made to your web app will be directed to the DispatcherServlet
. This includes requests like /tasklist/
, /tasklist/some-thing.html
, /tasklist/WEB-INF/views/index.jsp
.
Because of this, when your controller returns a view that points to a .jsp
, instead of allowing your server container to service the request, the DispatcherServlet
jumps in and starts looking for a controller that can service this request, it doesn't find any and hence the 404
.
The simplest way to solve is to have your servlet url mapping as follows:
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
Notice the missing *
. This tells the container that any request that does not have a path info
in it (urls without a .xxx at the end), should be sent to the DispatcherServlet
. With this configuration, when a xxx.jsp
request is received, the DispatcherServlet
is not consulted, and your servlet container's default servlet will service the request and present the jsp as expected.
Hope this helps, I realize your earlier comments state that the problem has been resolved, but the solution CAN NOT be just adding method=RequestMethod.GET
to the RequestMethod
.
First check whether the java classes are compiled or not in your [PROJECT_NAME]\target\classes directory.
If not you have some compilation errors in your java classes.
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
Hey Please use / in your web.xml (instead of /*)
I added META-INF folder with context.xml contain
<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/SpringGradleDemo"/>
SpringGradleDemo is my project name and it work. My servlet-mapping is "/" I read it here https://tomcat.apache.org/tomcat-5.5-doc/config/context.html
I have the same problem....
I change my project name and i have this problem...my solution was the checking project refences and use /
in my web.xml (instead of /*
)
