Spring controllers not found - spring

Question

I am unable to call spring MVC controller. Everytime I hit it, it says not found.
My files are as following.
Web.xml
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/gk1</url-pattern>
</servlet-mapping>
spring-servlet.xml
<mvc:annotation-driven />
<context:component-scan base-package="com.gkool" />
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>/WEB-INF/views/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
</bean>
<mvc:resources mapping="/resources/**" location="/resources/" />
</beans>
My controller file
package com.gkool;
#Controller
#RequestMapping("/score")
public class ScoreController {
Logger log = Logger.getLogger(ScoreController.class);
#RequestMapping(value = "", method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Hello World");
return "hello";
}
#RequestMapping(value = "/hello/{name}", method = RequestMethod.GET)
public ModelAndView hello(#PathVariable("name") String name) {
ModelAndView model = new ModelAndView();
model.setViewName("hello");
model.addObject("msg", name);
return model;
}
}
when I start sever and hit URL http://localhost:8080/gk1/score or http://localhost:8080/gk1/score/hello/anoop It gives error code 404 not found.
P.S. /gk1 is module name in tomcat.
When I start the tomcat server it gives following logs
org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping registerHandlerMethod
INFO: Mapped "{[/score/hello/{name}],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public org.springframework.web.servlet.ModelAndView com.gkool.ScoreController.hello(java.lang.String)
Feb 07, 2017 10:37:11 PM org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping registerHandlerMethod
INFO: Mapped "{[/score],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String com.gkool.ScoreController.printWelcome(org.springframework.ui.ModelMap)
Feb 07, 2017 10:37:12 PM org.springframework.web.servlet.handler.SimpleUrlHandlerMapping registerHandler
INFO: Mapped URL path [/resources/**] onto handler 'org.springframework.web.servlet.resource.ResourceHttpRequestHandler#0'
That means it identifies a mapped URL as /score/hello/{name} but when I start my server in debug and put a debugger breakpoint in the controller method, the debug control doesn't come there.
can anyone please help?

Answer 1

Check if you've defined the context web within the tomcat configuration of your application:
<Context docBase="/path/to/myapp.war" path="/myContext" reloadable="true"/>
Now execute the request like this:
http://localhost:8080/myContext/gk1/score/hello/anoop
But if you've defined like:
<Context docBase="/path/to/myapp.war" path="/gk1" reloadable="true"/>
Then in the web.xml servlet configuration you just have to define the servlet mapping like this:
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

Fix your Spring configuration.
<mvc:annotation-driven />
is a configuration element.
This is required for Spring to "find" your controllers:
<context:component-scan base-package="your.controller.package"/>
Per the Sotirios Delimanolis comment, the following configuration
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/gk1</url-pattern>
</servlet-mapping>
Tells tomcat to send requests with exactly match this URL: http://localhost:8080/gk1 to the spring servlet.
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/gk1/*</url-pattern>
</servlet-mapping>
Which tells tomcat to send any request that starts with the URL http://localhost:8080/gk1 to spring.
The * is the difference between: "exactly match" and "starts with".
