Spring Controller

Question

I am trying to follow the Spring tutorial, but keep receiving a 404 error. Below is my Controller class:

@Controller
@RequestMapping("/updatedescription.htm")
public class UpdateDescriptionController {
    /** Logger for this class and subclasses */
    protected final Log logger = LogFactory.getLog(getClass());

    @Autowired
    private ProductManager productManager;

    @RequestMapping(value="/{description}", method=RequestMethod.GET) 
    public String updateDescription(@PathVariable("description") String description, Model model) {       
        return "redirect:/hello.htm";
    }

    @Autowired
    public UpdateDescriptionController(ProductManager productManager) {
        this.productManager = productManager;
    }
}

When I try and go to "http://localhost:8505/baseSpringMVC/updatedescription.htm/Chair" I get a 404 error.

I've setup my web.xml file to point all *.htm traffic to the DispatcherServlet...

<?xml version="1.0" encoding="UTF-8"?>

    </bean>

</beans>

Any help would be great.

Thank you!

It's not *.htm when you add /Chair onto the end of it. Post your web.xml so we can debug it.

Your class-level request mapping should not have ".htm". That is, change:

@RequestMapping("/updatedescription.htm")

to

@RequestMapping("/updatedescription")

If that doesn't fix it, we may need to see your Spring configuration file.

EDIT:

The top of your Spring config file, including the MVC namespace, should look something like this:

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" 
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:oxm="http://www.springframework.org/schema/oxm" 
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-3.0.xsd
http://www.springframework.org/schema/oxm http://www.springframework.org/schema/oxm/spring-oxm-3.0.xsd">

Tried that as suggested below. I'll add my *-servlet.xml file

GriffeyDog Over a year ago

Try adding this to your Spring config file: <mvc:annotation-driven />

Stacktrace: org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 14 in XML document from ServletContext resource [/WEB-INF/baseSpringMVC-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException: The prefix "mvc" for element "mvc:annotation-driven" is not bound. at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:396) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:334)

You need to define the mvc namespace at the top of the file. So you need xmlns:mvc="http://www.springframework.org/schema/mvc" and within xsi:schemalocation you need http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd.

Can you please clarify so I can cut and paste.

Change method to POST, test it and let me know so that we can debug further

@RequestMapping(value="/{description}", method=RequestMethod.POST)

That's not working either. It's coming from a link, so I believe it has to be a GET.

Java P Over a year ago

Do you have below line:<context:component-scan base-package="controller package" />

Dan Over a year ago

Yes, that's within the baseSpringMVC-servlet.xml file

Dan Over a year ago

No, I am at work and they block those sites here. It's coming from the Spring tutorial though

Java P Over a year ago

Do you have <mvc:annotation-driven /> in your configuration

Remove the top level RequestMapping annotation on the controller. Your updateDescription method will dictate the request mapping.

static.springsource.org/spring/docs/3.0.x/reference/… section 15.3.2. Says you can have the top level controller with each method having another mapping

Dan Over a year ago

updated link static.springsource.org/spring/docs/3.0.x/reference/…

Yes you can, but it at least should not have the ".htm" extension in it. You should make the URL equivalent to "localhost:8505/baseSpringMVC/updatedescription/Chair".
