Question

I have a spring application and I can’t solve a problem. When I use a PathVariable, the value in my RequestMapping is getting added to the URI and the DispatchHandler is getting confused.

For example, when I request /Dashboard/project/1131/

I get HTTP Status 404 - /Dashboard/project/1131/WEB-INF/jsp/projectDetail.jsp

The project/1131 gets added into the path for some reason

When I request /Dashboard/projects Spring finds my .jsp and presents it. /project/{projectId} doesn’t work – I get the behavior described above.

Here’s my controller

@Controller
public class ProjectController {

protected final Log logger = LogFactory.getLog(getClass());

@RequestMapping(value = "projects", method=RequestMethod.GET)
public String projects() {
    return "/projects";
}

@RequestMapping(value="/project/{projectId}", method=RequestMethod.GET)
public String project(@PathVariable("projectId") String projectId, ModelMap map) {
    map.put("projectId", projectId);
    logger.info("Project Id: " + projectId);
    return "/projectDetail";
}

}

My configuration

AppConfig

@Configuration

@Bean
ViewResolver viewResolver() {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("WEB-INF/jsp/");
    resolver.setSuffix(".jsp");
    return resolver;
}

}

dashboard-servlet.xml…

This has to be simple – but I have looked through the documentation and searched the internet for hours. It looks like I am doing everything right from what I can see.

Answer 1

I think having a leading slash in resolver.setPrefix("/WEB-INF/jsp/"); should fix it for you.
