I need to migrate a Spring web application to annotation.
It is using SimpleUrlHandlerMapping + ParameterMethodNameResolver, so url will be /myjob.do?cmd=addNew . what is the easiest way to convert it to Annotation ? is it something like this ?
#RequestMapping("/myjob.do?cmd=addNew")
public ModelAndView addNew(....) throws Exception {
}
thanks
Assuming you have more than one cmd value:
#Controller
#RequestMapping("/myjob.do")
public class MyController {
#RequestMapping(params = "cmd=addNew")
public ModelAndView addNew(....) throws Exception {
}
}

I have tried to find documentation on how to manually configure a RestController (i.e in a Configuation class). That means without using the RestController annotation. Considering all the other annotations, like mapping, pathvariables etc. is at all possible?
A controller is essentially a component with a request mapping. See RequestMappingHandlerMapping.
#Override
protected boolean isHandler(Class<?> beanType) {
return (AnnotatedElementUtils.hasAnnotation(beanType, Controller.class) ||
AnnotatedElementUtils.hasAnnotation(beanType, RequestMapping.class));
}
If you want to instantiate a "rest controller" through configuration, you can probably do so via the following:
#Configuration
public class MyConfiguration {
#Bean
public MyController() {
return new MyController();
}
}
#ResponseBody
public class MyController {
#RequestMapping("/test")
public String someEndpoint() {
return "some payload";
}
}
But I don't think you'll be able to configure the request mappings (path variables, etc) in the configuration though; at least I haven't seen an example nor figured out how.
I have a simple service built in Spring Boot that has a simple API. I've added the springfox libraries to use swagger and the swagger UI, but I do not want my application to serve the UI also. I just want to get the definition from from /api/v1/api-docs
How do I switch off the UI part? Not adding swagger-ui library as a dependency doesn't remove the UI for some reason.
You can block the UI and return HTTP code 404. Something similar to below
#Controller //note - this is a spring-boot controller, not #RestController
public class HomeController {
#RequestMapping ("/swagger/api/v1/api-docs")
public String home(HttpServletRequest request) {
throw new ResourceNotFoundException(); //Custom Solution
or
throw new NoSuchRequestHandlingMethodException(request);
}
}
#ResponseStatus(value = HttpStatus.NOT_FOUND)
public class ResourceNotFoundException extends RuntimeException {
...
}
If you are using Spring Boot
#SpringBootApplication
public class MyApp {
public static void main(String[] args) {
SpringApplication.run(MyApp.class, args);
}
#Bean
RouterFunction<ServerResponse> routerFunction() {
return route(GET("/swagger"), req ->
ServerResponse.temporaryRedirect("<some 404 page>").build());
}
}
My Spring Boot controller is working just fine, except that I cannot create a mapping for the home directory. I have tried:
#Controller
public class MyController {
#GetMapping(value = {"/"})
public ModelAndView searchPage(Locale locale) {
ModelAndView model = new ModelAndView();
model.setViewName("pageTemplate");
return model;
}
}
#GetMapping(value = "/")
#GetMapping(value = "")
#GetMapping
#RequestMapping with all values above
I always get my 404 error page. If this is supposed to work, how can I debug why it is not?
Found it. I set in application.properties:
logging.level.org.springframework.web: DEBUG
which then displayed
o.s.w.s.mvc.ServletForwardingController : Forwarded to servlet [springVaadinServlet] in ServletForwardingController 'vaadinUiForwardingController'
It turns out that I have used #SpringUI without specifying a path
I have a custom tag:
#Component
public class CVTag extends SimpleTagSupport {
#Inject
private JaxbSupport jaxbSupport;
#Override
public void doTag() throws JspException, IOException {
JspWriter writer = getJspContext().getOut();
Groups groups = jaxbSupport.getJaxbGroups();
}
NullPointerException is thrown as jaxbSupport is null.
Is there really a limitation stipulating Custom-Tag cannot be a Spring managed Bean? or I am doing something wrong?
Using Spring 3.2.4.
Thanks.
I am using spring AOP to check permission
#Component
#Aspect
public class PermissionManager {
#Around(value = "#annotation(requiredPermission) && args(id,..)", argNames = "id,requiredPermission")
public Object checkCanViewFile(ProceedingJoinPoint pjp, String id, RequiredPermission permission) throws Throwable {
...
}
}
Controller
#RequiredPermission(RequiredPermission.OperationType.editProject)
#RequestMapping("/searchFile")
public #ResponseBody
WebFile search(String id, String word) throws TokenExpiredException, FetchException {
...
}
It works on spring mvc test but can not working on real environment. the value of 'id' is null, I doubt spring AOP get this method before jackson objectmapper, is it right? How can fix it?
