I want to accept file using inbound-gateway.
With regular Spring Boot it is pretty easy
#RequestMapping(method = RequestMethod.POST, path = "/upload/{configurationUid}", consumes = {"multipart/form-data"})
public void create(#RequestPart("file") MultipartFile file,#PathVariable String configurationUid){}
How to do the same with Spring Integration integration.xml? ASAIK, Spring Integration supports it but it is absolutely not clear for me how to write the appropriate inbound-gateway
That is so easy with Spring Integration as well.
You just need to configure new HttpRequestHandlingMessagingGateway() with an appropriate RequestMethod.POST, path. There is also RequestMapping object to accept consumes property.
The most important part is a multipartResolver bean, but it is already configured by Spring Boot via MultipartAutoConfiguration.
More info is in the Reference Manual and mentioned there HTTP Sample.

In my Spring boot app replacing a legacy, i have defined a webservice EndPoint.
soem of the user today comes in with payload that does nothave the namespace URI.
since namespace is not there, Spring throws No Endpoint mapping found error.
Is there a way i can add a default Endpoint so that it will get invoked if no mapping is found.
Thanks
You can try the following to create a fallback method for all request
#RequestMapping(value = "*", method = RequestMethod.GET)
#ResponseBody
public String getFallback() {
return "Fallback for GET Requests";
}

I'm using Spring Boot 2.0.2.RELEASE, and not being able to upload files for a REST controller endpoint.
Following this getting starter, it says:
As part of auto-configuring Spring MVC, Spring Boot will create a
MultipartConfigElement bean and make itself ready for file uploads.
So, theoretically, It should work without any additional configurations, but it looks like this MultipartConfigElement is not being configured at all.
I'm getting this warn:
WARN .a.w.r.e.DefaultErrorWebExceptionHandler: Failed to handle request [POST http://localhost:8080/upload]: Response status 400 with reason "Required MultipartFile parameter 'file' is not present"
My Spring application starter is as simple as:
#SpringBootApplication
public class MyApplication {
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
}
And my endpoint is:
#RestController
public class MyController {
#PostMapping("/upload")
public String hash(#RequestParam("file") MultipartFile file) {
final String test = file.getContentType();
}
This is the way I'm sending with postman:
I also made sure to unmark any default content type set by postman, with no success.
What possibly am I doing wrong?
First, add this to your properties file
servlet.multipart.enabled=true
servlet.multipart.max-file-size=20M
And create CommonsMultipartResolver bean as
(name = "multipartResolver")
Same question,but I got these files by this way.
You can found these files in this github repository:
gs-uploading-files
All you need to do is just download the zip file of this application,and find the files you need.
I am working on a web project and using Spring MVC 3.1.1. Spring MVC is used to serve REST services (using URL annotations)
Regarding to my problem:
Let's say my url path for a service is as;
http://localhost:8080/MyAppName/services/meteo/queryWeatherData/lon/39.1123/lat/39.3123
And my controller method is as;
#RequestMapping(method = RequestMethod.GET, value = {"/queryWeatherData/lon/{lon}/lat/{lat}"})
public void queryWeatherData(
final #PathVariable("lon") float lon,
final #PathVariable("lat") float lat,
final HttpServletResponse response, final HttpServletRequest request) {
//
// DO STUFF and prepare response
//
}
I see that the second parameter (lat) is truncated after "." so I see that the value is 39.0 in server side.
I tried declaring a DefaultAnnotationHandlerMapping bean in my app-context.xml and set its useDefaultSuffixPattern to false but it did not work.
How can I solve this issue?
Declaring the DefaultAnnotationHandlerMapping bean with useDefaultSuffixPattern=false is the right approach, but make sure you also comment out:
<mvc:annotation-driven />

I have been reading on Spring 3.2 lately and I am now trying the following code using Spring 2.5. From what I have read this should mean that it should map profile/tags/me. However it doesn't. It just throws a No mapping found for HTTP request with URI .... What is wrong with the code, or didn't Spring 2.5 work like it does in Spring 3?
Problem when using Spring 2.5
#Controller
#RequestMapping("/profile/tags")
public class ProfileController { ... }
And this is the method inside ProfileController class:
#RequestMapping(value = "/me", method = RequestMethod.GET)
public String show(#RequestParam final long id, final ModelMap model) { ... }
According to Spring documentation, I imagine you're missing the required configuration to receive the request parameter, if you mean to receive this request parameter:
#RequestMapping(value = "/me/{id}", method = RequestMethod.GET)
public String show(#RequestParam("id") final long id, final ModelMap model) { ... }
Or you should remove RequestParam.
Update for Spring 2.5
Additionally, since you're using Spring 2.5, make sure that you've configured your DispatcherServlet in the expected way; Sections 13.11, subsections 1, 2, and 3. In summary:
DispatcherServlet should be told to load annotated RequestMappings.
DispatcherServlet should be told to load Controller annotations.
Not sure but maybe you need to refine the paths you use for the request mappings.
Hope this helps.
in my exercise i have to develop a spring application which should be accessible through a WebGUI AND a REST service.
Now i browed through the examples of Spring MVC, there is this hello world tutorial on Spring MVC.
The controller looks like as follows:
#Controller
#RequestMapping("/welcome")
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Hello World");
return "hello";
}
}
Then i looked through the Spring REST example which looks like this:
#Controller
#RequestMapping("/movie")
public class MovieController {
#RequestMapping(value = "/{name}", method = RequestMethod.GET)
public String getMovie(#PathVariable String name, ModelMap model) {
model.addAttribute("movie", name);
return "list";
}
#RequestMapping(value = "/", method = RequestMethod.GET)
public String getDefaultMovie(ModelMap model) {
model.addAttribute("movie", "this is default movie");
return "list";
}
}
Now I am wondering, how do these two examples (Spring-mvc and Spring-rest) differ?
They both use the same annotations and work similar. Aren't that both just REST examples?
How can I provide a Rest-Interface to a Spring-MVC application?
regards
In order to provide rest interface to Spring MVC application, you can apply #RequestMapping annotation with a path name to each of the methods in controller, this creates a unique URL path for each of the rest services you would like to provide.
Meaning, the rest services are nothing but the methods in Spring MVC controller with #RequestMapping annotation.
If you would like to learn how Spring MVC supports Rest Based services, the below link might help:
http://blog.springsource.org/2009/03/08/rest-in-spring-3-mvc/#features
Both samples are about Spring Web MVC.
You should pay more attention to definitions, like what is REST
https://en.wikipedia.org/wiki/Representational_state_transfer
Representational State Transfer is intended to evoke an image of how a
well-designed Web application behaves: presented with a network of Web
pages (a virtual state-machine), the user progresses through an
application by selecting links (state transitions), resulting in the
next page (representing the next state of the application) being
transferred to the user and rendered for their use.
Spring Web MVC greatly facilitates developing REST web APIs and that's it.
Rememeber #ResponseBody as return type on method is going to be REST.
ofcourse returned object can be negotiated with either JSON or XML.
