I want to get io.swagger.models.Swagger object in my system, which is a restful backend based on jersey and swagger.
I saw in class ApiListingResource there is such a statement
Swagger swagger = (Swagger) context.getAttribute("swagger");
, which can retrieve the swagger object from servlet context.
Can I do the same in my own code? This seems not a contract that the attribute name will always be "swagger". So I dare not.
Is there any reliable way to retrieve the object?
You can rely on the context (yes, it is set to the name swagger, or with your own logic by extending BeanConfig

I am writing a custom OpenApiConfigurator that adds some examples to my api dynamically.
When I add the examples using the value field of io.smallrye.openapi.api.models.examples.ExampleImpl, which is an object, the example is null in swagger-ui. It only works when I added the actual json.
To add the actual json I have to generate it from my response dto using Jackson. But how can I access the quarkus object mapper, for which I have some customisations using ObjectMapperCustomizer, if in the OpenApiConfigurator CDI is not available?
It's actually possible to access the CDI container statically with Arc.container().instance(ObjectMapper::class.java).get()
That solved it for me.
I have the bellow apis in my application. My application manages spring security and in the logic there are some rules like based on the user's role , the user might be able to see or not certain attributes.
So my requirement it is to make null some attributes of the CustomObject based on the user's role.
Is there a way to accomplish this based with Spring Security ? There is the #PostFilter annotation but I think it will be useful to discard objects in the method's response , but not to make some attributes of the object null
public List<CustomObject> getCustomObjects()
public CustomObject getCustomObject()
If this is not possible with only spring security, I am thinking to create a custom annotation , mixed with some AOP to do the work, what do you think ?
Some one please me to find out the spring mvc examples,
Because usually, once we log in into the application we will create a session and put some objects into session . we will access later point of time , request scope as well. but spring MVC3 is difficult to understand even documentation also confusing, but every one giving example is basic examples only.
You can access these objects in a JSP/JSTL:
applicationScope
cookie
header
headerValues
initParam
pageContext
pageScope
param
paramValues
requestScope
sessionScope
As well as any request attributes that you add, including model attributes (who's default name is command).
More info here: http://www.informit.com/articles/article.aspx?p=30946&seqNum=7
If you want to access HttpRequest, HttpResponse, HttpSession, add them as arguments to a Spring Controller Handler Method . Spring will pass them in for you.
I have a Spring MVC application which returns Json and Xml based on what is requested per client call. I am using Jackson and Xstream to let Spring do the de-serialization of my java object into json or xml output.
My java object contains a bunch of attributes, at least 30. I would like to know if there is a way I can let Spring control which fields of my java object will be present in the json or xml based on a header or parameter attribute. So the client application will be able to identify itself and the backend will return only the fields necessary or "visible" for that specific client app. Of course I could go to the nasty approach of hard coding, but I would not like to do that as the number of client applications can increase or decrease and having a deployment anytime it happens with code changes is out of context.
Is there a way to instruct spring/jackson/xstream to control the output based on some providaded value?
I did a quick implementation and my current solution works like this: I have an xml with a list of client IDs (I use these ids to identify my client app) and for each ID I have a list of attributes that the client app needs from the java object. I created a interceptor and between the controller and the view, my interceptor gets the header information with the client ID, get the list of attributes and using the BeanWrapper (http://docs.spring.io/spring/docs/2.0.x/reference/validation.html) to create a new object with only the attributes required by the client with data, all the others remain null (I instruct Jackson and Xtream) to ignore null attributes. This approach works fine but I was wondering if there is another/better way to do this.
Thank you

I want to use Spring MVC 3.0 to build interfaces for AJAX transactions. I want the results to be returned as JSON, but I don't necessarily want the web pages to be built with JSP. I only want requests to the controllers to be intercepted/routed through the DispatcherServlet and the rest of the project to continue to function like a regular Java webapp without Spring integration.
My thought was to define the servlet-mapping url pattern in web.xml as being something like "/controller/*", then have the class level #RequestMapping in my controller to be something like #RequestMapping("/controller/colors"), and finally at the method level, have #RequestMapping(value = "/controller/colors/{name}", method = RequestMethod.GET).
Only problem is, I'm not sure if I need to keep adding "/controller" in all of the RequestMappings and no matter what combo I try, I keep getting 404 requested resource not available errors.
The ultimate goal here is for me to be able to type in a web browser "http://localhost:8080/myproject/controller/colors/red" and get back the RGB value as a JSON string.
You are not correct about needing to add the entire path everywhere, the paths are cumulative-
If you have a servlet mapping of /controller/* for the Spring's DispatcherServlet, then any call to /controller/* will be handled now by the DispatcherServlet, you just have to take care of rest of the path info in your #RequestMapping, so your controller can be
#Controller
#RequestMapping("/colors")
public class MyController{
#RequestMapping("/{name}
public String myMappedMethod(#PathVariable("name") String name, ..){
}
}
So now, this method will be handled by the call to /controller/colors/blue etc.
I don't necessarily want the web pages to be built with JSP
Spring MVC offers many view template integration options, from passthrough to raw html to rich templating engines like Velocity and Freemarker. Perhaps one of those options will fit what you're looking for.
