Postman Request to GET query with Multiple List<String> Parameters - spring

Question

I am trying to test a Multi Module Spring WebMVC API endpoint using Postman. This is Spring-MVC web app & using other frameworks too.
I want to know how to make a request to this URL.
My Controller File looks like this.
#Controller
#RequestMapping(value = "/xyz")
public class XyzWebController {
#CrossOrigin(origins = "*")
#RequestMapping(value = "", method = RequestMethod.GET)
#ResponseBody
public List<XyzChild> getProperties(#RequestParam XyzQueryDTO query) {
return childService.getAll(query);
}
...
}
XyzQueryDTO.java looks like this.
public class XyzQueryDTO {
List<String> properties;
List<String> applications;
public XyzQueryDTO() {
}
public XyzQueryDTO(List<String> properties,
List<String> applications) {
super();
this.properties = properties;
this.applications = applications;
}
...
}
Please assist me with the URL with which i can test this API.
Thanks in Advance.

Answer 1

It's more simple and correct to use RequestMethod.POST instead of RequestMethod.GET and #RequestBody instead of #RequestParam
#RequestMapping(value = "", method = RequestMethod.POST)
#ResponseBody
public List<XyzChild> getProperties(#RequestBody XyzQueryDTO query) {
return childService.getAll(query);
}
And you can use #RestController instead of #Controller and remove #ResponseBody
For data type conversion use jackson librairy.
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.8.8</version>
</dependency>
In Postman you can fill your XyzQueryDTO in the BODY as json
