spring can't receive post param send by postman - spring-boot

Question

And My Controller is like
#RequestMapping(value = "/auth/company/delete", method = RequestMethod.POST,
produces = {"application/json", "application/xml"})
#ResponseBody
public ResponseMessage deleteCompany(#RequestParam("companyId") Integer companyId) {
return companyManageService.deleteCompany(companyId);
}
But when I type code in chrome console using
$.post( "http://ltc_dev.leapstack.cn/gw/security/auth/company/delete", { companyId: 1 })
.done(function( data ) {
alert( data.success);
alert( data.message);
});
I got correct response, so.....
I'm not sure if it is a postman's bug, or I cofig the controller wrong

Answer 1

In your question, your controller method try to take companyId as request param. In postman you are sending companyId in request body. Like I said in comment you can send request param in url section directly like that: /auth/company/delete?companyId=2. Spring boot can detect companyId request parameter and assign it to method's companyId variable directly.
If you want to send companyId in request body (You said that in comment) you have to change your method's signature like below.
#RequestMapping(value = "/auth/company/delete", method = RequestMethod.POST, produces = {"application/json", "application/xml"})
#ResponseBody
public ResponseMessage deleteCompany(#RequestBody Map<String, Integer> map) {
return companyManageService.deleteCompany(map.get("companyId"));
}
Or:
#RequestMapping(value = "/auth/company/delete", method = RequestMethod.POST, produces = {"application/json", "application/xml"})
#ResponseBody
public ResponseMessage deleteCompany(#RequestBody CompanyDTO company) {
return companyManageService.deleteCompany(company.getCompanyId);
}
public class CompanyDTO {
private Integer companyId;
//getter setter
}
If you want to use request body and want to catch integer value directly in controller method's variable as integer your request body should be like:
{2}
And controller method should be like:
#RequestMapping(value = "/auth/company/delete", method = RequestMethod.POST, produces = {"application/json", "application/xml"})
#ResponseBody
public ResponseMessage deleteCompany(#RequestBody Integer companyId) {
return companyManageService.deleteCompany(companyId);
}
