Im previously wrote the code which save data from form in spring and it worked fine. Now i have tried to wrote the code which get data from android client and save it in mysql database. but in result i have a problem

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'signupController' defined in file

Also i dont understand why i have such problem if i have in dispatcher-servet 

<context:component-scan base-package="com.dubovskiyM.mvc"/>
<context:annotation-config/>

Or can this problem cause because controller and repository situated in differends folders. but in one package com.dubovskiyM.mvc?

My files

Controller 

@Controller
@RequestMapping("/test")
public class SignupController {

private Reg_repository reg_repository;



    @Autowired
 public SignupController(Reg_repository reg_repository) {
     this.reg_repository = reg_repository;
   }

    @RequestMapping(method = RequestMethod.POST)
 public @ResponseBody String signupm(@RequestBody String s){

    Gson  gson = new Gson();
    Signup signup =  gson.fromJson(s,Signup.class);

    return signup.getLogin();}
}

"Only one annotated constructor per-class can be marked as required, but multiple non-required constructors can be annotated. In that case, each is considered among the candidates and Spring uses the greediest constructor whose dependencies can be satisfied, that is the constructor that has the largest number of arguments." per Spring doc

So remove the default constructor and try.

  • No. i have added the default when i have the next mistake org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'signupController' defined in file – Mikhail Apr 20 '14 at 17:53
  • Try @Autowired on private Reg_repository reg_repository; directly instead of passing it in constructor of controller. – Prasad Apr 20 '14 at 18:25
  • thanks, but why this mistake happen? Why in previous project i didnt have and in this i have. What does case this error. – Mikhail Apr 20 '14 at 18:35

    Spring does not resolve proxy type for concrete class Reg_repository. Check this: http://stackoverflow.com/questions/2387431/spring-autowiring-class-vs-interface – Prasad Apr 20 '14 at 21:31
