I am attempting to autowire a repository into one of my classes but I cannot get it to work and it has been driving me crazy for the past couple days. NOTE: The program will run and the autowiring of person import will work if I comment out the @Autowire on personRepository inside the personImport class so I know the problem lies with the autowiring of PersonRepository. Here are my classes...
APPLICATION CONTEXT.XML
When i attempt to run the program, it gives me this error (a lot of it had to be omitted to allow it to be posted)
Code:
package com.mycompany.springwork;

import org.springframework.web.bind.annotation.RequestMethod;
/**

*/
@Controller
public class HomeController {
@Autowired
PersonImport personImport;
@RequestMapping(value = "/", method = RequestMethod.GET)
public String Home()
{
personImport.doImportPerson("anthony");
return "index";
}
