BaseRepository.java:
1 package com.hk.beans.generic.di;2 3 public class BaseRepository{4 5 }
BaseService.java:
1 package com.hk.beans.generic.di; 2 3 import org.springframework.beans.factory.annotation.Autowired; 4 5 public class BaseService{ 6 7 @Autowired 8 protected BaseRepository repository; 9 10 public void add(){11 System.out.println("add...");12 System.out.println(repository);13 }14 }
User.java:
1 package com.hk.beans.generic.di;2 3 public class User {4 5 }
UserRepository.java:
1 package com.hk.beans.generic.di;2 3 import org.springframework.stereotype.Repository;4 5 @Repository6 public class UserRepository extends BaseRepository{7 8 }
UserService.java:
1 package com.hk.beans.generic.di;2 3 import org.springframework.stereotype.Service;4 5 @Service6 public class UserService extends BaseService{7 8 }
Main.java:
1 package com.hk.beans.generic.di; 2 3 import org.springframework.context.ApplicationContext; 4 import org.springframework.context.support.ClassPathXmlApplicationContext; 5 6 public class Main { 7 public static void main(String[] args) { 8 ApplicationContext ctx = new ClassPathXmlApplicationContext("beans-generic-di.xml"); 9 UserService userService = (UserService) ctx.getBean("userService");10 userService.add();11 }12 13 }
