springBoot bean注入

Posted 2020-09-25 N神3

1、@Component：把普通pojo实例化到spring容器中，相当于配置文件中的<bean id="" class=""/>

2、@Autowired：Spring框架中进行对象注入

@Component
public class Person  {
  private String id;
  private String name;
  private String sex;
  //getter/setter省略
}


@Service
public class personService{
 @Autowired
 Person person;
 //方法省略
}
