非controller类调用spring框架的service

1、在使用spring-mvc框架的时候经常会遇到在非controller类里面调用service方法，service类使用的是注解，如果直接调用的话会出现service为null

private static UserAppService service;// 用户服务类

@Autowired
public void setService(UserAppService service) {
    GoalControlRule.service = service;
}

注方法类型加：@Component注解
例如：

@Component
public class GoalControlRule {
private static UserAppService service;// 用户服务类
@Autowired
public void setService(UserAppService service) {
GoalControlRule.service = service;
}
private static BasicArchivesPlatformService basicArchivesPlatformService;//基础档案平台服务类
@Autowired
public void setBasicArchivesPlatformService(BasicArchivesPlatformService basicArchivesPlatformService) {
GoalControlRule.basicArchivesPlatformService = basicArchivesPlatformService;
}
}
2、main方法中调用spring持久层service或dao

private static ApplicationContext ac = new ClassPathXmlApplicationContext(“applicationContext.xml”);
private static UserPlatformService userPlatformService = (UserPlatformService) ac.getBean(“userPlatformService”);
public static void main(String[] args) {
System.out.println(userPlatformService.getPatientInfo(“2489”));
}
