非controller使用 @Autowired

第一步 加注解

@Component


第二步



    @Autowired
    private IndexService indexService;

    public static rxd rxd;

    @PostConstruct
    public void init() {
        rxd = this;
        rxd.indexService=indexService;
    }

初始化容器
//举例
rxd.indexService.find(map);

//在多线程中无法使用  @Autowired

//代码 


@Service
public class ManageSpringBeans implements ApplicationContextAware {
    private static ApplicationContext context;
 
	public static <T> T getBean(final Class<T> requiredType) {
		return context.getBean(requiredType);
	}
 
	public static <T> T getBean(final String beanName) {
		@SuppressWarnings("unchecked")
		final T bean = (T) context.getBean(beanName);
		return bean;
	}
 
	public static <T> Map<String, T> getBeans(final Class<T> requiredType) {
		return context.getBeansOfType(requiredType);
	}
 
	public static Map<String, Object> getBeansWithAnnotation(final Class<? extends Annotation> annotationType) {
		return context.getBeansWithAnnotation(annotationType);
	}
 
	@Override
	public void setApplicationContext(final ApplicationContext applicationContext) {
		context = applicationContext;
	}
}



//之后在业务层  获取bean

  IndexService indexService = ManageSpringBeans.getBean("indexServiceImp");

int sava = indexService.sava();


//需要注意的是 indexServiceImp  , 获取的是@Service注解下的bean ,而并不是接口！
