代码中嵌套bean的引用，我用@Resource(type=CouponServiceImpl.class)
private CouponService couponService;
或者使用
@Resource(name="couponService")
private CouponService couponService;
或者使用
@Resource
private CouponService couponService;
的时候启动报如下错：Error creating bean with name 'couponService': Bean with name 'couponService' has been injected into other beans [orderManagerServiceImpl,withdrawServiceImpl,orderServiceHelper,orderService,xmOrderServiceImpl,distributeProfitServiceImpl,distributeProfitHelper,distributeListenerImpl] in its raw version as part of a circular reference, but has eventually been wrapped. This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesOfType' with the 'allowEagerInit' flag turned off, for example.
用@Autowired就完全正常。 求大神帮忙解释一下，完全不懂
