，优先级越小 @Provider public class RequestLogFilter implements ContainerRequestFilter { @Inject javax.inject.Provider...throws IOException { LogService log = logService.get(); //保存请求日志 } } 看到区别了吧，注入的对象被javax.inject.Provider
dependencies, as an alternative to using * {@link org.springframework.beans.factory.ObjectFactory} or {@link javax.inject.Provider
@Value - 没有相同功能 @Required - 没有相同功能 @Lazy - 没有相同功能 ObjectFactory Provider javax.inject.Provider是Spring
该类实现 javax.inject.Provider 接口，设置 EurekaClientConfig ( Eureka 客户端配置 ) 的生成工厂。
Guice 3.0支持 jdk 1.6, 如果运行报错ClassNotFoundException: javax.inject.Provider, 则需要导入javax.inject包.
descriptor.getDependencyType()) { return new DependencyObjectProvider(descriptor, requestingBeanName); // 3. javax.inject.Provider
leaseInfoBuilder.build()); 105: } 106: return instanceInfo; 107: } 108: 109: } 该类实现 javax.inject.Provider
> javaxInjectProviderClass; static { try { javaxInjectProviderClass = ClassUtils.forName("javax.inject.Provider
Qualifier）可以通过javax.inject.Named来实现 @Value - 不等价 @Required - 不等价 @Lazy - 不等价 ObjectFactory Provider javax.inject.Provider
Provider返回出去~ return new DependencyObjectProvider(descriptor, requestingBeanName); } // 兼容jsr330的javax.inject.Provider
descriptor.getDependencyType()) { return new DependencyObjectProvider(descriptor, requestingBeanName); } // 支持到了javax.inject.Provider
