NoSuchBeanDefinitionException：无型的排位豆的内部类

Question

我尝试过第三方bean添加到我的应用程序：

@Configuration 
@ComponentScan(...) 
public class ApplicationConfiguration { 

    @Bean(name = "mqSocket") 
    public ZMQ.Socket startServer() { 
     try (ZMQ.Context ctx = ZMQ.context(1); 
      ZMQ.Socket publisher = ctx.socket(ZMQ.PUB)) { 
      publisher.bind("tcp://*:5556"); 
      return publisher; 
     } 
    } 
} 

，我尝试自动装配这个是这样的：

@RestController 
public class MyRestController {  

    @Autowired 
    private ZMQ.Socket mqSocket; 

但打印以下：

java.lang.IllegalStateException: Failed to load ApplicationContext 
... 
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'myRestController': Unsatisfied dependency expressed through field 'mqSocket'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.zeromq.ZMQ$Socket' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 
...

Answer 1

你应该像你的类应用程序添加@Import annotation。

例如：

@Import(ApplicationConfiguration.class) 
public class Application { 

} 

注：参见@ M.Prokhorov评论道，ZMQ.Socket由资源尝试声明关闭

Answer 2

您创建了名mqSocket一个bean，所以我想你必须使用@Qualifier注释;试图改变这样的代码：

@RestController 
public class MyRestController {  

    @Autowired 
    @Qualifier("mqSocket") 
    private ZMQ.Socket mqSocket; 

我希望这是有用的
