[英]NoSuchBeanDefinitionException: No qualifying bean of type (repository)
[英]NoSuchBeanDefinitionException: No qualifying bean of type for inner class
我尝试将第三方 bean 添加到我的应用程序中:
@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;
}
}
}
我尝试像这样自动装配:
@RestController
public class MyRestController {
@Autowired
private ZMQ.Socket mqSocket;
但它打印以下内容:
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$Socket' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
...
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.zeromq.ZMQ$Socket' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
...
您应该在您的应用程序类上添加@Import
注释。
例如。:
@Import(ApplicationConfiguration.class)
public class Application {
}
注:参见 @M.Prokhorov 评论, ZMQ.Socket
被 try-with-resource 语句关闭
您创建了一个名为 mqSocket 的 bean,所以我猜您必须使用@Qualifier
注释; 尝试以这种方式更改您的代码:
@RestController
public class MyRestController {
@Autowired
@Qualifier("mqSocket")
private ZMQ.Socket mqSocket;
我希望它有用
