Java Springboot无法通过自动连线注释初始化和注入第三方bean

Description:
Field queue in com.example.taskgenerator.Sender required a bean of type 'org.springframework.amqp.core.Queue' that could not be found.
Action:
Consider defining a bean of type 'org.springframework.amqp.core.Queue' in your configuration.
我第一次将springboot与RabbitMQ一起使用,这是一个队列服务sdk
package com.example.taskgenerator;
import org.springframework.amqp.core.Queue;
@Configuration
public class TaskGeneratorConfig {
@Bean
public Queue queue() {
return new Queue("simple-queue");
}
}
队列是发送方类的依赖项
package com.example.taskgenerator;
import org.springframework.amqp.core.Queue;
@Component
public class Sender {
@Autowired
private Queue queue;
}
请帮忙
编辑:
添加我的主类:
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Profile;
@SpringBootApplication
//@EnableScheduling
//@EnableAsync
public class FileDumpReaderApplication {
@Profile("usage_message")
@Bean
public CommandLineRunner usage() {
return new CommandLineRunner() {
@Override
public void run(String... args) throws Exception {
System.out.println("This app uses Spring profiles to control its behaviour.");
System.out.println("Sample usage : java -jar readerapp.jar --spring.profiles.active=hello_world,sender");
}
};
}
@Profile("!usage_message")
@Bean
public CommandLineRunner usageTwo() {
return new AppRunner();
}
public static void main(String[] args) {
SpringApplication.run(FileDumpReaderApplication.class, args);
}
}
和命令行运行程序类:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.context.ConfigurableApplicationContext;
public class AppRunner implements CommandLineRunner {
@Autowired
private ConfigurableApplicationContext context;
@Autowired
private Sender sender;
@Override
public void run(String... args) throws Exception {
sender.send();
//context.close();
}
}
注意:所有类都在同一个包中。扫描您的包--@SpringBootApplication(scanBasePackages={“com.example.taskgenerator”})并在AppRunner类上给出注释(@Component)
您必须扫描您的包,以便在应用程序启动时它们成为ApplicationContext的一部分。您可能没有spring boot starter web依赖项,并且您的主类在哪里?发布您的主类。在此处查看如何使用RabbitMQ设置spring boot谢谢您的回复。这是我的主要课程:@Adya它不是一个web应用程序。即使不是web项目,我也应该添加此依赖项吗?请澄清。但之前它运行良好。
