自动装配不适用于 org.springframework.boot.autoconfigure.jms.artemis.ArtemisProperties

Question

我正在尝试在 SpringBoot 应用程序中使用的库中自动装配 org.springframework.boot.autoconfigure.jms.artemis.ArtemisProperties，但出现无法找到 bean 类型的错误。在构建期间，我没有遇到任何问题。

我想从 ArtemisProperties class 中检索一些值的库。该库中的 pom.xml 导入 artemis 库。

在库中，我有一个 class，我想在其中获取 Artemis 尝试连接的主机的一些值

package com.xxx.ems.microservice.core.queue;

import java.util.regex.PatternSyntaxException;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.jms.artemis.ArtemisProperties;
import org.springframework.jms.annotation.EnableJms;
import org.springframework.stereotype.Component;

import com.xxx.ems.microservice.core.queue.MessageDispatcherConfiguration.DispatchInfo;

import co.elastic.apm.api.CaptureSpan;
import lombok.extern.slf4j.Slf4j;

// Message Dispatcher
@Component
@EnableJms
@Slf4j
public class MessageDispatcher {
    @Autowired
    MessageDispatcherConfiguration messageDispatcherConfiguration;

    @Autowired
    MessageSender messageSender;

   @Autowired
   private ArtemisProperties artemisProperties;



    private void sendFile(DispatchInfo dispatcheInfo, MessageInformationExtractor messageInformationExtractorForDispatch, EMSFileMessage emsFileMessage, int ... priority) throws EMSQueueException{
        if (hasToBeSend(dispatcheInfo, messageInformationExtractorForDispatch, emsFileMessage)){
            for (String destinationQueue:dispatcheInfo.getDestinationQueueNames()){ 
                log.debug("Will send {} to {}:{}  and queue {}", emsFileMessage.getId(), artemisProperties.getHost(), artemisProperties.getPort(), destinationQueue);
                messageSender.send(destinationQueue, emsFileMessage, priority); 
            } ;
        }
    }
....

在我的 spring-boot 应用程序 pom.xml 中，我将依赖项包含在库中，并且我将 classes 的组件扫描包含在库中：

package com.xxx.ems.microservice.msdiskloader;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableAsync;

import com.xxx.ems.microservice.core.app.EMSMicroserviceApplication;

@SpringBootApplication
@ComponentScan("com.xxx.ems")
@Configuration  
@EnableAsync 
public class MSDiskLoaderApplication extends EMSMicroserviceApplication{

    public static void main(String[] args) {
        EMSMicroserviceApplication.run(MSDiskLoaderApplication.class, args);
    }

}

知道为什么我有这个自动装配错误吗？已正确添加来自 artemis 库的依赖项。可能与其他图书馆不兼容吗？

完整错误如下

**************************
APPLICATION FAILED TO START
***************************

Description:

Field artemisProperties in com.xxx.ems.microservice.core.queue.MessageDispatcher required a bean of type 'org.springframework.boot.autoconfigure.jms.artemis.ArtemisProperties' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'org.springframework.boot.autoconfigure.jms.artemis.ArtemisProperties' in your configuration.

谢谢

Answer 1

First create a bean of ArtemisProperties and set properties in it and then you can autowired it. 
@Bean 
public ArtemisProperties artemisProperties () { 
ArtemisProperties artemisObj = new ArtemisProperties(); 
return artemisObj; 
} 

@Autowired private ArtemisProperties artemis;
------------------------------------------------------------------------

Answer 2

@ConfigurationProperties 和自动配置不是 public API，因此我强烈建议您不要在自己的代码中使用它。这个bean是自动配置创建的，如果你的自定义代码让它后退，它就不会再创建了。

@EnableConfigurationProperties(ArtemisProperties.class) 是确保它在上下文中注册并绑定到环境的最佳方法。

自动装配不适用于 org.springframework.boot.autoconfigure.jms.artemis.ArtemisProperties

Autowire not working with org.springframework.boot.autoconfigure.jms.artemis.ArtemisProperties
