spring 云 aws 注释驱动的队列侦听器

Question

我正在尝试使用 spring 云 AWS 注释驱动的队列侦听器编写一个使用 AWS SQS 的 Web 应用程序，我的代码如下所示：

XML AWS Beans：

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aws-context="http://www.springframework.org/schema/cloud/aws/context"
       xmlns:aws-messaging="http://www.springframework.org/schema/cloud/aws/messaging"
       xmlns="http://www.springframework.org/schema/beans"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
  http://www.springframework.org/schema/beans/spring-beans.xsd
  http://www.springframework.org/schema/cloud/aws/context
  http://www.springframework.org/schema/cloud/aws/context/spring-cloud-aws-context.xsd
  http://www.springframework.org/schema/cloud/aws/messaging
     http://www.springframework.org/schema/cloud/aws/messaging/spring-cloud-aws-messaging">

    <!-- Define global credentials for all the AWS clients -->
    <aws-context:context-credentials>
        <aws-context:instance-profile-credentials/>
        <aws-context:simple-credentials access-key="${accessKey:}"
                                        secret-key="${secretKey:}"/>
    </aws-context:context-credentials>

    <!-- Define global region -->
    <aws-context:context-region region="EU_WEST_1"/>

    <!-- Cloud Formation Stack -->
    <aws-context:stack-configuration stack-name="StackName"/>
    <aws-messaging:annotation-driven-queue-listener />
</beans>

然后我写了这个 class，它有一个带有 SqsListener 注释的方法，它向控制台打印 hello :

package com.example.demo;

import org.springframework.cloud.aws.messaging.listener.annotation.SqsListener;

public class AWSSQSListner {

    @SqsListener("queue-name")
    public void queueListener(Person person) {
        System.out.print("\"Hello\"");
    }
}

这是我的 gradle 构建文件：

Gradle build file:

    buildscript {
    ext {
        springBootVersion = '2.0.5.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


ext {
    springCloudVersion = 'Finchley.SR1'
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-web-services')
    compile('org.springframework.cloud:spring-cloud-starter-aws')
    compile('org.springframework.cloud:spring-cloud-starter-aws-messaging')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}

但是当我运行应用程序没有发生任何事情时，我是 java 和 spring 引导的新手，我有什么地方做错了吗

Answer 1

我只需要将 @Component 注释添加到 AWSSQSListner class 就可以了，也不需要 XML AWS bean

spring 云 aws 注释驱动的队列侦听器

spring cloud aws annotation driven queue listener

spring

spring-cloud
