我正在尝试使用Spring Boot和Spring Cloud AWS SQS构建最小的Gradle Java项目，但无法从队列中读取它。

这些是我的项目文件：

build.gradle：

apply plugin: "java"
apply plugin: "eclipse"
apply plugin: "spring-boot"
apply plugin: "io.spring.dependency-management"

sourceCompatibility = 1.8
targetCompatibility = 1.8

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.5.RELEASE")
        classpath("io.spring.gradle:dependency-management-plugin:0.5.2.RELEASE")
    }
}

dependencyManagement {
     imports {
          mavenBom("org.springframework.cloud:spring-cloud-aws:1.1.0.RELEASE")
     }
}

repositories {
    mavenCentral()
}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-actuator:1.3.5.RELEASE")
    compile("org.springframework.cloud:spring-cloud-starter-aws:1.1.0.RELEASE")
    // if I don't add the line below, the annotation @MessageMapping is not found :(
    // I would have expected that cloud-starter-aws would have taken care of it
    compile("org.springframework.cloud:spring-cloud-aws-messaging:1.1.0.RELEASE")
    // this has been added to fix an exception happening, please read below
    compile("org.springframework.data:spring-data-commons:1.12.1.RELEASE")
}

Application.java：

package com.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application
{    
    public static void main(String[] args)
    {
        SpringApplication.run(Application.class, args);
    }
}

QueueListener.java：

package com.test.sqs;

import java.util.logging.Logger;
import org.springframework.messaging.handler.annotation.MessageMapping;
import com.test.sqs.model.TestMessage;

public class QueueListener
{
    @MessageMapping("test_queue")
    private void receiveMessage(TestMessage testMessage)
    {
        System.out.println("Test message received: " + testMessage.getMessage());
    }
}

src / main / resources中的application.yaml：

cloud:
    aws:
        credentials:
            accessKey: **********************
            secretKey: **********************
        region:
            static: us-west-2

应用程序在启动时会引发异常（但是您可以在日志调试模式下看到该异常！）：

org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.amazonaws.auth.profile.ProfilesConfigFile]: Constructor threw exception; nested exception is java.lang.IllegalArgumentException: AWS credential profiles file not found in the given path: C:\src\collector\default

但我总是在日志中看到它确实从yaml文件中提取了我的凭据：

2016-05-19 11:15:14.546 DEBUG 11704 --- [           main] o.s.c.e.PropertySourcesPropertyResolver  : Searching for key 'cloud.aws.credentials.accessKey' in [systemProperties]

因此，我不确定为什么会在其他地方查看？

它还引发此异常（仅当您处于记录调试模式时，才总是可见）：

    java.lang.ClassNotFoundException: org.springframework.data.web.config.EnableSpringDataWebSupport

所以我不得不添加build.gradle

compile("org.springframework.data:spring-data-commons:1.12.1.RELEASE")

但是现在例外不再存在了，但是程序不执行任何操作就开始和结束了，并且不再打印日志了！

其他一些事实：

• Application.java位于正确的程序包中，以使组件能够正常工作，因此Spring应该看到QueueListener类，
• 正确读取了application.yaml，如果它在错误的区域中抱怨，
• 如果我输入了错误的凭证（错误的accessKey或/和错误的secretKey），它不会抱怨，因此我认为它根本没有尝试连接到AWS。

我不确定build.gradle的第34行：

compile("org.springframework.cloud:spring-cloud-starter-aws:1.1.0.RELEASE")
// if I don't add the line below, the annotation @MessageMapping is not found :(
// I would have expected that cloud-starter-aws would have taken care of it
compile("org.springframework.cloud:spring-cloud-aws-messaging:1.1.0.RELEASE")
// this has been added to fix an exception happening, please read below
compile("org.springframework.data:spring-data-commons:1.12.1.RELEASE")

可能是问题的征兆，我希望所有需要的库都可以由cloud-starter-aws自动加载。

我想念什么？谢谢！
