大佬教程收集整理的这篇文章主要介绍了Spring Boot,Spring Cloud AWS和AWS SQS未从队列读取,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
发现了问题,这当然是愚蠢的。
Spring没有加载QueueListener类,因为它没有service / Component批注,因此:
@service
public class SqsQueueSender
{
...
}
解决了这个问题。
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 @@R_450_8798@geMapping is not found :(
// I would have expected that cloud-starter-aws would have taken care of it
compile("org.springframework.cloud:spring-cloud-aws-@R_450_8798@ging: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.@R_450_8798@ging.handler.Annotation.@R_450_8798@geMapping;
import com.test.sqs.model.Test@R_450_8798@ge;
public class QueueListener
{
@@R_450_8798@geMapping("test_queue")
private void receive@R_450_8798@ge(Test@R_450_8798@ge test@R_450_8798@gE)
{
System.out.println("Test @R_450_8798@ge received: " + test@R_450_8798@ge.get@R_450_8798@ge());
}
}
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]
2016-05-19 11:15:14.546 DEBUG 11704 --- [ main] o.s.c.e.PropertysourcesPropertyResolver : Searching for key 'cloud.aws.credentials.accessKey' in [systemEnvironment]

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:
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 @@R_450_8798@geMapping is not found :(
// I would have expected that cloud-starter-aws would have taken care of it
compile("org.springframework.cloud:spring-cloud-aws-@R_450_8798@ging: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!
