spring-boot-starter-amqp依賴性原因StackOverflowError

Question

我有一個基本的Spring Boot項目，我試圖用RabbitMQ實現簡單的消息傳遞。當我添加彈簧引導起動AMQP依賴到我pom.xml文件，並開始春季啓動應用程序時，我得到java.lang.reflect.InvocationTargetException異常引起java.lang.StackOverflowError：

如果我從pom.xml刪除spring-boot-starter-amqp依賴項，該項目可正常工作：

<dependency> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-amqp</artifactId> 
</dependency> 

Answer 1

我不確定它會解決你的問題，但你有反正潛在的衝突，因爲根據日誌你拉log4J依賴。
如果你這樣做，你要排除默認情況下提供的logback當你你聲明：

<dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-web</artifactId> 
    </dependency> 

您可以通過顯示你的項目的依賴關係樹，並通過查找org.springframework.boot:spring-boot-starter-web:jar依賴翻出什麼檢查：

[INFO] +- org.springframework.boot:spring-boot-starter-web:jar:1.4.0.RELEASE:compile 
[INFO] | +- org.springframework.boot:spring-boot-starter:jar:1.4.0.RELEASE:compile 
[INFO] | | +- org.springframework.boot:spring-boot-starter-logging:jar:1.4.0.RELEASE:compile 
[INFO] | | | +- ch.qos.logback:logback-classic:jar:1.1.7:compile 
[INFO] | | | | +- ch.qos.logback:logback-core:jar:1.1.7:compile 
[INFO] | | | | \- org.slf4j:slf4j-api:jar:1.7.21:compile

[INFO] | | | \- org.slf4j:log4j-over-slf4j:jar:1.7.21:compile 
[INFO] | | \- org.yaml:snakeyaml:jar:1.17:runtime 

Spring Boot指出，如果它在類路徑上，它支持Log4j 2用於日誌記錄配置。如果您使用starters來組裝依賴關係，那意味着您必須排除Logback，然後包含log4j 2。

所以只使用log4j的，你可以從彈簧引導啓動，網絡依賴排除的logback：

<dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-web</artifactId> 
     <exclusions> 
      <exclusion> 
       <groupId>org.springframework.boot</groupId> 
       <artifactId>spring-boot-starter-logging</artifactId> 
      </exclusion> 
     </exclusions> 
    </dependency> 

或僅的logback使用，則應排除可能是宣佈你的其他的一扣的log4j依賴。
使用方法：mvn dependency:tree從Maven項目中知道的罪魁禍首。

但無論如何，你不應該同時使用兩者。

Answer 2

如果您的意圖是通過RabbitMQ使用AMQP，請刪除所有JMS依賴項。

另外，對於一個簡單的應用程序，您也不需要Spring集成。嘗試只使用你的應用程序spring-boot-starter-amqp
