Spring集成与Spring引导不兼容

Question

我有一个pom.xml：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.12.RELEASE</version>
    </parent>

    <groupId>com.example</groupId>
    <artifactId>example-app</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <properties>
        <java.version>1.8</java.version>
        <paho.version>1.2.5</paho.version>
    </properties>

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

        <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-jmx</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-mqtt</artifactId>
        </dependency>

        <dependency>
            <groupId>org.eclipse.paho</groupId>
            <artifactId>org.eclipse.paho.mqttv5.client</artifactId>
            <version>${paho.version}</version>
        </dependency>
    </dependencies>

</project>

我得到了一个错误：

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.springframework.integration.config.DefaultConfiguringBeanFactoryPostProcessor.registerErrorChannel(DefaultConfiguringBeanFactoryPostProcessor.java:210)

The following method did not exist:

    'org.springframework.beans.factory.support.BeanDefinitionBuilder org.springframework.beans.factory.support.BeanDefinitionBuilder.rootBeanDefinition(java.lang.Class, java.util.function.Supplier)'

The method's class, org.springframework.beans.factory.support.BeanDefinitionBuilder, is available from the following locations:

    jar:file:/Users/user/.m2/repository/org/springframework/spring-beans/5.2.15.RELEASE/spring-beans-5.2.15.RELEASE.jar!/org/springframework/beans/factory/support/BeanDefinitionBuilder.class

The class hierarchy was loaded from the following locations:

    org.springframework.beans.factory.support.BeanDefinitionBuilder: file:/Users/user/.m2/repository/org/springframework/spring-beans/5.2.15.RELEASE/spring-beans-5.2.15.RELEASE.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.beans.factory.support.BeanDefinitionBuilder

我真的不知道哪种版本的spring引导父版本和spring引导集成将使这一工作。

谢谢!

编辑：

我将pom.xml更改为使用spring的2.3.12.RELEASE版本，并删除了spring-integration-mqtt的version标记，但仍然存在相同的错误。

在执行mvn dependency:tree -Dincludes="org.springframework:spring-beans"时，我有下面的依赖树

[INFO] --- maven-dependency-plugin:3.1.2:tree (default-cli) @ example-app ---
[INFO] com.example:example-app:jar:0.0.1-SNAPSHOT
[INFO] \- org.springframework.boot:spring-boot-starter-web:jar:2.3.12.RELEASE:compile
[INFO]    \- org.springframework:spring-web:jar:5.2.15.RELEASE:compile
[INFO]       \- org.springframework:spring-beans:jar:5.2.15.RELEASE:compile

Answer 1

Spring版本的2.3.x暂时不支持了：https://spring.io/projects/spring-boot#support。

考虑选择最新版本并依靠Spring本身的依赖关系管理:不要对那些可以从Spring借用依赖项的依赖项使用显式版本。

无论如何，org.eclipse.paho.mqttv5.client将无法使用那个旧的Spring版本。您必须至少使用Spring 2.6.8来提取Spring 5.5.12。
