Question

我正在尝试新的Spring-boot 2.0.0.M1。我使用https://start.spring.io/初始化项目，只选择Web依赖项。

我在eclipse中打开了这个生成的项目，我在运行mvn clean install时遇到了错误：

    Exception in thread "main" java.lang.IllegalArgumentException: Cannot instantiate interface org.springframework.boot.SpringApplicationRunListener : org.springframework.boot.context.event.EventPublishingRunListener

有没有人面临过类似的问题？请帮忙。

Answer 1

AutoProxyUtils类可用于org.springframework.aop.framework.autoproxy包而不是org.springframework.aop.framework包。检查classpath中是否提供了正确版本的spring-aop库。但是，它似乎是框架的错误。

我还有另外一项工作，

将spring-aop从启动依赖项中排除，如

<?php
    $url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
    if (strpos($url,'pages') !== false) {
        $url = trim($url, '%');
    }
?>

并使用新版本

分别添加spring-aop

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-aop</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

Answer 2

我遇到了同样的问题，我从.m2（Maven存储库）中删除了springaop文件夹并构建它。现在工作正常

Answer 3

我在Spring Boot 1.5.4.RELEASE项目中遇到了同样的问题。我在项目中使用Amazon S3依赖项。我按照上述步骤进行操作，并提供了排除项，并添加了aop依赖关系，但未能解决问题。当我将spring boot版本从1.5.4.RELEASE更改为1.5.6.RELEASE时，它已解决。

Answer 4

在pom.xml中包含spring-aop依赖项

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aop</artifactId>
    <version>5.0.1.RELEASE</version>
</dependency>

Spring Boot 2.0.0.M1错误引起：java.lang.ClassNotFoundException：org.springframework.aop.framework.AopProxyUtils
