Spring启动运行错误

Question

项目Spring引导1..5.7版本。我正在使用Intellij IDEA 2017.2.4和gradle进行依赖性管理。当我构建项目时，它成功构建，没有错误。当我用bootRun gradle任务运行应用程序时，它显示以下错误。

Answer 1

老问题，但是在将Spring应用程序转换为Spring Boot后，我遇到了同样的错误。使用 spring-boot-starter-aop 而不是直接依赖于特定版本的 spring-aop 为我解决了这个问题，例如在 build.gradle 中：

plugins {

    id 'org.springframework.boot' version '1.5.17.RELEASE'
}

apply plugin: 'io.spring.dependency-management'

dependencies {

    compile 'org.springframework.boot:spring-boot-starter-aop' 

}

代替

dependencies {

    compile 'org.springframework:spring-aop:4.2.4.RELEASE'
}

Answer 2

看起来 spring-aop 与您的其他库不匹配。尝试运行 gradle 依赖项并检查所有 Spring 依赖项是否处于同一版本中。有关检查依赖项的更多信息，请参阅 Gradle 用户手册。

Answer 3

正如上面提到的，这似乎是Spring中的一个依赖问题。最简单的方法是检查你的POM文件。
