当我尝试运行基于Spring的Web应用程序时，我可以看到它。我阅读了一些文章，我可以理解，当您使用不同版本的依赖项时，可能会出现此问题。在我的应用程序中，我使用Spring 4.0.1版本和Spring-Security仅3.2.5，因为它不是最新版本。如果我的问题构成了这件事，请告诉我我能做什么。

Answer 1

Spring 4具有新的物料清单（BOM）功能，可以简化依赖关系管理。您可以尝试尝试解决版本冲突问题。

Answer 2

在使用swagger-webmvc 1.0.1时，将spring依赖项从3.2.9更新到4.0.9时出现了同样的错误。我需要从swagger手动排除spring-webmvc和spring-web依赖项，并强制使用版本4.0.9的spring库。定义这看起来像依赖冲突...

Answer 3

就我而言，我正在使用1.5.1.RELEASE版本的springboot应用程序。添加Swagger2依赖关系后，我的构建就被破坏了，因为swagger依赖关系使用的是spring-beans较少的版本。

当我添加排除项时，我的问题就解决了。

例如：

<dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.9.2</version>
        <scope>compile</scope>
        <exclusions>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-beans</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
