【问题讨论】：

你是如何构建它的？
使用 Maven 清理和安装
什么是 pom.xml？
@RomanC 在我的 pom.xml 中 codepile.net/pile/nZbp6o9x
在问题中添加代码。

标签： java spring-mvc spring-security spring-data spring-validation

【解决方案1】：

有类似的问题

意识到问题出在我的 Pom 文件中

我一起添加了 2 个依赖项，而 我必须只使用其中一个

        <dependency>
           <groupId>org.springframework</groupId>
           <artifactId>spring-web</artifactId>
           <version>5.3.20</version>
        </dependency>

或

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