未能自省类 [org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration]

我用 spring boot 2.1.1 创建了一个项目，当我尝试解除它时，出现以下错误：

Answer 1

如果您的 POM 中有 spring-boot-starter-tomcat 的以下依赖项，请删除它的范围部分。

现存的：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

新的：

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

Answer 2

该错误很有帮助，因为它找不到所需的类javax.servlet.Filter，而获得此类的常见方法是通过此依赖项：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>

最终拉进来org.apache.tomcat.embed:tomcat-embed-core

我们在本地看到了这一点，因为当从 Intellij 运行 Spring Boot 应用程序时，我们没有在运行/调试配置中勾选“包含具有“提供”范围的依赖项”选项。

Answer 3

我认为这种依赖性：

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

与此发生冲突：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <type>jar</type>
</dependency>

为什么需要最后一项？我认为你不需要它，因为为了安全起见你已经有了启动器，所以删除它。
