1、缺少类

将activiti的依赖引入项目后，启动项目出现报错，具体报错信息如下：

Caused by: java.io.FileNotFoundException: class path resource [org/springframework/security/config/annotation/authentication/configurers/GlobalAuthenticationConfigurerAdapter.class]

1. ​具体原因​

​在启动项目时，ruoyi在扫描配置类时出现了问题。报错信息中提到了缺少 GlobalAuthenticationConfigurerAdapter.class类，这个类在 Spring Security 5.x 中已经被移除了，所以可能是由于版本兼容性问题导致的。

2. 解决方法

在启动器中剔除SecurityAutoConfiguration

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, org.activiti.spring.boot.SecurityAutoConfiguration.class, org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class})

2、无法找到bean的错误

在剔除SecurityAutoConfiguration之后，开始报一些无法找到bean的错误。

1. 具体原因：

猜测是activiti需要剔除Security的自动装配，但是其他类需要Security。

2. 解决办法：

在pom.xml中引入activiti的地方剔除Security包

<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-spring-boot-starter-basic</artifactId>
    <version>${activiti.version}</version>
    <exclusions>
        <exclusion>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </exclusion>
    </exclusions>
</dependency>

最后成功启动，解决问题。
