在使用 SpringBoot 整合 Activiti 时，启动服务器，访问模块时，浏览器弹出一个登录界面，如下图所示，只有登录成功后才能访问。
环境
SpringBoot：2.2.1.RELEASE
Activiti：7.1.0.M2
Maven 依赖如下
<dependencies><dependency><groupId>org.mybatis.spring.bootgroupId><artifactId>mybatis-spring-boot-starterartifactId><version>2.1.1version>dependency><dependency><groupId>mysqlgroupId><artifactId>mysql-connector-javaartifactId><scope>runtimescope>dependency><dependency><groupId>com.alibabagroupId><artifactId>druid-spring-boot-starterartifactId><version>1.1.10version>dependency><dependency><groupId>org.activitigroupId><artifactId>activiti-spring-boot-starterartifactId><version>7.1.0.M2version>dependency><dependency><groupId>com.atguigugroupId><artifactId>atcrowdfunding_commonartifactId><version>0.0.1-SNAPSHOTversion><exclusions><exclusion><groupId>org.springframework.bootgroupId><artifactId>spring-boot-starterartifactId>exclusion>exclusions>dependency><dependency><groupId>org.springframework.bootgroupId><artifactId>spring-boot-starter-webartifactId>dependency><dependency><groupId>org.springframework.cloudgroupId><artifactId>spring-cloud-starter-netflix-eureka-clientartifactId>dependency><dependency><groupId>org.springframework.bootgroupId><artifactId>spring-boot-devtoolsartifactId><scope>runtimescope><optional>trueoptional>dependency><dependency><groupId>org.springframework.bootgroupId><artifactId>spring-boot-starter-testartifactId><scope>testscope><exclusions><exclusion><groupId>org.junit.vintagegroupId><artifactId>junit-vintage-engineartifactId>exclusion>exclusions>dependency>
dependencies>
产生的原因
出现该登录界面是因为 Activiti 框架整合了：security（权限的框架）
解决方法
在启动类上的 @SpringBootApplication 添加如下参数：
@SpringBootApplication(exclude = {org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class,org.springframework.boot.actuate.autoconfigure.security.servlet.ManagementWebSecurityAutoConfiguration.class})
public class AtcrowdfundingActivitiServiceApplication {public static void main(String[] args) {SpringApplication.run(AtcrowdfundingActivitiServiceApplication.class, args);}}
