解决Springboot集成ActivitiModel提示输入用户名密码的问题

activiti-modeler 依赖要排除掉spring-security 相关的依赖。
包括：
spring-security-config
spring-security-core
spring-security-web
spring-security-crypto

pom.xml 写法如下

<!-- Activiti 在线设计 -->
        <dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-modeler</artifactId>
