1：在pom添加依赖

<!-- activiti流程引擎 -->
		<dependency>
			<groupId>org.activiti</groupId>
			<artifactId>activiti-spring-boot-starter</artifactId>
			<version>7.1.0.M6</version>
			<exclusions>
				<exclusion><!-- 排除activiti的mybatis，避免和外面的mybatis-plus冲突 -->
					<artifactId>mybatis</artifactId>
					<groupId>org.mybatis</groupId>
				</exclusion>
<!--				<exclusion>
					<groupId>org.springframework.security</groupId>
					<artifactId>spring-security-config</artifactId>
				</exclusion>
				<exclusion>
					<groupId>org.springframework.security</groupId>
					<artifactId>spring-security-crypto</artifactId>
				</exclusion>
				<exclusion>
					<groupId>org.springframework.security</groupId>
					<artifactId>spring-security-web</artifactId>
				</exclusion>-->
			</exclusions>
		</dependency>
		<dependency>
			<groupId>org.activiti.dependencies</groupId>
			<artifactId>activiti-dependencies</artifactId>
			<version>7.1.0.M6</version>
			<type>pom</type>
		</dependency>

2：在yml下添加

spring:
 activiti:
    async-executor-activate: false
    check-process-definitions: false
    database-schema-update: true
    history-level: full
    db-history-used: true
    deployment-mode: never-fail
    datasource:
      jdbc-url: jdbc:mysql://192.168.18.188:3306/activiti?characterEncoding=UTF-8&useUnicode=true&useSSL=false&tinyInt1isBit=false&allowPublicKeyRetrieval=true&serverTimezone=Asia/Shanghai&nullCatalogMeansCurrent=true
      username: root
      password: 123456
      driver-class-name: com.mysql.jdbc.Driver

3：在SpringBootApplication启动类添加如下注解

@SpringBootApplication(exclude = {ActivitiSpringIdentityAutoConfiguration.class})

4：在shiro框架的ShiroConfig配置类验证添加如果规则放行

		//activiti
        filterChainDefinitionMap.put("/activiti/**", "anon");
        filterChainDefinitionMap.put("/diagram-viewer/**", "anon");
        filterChainDefinitionMap.put("/editor-app/**", "anon");

5： 添加一个Activiti的验证自动配置类

package org.jeecg.config.activiti;

import org.activiti.api.runtime.shared.identity.UserGroupManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.ArrayList;
import java.util.List;

@Configuration
public class ActivitiSpringIdentityAutoConfiguration {

   @Bean
   public UserGroupManager userGroupManager() {
       return new UserGroupManager() {
           @Override
           public List<String> getUserGroups(String s) {
               return new ArrayList<>();
          }
           @Override
           public List<String> getUserRoles(String s) {
               return null;
          }
           @Override
           public List<String> getGroups() {
               return null;
          }
           @Override
           public List<String> getUsers() {
               return null;
          }
      };
  }

}
