pom.xml文件如下：

3 添加配置类（因为activiti内置了springboot的安全框架，所以需要配置）

项目目录如下：

该类是config下的DemoApplicationConfiguration类

package com.example.activiti8test.config;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.security.core.authority.SimpleGrantedAuthority;import org.springframework.security.core.userdetails.User;import org.springframework.security.core.userdetails.UserDetailsService;import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;import org.springframework.security.crypto.password.PasswordEncoder;import org.springframework.security.provisioning.InMemoryUserDetailsManager;import java.util.Arrays;import java.util.List;import java.util.stream.Collectors;@Configurationpublic class DemoApplicationConfiguration {    private Logger logger = LoggerFactory.getLogger(DemoApplicationConfiguration.class);    @Bean    public UserDetailsService myUserDetailsService() {        InMemoryUserDetailsManager inMemoryUserDetailsManager = new InMemoryUserDetailsManager();        //这里添加用户，后面处理流程时用到的任务负责人，需要添加在这里        String[][] usersGroupsAndRoles = {                {"jack", "password", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},                {"rose", "password", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},                {"tom", "password", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},                {"other", "password", "ROLE_ACTIVITI_USER", "GROUP_otherTeam"},                {"system", "password", "ROLE_ACTIVITI_USER"},                {"admin", "password", "ROLE_ACTIVITI_ADMIN"},        };        for (String[] user : usersGroupsAndRoles) {            List authoritiesStrings = Arrays.asList(Arrays.copyOfRange(user, 2, user.length));            logger.info("> Registering new user: " + user[0] + " with the following Authorities[" + authoritiesStrings + "]");            inMemoryUserDetailsManager.createUser(new User(user[0], passwordEncoder().encode(user[1]),                    authoritiesStrings.stream().map(s -> new SimpleGrantedAuthority(s)).collect(Collectors.toList())));        }        return inMemoryUserDetailsManager;    }    @Bean    public PasswordEncoder passwordEncoder() {        return new BCryptPasswordEncoder();    }}

4 添加安全工具类（也是因为安全框架）

该类是utils下的SecurityUtil

package com.example.activiti8test.utils;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.security.core.Authentication;import org.springframework.security.core.GrantedAuthority;import org.springframework.security.core.context.SecurityContextHolder;import org.springframework.security.core.context.SecurityContextImpl;import org.springframework.security.core.userdetails.UserDetails;import org.springframework.security.core.userdetails.UserDetailsService;import org.springframework.stereotype.Component;import java.util.Collection;@Componentpublic class SecurityUtil {    private Logger logger = LoggerFactory.getLogger(SecurityUtil.class);    @Autowired    @Qualifier("myUserDetailsService")    private UserDetailsService userDetailsService;    public void logInAs(String username) {        UserDetails user = userDetailsService.loadUserByUsername(username);        if (user == null) {            throw new IllegalStateException("User " + username + " doesn't exist, please provide a valid user");        }        logger.info("> Logged in as: " + username);        SecurityContextHolder.setContext(                new SecurityContextImpl(                        new Authentication() {                            @Override                            public Collection
