[](()1.2 添加整合的配置文件

添加一个Spring的配置文件,并在其中完成Activiti的整合操作

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:tx="http://www.springframework.org/schema/tx"

xmlns:aop="http://www.springframework.org/schema/aop"

xsi:schemaLocation="http://www.springframework.org/schema/beans

<!--

数据库策略

flase: 默认值。activiti在启动时,会对比数据库表中保存的版本,如果没有表或者版本不匹配,将抛出异常。(生产环境常用)

</beans>

databaseSchemaUpdate的取值注意:

flase: 默认值。activiti在启动时,会对比数据库表中保存的版本,如果没有表或者版本不匹配,将抛出异常。(生产环境常用)

true: activiti会对数据库中所有表进行更新操作。如果表不存在,则自动创建。(开发时常用)

create_drop: 在activiti启动时创建表,在关闭时删除表(必须手动关闭引擎,才能删除表)。(单元测试常用)

drop-create: 在activiti启动时删除原来的旧表,然后在创建新表(不需要手动关闭引擎)。

[](()1.3 创建测试类测试

package com.bobo.test;

import org.activiti.engine.RepositoryService;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = {"classpath:activiti-spring.xml"})

public class ActivitiTest {

@Autowired

private RepositoryService repositoryService;

@Test

public void test01(){

System.out.println(repositoryService);

}

}

通过方法的执行我们能够发现相关的表结构在数据库中完成了创建,说明Activiti和Spring的整合成功。

[](()2. 和SpringBoot的整合


Activiti7发布正式版本之后,它和SpringBoot2.x已经完全整合开发了

[](()2.1 添加相关的依赖

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-test</artifactId>

<scope>test</scope>

<exclusions>

<exclusion>

<groupId>org.junit.vintage</groupId>

<artifactId>junit-vintage-engine</artifactId>

</exclusion>

</exclusions>

</dependency>

<dependency>

<groupId>org.activiti</groupId>

<artifactId>activiti-spring-boot-starter</artifactId>

<version>7.0.0.Beta2</version>

</dependency>

<dependency>

<groupId>mysql</groupId>

<artifactId>mysql-connector-java</artifactId>

</dependency>

<dependency>

<groupId>org.projectlombok</groupId>

<artifactId>lombok</artifactId>

</dependency>

[](()2.2 修改配置文件

配置Spring的数据源

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

spring.datasource.url=jdbc:mysql:///activiti?characterEncoding=utf-8&nullCatalogMeansCurrent=true&serverTimezone=UTC

spring.datasource.name=root

spring.datasource.password=123456

activiti的配置

#1.flase:默认值。activiti在启动时,对比数据库表中保存的版本,如果没有表或者版本不匹配,将抛出异常

#2.true: activiti会对数据库中所有表进行更新操作。如果表不存在,则自动创建

#3.create_drop: 在activiti启动时创建表,在关闭时删除表(必须手动关闭引擎,才能删除表)

#4.drop-create: 在activiti启动时删除原来的旧表,然后在创建新表(不需要手动关闭引擎)

spring.activiti.database-schema-update=true

检测历史表是否存在, Activiti7中默认是没有开启数据库历史记录的,启动数据库历史记录

spring.activiti.db-history-used=true

#记录历史等级 可配置的历史级别有none, activity, audit, full

#none:不保存任何的历史数据,因此,在流程执行过程中,这是最高效的。

#activity:级别高于none,保存流程实例与流程行为,其他数据不保存。

#audit:除activity级别会保存的数据外,还会保存全部的流程任务及其属性。audit为history的默认值。

#full:保存历史数据的最高级别,除了会保存audit级别的数据外,还会保存其他全部流程相关的细节数据,包括一些流程参数等。

spring.activiti.history-level=full

校验流程文件,默认校验resouces下的 process 文件夹里的流程文件

spring.activiti.check-process-definitions=false

[](()2.3 整合SpringSecurity

因为Activiti7和SpringBoot整合后,默认情况下,集成了SpringSecurity安全框架,这样我们就要准备SpringSecurity的相关配置信息

添加一个SpringSecurity的工具类

package com.bobo.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.context.annotation.ComponentScan;

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;

@Component

public 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<? extends GrantedAuthority> getAuthorities() {

return user.getAuthorities();

}

@Override

public Object getCredentials() {

return user.getPassword();

}

@Override

public Object getDetails() {

return user;

}

@Override

public Object getPrincipal() {

return user;

}

@Override

public boolean isAuthenticated() {

return true;

}

@Override

public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {

}

@Override

public String getName() {

return user.getUsername();

}

}));

org.activiti.engine.impl.identity.Authentication.setAuthenticatedUserId(username);

}

}

这个类可以从Activiti7官方提供的Example中找到。

添加一个SpringSecurity的配置文件

package com.bobo.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;

@Configuration

public class SpringSecurityConfiguration {

private Logger logger = LoggerFactory.getLogger(SpringSecurityConfiguration.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<String> 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();

}

}

[](()2.4 创建bpmn文件

创建一个简单的bpmn文件,并设置任务的用户组,CandidateGroups,CandidateGroups中的内容要与在SpringSecurity的配置文件中配置的用户组的名称要保持一致,可以填写activitTeam或者otherTeam。这样填写的好处是,当不确定到底由谁来负责当前的任务的时候,只要是Groups内的用户都可以拾取这个任务

在这里插入图片描述

Activiti7中可以自动部署流程,前提是在resources目录下,创建一个新的目录processes,用来放置bpmn文件

在这里插入图片描述

[](()2.5 单元测试

package com.bobo;

import com.bobo.utils.SecurityUtil;

import org.activiti.api.process.model.ProcessDefinition;

import org.activiti.api.process.model.ProcessInstance;

import org.activiti.api.process.model.builders.ProcessPayloadBuilder;

import org.activiti.api.process.runtime.ProcessRuntime;

import org.activiti.api.runtime.shared.query.Page;

import org.activiti.api.runtime.shared.query.Pageable;

import org.activiti.api.task.model.Task;

import org.activiti.api.task.model.builders.ClaimTaskPayloadBuilder;

import org.activiti.api.task.model.builders.TaskPayloadBuilder;

import org.activiti.api.task.model.payloads.ClaimTaskPayload;

import org.activiti.api.task.runtime.TaskRuntime;

import org.activiti.engine.RepositoryService;

import org.junit.jupiter.api.Test;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest

class ActSpringbootApplicationTests {

@Autowired

private ProcessRuntime processRuntime;

@Autowired

private TaskRuntime taskRuntime;

@Autowired
