1 SpringBoot整合 Activiti7 的配置

为了能够实现 SpringBoot Activiti7 整合开发,首先我们要引入相关的依赖支持。
所以,我们在工程的 pom.xml 文件中引入相关的依赖,具体依赖如下所示:

<properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

<java.version>1.8</java.version>

</properties>

<dependencies>

<dependency>

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

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

</dependency>

<dependency>

<groupId>mysql</groupId>

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

</dependency>

<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>

</dependency>

<!-- https://mvnrepository.com/artifact/org.activiti/activiti-spring-boot-starter -->

<dependency>

<groupId>org.activiti</groupId>

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

<version>7.0.0.Beta2</version>

</dependency>

<dependency>

<groupId>org.mybatis</groupId>

<artifactId>mybatis</artifactId>

<version>3.4.5</version>

</dependency>

<dependency>

<groupId>mysql</groupId>

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

<version>8.0.15</version>

</dependency>

</dependencies>

<build>

<plugins>

<plugin>

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

<artifactId>spring-boot-maven-plugin</artifactId>

</plugin>

</plugins>

</build>

通过该 pom.xml 文件所导入的坐标,我们就可以实现 activiti7 Springboot 整合。

2 SpringBoot application.yml 文件配置

为了能够实现 Activiti7 生成的表放到 Mysql 数据库中,需要在 springboot 的配置文件 application.yml
中添加相关的配置

spring:

datasource:

url: jdbc:mysql://localhost:3306/activiti?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT

username : root

password : 123456

driver-class-name: com.mysql.jdbc.Driver

3添加 SpringSecurity 安全框架整合配置

因为 Activiti7 SpringBoot 整合后,默认情况下,集成了 SpringSecurity 安全框架,这样我们就要去
准备 SpringSecurity 整合进来的相关用户权限配置信息。
可以查看一下整合 SpringBoot 的依赖包,发现同时也将 SpringSecurity 的依赖包也添加进项目中了,
如下:

 3.1 添加 SecurityUtil

添加 SecurityUtil
为了能够快速实现 SpringSecurity 安全框架的配置,所添加的一个组件。

package com.topcheer.activiti;

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

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

publicclass SecurityUtil {

@Autowired

private UserDetailsService userDetailsService;

publicvoid logInAs(String username) {

UserDetails user = userDetailsService.loadUserByUsername(username);

if (user == null) {

thrownew IllegalStateException("User " + username + " doesn't exist, please provide a valid user");

}

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

publicboolean isAuthenticated() {

returntrue;

}

@Override

publicvoid setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {

}

@Override

public String getName() {

return user.getUsername();

}

}));

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

}

}

这个类可以从我们下载的 Activiti7 官方提供的 Example 中找到。

3.2 添加 DemoApplicationConfig

Activiti7 官方下载的 Example 中找到 DemoApplicationConfig 类,它的作用是为了实现
SpringSecurity 框架的用户权限的配置,这样我们就可以在系统中使用用户权限信息。本次项目中基
本是在文件中定义出来的用户信息,当然也可以是数据库中查询的用户权限信息。

4 使用 SpringBoot 整合 Junit 方式测试新特性

@RunWith(SpringRunner.class)

@SpringBootTest

publicclass ActivitiApplicationTests {

@Autowired

private ProcessRuntime processRuntime;

@Autowired

private TaskRuntime taskRuntime;

@Autowired

private SecurityUtil securityUtil;

//

// /**

// * 查看流程定义

// */

@Test

publicvoid contextLoads() {

securityUtil.logInAs("salaboy");

Page<ProcessDefinition> processDefinitionPage = processRuntime.processDefinitions(Pageable.of(0, 10));

System.out.println("可用的流程定义数量:" + processDefinitionPage.getTotalItems());

for (ProcessDefinition pd : processDefinitionPage.getContent()) {

System.out.println("流程定义:" + pd);

}

}

//

// /**

// * 启动流程实例

// */

@Test

publicvoid testStartProcess() {

securityUtil.logInAs("salaboy");

ProcessInstance pi = processRuntime.start(ProcessPayloadBuilder.start().withProcessDefinitionKey("myProcess_1")

.build());

System.out.println("流程实例ID:" + pi.getId());

//流程实例ID:6d2a9bc1-0cee-11ea-acf5-f894c25ebadd

}

//

/**

* 查询任务,并完成自己的任务

*/

@Test

publicvoid testTask() {

securityUtil.logInAs("ryandawsonuk"); //指定用户认证信息

Page<Task> taskPage=taskRuntime.tasks(Pageable.of(0,10)); //分页查询列表

if (taskPage.getTotalItems()>0){

//说明有任务,进行遍历

for (Task task:taskPage.getContent()){

//拾取任务

taskRuntime.claim(TaskPayloadBuilder.claim().withTaskId(task.getId()).build());

System.out.println("任务:"+task);

//完成任务

taskRuntime.complete(TaskPayloadBuilder.complete().withTaskId(task.getId()).build());

}

}

Page<Task> taskPage2=taskRuntime.tasks(Pageable.of(0,10));

if (taskPage2.getTotalItems()>0){

System.out.println("任务:"+taskPage2.getContent());

}

//任务:TaskImpl{id='6d310464-0cee-11ea-acf5-f894c25ebadd', owner='null', assignee='null', name='first', description='null', createdDate=Fri Nov 22 14:07:56 CST 2019, claimedDate=null, dueDate=null, priority=50, processDefinitionId='myProcess_1:1:7f72b399-0cec-11ea-8c61-f894c25ebadd', processInstanceId='6d2a9bc1-0cee-11ea-acf5-f894c25ebadd', parentTaskId='null', status=CREATED}

}

}
