一.pom依赖引入
通过该 pom.xml 文件所导入的坐标，我们就可以实现 activiti7 与 Springboot 整合
二.配置文件编写
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 : root
driver-class-name: com.mysql.jdbc.Driver
activiti:
db-history-used: true #进行相关activiti操作时，要生成history相关的表
history-level: full #history相关表中的历史记录都要被记录
说明：正常如果在配置文件中不加入activiti的配置，是不会生成相关历史记录表的，所以必须加上上面的activiti配置才能在数据库中生成对应的历史记录表
三.添加 SpringSecurity 安全框 架整合配置
因为 Activiti7 与 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。
1.添加 SecurityUtil工具类
package com.itheima.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
public class SecurityUtil {
@Autowired
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");
}
SecurityContextHolder.setContext(new SecurityContextImpl(new Authentication() {
@Override
public Collection 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);
}
}
2.添加 DemoApplicationConfig 类
在 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。

InMemoryUserDetailsManager inMemoryUserDetailsManager = new InMemoryUserDetailsManager();
String[][] usersGroupsAndRoles = {

for (String[] user : usersGroupsAndRoles) {
List
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;
}
@Override

http
.csrf().disable()

四.设置流程（构建bpmn文件）

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.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.TaskPayloadBuilder;
import org.activiti.api.task.runtime.TaskRuntime;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
/**

*/
@RunWith(SpringRunner.class)
@SpringBootTest
public class ActivitiTest {
@Autowired
private ProcessRuntime processRuntime; //流程定义相关
@Autowired
private TaskRuntime taskRuntime; //任务操作相关
@Autowired
private SecurityUtil securityUtil; //springsecurity相关的工具类
//流程定义信息查看
@Test
public void testDefinition(){
securityUtil.logInAs("salaboy"); //需要先认证
Page
System.out.println(page.getTotalItems());// 查看已部署的流程
//page.getContent()查看当前每一个部署的信息
for (ProcessDefinition processDefinition : page.getContent()) {
System.out.println(processDefinition);
}
}
//启动流程实例
@Test
public void testStartInstance(){
securityUtil.logInAs("salaboy");
ProcessInstance processInstance = processRuntime.start(ProcessPayloadBuilder
.start()
.withProcessDefinitionKey("myProcess_1")
.build());
System.out.println("流程实例id：" + processInstance.getId()); //流程实例id
}
//查询任务，并完成任务
@Test
public void testTask(){
securityUtil.logInAs("ryandawsonuk");
Page
if (tasks.getTotalItems() > 0) {
for (Task task : tasks.getContent()) {
System.out.println("任务1：" + task);
//拾取任务
taskRuntime.claim(TaskPayloadBuilder.claim().withTaskId(task.getId()).build());
//执行任务
taskRuntime.complete(TaskPayloadBuilder.complete().withTaskId(task.getId()).build());
}
}
//再次查看任务
tasks = taskRuntime.tasks(Pageable.of(0, 10));
if (tasks.getTotalItems() > 0) {
for (Task task : tasks.getContent()) {
System.out.println("任务2：" + task);
}
}
}
//查询任务，并完成任务
@Test
public void testTaskAll(){
securityUtil.logInAs("erdemedeiros");
Page
if (tasks.getTotalItems() > 0) {
for (Task task : tasks.getContent()) {
System.out.println("任务1：" + task);
//拾取任务
taskRuntime.claim(TaskPayloadBuilder.claim().withTaskId(task.getId()).build());
//执行任务
taskRuntime.complete(TaskPayloadBuilder.complete().withTaskId(task.getId()).build());
}
}
//再次查看任务
tasks = taskRuntime.tasks(Pageable.of(0, 10));
if (tasks.getTotalItems() > 0) {
for (Task task : tasks.getContent()) {
System.out.println("任务2：" + task);
}
}
}
}
六.整合SpringMVC
代码与测试类中相似
