摘要
本篇随笔主要记录springBoot2集成activiti流程引擎，并且嵌入activiti的在线设计器，可以通过浏览器直接编辑出我们需要的流程，不需要通过eclipse或者IDEA的actiBpm插件设计流程再直接部署到项目下，页面保存流程后可直接发布、发起流程。
所需软件版本
springBoot 2.0.1.RELEASE
activiti 5.22.0 官网下载地址
activiti-webapp-explorer2 我的github上的explorer项目-
集成方法
activiti支持多种数据库，本身还有个h2的内存数据库，我这里用的是Mysql
1、pom.xml引入依赖，这里主要是activiti的依赖包，${activiti.version}为5.22.0<!--spring activiti start-->

解压activiti-webapp-explorer2，把webapp下面的diagram-viewer、editor-app、modeler.html复制到springboot项目下的static下，这是activiti的在线设计器，modeler.html就是设计的主界面，复制resources下stencilset.json到自己的resources下。
解压activiti-5.22.0的包，将libs下的activiti-modeler-5.22.0-sources.jar解压出来，把org\activiti\rest\editor路径下的main、model文件夹复制到springboot项目的源码路径下，里面有三个类，主要用于读取stencilset.json。
3、修改拷贝过来的资源文件
修改StencilsetRestResource.java、ModelEditorJsonRestResource.java、ModelSaveRestResource.java3个controller，加上@RequestMapping("/service")修改editor-app下的app-cfg.js，把contextRoot后面改成 /service，和controller里面加的requestMapping要一致
-
var ACTIVITI = ACTIVITI || {}; ACTIVITI.CONFIG = {
'contextRoot' : '/service',
};4、新增service、controller
service实现，这里只放实现类，接口就不放了，自己可以根据实现类自己添加接口方法，这个service实现了把流程和自定义表单结合的功能，completeTask方法通过java反射执行不同任务节点执行不同formpackage com.djkj.activiti.service.Impl; import com.djkj.activiti.bean.ActivitiVariable;

5、页面实现
在templates放置显示页面，可自己根据喜好放置，我这里主要是跟controller里返回的路径对应model文件夹下放的是模型列表页和用户任务列表页，form.html已经废弃，改为上面的activitiForm里面的form页面，不同的页面对应不同流程节点
list.html模型列表页 -

运行界面如下
list.html列表页新建页面
这里主要注意连个地方，assignments表示当前节点的处理人的id，我自己定义了两个用户userzhou和usertest，form key填写处理当前节点所用的form表单，也就是之前的applyForm和approveForm
-
需要注意的地方 1、去除activiti的security校验，修改application启动类
@SpringBootApplication(scanBasePackages = {"com.djkj","org.activiti"} , exclude = { org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class, org.activiti.spring.boot.SecurityAutoConfiguration.class,})
这是按照网上的写的，但还是存在校验，最后没办法在act_id_user里面加了一条数据，大家有解决的办法可以在下方给我评论，谢谢。springboot配置文件添加security.basic.enabled=false，未验证2、访问静态资源的时候，可能会被dispatcherservlet 给拦截掉，我是添加了个资源处理器，拦截static静态资源
package com.djkj.activiti.common; import groovy.util.logging.Slf4j;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; @Configuration
@Slf4j
@EnableWebMvc
public class StaticResourceConfig implements WebMvcConfigurer { @Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
} }3、关闭编辑器的时候可以自定义返回的页面
修改editor-app\configuration下的toolbar-default-actions.js，有俩个地方closeEditor方法和$scope.saveAndClose方法，一个是关闭一个是保存并关闭，可以修改放回路径，对应的是controller里的路径closeEditor: function(services) {
window.location.href = "/models/modelList";
}, $scope.saveAndClose = function () {
$scope.save(function() {
window.location.href = "/models/modelList";
});
};
