摘要
本篇随笔主要记录springBoot2集成activiti流程引擎，而且嵌入activiti的在线设计器，能够经过浏览器直接编辑出咱们须要的流程，不须要经过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。javascript

所需软件版本
springBoot 2.0.1.RELEASE
activiti 5.22.0 官网下载地址
activiti-webapp-explorer2 个人github上的explorer项目 -
集成方法
activiti支持多种数据库，自己还有个h2的内存数据库，我这里用的是Mysql
一、pom.xml引入依赖，这里主要是activiti的依赖包，${activiti.version}为5.22.0<!--spring activiti start--> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring-boot-starter-basic</artifactId> <version>${activiti.version}</version> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </exclusion> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </exclusion> <exclusion> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring-boot-starter-actuator</artifactId> <version>${activiti.version}</version> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-rest</artifactId> <version>${activiti.version}</version> <exclusions> <exclusion> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-explorer</artifactId> <version>${activiti.version}</version> <exclusions> <exclusion> <groupId>com.vaadin</groupId> <artifactId>vaadin</artifactId> </exclusion> <exclusion> <groupId>org.vaadin.addons</groupId> <artifactId>dcharts-widget</artifactId> </exclusion> <exclusion> <groupId>activiti-simple-workflow</groupId> <artifactId>org.activiti</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-diagram-rest</artifactId> <version>${activiti.version}</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-simple-workflow</artifactId> <version>${activiti.version}</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring</artifactId> <version>${activiti.version}</version> </dependency> <dependency> <groupId>org.apache.xmlgraphics</groupId> <artifactId>batik-codec</artifactId> <version>1.7</version> </dependency> <dependency> <groupId>org.apache.xmlgraphics</groupId> <artifactId>batik-css</artifactId> <version>1.7</version> </dependency> <dependency> <groupId>org.apache.xmlgraphics</groupId> <artifactId>batik-svg-dom</artifactId> <version>1.7</version> </dependency> <dependency> <groupId>org.apache.xmlgraphics</groupId> <artifactId>batik-svggen</artifactId> <version>1.7</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> <version>4.1.3.RELEASE</version> </dependency> <!--spring activiti end-->
二、拷贝项目资源
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到本身的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。
三、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后面改为 /service，和controller里面加的requestMapping要一致
css -
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，本身能够根据实现类本身添加接口方法，这个service实现了把流程和自定义表单结合的功能，completeTask方法经过java反射执行不一样任务节点执行不一样form

// List<HistoricDetail> datas = historyService.createHistoricDetailQuery() // .activityInstanceId(act.getId()).list(); // System.out.println("使用activityInstanceId方法查询：" + datas.size()); // datas = historyService.createHistoricDetailQuery().excludeTaskDetails().list(); // System.out.println("使用excludeTaskDetails方法查询：" + datas.size()); // datas = historyService.createHistoricDetailQuery().formProperties().list(); // System.out.println("使用formProperties方法查询：" + datas.size()); // datas = historyService.createHistoricDetailQuery().processInstanceId("processInstanceId").list(); // System.out.println("使用processInstanceId方法查询：" + datas.size()); // datas = historyService.createHistoricDetailQuery().taskId("taskId").list(); // System.out.println("使用taskId方法查询：" + datas.size()); // datas = historyService.createHistoricDetailQuery().variableUpdates().list(); // System.out.println("使用variableUpdates方法查询：" + datas.size()); // } }
启动流程、用户任务task查询、业务处理、流程进度查看等等，历史流程查看功能没有验证过，这部分代码是注释掉的
5、页面实现
在templates放置显示页面，可本身根据喜爱放置，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，改成上面的activitiForm里面的form页面，不一样的页面对应不一样流程节点
list.html模型列表页

运行界面以下
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，我本身定义了两个用户userzhou和usertest，form key填写处理当前节点所用的form表单，也就是以前的applyForm和approveForm -
须要注意的地方
一、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，但仍是存在校验，最后没办法在act_id_user里面加了一条数据，你们有解决的办法能够在下方给我评论，谢谢。springboot配置文件添加security.basic.enabled=false，未验证
二、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
View Codepackage 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/"); } }
三、关闭编辑器的时候能够自定义返回的页面
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，能够修改放回路径，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"; }); };
源码已经发到码云，各位能够去拉取
