springboot 2.1.1 整合Activiti 以及 activiti-modeler 5.22（汉化）（一）
一 .整合Activiti
需要材料 Activiti-activiti-5.22.0 源码包 可以官方下载 点击下载
-
添加依赖（这面是把spring security 给去掉了）
org.activiti activiti-spring-boot-starter-basic 5.22.0 spring-boot-starter-security org.springframework.boot org.activiti activiti-modeler 5.22.0 spring-security-config org.springframework.security spring-security-crypto org.springframework.security spring-security-web org.springframework.security org.activiti activiti-diagram-rest 5.22.0 spring-security-config org.springframework.security spring-security-crypto org.springframework.security spring-security-web org.springframework.security
2.修改入口（如果项目没有整合spring security 请加入下面代码，不然项目会报错）
//排除spring Security 如果你项目使用的是这个就不用配置
@SpringBootApplication(exclude = SecurityAutoConfiguration.class)
@MapperScan("com.chenkang.decheng.mapper")
public class DechengApplication {
public static void main(String[] args) {
SpringApplication.run(DechengApplication.class, args);
}
}
3 下载源码包找到
Activiti-activiti-5.22.0\modules\activiti-modeler\src\main\java\org\activiti\rest\editor 把model 下的方法和main 下的方法放到自己的项目中
4。在找到 Activiti-activiti-5.22.0\modules\activiti-webapp-explorer2\src\main\webapp 复制内容到自己的static 目录下 让他作为静态资源访问
resorces 下添加
就是那个汉化文件
5 。配置
import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Data
@Component
public class ActivitiDataSourceProperties {
@Value("${spring.datasource.url}")
private String url;
@Value("${spring.datasource.username}")
private String username;
@Value("${spring.datasource.password}")
private String password;
@Value("${spring.datasource.driver-class-name}")

}

@Configuration
public class ActivitiDatadourceConfig extends AbstractProcessEngineAutoConfiguration {
@Resource

@Bean
@Primary
public DataSource activitiDataSource() {

DruiddataSource.setPassword(activitiDataSourceProperties.getPassword());
DruiddataSource.setUsername(activitiDataSourceProperties.getUsername());
return DruiddataSource;
}
@Bean

return new DataSourceTransactionManager(activitiDataSource());
}
@Bean

configuration.setDataSource(activitiDataSource());
configuration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
configuration.setJobExecutorActivate(true);
configuration.setTransactionManager(transactionManager());
return configuration;
}
}
6 创建 控制层

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@Controller
public class ActivitiModelController {
private static final Logger log = LogManager.getLogger(ActivitiModelController.class);
@Autowired
ProcessEngine processEngine;
@Autowired
ObjectMapper objectMapper;
/**
* 新建一个空模型
*/
@RequestMapping("/create")
public void newModel(HttpServletResponse response) throws IOException {
RepositoryService repositoryService = processEngine.getRepositoryService();
//初始化一个空模型
Model model = repositoryService.newModel();
//设置一些默认信息
String name = "new-process";
String description = "";
int revision = 1;
String key = "process";
ObjectNode modelNode = objectMapper.createObjectNode();
modelNode.put(ModelDataJsonConstants.MODEL_NAME, name);

model.setName(name);
model.setKey(key);
model.setMetaInfo(modelNode.toString());
repositoryService.saveModel(model);
String id = model.getId();
//完善ModelEditorSource
ObjectNode editorNode = objectMapper.createObjectNode();
editorNode.put("id", "canvas");
editorNode.put("resourceId", "canvas");
ObjectNode stencilSetNode = objectMapper.createObjectNode();
stencilSetNode.put("namespace",
"http://b3mn.org/stencilset/bpmn2.0#");
editorNode.put("stencilset", stencilSetNode);
repositoryService.addModelEditorSource(id,editorNode.toString().getBytes("utf-8"));
response.sendRedirect("/modeler.html?modelId="+id);
}
/**
* 获取所有模型
*/
@RequestMapping("/modelList")
@ResponseBody
public Object modelList(){
RepositoryService repositoryService = processEngine.getRepositoryService();
return repositoryService.createModelQuery().list();
}
/**
* 发布模型为流程定义
*/
@RequestMapping("/deploy")
@ResponseBody
public Object deploy(String modelId) throws Exception {
//获取模型
RepositoryService repositoryService = processEngine.getRepositoryService();
Model modelData = repositoryService.getModel(modelId);
byte[] bytes = repositoryService.getModelEditorSource(modelData.getId());
if (bytes == null) {
return "模型数据为空，请先设计流程并成功保存，再进行发布。";
}
JsonNode modelNode = new ObjectMapper().readTree(bytes);
BpmnModel model = new BpmnJsonConverter().convertToBpmnModel(modelNode);
if(model.getProcesses().size()==0){
return "数据模型不符要求，请至少设计一条主线流程。";
}
byte[] bpmnBytes = new BpmnXMLConverter().convertToXML(model);
//发布流程
String processName = modelData.getName() + ".bpmn20.xml";
Deployment deployment = repositoryService.createDeployment()
.name(modelData.getName())
.addString(processName, new String(bpmnBytes, "UTF-8"))
.deploy();
modelData.setDeploymentId(deployment.getId());
repositoryService.saveModel(modelData);
return "SUCCESS";
}
/**
* 启动流程
*/
@RequestMapping("/start")
@ResponseBody
public Object startProcess(String keyName) {
ProcessInstance process = processEngine.getRuntimeService().startProcessInstanceByKey(keyName);
return process.getId() + " : " + process.getProcessDefinitionId();
}
/**
* 提交任务
*/
@RequestMapping("/run")
@ResponseBody
public Object run(String processInstanceId) {
Task task = processEngine.getTaskService().createTaskQuery().processInstanceId(processInstanceId).singleResult();
log.info("task {} find ", task.getId());
processEngine.getTaskService().complete(task.getId());
return "SUCCESS";
}
}
7,修改前端的配置 editor-app/app-cfg.js

*/
'use strict';
var ACTIVITI = ACTIVITI || {};
ACTIVITI.CONFIG = {
'contextRoot' : '/service',
};
控制层修改 引入的三个类都要加上
@RequestMapping("service")启动项目访问页面 /create 效果如下(汉化文件已经放在下载包内，需要的可以下载 ）
最后说明下： 如果你的项目自己配置数据源不通过自动注入 可以吧自己定义的数据源 作为参数
@Bean
@ConfigurationProperties("spring.datasource.druid.master")
public DataSource masterDataSource(DruidProperties druidProperties)
{
DruidDataSource dataSource = DruidDataSourceBuilder.create().build();
return druidProperties.dataSource(dataSource);
}
@Bean
@ConfigurationProperties("spring.datasource.druid.slave")
@ConditionalOnProperty(prefix = "spring.datasource.druid.slave", name = "enabled", havingValue = "true")
public DataSource slaveDataSource(DruidProperties druidProperties)
{
DruidDataSource dataSource = DruidDataSourceBuilder.create().build();
return druidProperties.dataSource(dataSource);
}
@Bean(name = "dynamicDataSource")
@Primary
public DynamicDataSource dataSource(DataSource masterDataSource)
{
Map targetDataSources = new HashMap<>();
targetDataSources.put(DataSourceType.MASTER.name(), masterDataSource);
setDataSource(targetDataSources, DataSourceType.SLAVE.name(), "slaveDataSource");
return new DynamicDataSource(masterDataSource, targetDataSources);
}
@Bean
public PlatformTransactionManager transactionManager(DataSource dataSource) {
return new DataSourceTransactionManager(dataSource(dataSource));
}
@Bean
public SpringProcessEngineConfiguration springProcessEngineConfiguration(DataSource dataSource) {
SpringProcessEngineConfiguration configuration = new SpringProcessEngineConfiguration();
configuration.setDataSource(dataSource(dataSource));
configuration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
configuration.setJobExecutorActivate(true);
configuration.setTransactionManager(transactionManager(dataSource));
return configuration;
}
例如这样的多数据源配置
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class,SecurityAutoConfiguration.class })
注解也要修改
修改自定义表单和自定义人员选择在后面文章
