activiti自定義流程之Spring整合activiti-modeler5.16例項（一）：環境搭建
阿新 • • 發佈：2019-02-19
專案中需要整合activiti-modeler自定義流程，找了很多資料後，終於成功的跳轉到activiti-modeler流程設計介面，以下是記錄：
一、整合基礎：eclipse4.4.1、tomcat7、jdk1.7、mysql5.6.25、maven3.2.5、activiti5.16.3、spring4.0.9
二、步驟：
1、下載activiti-5.16.3.zip: http://www.activiti.org/download.html
2、解壓zip檔案，解壓後的目錄開啟如下：
3、開啟上圖中wars，可看到如下：
4、把上圖中的api、editor、explorer、libs複製到專案的webapp下，如圖：
5、進入第三步所示的WEB-INF的classes目錄，可看到如圖：
6、把上圖中的editor.html、stencilset.json、plugins.xml複製到專案的src/main/sources中，（spring.xml是自己建立的）如圖：
7、配置web.xml檔案，整個檔案內容如下：
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <filter> <description>字符集過濾器</description> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <description>字符集編碼</description> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>RestletServlet</servlet-name> <servlet-class>org.restlet.ext.servlet.ServerServlet</servlet-class> <init-param> <param-name>org.restlet.application</param-name> <param-value>org.activiti.rest.editor.application.ModelerRestApplication</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>RestletServlet</servlet-name> <url-pattern>/service/*</url-pattern> </servlet-mapping> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>activiti.html</welcome-file> <welcome-file>activiti.htm</welcome-file> <welcome-file>activiti.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app>
8、使用maven匯入需要的pring、activiti以及mysql的jar包。Pom.xml內容如下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>activitiTest1</groupId> <artifactId>activitiTest1</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>activitiTest1 Maven Webapp</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.0.9.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.0.9.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>4.0.9.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.0.9.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.0.9.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.0.9.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.0.9.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>4.0.9.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>4.0.9.RELEASE</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.2.3</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.2.3</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.2.3</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-modeler</artifactId> <version>5.16</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-engine</artifactId> <version>5.16</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-explorer</artifactId> <version>5.16</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-rest</artifactId> <version>5.16</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.0.9.RELEASE</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.34</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring</artifactId> <version>5.16</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.0.9.RELEASE</version> </dependency> </dependencies> <build> <finalName>activitiTest1</finalName> </build> </project>
9、建立spring的配置檔案spring.xml,如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<context:annotation-config />
<mvc:annotation-driven />
<context:component-scan base-package="controllers" />
<bean id="dataSource" class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
<property name="url" value="jdbc:mysql://192.168.0.201:3306/testtu?useUnicode=true&characterEncoding=utf8" ></property>
<property name="username" value="root" ></property>
<property name="password" value="123456" ></property>
</bean>
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<property name="dataSource" ref="dataSource" />
<property name="databaseSchemaUpdate" value="true" />
<property name="jobExecutorActivate" value="false"/>
<property name="history" value="full"/>
<property name="transactionManager" ref="transactionManager" />
<!-- 配置事務管理器，統一事務 -->
<!-- 設定建表策略，如果沒有表，自動建立表 -->
</bean>
<!-- 建立流程引擎物件 -->
<bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
<property name="processEngineConfiguration" ref="processEngineConfiguration" />
</bean>
<!-- 由流程引擎物件，提供的方法，建立專案中使用的Activiti工作流的Service -->
<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
<bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" />
<bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" />
<bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" />
<bean id="formService" factory-bean="processEngine" factory-method="getFormService" />
<!-- 避免IE執行AJAX時,返回JSON出現下載檔案 -->
<bean id="mappingJacksonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- 啟動Spring MVC的註解功能，完成請求和註解POJO的對映 -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="mappingJacksonHttpMessageConverter" /><!-- json轉換器 -->
</list>
</property>
</bean>
</beans> 10、建立controller類，用來控制頁面跳轉到activiti-modeler流程設計頁面：
package controllers;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.activiti.editor.constants.ModelDataJsonConstants;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.repository.Model;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
@Controller
public class ActivitiController {
@Autowired
private RepositoryService repositoryService;
/**
* 查詢生日列表
*
* @param req
* @return
*/
@RequestMapping(value = "/activiti.do", method = RequestMethod.GET, produces = "application/json;charset=utf-8")
@ResponseBody
public Object brithdayList(HttpServletRequest req) {
Map<String, Object> map = new HashMap<String, Object>();
map.put("name", "activiti");
return map;
}
@RequestMapping(value = "/create.do", method = RequestMethod.GET, produces = "application/json;charset=utf-8")
public void create(
@RequestParam("name") String name,
@RequestParam("key") String key,
@RequestParam(value = "description", required = false) String description,
HttpServletRequest request, HttpServletResponse response) {
try {
ObjectMapper objectMapper = new ObjectMapper();
ObjectNode modelObjectNode = objectMapper.createObjectNode();
modelObjectNode.put(ModelDataJsonConstants.MODEL_NAME, name);
modelObjectNode.put(ModelDataJsonConstants.MODEL_REVISION, 1);
modelObjectNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION,
org.apache.commons.lang3.StringUtils
.defaultString(description));
Model newModel = repositoryService.newModel();
newModel.setMetaInfo(modelObjectNode.toString());
newModel.setName(name);
newModel.setKey(key);
repositoryService.saveModel(newModel);
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(newModel.getId(), editorNode
.toString().getBytes("utf-8"));
response.sendRedirect(request.getContextPath()
+ "/service/editor?id=" + newModel.getId());
} catch (Exception e) {
e.getStackTrace();
}
}
}11、修改index.jsp為activiti.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<h2>Hello World!</h2>
<a href="./activiti.do">activiti</a>
<form action="./create.do" method="get">
<input type="text" id="name" name="name"></input>
<input type="text" id="key" name="key"></input>
<input type="text" id="description" name="description"></input>
<input type="submit" value="提交">
</form>
</body>
</html>12、啟動專案，使用http://localhost:8080/activitiTest1訪問專案，看到如下頁面：
13、點選提交後，跳轉到流程圖設計介面：
