activiti自定义流程之Spring整合activiti-modeler5.16实例（一）：环境搭建
项目中需要整合activiti-modeler自定义流程，找了很多资料后，终于成功的跳转到activiti-modeler流程设计界面，以下是记录：
一、整合基础：eclipse4.4.1、tomcat7、jdk1.7、mysql5.6.25、maven3.2.5、activiti5.16.3、spring4.0.9
二、步骤：
1、下载activiti-5.16.3.zip: http://www.activiti.org/download.html
2、解压zip文件，解压后的目录打开如下：
3、打开上图中wars，可看到如下：
4、把上图中的api、editor、explorer、libs复制到项目的webapp下，如图：
5、进入第三步所示的WEB-INF的classes目录，可看到如图：
6、把上图中的editor.html、stencilset.json、plugins.xml复制到项目的src/main/sources中，（spring.xml是自己建立的）如图：
7、配置web.xml文件，整个文件内容如下：
<?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"

8、使用maven导入需要的pring、activiti以及mysql的jar包。Pom.xml内容如下：
<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">

</build>
</project>
9、建立spring的配置文件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" />
<!-- 配置事务管理器，统一事务 -->
<!-- 设置建表策略，如果没有表，自动创建表 -->
</bean>
<!-- 创建流程引擎对象 -->
<bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
<property name="processEngineConfiguration" ref="processEngineConfiguration" />
</bean>
<!-- 由流程引擎对象，提供的方法，创建项目中使用的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执行AJAX时,返回JSON出现下载文件 -->
<bean id="mappingJacksonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->
</list>
</property>
</bean>
</beans>
10、建立controller类，用来控制页面跳转到activiti-modeler流程设计页面：
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;
/**
* 查询生日列表
*
* @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为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、启动项目，使用http://localhost:8080/activitiTest1访问项目，看到如下页面：
13、点击提交后，跳转到流程图设计界面：
