SpringMVC與Activiti網頁流程設計器整合

1.官方例子研究

Activiti給出的官方例子activiti-explorer中有一個網頁版的流程設計器,看起來很不錯的樣子。考慮到之後的工做中,可能會涉及到用戶本身設計流程,這樣的話,會要用到網頁版的流程設計器,所以,想辦法吧這個官網的網頁設計器從activiti-explorer工程中分離出來,與SpringMvc集成在一塊兒,這樣之後就能夠在本身的項目中直接設計流程,而後發佈運行了,不須要在Eclipse的Activiti插件中先將流程設計好,再導入項目中這麼麻煩了,並且後期的修改和維護更加的方便。咱們先能夠看一下activiti-explorer的例子中流程設計器的樣子。css

 

從官網上下載Activiti 5.18.0的壓縮包,下載地址: http://www.activiti.org/download.html 。html

將壓縮包解壓到任一目錄下。咱們能夠看到Activiti的目錄結構java

 

Database是存放Activiti須要用到的數據庫的各個版本的數據庫腳本。打開到具體的目錄咱們能夠看到,Activiti支持的數據庫包括h2,MySQLOracle,Postgre,db2,SQL Server。node

Docs中存放的是Activiti的參考文檔,都是網頁版的形式,裏面有一些使用API的文檔能夠參考使用。mysql

Libs中存放的是Activiti須要用到的各類jar包,之後若差什麼jar包找不到,能夠在這裏面查找添加到工程中。web

Wars裏面放的是Activiti的兩個例子工程,將這兩個工程放到一個tomcat的webapp目錄下,運行tomcat就能夠看到Activiti運行的整個過程。spring

 

將wars中的activiti-explorer.war 複製到一個tomcat的webapp目錄下,啓動tomcat。在瀏覽器中輸入 http://localhost:8080/activiti-explorer/,咱們能夠看到Activiti的登陸界面sql

 

使用帳戶 kermit/kermit 登陸系統,切換到流程便籤,咱們能夠看到系統中已經有的幾個流程的例子。數據庫

 

 

點擊此頁面上的「流程設計工做區」,點擊「新建模型」,填寫名稱,描述後點擊建立。express

 

以後,系統會跳轉到流程設計的界面上。

 

 

在左側工具欄中拖動控件到右邊的工做區,給各個模塊去一個名字以後,將流程用箭頭有機鏈接在一塊兒,就行成了一個完整的工做流,如下是一個簡單的財務報銷的流程。流程開始後,先要流程申請人提交財務報銷申請,提交完成以後,靖經理審批,財務審批,審批完成以後進入財務報銷環節,財務報銷以後,整個流程結束。十分的簡單明瞭。

 

 

 

 

 

2. 搭建SpringMVC框架。

2.1. 添加依賴文件

新建Maven工程,取名爲demo。在demo的pom文件中加入springMvc的依賴包,maven依賴以下。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2.2 配置spring-mvc.xml文件

在demo工程的src/main/resources下新建spring-mvc.xml文件,在文件中加入如下內容。

 

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://www.springframework.org/schema/context 

http://www.springframework.org/schema/context/spring-context-4.1.xsd 

http://www.springframework.org/schema/mvc 

http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

 

<!-- 自動掃描@Controller注入爲bean -->

<context:component-scan base-package="com.fh.server.controller" />

<property name="prefix" value="/" />

<property name="suffix" value=".jsp" />

</bean>

 

</beans>

 

2.3 Spring與Hibernate集成

在demo工程的src/main/resources目錄下新建spring-hibernate.xml文件,向文件中添加如下內容。

 

<?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:tx="http://www.springframework.org/schema/tx"

<!-- 鏈接池初始化鏈接數 -->

<property name="initialPoolSize" value="5" />

<property name="minPoolSize" value="5" />

<property name="maxPoolSize" value="20" />

<!--當鏈接池中的鏈接耗盡的時候c3p0一次同時獲取的鏈接數。默認值: 3 -->

<property name="acquireIncrement" value="5" />

</bean>

 

<!-- 配置hibernate的SessionFactory -->

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

<!-- 注入數據源 相關信息看源碼 -->

<property name="packagesToScan" value="com.fh.server.api.entity" />

</bean>

 

<!-- 配置事務管理器 -->

<bean id="transactionManager"

<!-- 指定在txAdvice切入點應用txAdvice事務加強處理 -->

<aop:advisor pointcut-ref="transactionPointcut"

advice-ref="transactionAdvice" />

</aop:config>

</beans>

 

 

配置完這些以後,還要在src/main/resources目錄下新建ehcache.xml文件,來配置hibernate的二級緩存。向ehcache.xml中加入如下內容

 

<?xml version="1.0" encoding="UTF-8"?>

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd">

<diskStore path="c:/ehcache" />

<!-- DefaultCache setting. -->

     <defaultCache

            maxElementsInMemory="1000"

            eternal="false"

            timeToIdleSeconds="120"

            timeToLiveSeconds="120"

            maxElementsOnDisk="1000000"

            overflowToDisk="true" 

            memoryStoreEvictionPolicy="LRU">

            

    </defaultCache>

 

<!-- Special objects setting. -->

<cache 

     name="org.andy.work.entity.AcctUser"

 maxElementsInMemory="2"

 memoryStoreEvictionPolicy="LRU" 

 eternal="true" 

 diskPersistent="false"

 overflowToDisk="false" 

 maxElementsOnDisk="1000000" /> 

</ehcache>

 

2.4配置spring.xml文件

在demo的src/main/resources目錄下新建spring.xml文件,向其中加入如下內容。

 

<?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:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.1.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.1.xsd">

<!-- 加載配置文件 -->

<context:property-placeholder location="classpath:config.properties"/>

<!-- 掃描service自動注入爲bean -->

<context:component-scan base-package="com.fh.server.service.impl,com.fh.server.dao.impl" />

</beans>

 

2.5 配置demo工程的web.xml文件

在demo工程的src/main/webapp目錄下新建WEB-INF文件夾,在WEB-INF文件夾中新增web.xml文件,向web.xml文件中加入如下內容。

 

<?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"

</session-config>

 

<welcome-file-list>

</welcome-file-list>

</web-app>

 

至此,咱們已經搭建好了SpringMVC+Spring+Hibernate的框架。能夠將項目部署到tomcat下,啓動tomcat在瀏覽器中輸入http://localhost:8080/demo, 就能夠看到咱們index.jsp中的內容,表示項目已經能夠運行。

3.2 配置spring-activiti.xml文件

在demo的src/main/resources目錄下新建spring-activiti.xml文件,向其中加入如下內容。

 

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans.xsd">

<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">

<property name="dataSource" ref="dataSource" />

<property name="transactionManager" ref="transactionManager" />

<property name="databaseSchemaUpdate" value="true" />

<property name="jobExecutorActivate" value="false" />

</bean>

 

<bean id="objectMapper" class="com.fasterxml.jackson.databind.ObjectMapper"/>

 

<bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">

<property name="processEngineConfiguration" ref="processEngineConfiguration" />

</bean>

 

<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="managementService" factory-bean="processEngine"

factory-method="getManagementService" />

<bean id="identityService" factory-bean="processEngine"

factory-method="getIdentityService" />

 

<bean id="transactionManager"

class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<property name="dataSource" ref="dataSource" />

</bean>

</beans>

 

3.3 修改web.xml文件

打開demo的web.xml文件,修改context-param爲如下內容,對比上面的web.xml文件可知,此處只是添加了classpath:spring-activiti.xml這一項。

 

<context-param>

<param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml,classpath:spring-hibernate.xml,classpath:spring-activiti.xml</param-value>

</context-param>

 

 

此時activiti已經與springMVC+Spring+Hibernate集成在一塊兒了,咱們可使用activiti提供的各類服務如repositoryService,runtimeService等。此處就不貼Junit的單元測試代碼了,這裏要寫的話,又能夠寫成一個文檔。

4.集成Activiti的在線流程設計器

4.1 複製文件。

下載activiti-webapp-explorer2的源代碼,將activiti-explorer工程中的diagram-viewer,editor-app和modeler.html文件複製到demo工程的src/main/webapp目錄下,將activiti-explorer工程中WEB-INF/classes文件加下的stencilset.json,ui.properties,ui.properties.alfresco複製到demo工程的src/main/resources目錄下。

 

 

 

複製完成以後的demo工程目錄以下。

 

 

4.2 複製Controller文件。

打開activiti5.18.0的源碼,將modules/目錄中找到org\activiti\rest\diagram和org\activiti\rest\editor這兩個包,將他們整個複製到demo工程的src/main/java目錄下。複製完成後目錄結構如圖。

 

4.3修改spring-mvc.xml文件

修改spring-mvc.xml文件,在其中加入如下內容,使spring在掃描controller類的時候,也掃描這些包裏面的類。

 

<!--加入Spring Activiti-Modeler的運行配置 -->

<context:component-scan base-package="org.activiti.rest.editor" />

<context:component-scan base-package="org.activiti.rest.diagram" />

 

4.4修改web.xml文件

打開demo工程的web.xml文件,向其中添加如下內容,讓spring也管理起來帶/service/的連接。

 

<servlet-mapping>

     <servlet-name>springmvc</servlet-name>

     <url-pattern>/service/*</url-pattern>

</servlet-mapping>

 

4.5 細節修改

打開editor-app/app-cfg.js, 將其中的「activiti-explorer」修改成「demo」。固然,具體項目中這裏可能會常常變化,咱們能夠寫一個js函數來自動獲取工程的名字,這樣之後將設計器集成到其餘工程的時候,就不須要修改這裏的內容了。作完這些操做以後,已經將activiti的頁面流程設計器集成到了demo項目中了,下面咱們編寫一些代碼作個測試

 

5.測試Activiti頁面流程設計器

在demo工程的src\main\java\org\activiti\rest\editor目錄下新建一個java文件,命名爲ModuleController,向其中加入如下內容。

 

import java.io.IOException;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.activiti.editor.constants.ModelDataJsonConstants;

import org.activiti.engine.ManagementService;

import org.activiti.engine.RepositoryService;

import org.activiti.engine.RuntimeService;

import org.activiti.engine.TaskService;

import org.activiti.engine.repository.Model;

import org.activiti.engine.repository.ProcessDefinition;

import org.activiti.engine.runtime.ProcessInstance;

import org.activiti.engine.task.Task;

import org.apache.commons.lang3.StringUtils;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

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.RequestParam;

import org.springframework.web.servlet.ModelAndView;

import com.fasterxml.jackson.databind.ObjectMapper;

import com.fasterxml.jackson.databind.node.ObjectNode;

 

@Controller

@RequestMapping("/model")

public class ModuleController {

 

private Logger logger = LoggerFactory.getLogger(ModuleController.class);

 

@Autowired

private RepositoryService repositoryService;

@Autowired

private RuntimeService runtimeService;

@Autowired

private TaskService taskService;

@Autowired

private ManagementService managementService;

 

@RequestMapping(value = "create")

public void create(@RequestParam("name") String name, @RequestParam("key") String key,

@RequestParam("description") String description, HttpServletRequest request, HttpServletResponse response) {

try {

ObjectMapper objectMapper = new ObjectMapper();

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);

Model modelData = repositoryService.newModel();

 

ObjectNode modelObjectNode = objectMapper.createObjectNode();

modelObjectNode.put(ModelDataJsonConstants.MODEL_NAME, name);

modelObjectNode.put(ModelDataJsonConstants.MODEL_REVISION, 1);

description = StringUtils.defaultString(description);

modelObjectNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION, description);

modelData.setMetaInfo(modelObjectNode.toString());

modelData.setName(name);

modelData.setKey(StringUtils.defaultString(key));

 

repositoryService.saveModel(modelData);

repositoryService.addModelEditorSource(modelData.getId(), editorNode.toString().getBytes("utf-8"));

 

response.sendRedirect(request.getContextPath() + "/modeler.html?modelId=" + modelData.getId());

} catch (Exception e) {

logger.error("建立模型失敗:", e);

}

}

}

 

而後將工程部署到tomcat下,啓動tomcat。訪問連接 http://localhost:8080/demo/model/create?name=test&key=test&description=testModel ,就能夠看到系統自動建立了一個流程,瀏覽器自動跳轉到設計器頁面。咱們就能夠在設計器頁面進行流程的設計了,你能夠查看數據庫,裏面已經添加了相應的數據記錄。

 

 

 

好長時間了,第一次寫博客,CSDN的編輯器居然不能直接從word裏面複製粘貼,排版都亂了,見諒微笑
