activiti自定义流程之整合（一）：整体环境配置-阿里云开发者社区

结合之前所说的自定义流程的思路，分别是后台、前台、整合，之前的内容也分别进行了相关的练习和尝试，现在就该到了最后的整合了，依旧是以实现功能为目的，细节暂且不去管他。

因为我们实际项目后端用的是spring、spring mvc、mysql、mybatis，前台用的angular js，因此在整合时我也自己搭建使用了这样的环境。

1、所使用的环境基础：eclipse4.4、mysql5.6、angularjs1.4、tomcat7、jdk1.7、maven3.2、spring4.0.9、activiit5.16、activiti-modeler5.16

2、后端maven导包pom.xml文件如下：

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

</project>

3、 web项目基础配置web.xml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>字符集过滤器</description>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<description>字符集编码</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>

4、其他依赖环境，如下图中红线框起来的部分：其中包括使用angularjs依赖的js，整合activiti-modeler依赖的文件和使用ueditor插件所需的文件。（具体的文件可参考之前的博客内容）

5、后台spring基础配置文件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"

	<bean id="formService" factory-bean="processEngine" factory-method="getFormService" />
     <bean id="IdentityService" factory-bean="processEngine" factory-method="getIdentityService" />
    <!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->
	<bean id="mappingJacksonHttpMessageConverter"

		<property name="supportedMediaTypes">

	</bean>


	<!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
	<bean

		</property>
	</bean>
    
</beans>
