Bonita Client.jar提供的rest 访问方法

Bonita studio提供导出bonita-server-rest.war 的方法，然后你的客户端程序完全可以通过rest来访问bonita服务器提供的引擎服务

具体方法如下

 

 

1. 读取参数 ，设置启动时读取参数文件

 

     1>web.xml的设置

             <servlet>
              <servlet-name>InitBonitaClientUtil</servlet-name>
              <servlet-class>com.company.bonita.admin.web.InitBonitaClientUtil</servlet-class>
            <load-on-startup>3</load-on-startup>
        </servlet>
