相比eclipse安装activit插件之后直接创建activiti项目的简便，IDEA创建activiti工作流项目较为麻烦

activiti项目的本质是maven项目，IDE直接创建maven项目 之后需要手动添加maven配置进入pom.xml

以下是我的pom文件配置，有需要可以直接粘贴使用

        </build>
    
    </project>

值得注意的是，在使用classpath加载资源文件时，eclipse等是自动加载resource文件下的资源，而IDEA则需要手动去指定识别,我在 pom中指定了<build>节点下过滤所有文件为资源文件，将所有resources文件都可以访问到

<resource>  
                <directory>src/main/resources</directory>  
                <includes>  
                    <include>\*\*/\*.yml</include>  
                    <include>\*\*/\*.xml</include>  
                    **<include>\*\*/\*.\*</include>**

</includes>  
                <filtering>false</filtering>  
            </resource>  
最后说一句myeclipse很垃圾，eclipse老版很可靠，新版各种问题，IDEA有很多逻辑上的反常识
