activiti其中数据的查询和判断都是类似的！在这里就不过多介绍了。
下面是actviti中mybatis的映射配置：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <settings> <setting name="lazyLoadingEnabled" value="false" /> </settings> <typeAliases> <typeAlias type="org.activiti.engine.impl.persistence.ByteArrayRefTypeHandler" alias="ByteArrayRefTypeHandler"/> </typeAliases> <typeHandlers> <typeHandler handler="ByteArrayRefTypeHandler" javaType="org.activiti.engine.impl.persistence.entity.ByteArrayRef" jdbcType="VARCHAR"/> </typeHandlers> <mappers> <mapper resource="org/activiti/db/mapping/entity/Attachment.xml" /> <mapper resource="org/activiti/db/mapping/entity/ByteArray.xml" /> <mapper resource="org/activiti/db/mapping/entity/Comment.xml" /> <mapper resource="org/activiti/db/mapping/entity/Deployment.xml" /> <mapper resource="org/activiti/db/mapping/entity/Execution.xml" /> <mapper resource="org/activiti/db/mapping/entity/Group.xml" /> <mapper resource="org/activiti/db/mapping/entity/HistoricActivityInstance.xml" /> <mapper resource="org/activiti/db/mapping/entity/HistoricDetail.xml" /> <mapper resource="org/activiti/db/mapping/entity/HistoricProcessInstance.xml" /> <mapper resource="org/activiti/db/mapping/entity/HistoricVariableInstance.xml" /> <mapper resource="org/activiti/db/mapping/entity/HistoricTaskInstance.xml" /> <mapper resource="org/activiti/db/mapping/entity/HistoricIdentityLink.xml" /> <mapper resource="org/activiti/db/mapping/entity/IdentityInfo.xml" /> <mapper resource="org/activiti/db/mapping/entity/IdentityLink.xml" /> <mapper resource="org/activiti/db/mapping/entity/Job.xml" /> <mapper resource="org/activiti/db/mapping/entity/Membership.xml" /> <mapper resource="org/activiti/db/mapping/entity/Model.xml" /> <mapper resource="org/activiti/db/mapping/entity/ProcessDefinition.xml" /> <mapper resource="org/activiti/db/mapping/entity/Property.xml" /> <mapper resource="org/activiti/db/mapping/entity/Resource.xml" /> <mapper resource="org/activiti/db/mapping/entity/TableData.xml" /> <mapper resource="org/activiti/db/mapping/entity/Task.xml" /> <mapper resource="org/activiti/db/mapping/entity/User.xml" /> <mapper resource="org/activiti/db/mapping/entity/VariableInstance.xml" /> <mapper resource="org/activiti/db/mapping/entity/EventSubscription.xml" /> </mappers> </configuration>
下面是就那其中一个映射配置来说明，如HistoricProcessInstance.xml：
<?xml version="1.0" encoding="UTF-8" ?>

看了这些，如果你觉得你对activiti的底层有足够的了解，你可以完全重写或者扩展actviti中的service API。activiti就是通过这些sql映射配置来完成数据查询，当然如果你在使用过程中如果发现其中一些sql查询效率很低的话，大伙可以由针对的进行修改达到自己的要求。 现在网络上一些关于activiti也有类似的问题出现。大伙使用过程相信也会遇到。在这里就这样抛砖引玉，希望对初学的你有所帮助.......
