Param values added to customProps map will be parse as activiti global variable.
So if you had added PARAM_TASK_STATE into process instances global variable in you workflow,you can query using customProps

I have received message from Kaynezhang !

This is his solution , and my problem has resolve .

The brief process is like below:
1.Whenever state changing task such as "Start Review", "In Review", "Approved", "Rejected" is executed,persiste process variables (for example PROCESS_STATE) into database.

execution.setVariable("PROCESS_STATE",state);

2.Get workflow instances according to the state(global variables)

WorkflowInstanceQuery workflowInstanceQuery = new WorkflowInstanceQuery();

Map<QName, Object> customProps = new HashMap<QName, Object>(9);

workflowInstanceQuery.setCustomProps(customProps);

workflowService.getWorkflows(workflowInstanceQuery);
