initializelong com.opensymphony.workflow.AbstractWorkflow.initialize(String workflowName, int initialAction, Map inputs) throws InvalidRoleException, InvalidInputException, WorkflowException初始化步骤：1.获取存储配置（jdbc）WorkflowDescriptor wf = getConfiguration().getWorkflow(workflowName);WorkflowStore store = getPersistence();2.创建条目（insert into OS_WFENTRY）WorkflowEntry entry = store.createEntry(workflowName);3.初始化PropertySetkey=osff_+entryId、参数=propertyset.xml配置PropertySet ps = store.getPropertySet(entry.getId());4.填充transientVarspopulateTransientMap(entry, transientVars, wf.getRegisters(), new Integer(initialAction), Collections.EMPTY_LIST, ps);5.检查是否满足初始化条件if (!canInitialize(workflowName, initialAction, transientVars, ps)) {context.setRollbackOnly();throw new InvalidRoleException("You are restricted from initializing this workflow");}6.获取初始化actionActionDescriptor action = wf.getInitialAction(initialAction);7.流转工作流transitionWorkflow(entry, Collections.EMPTY_LIST, store, wf, action, transientVars, inputs, ps);8.返回IDlong entryId = entry.getId();doActionvoid com.opensymphony.workflow.AbstractWorkflow.doAction(long id, int actionId, Map inputs) throws WorkflowException执行动作：1.在全局action中找到指定action。2.在全局action中找不到就到当前步骤中找指定action。3.流转工作流。transitionWorkflowboolean com.opensymphony.workflow.AbstractWorkflow.transitionWorkflow(WorkflowEntry entry, List currentSteps, WorkflowStore store, WorkflowDescriptor wf, ActionDescriptor action, Map transientVars, Map inputs, PropertySet ps) throws WorkflowException1.清空ThreadLocal中的状态缓存；2.通过传入参数Action取得当前Step；3.检查输入验证；4.获取当前Step的PostFunction，并执行；5.执行当前Action的preFunction，并执行；6.获取满足条件的Result；7.执行当前Result的preFunction，并执行；8.如果Result的Split不为空，执行Splist的Result；9.如果Result的Join不为空，执行（结束当前步骤，移动到历史步骤，找到所有join步骤放入“jn”，执行条件，执行Result。）；10.执行未执行的PostFunction；11.执行自动action。
