异常摘要 | |
---|---|
ActivitiClassLoadingException | Runtime exception indicating the requested class was not found or an error occurred while loading the class. |
ActivitiException | Runtime exception that is the superclass of all Activiti exceptions. |
ActivitiIllegalArgumentException | An exception indicating that an illegal argument has been supplied in an Activiti API-call, an illegal value was configured in the engine's configuration or an illegal value has been supplied or an illegal value is used in a process-definition. |
ActivitiObjectNotFoundException | An exception indicating that the object that is required or actioned on does not exist. |
ActivitiOptimisticLockingException | Exception that is thrown when an optimistic locking occurs in the datastore caused by concurrent access of the same data entry. |
ActivitiTaskAlreadyClaimedException | This exception is thrown when you try to claim a task that is already claimed by someone else. |
ActivitiWrongDbException | Exception that is thrown when the Activiti engine discovers a mismatch between the database schema version and the engine version. |
JobNotFoundException | This exception is thrown when you try to execute a job that is not found (may be due to cancelActiviti="true" for instance).. |
Public API of the Activiti engine.
Typical usage of the API starts by the creation of a ProcessEngineConfiguration
(typically based on a configuration file), from which a ProcessEngine
can be obtained.
Through the services obtained from such a ProcessEngine
, BPM and workflow operation
can be executed:
RepositoryService
: Manages Deployment
s
RuntimeService
: For starting and searching ProcessInstance
s
TaskService
: Exposes operations to manage human (standalone) Task
s,
such as claiming, completing and assigning tasks
IdentityService
: Used for managing User
s,
Group
s and the relations between them
ManagementService
: Exposes engine admin and maintenance operations,
which have no relation to the runtime exection of business processes
HistoryService
: Exposes information about ongoing and past process instances.
FormService
: Access to form data and rendered forms for starting new process instances and completing tasks.
