Acticiti in startProcessInstanceByKey Method in variable How to store in the table

It is known that :

In the use of runtimeService.startProcessInstanceByKey(String processDefinitionKey, String businessKey, Map<String, Object> variables) When initiating a process , Business data needs to be stored in act_hi_varinst( The process is over ) And act_ru_variable( Process not ended ) In these two tables . Here's the picture :

• NAME_: Store the field names in the business table
• VAR_TYPE Stored as field type
• BOUBLE\_,LONG\_,TEXT_ Store field values

When JAVA There are properties of the following types in the class, such as :List And so on

stay varinst As shown in the following figure , From the figure below activiti take list Data of collection type is serialized to act_ge_bytearray In the table

Go to the act_ge_bytearray Find the corresponding id You can find the corresponding serialized storage , But at this time, it is found that there are two different types of names NAME_, Here's the picture :

• With hist.var The beginning represents historical variables , Delegate process ended
• With var The beginning represents that the process is running
