Fig. 1 shows a kind of flow diagram of the transaction methods of Distributed Architecture provided in an embodiment of the present invention.
As shown in Figure 1, the transaction methods of Distributed Architecture provided in an embodiment of the present invention, the method specifically include
Following steps:
Step 101, after detecting that first unit receives process exception message, the subelement of the first unit is obtained；
Wherein, the first unit executes a destination service, and each subelement executes the sub-services of a destination service, and institute
Sub-services are stated with execution order.
Wherein, first unit is any service unit in Distributed Architecture.First unit executes a destination service, and the mesh
Mark service include at least two sub-services, two sub-services respectively by first unit subelement execute, and each sub-services it
Between have execution order.Optionally, each unit or the institutional framework (relationship between superior and subordinate between node) of subelement pass through
Spring configuration file is configured；The scheduling of each unit or subelement is by Spring towards tangent plane programming (Aspect
Oriented Programming, AOP) it realizes.
After process exception occurs in subelement, subelement is by process exception message to being thrown off to first unit.If distribution
Formula frame detects that first unit receives process (process) unexpected message from its subelement, obtains first unit packet
The subelement included, to determine the generation position of process exception.
As the first example, referring to fig. 2, Fig. 2 show the Distributed Architecture of a tree structure, wherein using unit 3 as
For first unit, unit 3 executes a destination service, and the destination service includes 3 sub-services, respectively by unit 4, unit 5
And unit 6 executes, and execution sequence is followed successively by unit 4, unit 5, unit 6；If unit 3 is received from unit 4, unit 5
Or the process exception message of unit 6, then the subelement information of Distributed Architecture acquiring unit 3.
Step 102, according to the execution order, backward executes rollback to the subelement, determines that the process exception disappears
Cease corresponding target subelement.
Wherein, rollback (Rollback) refers to program or data processing mistake, program or data is restored to last correct
The behavior of state.After determining the subelement that first unit includes, sequence is executed according to what each subelement was configured, backward is to each
Subelement carries out rollback, that is, executes the process of service or sub-services, and the execution order that each unit or subelement configure inversely performs,
Rollback is inversely carried out when occurring abnormal, and during rollback, determines the corresponding target subelement of process exception message, i.e.,
The position that process exception occurs.
With continued reference to Fig. 2, rollback is carried out to the subelement of unit 3, then rollback order is successively are as follows: unit 6, unit 5, unit
4。
Step 103, determine the object invocation program for calling the target subelement, by the process exception message dish out to
The object invocation program.
Wherein it is determined that further determining that after the target subelement of generation process exception and calling the target subelement
Object invocation program dishes out process exception message to the object invocation program, knows that target is single convenient for object invocation program
Process exception occurs for member, and treatment progress is abnormal in time.
In the above embodiment of the present invention, after detecting that first unit receives process exception message, it is single to obtain described first
The subelement of member；The execution order of sub-services is executed according to subelement, backward executes rollback to the subelement, described in determination
The corresponding target subelement of process exception message, and further determine that the object invocation program for calling the target subelement, it will
The process exception message is dished out to the object invocation program；The embodiment of the invention provides a kind of processing distributed type assemblies rings
The mode of service exception problem in border, to ensure the integrality of affairs in Distributed Architecture；It is single for each unit or son simultaneously
Member provides flexible rollback configuration, can be automatically controled trouble unit when breaking down and carries out rollback, and to being thrown off process
Unexpected message is abnormal convenient for the timely treatment progress of object invocation program.
Optionally, in the embodiment of the present invention, described according to the execution order, backward executes rollback to the subelement
Step, comprising:
According to the execution order, backward obtains the default execution parameter of the subelement, and the default execution parameter is used
The process of corresponding sub-services whether has been executed in the instruction subelement；
If the default execution parameter indicates that the subelement is not carried out the process, skips the subelement and obtain
The default execution parameter of next subelement；
If the default execution parameter indicates that the subelement has executed the process, the subelement is executed back
Rolling, and obtain the default execution parameter of next subelement.
Wherein, it presets execution parameter and is used to indicate the process whether subelement has executed corresponding sub-services, right
During subelement carries out rollback, judged whether according to default execution parameter to each subelement process rollback；If default hold
Row parameter indicates that current subelement is not carried out the process, then skips the subelement, not to the subelement process rollback, and continue
Judge whether next subelement needs rollback, obtains the default execution parameter of next subelement；Conversely, if default execute ginseng
Number indicates that current subelement has executed the process, then executes rollback to the subelement, and continue to judge next subelement
Whether rollback is needed, obtains the default execution parameter of next subelement.
In above-described embodiment, support section subelement rollback, due in distributed type assemblies environment, when the processing of whole flow process
Between it is longer, it is larger to be related to data volume, after exception occurs in one link in centre, can not have to entire link and carry out rollback, only
Currently there is abnormal unit in rollback.
Referring to fig. 2, process abnormal (i.e. process exception) is that unit 5 occurs, and unit 6 is not carried out at this time, in rollback
During, it can judge whether active cell has executed according to the default parameter that executes, can be skipped if being not carried out, is i.e. unit 6
Rollback method will not be executed really.After the completion of 3 rollback of unit, can front unit 5 occur abnormal to being thrown off, throw
It gives top-ranked unit (General Init unit), the top-ranked unit exception can be thrown to the program of calling (is dished out
PaaSException)。
As another implementation, first unit can be also arranged to automatic rollback unit, even first unit is connecing
It receives its subelement to dish out after process exception message, rollback processing can be carried out automatically.As shown in Fig. 2, occurring in unit 5
Process is abnormal, and 5 superior node of unit is dished out process exception information；After unit 3 receives process exception, due to
Unit 3 is automatic rollback unit, and can all subelements of unit 3 be carried out with rollback, and execution sequence is as follows: unit 6, unit 5, list
Member 4.
