Abstract
Provided is a remote invocation method capable of reducing transmission flow. After a client is connected to a server through a control chain, RMI object information is obtained; the RMI object information is subjected to flow-saving serialization, and then, is transmitted to the server; and the server obtains original object information through deserialization to finish remote invocation. According to the method, by reducing the serialized flow, project information of a project where the object locates is not carried, thereby reducing use of network bandwidth and enabling the interaction speed of the client and the server to be improved by many times. Besides, for any place where the RMI method is adopted, the purpose of reducing the flow can be reached without making any modification in the method level.

At present, JavaRMI (RMI RemoteMethodInvocation) is a kind of mechanism, the method on the object in another Java Virtual Machine of object reference that can allow on certain Java Virtual Machine.This remote interface can must be realized with any object that the method is called.
After Client is connected to Server by Quality Initiative, obtain RMI object information [IP, PORT, ObjId], connected this [IP:Port] by Data-Link, send request and obtain the response of object corresponding to ObjID.
Transfer of data in all RMI, needs the serializing carrying out object, is delivered to server end, and server end can arrive original object information by unserializing.
RMI, when client end and server end carry out transfer of data, needs parameter to carry out serializing, and then at Internet Transmission, the size of this block serializing stream, directly affects the interactive speed of client and server end.
Summary of the invention
The object of the invention is to take many problems for method call flow in process, propose a kind of remote invocation method reducing delivery flow rate.
Technical scheme of the present invention is:
A kind of remote invocation method reducing delivery flow rate, after client Client is connected to server end Server by Quality Initiative, obtain RMI object information, RMI object information is carried out to the serializing of province's flow, be delivered to server end, server end can arrive original object information by unserializing, completes far call.
The present invention specifically comprises the following steps:
(1), client sends service request by IP and port to RMI server end;
(2), after RMI received server-side to the request of client, the IP of return service device end, the object ID of data transmission port and server end;
(3), client receives the IP that service end returns, and after data transmission port and object ID, can generate the local agent object of a RMI and local counterfoil Stub in client this locality;
(4), RMI client initiates corresponding request instruction by local agent object toward the RMI of server end, simultaneously can the method parameter of correspondence, and method name imports local agent object into;
(5), local agent object Stub by reflex mechanism, call invoke method, obtain the method parameter+method name of request object;
(6), after local agent object Stub gets the method parameter of corresponding object, first can obtain the channel C hannelConnection be connected with remote service end, then obtain the object output stream of this interface channel;
(7), get object output stream after, the serializing object method of local agent object reference JDK, changes into stream and writes in the object output stream that the 6th step gets by the method parameter sequence of the object got before;
(8), the information of object output stream in step (7) is sent to server end by client, after server receives request, first by the unserializing of JDK, stream unserializing is become corresponding requesting method parameter, then server end calls corresponding requesting method and carries out Business Processing;
(9), after server end method Business Processing terminates, result is changed into stream by JDK sequence, returns to RMI client, client is again by unserializing, and stream is read as corresponding result, then release connection, completes a RMI step.
Beneficial effect of the present invention:
RMI is when client end and server end carry out transfer of data, parameter is needed to carry out serializing, then at Internet Transmission, the size of this block serializing stream, directly affect the interactive speed of client and server end, when conventional process serializing stream, RMI is except carrying out serializing by the method parameter of object, also the engineering information of this object place project can be returned, these information include local classpath, local jar wraps path etc. information, these information are all the information of client local path, these information are utterly useless for our business, after but serializing is complete, but a large amount of bandwidth is occupied.The inventive method, by reducing the size of serializing stream, does not carry the engineering information of object place project, thus reduces the use of the network bandwidth, and the interactive speed that client and server is held promotes several times.In addition, the place of any use RMI method, without the need to making any amendment at method layer, can reach the object reducing flow.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, a kind of remote invocation method reducing delivery flow rate, after client Client is connected to server end Server by Quality Initiative, obtain RMI object information, RMI object information is carried out to the serializing of province's flow, be delivered to server end, server end can arrive original object information by unserializing, completes far call.The present invention specifically comprises the following steps:
(1), client sends service request by IP and port to RMI server end;
(2), after RMI received server-side to the request of client, the IP of return service device end, the object ID of data transmission port and server end;
(3), client receives the IP that service end returns, and after data transmission port and object ID, can generate the local agent object of a RMI and local counterfoil Stub in client this locality;
(4), RMI client initiates corresponding request instruction by local agent object toward the RMI of server end, simultaneously can the method parameter of correspondence, and method name imports local agent object into;
(5), local agent object Stub by reflex mechanism, call invoke method, obtain the method parameter+method name of request object;
(6), after local agent object Stub gets the method parameter of corresponding object, first can obtain the channel C hannelConnection be connected with remote service end, then obtain the object output stream of this interface channel;
(7), get object output stream after, the serializing object method of local agent object reference JDK, changes into stream and writes in the object output stream that the 6th step gets by the method parameter sequence of the object got before;
(8), the information of object output stream in step (7) is sent to server end by client, after server receives request, first by the unserializing of JDK, stream unserializing is become corresponding requesting method parameter, then server end calls corresponding requesting method and carries out Business Processing;
(9), after server end method Business Processing terminates, result is changed into stream by JDK sequence, returns to RMI client, client is again by unserializing, and stream is read as corresponding result, then release connection, completes a RMI step.
During concrete enforcement:
In the RMI communication process shown in Fig. 1, amendment the 3rd step sequence required parameter, original parameter comprises engineering information two parts of method parameter and object place project.The network packet analysis of client and the server transfer of data captured by network packet capturing is found, starting a few row is normal object serialization information, also has main frame ip.Major part is all some jar bag of the local project of client, the information of local classpath below, about 80% of the whole data flow that these information occupy, owing to being client local path information, server is held, utterly useless, if can remove these, so bandwidth usage will significantly reduce.
Therefore, get rid of the classPath serializing stream accounting for 80% size, the large young pathbreaker of whole serializing parameter stream reduces 4-5 doubly.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
