Fig. 1 is a kind of flow diagram for service calling method that the embodiment of the present invention one provides, and the present embodiment is applicable
When web browser or service client initiate the access request to service, pass through SOA (Service Oriented
Architecture, Services Oriented Achitecture) system call service the case where.Wherein SOA systems (i.e. SOA components) include
Client and server-side, client are produced with the software of existing web browser or service client deployment together
Product；Its server-side is that each server in server cluster corresponding with the web browser or service client is disposed
Software product together.This method can be executed by the client of SOA systems, be specifically comprised the following steps：
Step 110, the call request for receiving the corresponding with service that service client or browser are initiated by interface；
Step 120, at least two remote access addresses for obtaining service corresponding with interface；
Step 130, the long-range visit of selection one from least two remote access address according to the allocation algorithm of setting
Ask address, the remote access address as service institute corresponding with interface unique match；
Step 140 is based on hessian agreements and selected remote access address far call clothes corresponding with interface
Business.
In the present embodiment, service client or browser can initiate the call request of corresponding with service by interface, such as
A service invocation request is initiated by interface SOAFactory.getFactory () .getService (IService).
The client of SOA systems obtains at least the two of service corresponding with interface first after receiving the call request
A remote access address.When only existing a unique remote server and can realize the service, the service correspond to one it is remote
Journey access address.In the present embodiment, the server-side of SOA systems is corresponding with the web browser or service client remote
Together, there are at least two remote servers can realize the service for each server disposition in journey server cluster, i.e., should
Service corresponding at least two remote access address.Specifically obtaining the process of remote access address can be：It searches local
Configuration information in SOAProperties obtains at least two long-range visits of service corresponding with interface according to the configuration information
Ask address.Wherein, SOAProperties includes the pre-set remote access with the service corresponding to various interfaces of user
The configuration informations such as address.
Then, the client of SOA systems remotely accesses addresses according to the allocation algorithm of setting from acquired at least two
One remote access address of middle selection, the remote access address as service institute corresponding with interface unique match.Specific choosing
The process of selecting can be：One remote access address of selection from acquired at least two remote access addresses at random, as with

In order to improve the success rate of service call, in follow-up service calling process, the client of SOA systems can be real
When or by predetermined period detection with it is selected remotely access address unique match service whether can be used, if it is not then
It is the remote access address that service corresponding with interface reselects a unique match again.
Certainly, the allocation algorithm of setting, can also be according to its other party such as type for the service called in addition to being randomly assigned
Formula is allocated, for example, SOA systems client when receiving the service invocation request of an interface, the clothes can be analyzed first
The service type being engaged in belonging to call request, then according between multiple access address under preset service type and the interface
Mapping relations select a remote access address corresponding with the service type analyzed, as this service call
When corresponding with interface service institute unique match remote access address.
Behind the remote access address for obtaining service institute corresponding with interface unique match, the client of SOA systems is based on
Hessian agreements and the service corresponding with interface of selected remote access address far call.The server-side of SOA systems is connecing
After the far call request for receiving the client of SOA systems, respective service is obtained from the server together with its subordinate, and will
Client of the service through SOA systems is issued to web browser or service client.Hessian is the remote of lightweight
Journey service access tool provides RMI (Remote Method Invocation, remote method call) using simple method
Function.Compared to WebService, Hessian is simpler, quick.Hessian agreements are using binary system RPC (Remote
Procedure Call, remote procedure call) agreement, it is well suited for sending binary data.
On the one hand the technical solution that the present embodiment proposes remotely is visited by obtaining at least two of service corresponding with interface
It asks address, and remote service calling is carried out according to the remote access address chosen from these remote access addresses, it can
When realizing that initiating a large amount of concurrent invocation for client asks, accessed in remote server cluster by rational distribution principle
Different server to carry out service call, substantially increase the stability and reliability of strange land service call mechanism；Another party
Corresponding with interface service is called in face by being based on hessian protocol remotes, since Hessian agreements are simplified and efficiently,
