具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
本发明实施例提供区块链中多联盟链的负载均衡方法所适用的系统架构，该系统架构可以包括多个机构，多个机构中各个机构的节点组成联盟链以及路由链，示例性的，可以如图1所示，该系统包括机构A、机构B、机构C，其中，机构A包括节点A1、节点A2、节点A3、节点A4，机构B包括节点B1、节点B2、节点B3、节点B4，机构C包括节点C1、节点C2、节点C3。节点A1、节点A4、节点B1、节点C1组成联盟链1，节点A2、节点B2、节 点B4、节点C2组成联盟链2，节点A3、节点B3、节点C3组成路由链。
本发明实施例中，路由链是由多联盟链中的机构的节点组成的区块链，路由链的合约信息包括一个路由配置文件，即各机构共同维护一个路由配置文件，该路由配置文件中包括各机构的路由规则，如图1，机构A、机构B、机构C确定路由链的合约信息，共同维护一个路由配置文件，该路由配置文件包括机构A的路由规则、机构B的路由规则、机构C的路由规则。若某个机构接收到业务请求之后，会根据路由链的合约信息确定出应该将该业务请求发送至哪一个联盟链中，从而实现多联盟链的负载均衡。
基于上述描述，图2示例性的示出了本发明实施例提供的一种区块链中多联盟链的负载均衡方法的流程，该流程可以由区块链中多联盟链的负载均衡装置执行。如图2所示，该流程具体包括：
步骤201，获取业务请求和路由链的合约信息。
本发明实施例中，业务请求可以包括以下参数中的任一项或组合：待处理业务、机构标识、业务标识和序列号。其中，机构标识即业务请求中待处理业务对应机构的标识，业务标识即该业务请求中待处理业务的业务标识，序列号为该待处理业务的序列号。结合图1，若机构A获取到一个业务请求，该业务请求中待处理业务对应的机构为机构A，则机构标识为“Org A”，该业务请求中的待处理业务的业务标识为“APPID A1”、序列号为“SeqNo 50”，则可以理解为，该业务请求中包括“Org A，APPID A1、SeqNo 50”。
本发明实施例中，路由链的合约信息可以包括以下参数中的任一项或组合：各机构的路由规则、各机构的节点、各联盟链的节点。各机构的路由规则包括各机构的业务标识、序列号的范围和联盟链标识，各机构的节点即各机构包含的节点，各联盟链的节点即各联盟链包含的节点。示例性的，如图1所示的架构中，各机构的路由规则可以参照表1所示，各机构的节点可以参照表2所示，各联盟链的节点可以参照表3所示。 表1

本发明实施例中，机构可以从路由链获取路由链的合约信息，机构发送合约信息获取请求至路由链的节点，路由链的节点接收到该合约信息获取请求后，将路由链的合约信息反馈至机构，机构接收该路由链的节点反馈的路由链的合约信息。
步骤202，根据所述业务请求和路由链的合约信息，确定所述业务请求对应的联盟链。
本发明实施例中，路由链的合约信息可以包括各机构的路由规则，业务请求包括机构标识、业务标识和序列号，具体的，先根据机构标识、各机构的路由规则，确定业务请求所属机构的路由规则，再根据业务标识和序列号，查询业务请求所属机构的路由规则，确定出业务请求对应的联盟链。
本发明实施例中，机构可以获取到待处理业务是本机构的业务请求，也可以获取到待处理业务不是本机构的业务请求，即机构A可以获取到机构标识为“Org A”的业务请求，也可以获取到机构标识为“Org B”的业务请求。
示例性的，若机构A获取到的业务请求包括“Org A，APPID A1、SeqNo50”，则可以根据“Org A，APPID A1、SeqNo 50”和表1确定出联盟链标识为Chain1，即该业务请求对应联盟链1。或者，若机构A获取到的业务请求包括“Org B，APPID B1、SeqNo 50”，则可以根据“Org B，APPID B1、SeqNo50”和表1确定出联盟链标识为Chain2，即该业务请求对应联盟链2。
步骤203，根据所述业务请求对应的联盟链确定第一节点，并将所述待处理业务发送至所述第一节点。
本发明实施例中，第一节点为多联盟链中用于处理待处理业务的节点。 也就是说，在步骤202中确定出业务请求对应的联盟链后，需要从该业务请求对应的联盟链中确定出处理该待处理业务的节点，该节点即为第一节点。
可选的，路由链的合约信息包括各机构的节点、各联盟链的节点，业务请求包括机构标识，先根据业务请求对应的联盟链、各联盟链的节点，确定业务请求对应的联盟链的节点的第一集合；再根据机构标识、各机构的节点，确定业务请求所属机构的节点的第二集合；最后根据属于第一集合且属于所述第二集合的节点，确定第一节点。
解释为，在确定出业务请求对应的联盟链后，可以根据表3确定出业务请求对应的联盟链的节点，根据表2确定出业务请求对应的机构的节点。例如，根据“Org A，APPID A1、SeqNo 50”和表1确定出业务请求对应联盟链1后，确定联盟链1的节点组成的第一集合为“节点A1、节点A4、节点B1、节点C1”，确定机构A的节点组成的第二集合为“节点A1、节点A2、节点A3、节点A4”，同属于第一集合、第二集合的节点为“节点A1、节点A4”，根据“节点A1、节点A4”确定出第一节点，此处可知，属于第一集合且属于第二集合的节点可以为一个或者大于一个，当属于第一集合且属于第二集合的节点为一个，则将该唯一一个节点确定为第一节点，当属于第一集合且属于第二集合的节点为大于一个时，可以从该大于一个的节点中随机确定出第一节点，也可以根据预先设定的规则确定，在此不做限定。
此外，节点可以包括节点所对应的IP地址和监听端口，在确定出第一节点后，可以根据第一节点的IP地址和监听端口，将待处理业务发送至第一节点，以使得第一节点对该待处理业务进行处理。
本发明实施例中，还可以对路由链的合约信息进行修改，进一步的，可以对各机构的路由规则进行修改，具体的，获取路由规则的修改信息，将路由规则的修改信息发送至路由链的节点，以使路由链的节点根据路由规则的修改信息对路由链的合约信息进行修改。例如，需要对机构B的路由规则进行修改，将APPID B1的序列号范围为“100～200”所对应的联盟链修改为联盟链1，则可以直接在机构B中修改，并将修改信息发送至路由链的节点， 如图1，可以发送至节点B3，节点B3根据该修改信息对路由链的合约信息进行修改。
为了更好的解释本发明实施例，下面将在具体的实施场景下描述该多联盟链的负载均衡流程，如图3所示，具体如下：
步骤301，机构获取业务请求；
步骤302，机构发送合约信息获取请求至路由链节点；
步骤303，路由链节点发送路由链的合约信息至机构；
步骤304，机构根据业务请求和路由链的合约信息，确定业务请求对应的联盟链；
步骤305，机构根据业务请求对应的联盟链确定第一节点；
步骤306，机构发送待处理业务至第一节点；
步骤307，第一节点处理待处理业务。
由于本实施例的具体实现方式已在其他实施例中描述，在此不作赘述。
本发明提供的另一个实施例可以如图4所示，其中，该系统中还可以包括proxy(代理服务器)，该proxy可以位于机构中，也可以独立于机构，proxy用于代理机构完成上述区块链中多联盟链的负载均衡方法，具体的，机构获取到业务请求后，将业务请求发送至proxy，proxy读取路由链中的合约信息，根据合约信息从多联盟链中确定出与该业务请求相对应的联盟链，该业务请求相对应的联盟链处理该业务请求中的待处理业务，并将业务成功的结果反馈至proxy，proxy向机构响应执行结果。
上述技术方案中，获取业务请求和路由链的合约信息，其中，路由链是由多联盟链中的机构的节点组成的区块链，路由链的合约信息是由多机构共同维护的，也就避免出现各机构路由配置文件不一致的问题，进一步根据业务请求和路由链的合约信息，即可以确定出业务请求对应的联盟链，并在确定出第一节点后，将待处理业务发送至第一节点，该方式确定出的业务请求对应的联盟链以及第一节点可有效达到多联盟链的负载均衡，即通过多机构共同维护一个路由链的合约信息，避免出现由于各机构的路由规则不一致， 导致无法实现多联盟链的负载均衡。
