Embodiment 1

[0082] This embodiment provides a method for data communication between multi-level servers. This embodiment is the first server-side processing method, such as figure 2 shown, including the following steps:

[0083] S1: the first server connects to the second server through the connection interface of MINA. The first server can be connected to one or more servers through the connection interface of MINA. In this embodiment, one server, that is, the second server, is used as an example.

[0084] S2: The first server sends an interface command, and encapsulates the command information to obtain information in a first format.

[0085] The interface command is a call command, that is, the first server calls the information of the second server. At this time, the first server is an upper-level server, and the second server is a lower-level server. For example, a province has three levels of platforms: provincial level, city level, and county level. The provinces and cities are ...

Embodiment 2

[0096] This embodiment provides a method for data communication between multi-level servers. This embodiment is the first server-side processing method, such as image 3 shown, including the following steps:

[0097] S1: the first server connects to the second server through the connection interface of MINA. The first server can be connected to one or more servers through the connection interface of MINA. In this embodiment, one server, that is, the second server, is used as an example.

[0098] S2: The first server sends an interface command, and encapsulates the command information to obtain information in a first format.

[0099] The interface command is a push command, that is, the first server pushes information to the second server. At this time, the first server is a lower-level server, and the second server is a higher-level server. For example, a province has three levels of platforms: provincial, municipal, and county. The provinces and cities are connected, and th...

Embodiment 3

[0108] This embodiment provides a method for data communication between multi-level servers. This embodiment is a second server-side processing method, such as Figure 4 shown, including the following steps:

[0109] T1: The second server connects to the first server through the connection interface of MINA, and saves the corresponding connection after the connection is successful.

[0110] T2: The second server receives the interface command and the second format information sent by the first server through the receiving interface of the MINA, where the interface command is a calling command.

[0111] T3: The second server deserializes the information in the second format into information in the third format. Deserializing the information in the second format into the information in the third format uses the Xstream technology, and the Xstream technology is as described in Embodiment 1. The information in the third format is information in JavaBean format.

[0112] T4: The...

Abstract

The present invention provides a data communication method among multi-level servers and a server. The first server connects to the second server through the connection interface of MINA. After the connection is successful, the interface command is sent to obtain the first format information, and the first format information object is serialized as After the XML format is sent to the second server through the sending interface of MINA, the second server deserializes the information after receiving the XML format information, and performs parsing to obtain the result. It realizes the remote call and active push function between multi-level servers, and the MINA-based application program framework is simple and has good performance. The underlying communication is communicated in XML format, which provides the possibility for future cross-language calls or pushes.

Description

technical field [0001] The invention relates to the technical field of a distributed system, in particular to a data communication method among multi-level servers and a server. Background technique [0002] At present, the construction of large-scale distributed systems usually uses the abstraction of "layer": "layer" may be a "layer" in a multi-layer architecture, or a component in a component system, or a Service-Oriented Architecture (Service-Oriented Architecture, SOA ), in which the system is divided into multiple "layers", and interfaces need to be defined between each layer for information exchange. In a distributed cascade system, a server is deployed at each level of the province, city, and county. The upper-level server can call the lower-level server, and at the same time, the lower-level server can actively push information to the upper level, such as figure 1 As shown, after the servers are connected, the top-level server can be connected as the first server o...
