Problems solved by technology

The advantage of this analysis method is to clarify the specific analysis method or function of each proposed protocol. If the program analysis module makes an error, it will be easy to locate or correct the error. It is not related to other protocols, but relatively for multi-part protocols need to write The analysis method or function of N protocols is also quite high for later maintenance and expansion costs

Embodiment

[0035] Such as figure 1 As shown, the network communication data packet analysis method of the present embodiment includes the following steps:

[0036] Step 1. Define the basic data type enumeration DataType, extended enumeration, etc. DataType中字段包含dt_UINT8、dt_INT8、dt_UINT16、dt_INT16、dt_UINT32、dt_INT32、dt_UINT64、dt_INT64、dt_FLOAT、dt_DOUBLE、dt_ASCII、dt_BOOLEAN、dt_UINT8_ARRAY、dt_INT8_ARRAY、dt_UINT16_ARRAY、dt_INT16_ARRAY、dt_UINT32_ARRAY、dt_INT32_ARRAY、dt_UINT64_ARRAY、dt_INT64_ARRAY、dt_FLOAT_ARRAY、dt_DOUBLE_ARRAY、dt_NONE;

[0037] Step 2. Create the annotation class DataColumn, Target specifies the range of objects modified by the annotation @Target(ElementType.FIELD), and Retention specifies the length of time the annotation is retained @Retention(RetentionPolicy.RUNTIME). Define the basic field attributes of annotations, field attributes include data type dataType data type enumeration default value is dt_NONE, length data length default value is 0 (general string ASCII needs ...

Abstract

The present invention discloses a network communication data packet analysis method. The method comprises the following steps: S1, editing custom annotations; S2, editing the corresponding logic processing according to the content defined by the custom annotations, and packaging the corresponding logic processing as a 'data conversion class'; S3, editing the data entity class of the protocol according to the protocol structure of the protocol; and S4, calling the 'data conversion class', loading the data entity to be analyzed, reflecting the corresponding information in the data entity class, and calling the corresponding logic processing according to the information to output the analysis result. The network communication data packet analysis method based on Java language employs the custom annotations and the reflection mechanism of the Java, the annotations can be infinitely extended to realize corresponding functions according to the extended annotations so as to greatly improve the expansibility, the binding force and the flexibility and simplify the complexity.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for analyzing network communication data packets based on the Java language. Background technique [0002] The widespread use of computer systems and networks has brought the world into the information age. However, just because almost everything in modern society is "computerized", such as the management of economic activities (production, circulation, exchange, consumption, etc.) ", that is to say, they are all running based on "software (program)", but from another perspective, if software needs to communicate with each other, it must interact through a huge "network". The language in the "network" is just like we usually do in life. An agreement is drawn up in advance, what kind of word combination represents what kind of meaning, and the language in the "network" is no exception. Here we want to mention It is a method of analyzing network language (network dat...
