Abstract

Embodiments of the present application provide a code compilation method and apparatus, which relate to the technical field of data processing. The method comprises the following steps: obtaining a Java bytecode to be compiled in a Java class file; Compiling the Java bytecode to be compiled into an intermediate expression to be compiled; Obtaining an analysis result according to the analysis of the intermediate expression to be compiled; According to the analysis results, the multi-line code in the intermediate expression to be compiled is compiled into one-to-one corresponding multi-line CPPcode line by line. Because the CPP code is difficult to be analyzed, the Java bytecode is finally converted into many lines of CPP code to run, which improves the security and solves the technical problem that the security of the user can not be guaranteed due to the very easy reverse analysis of the attacker of the Java code.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a method and apparatus for compiling code. Background technique [0002] At present, as a widely used computer programming language, Java has the characteristics of cross-platform, object-oriented, generic programming, etc. It has been widely used in various application development. [0003] The Java code can be run on the Java virtual machine after being compiled and released directly. However, since Java has a logical and complete description document, the Java code is very easy to be reversely analyzed by the attacker, resulting in the security for the user cannot be guaranteed. SUMMARY OF THE INVENTION [0004] The present application is to provide a method and apparatus for compiling code to effectively improve the above-mentioned defects. [0005] In order to achieve the above purpose, the embodiments of the present application are achieved in the...
