The application discloses a COBOL-to-Java program conversion method and system based on a syntax tree, belongs to the technical field of computer program language conversion, and comprises the following steps: obtaining a COBOL source program file to be converted and configuration rules; performing lexical analysis and syntax analysis to generate an abstract syntax tree; converting COBOL syntax elements into corresponding Java semantic representations according to pre-defined semantic mapping rules; establishing an accurate access chain of a main program and COPYBOOK internal variables through variable path tracking; detecting and solving naming conflicts of COBOL different-level same-name variables based on a scope tree, and renaming variables by adding a parent class name prefix; and generating the converted Java semantic representations into a Java source code file. The application realizes high-fidelity and high-automation COBOL-to-Java conversion, significantly reduces the migration cost of a legacy system, and generates code with strong readability and excellent performance.

The invention discloses a Cobol code conversion deployment method and device and a medium, and the method comprises the steps: receiving an original Cobol code, carrying out the standardization processing of the original Cobol code, outputting a standardized Cobol code, carrying out the partition structural analysis of the standardized Cobol code, and obtaining a target parsedredge data structural body; respectively generating a Java public code part and a Java service code part by adopting a preset conversion tool and a preset large model based on the target parsedredge data structure body, and combining to obtain a target Java engineering code; according to the technical scheme, the target Jar package is obtained after the target engineering code is compiled and packaged, finally, the target Jar package is deployed into the target environment through the preset deployment platform, and the technical problems of poor Cobol code conversion precision and low efficiency in related technologies are solved through standardized processing, partition structured analysis, code collaborative generation and compilation deployment.

An object of a system according to an embodiment is to efficiently convert a COBOL code of a legacy system into a Java code.SOLUTION: A system includes a COBOL code analysis unit, a conversion unit, and an optimization unit. The COBOL code analysis unit analyzes a COBOL code. The conversion unit converts the COBOL code analyzed by the COBOL code analysis unit into Java code. The optimization unit optimizes the Java code converted by the conversion unit.SELECTED DRAWING: Figure 1
