baifan/dynamic-compiler

Hot compile java source file, and analysis which classes and methods are called.

Dynamic Compile Java && Check byte code

1. Dynamic compile java source file to byte codes.
2. Check which classes and methods are called in the byte codes.

Project Usage

Build

To build the project:

$ git clone git@github.com:baifan/dynamic-compiler.git
$ cd dynamic-compiler
## if you already has `mvn` in path, only use this cmd
## $ mvn compile package install
## if you doesn't has `mvn` in path, then use this cmd
$ ./mvnw compile package install

Method

Compile java source

import tech.weiyi.dynamic.bytecode.compiler.DynamicCompiler;
import tech.weiyi.dynamic.bytecode.compiler.MemoryClazzFile;


import java.util.Map;


class TestCompile {
    public void testCompile(String clazzName, String clazzSource) {
        Map<String, MemoryClazzFile> byteClazzMap = DynamicCompiler.compile(clazzName, clazzSource);
    }
}

Analysis clazz element

import tech.weiyi.dynamic.bytecode.analysis.ClazzCallAnalyzer;
import tech.weiyi.dynamic.bytecode.analysis.ClazzElement;
import tech.weiyi.dynamic.bytecode.compiler.MemoryClazzFile;

import java.util.Map;
import java.util.Set;

class TestAnalysisClazz {
    public void testAnalysisClazz(String clazzName, Map<String, MemoryClazzFile> memClsMap) {
        MemoryClazzFile memoryClazzFile = memClsMap.get(clazzName);
        Set<ClazzElement> clazzElements = ClazzCallAnalyzer.getUsedClassSet(memoryClazzFile.getBytes());
    }
}

Analysis method element

import tech.weiyi.dynamic.bytecode.analysis.MethodCallAnalyzer;
import tech.weiyi.dynamic.bytecode.analysis.MethodCallElement;
import tech.weiyi.dynamic.bytecode.compiler.MemoryClazzFile;

import java.util.Map;
import java.util.Set;

class TestAnalysisMethod {
    public void testAnalysisMethod(String clazzName, Map<String, MemoryClazzFile> memClsMap) {
        MemoryClazzFile memoryClazzFile = memClsMap.get(clazzName);
        Set<MethodCallElement> methodCallElements = MethodCallAnalyzer.getUsedClassSet(memoryClazzFile.getBytes());
    }
}
