我正在制作需要动态创建java字节码的软件,甚至可能使它成为一个可运行的jar.
我目前的想法是创建一个新的.java文件并在运行时编译它.我可以创建文件,但我不确定如何在运行时编译它,并使它成为一个可运行的jar.任何帮助将不胜感激.
public static String generate(String filePath) {
try {
File file = new File("Test.java");
if(!file.exists())file.createNewFile();
FileWriter write = new FileWriter(filePath+".java");
BufferedWriter out = new BufferedWriter(write);
out.write(
"public class Test {\n\t" +
"public static void main(String[] args){\n\t\t"+
"System.out.println(\"Working\");\n\t"+
"}\n" +
"}"
);
out.close();
} catch (Exception e) {// Catch exception if any
return "Error: " + e.getMessage();
}
return "Test.java created!";
}
