Java封装动态编译

最近根据公司的业务需要通过前端页面传过来字符串的代码，并且通过动态编译然后执行，支持的类型为 JS、Java字符串、class文件 的方式，由于实现的方式都各不相同，所以进行统一封装一下

1. 代码结构

2. 实现结果测试

2.1 JS代码

@Test
    public void test_Js_compile() throws ScriptException, NoSuchMethodException, InterruptedException { 
   


        CompletableFuture.runAsync(() -> { 
   
            String str = "function bbb() { print(a); return a}; bbb()";
            Map<String, Object> map = new HashMap<>();
            map.put("a", "hello world");

            DynamicCompileWrapper<?> scriptEngine = DynamicCompileFactory.getScriptEngine(DynamicCompileType.JS);
            try { 
   
                scriptEngine.execFunction(str, map);
            } catch (DynamicCompileException e) { 
   
                e.printStackTrace();
            }
        });

        CompletableFuture.runAsync(() -> { 
   
            String str = "function bbb() { print(a); return a}; ";
            Map<String, Object> map = new HashMap<>();
            map.put("a", "hello world2");
            DynamicCompileWrapper<?> scriptEngine = DynamicCompileFactory.getScriptEngine(DynamicCompileType.JS);
            try { 
   
                scriptEngine.execFunctionForMethodName(str, "bbb", map);
            } catch (Exception e) { 
   
                e.printStackTrace();
            }
        });
        Thread.currentThread().join();
    }

2.2 Java代码

 @Test
    public void test_java_compile() throws ClassNotFoundException, InvocationTargetException, IllegalAccessException, NoSuchMethodException { 
   
        String code = "public class HelloWorld {\n" +
                      " public void add(String a) {System.out.println(a);}\n" +
                      " \n" +
                      "}";
        DynamicCompileWrapper<JavaCompile> scriptEngine = (DynamicCompileWrapper<JavaCompile>) DynamicCompileFactory.getScriptEngine(DynamicCompileType.JAVA);
        JavaCompile engine = scriptEngine.getScriptEngine(code);
        engine.runMethod("add", "hello");
    }

2.3 Java文件

@Test
    public void test_java_file() { 
   
        File file = new File("E:\\my-study-project\\practice\\src\\main\\java\\com\\zhj\\demo\\tls\\Tlsdemo.java");
        JavaCompile javaCompile = null;
        try { 
   
            FileInputStream inputStream = new FileInputStream(file);
            ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
            byte[] bytes = new byte[1024];
            int tempChar;
            while ((tempChar = inputStream.read(bytes)) != -1) { 
   
                outputStream.write(bytes, 0, tempChar);
            }
            javaCompile = createInstance().getScriptEngine(new String(outputStream.toByteArray(), StandardCharsets.UTF_8));
            javaCompile.runMainMethod(new String[]{ 
    });
        } catch (Exception e) { 
   
            e.printStackTrace();
        }
    }
