将字符串转换为方法和参数列表

import java.lang.reflect.Method;

public class StringToMethodConverter {
    public static void main(String[] args) throws Exception {
        String className = "com.example.MyClass";
        String methodName = "myMethod";
        String[] parameterTypes = {"java.lang.String", "int"};

        // 加载类
        Class<?> clazz = Class.forName(className);

        // 获取方法
        Method method = clazz.getMethod(methodName, getClassTypes(parameterTypes));

        // 创建对象实例
        Object instance = clazz.getDeclaredConstructor().newInstance();

        // 准备参数
        Object[] arguments = {"Hello", 123};

        // 调用方法
        Object result = method.invoke(instance, arguments);

        System.out.println("Result: " + result);
    }

    private static Class<?>[] getClassTypes(String[] parameterTypes) throws ClassNotFoundException {
        Class<?>[] classTypes = new Class<?>[parameterTypes.length];
        for (int i = 0; i < parameterTypes.length; i++) {
            classTypes[i] = Class.forName(parameterTypes[i]);
        }
        return classTypes;
    }
