反射 与文件读写 泛型参数

最近公司项目需要根据bean生成对应的yaml配置文件,需要用到反射和文件操作,API总结如下:

文件读写:

        File file = new File(path);
        file.isDirectory();
        File[] files = file.listFiles();

                String name = file1.getAbsolutePath();
                name = file1.getName();


        File file = new File(path + c.getSimpleName() + ".yaml");
        if (file.exists()) {
            file.delete();
        }
        file.createNewFile();
        FileWriter fileWriter = new FileWriter(file);
        BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);

        bufferedWriter.write("definitions:");
        bufferedWriter.newLine();

        bufferedWriter.flush();
        bufferedWriter.close();

反射:

Class c =  Class.forName("model." + name);
Field[] fields = c.getDeclaredFields();
Class c = field.getType();
field.getType().getSimpleName()
//泛型参数
        Type fieldType = field.getGenericType();
        //获取对应的泛型类
        Type type = ((ParameterizedType) fieldType).getActualTypeArguments()[0];
        String name = type.getTypeName();
