网络框架:java_chainMarket

  • 由本人独立开发对通讯底层NETTY4进行二次封装的轻量级网络框架
  • 为集成本人所有开源技术包的轻量级网络框架

网络框架有很多稳定且功能全面的重量级框架比如ssm,boot之类的,为什要做这个?

  • 底层是NETTY4,所以很稳定,我只是给NETTY做二次封装了,所以不要怕这种轻量级的网络框架有风险之类的问题
  • 第一目的:降低入门门槛。因为轻量级,超级傻瓜化,有点javaSE基础的人应该十分钟就能上手。
  • 第二目的:自由度高。比如可以随意定义返回的HTTP状态码,起码对于我这种老鸟来说,随意定义很舒服
  • 第三目的:我可以持续集成,不断的集成我其他开源技术包的融合进来,比如集成我的ImageMarket机器视觉包 ,又比如之后要集成的自然语言包TalkMarket(对用户语言做分类识别,实现纯语言交互类似苹果siri)
  • 第四目的:让我的其他技术包集成进来之后,一包导入就可使用我所有人工智能或者其他开源技术服务

关于持续集成技术包

  • 目前正在更新的开源项目是 ImageMarket,机器视觉包,也将会集成进chainMarket。 地址:https://gitee.com/ldp_dpsmax/easyAi
  • 准备增加的还有一个JAVA热更新组件,原理就是自己开发了一套脚本解释器,用户使用脚本写业务逻辑, 通过我的解释器运行,因为是解释器运行,所以修改脚本就可实现动态热更业务逻辑代码。
  • 还要增加一个自然语言处理包,类似siri,对用户说话的语义进行只能分类分析提供交互,比如用户说"我渴了" ,我会给用户推喝水的信息,前端就会产生响应的反应。

此轻量级框架必须依赖NETTY4

  • io.netty netty-all 4.1.13.Final compile
  • 因为是对NETTY做封装,所以肯定要依赖NETTY。
  • 我提供的这个NETTY4版本有些老了,所以NETTY大版本只要是NETTY4,你可以在POM文件里随意换一个 NETTY版本,不会对框架产生影响。

HTTP服务

public class App {
    public static void main(String[] args) {
        init();
        //初始化chainMarket服务
        HttpServer httpServer = new HttpServer();
        //参数分别是 端口号
        //control类所在的包路径(接口入口类所在的包路径),
        // 允许接收的最大字节数(超过这个数量,将直接返回400错误码)
        //websocket url,
        //websocket 回调类
        //启动chainMarket服务
        httpServer.start(8080, "com.shareData.chainMarket.test", 1024,
                null, null);
        //若要启动WEBSOCKET服务,请将后两个参数传入
       //httpServer.start(8080, "com.shareData.chainMarket.test", 1024,
       //"ws://127.0.0.1:8080/websocket", new MyWebSocket());
    }

    public static void init() {
        //是否启动SSL服务,若启动则服务器无法接收HTTP请求,只能接收HTTPS请求
        //反之也一样
        HttpsSetting.sslEnabled = false;//不启动SSL服务,不设置就是默认不启动
        HttpsSetting.keystorePath = "SSL证书在磁盘上的地址";
        HttpsSetting.certificatePassword = "SSL证书密码";
        HttpsSetting.keystorePassword = "SSL证书密码";//上下两者等同
        Config.setFileMaxLength(6553666);//上传文件的最大大小,单位BIT
    }

}
//在设置的control包路径下,创建control类
//注解 Central代表虚拟路径名称,在内部的URL中填写虚拟路径
//这样这两个接口地址分别是 /login/wxLogin,/login/getCommunity
//不区分post,get,message是 POST体的参数,map 是url?后面的健值对(get参数)
//return 是返回内容
@Central(url = "/login")
public class Login {
@Central(url = "/wxLogin")
public String wxLogin(String message, Map<Object, Object> map) {//微信小程序登录
    return wxLogin(message);
}

@Central(url = "/getCommunity")
public String land(String message, Map<Object, Object> map) {//获取全部社区
    return getSmallCity();
}
//若是FORM表单提交信息,请使用List<FileAndName> forms 来接收
@Central(url = "/list")
    public String list(List<FileAndName> forms) {
        return "a";
        }
}
//List<FileAndName>
//FileAndName 是一个健值对,LIST就是接收的一个健值对集合
//FileAndName 中有三个参数
//name,键名
//text,文本类型的值
//inputStream,二进制文件类型的值
//注意文本类型和二进制类型互斥,有其中一种,另一种就是null。
//从inputStream中读取字节码后,无需关闭字节流,return之后底层会自动关闭
    public class FileAndName {
        private InputStream inputStream;
        private String name;
        private String text;
    }

WEBSOCKET 服务

        public class MyWebSocket extends WebSocketBack {
        //若启用WEBSOCKET,创建回调类
        //且必须继承WebSocketBack,并重写active方法和 getText方法
        @Override
        public void active(ChannelHandlerContext ctx) {
        //当用户进行WEBSOCKET握手时激活,一个用户构成一个连接有且只执行一次
            System.out.println("激活了======");
        }
    
        @Override
        public String getText(String message, ChannelHandlerContext ctx) {
          //收到一个WEBSOCKET通讯
          //将一个通讯的信道注册起来,与主键绑定
          WebSocketManager.register(1,ctx);
          //通过绑定的主键,服务端主动给用户PUSH信息
          WebSocketManager.putMessage(1,"发送信息");
    
            return "ok";
        }}
