JRT和检验共用的打印层实现

之前对接的打印和导出是C#实现的，如果要完全Java化就需要用Java把打印元素绘制协议用Java实现，这次介绍实现主体搭建，最终使JRT达到完全信创和跨平台目标。到这篇后，所有的Java难题都解决完毕，几天到几周之内就可以把打印元素绘制协议完全实现，实现看着很快。至此可以一马平川的用Java了，没有M，一样可以领先，哈哈哈哈，框架完全体快出来了。

首先抽取消息处理接口

package Monitor.Msg;

import org.java_websocket.WebSocket;

/**
 * 抽取的处理前端传来的消息接口，不同类型的消息处理实现此接口从而实现不同的功能
 */
public interface IMessageDeal {
    /**
     * 处理消息
     * @param socket 套接字，可以获得id，发送消息给socket
     * @param message 约定#分割的第一位描述消息类型，收到的消息内容
     * @return 是否继续往后传递消息，true是，false否
     */
    public boolean DealMessage(WebSocket socket, String message);
}

然后实现打印消息处理

package Monitor.Msg;
import Monitor.Util.LogUtils;
import javafx.scene.control.Alert;
import org.java_websocket.WebSocket;

/**
 * 处理打印消息
 */
public class MessagePrintDeal implements Monitor.Msg.IMessageDeal {
    /**
     * 处理消息
     * @param socket 套接字，可以获得id，发送消息给socket
     * @param message 约定#分割的第一位描述消息类型，收到的消息内容
     * @return 是否继续往后传递消息，true是，false否
     */
    public boolean DealMessage(WebSocket socket, String message)
    {
        LogUtils.WriteDebugLog("识别以print#开头的消息");
        //识别打印消息
        if (message.split("#")[0].equals("print"))
        {
            LogUtils.WriteDebugLog("确定为打印消息，准备处理");
            int index = message.indexOf('#');
            String msg = message.substring(index + 1);
            String[] arrMsg = msg.split("@");

            //报告打印消息直接处理，不驱动exe，提高速度
            if (arrMsg.length > 5 && (!arrMsg[4].contains("PDF#")) && (arrMsg[0].equals("iMedicalLIS://0") || arrMsg[0].equals("iMedicalLIS://1")) && (!arrMsg[4].equals("ReportView")))
            {
                String cmdLine = msg.substring(14);
                String[] tmpStrings = cmdLine.split((char)64+"");
                String printFlag = tmpStrings[0];
                String connectString = tmpStrings[1].replace("&", "&amp;");
                String rowids = tmpStrings[2];
                String userCode = tmpStrings[3];
                //PrintOut:打印  PrintPreview打印预览
                String printType = tmpStrings[4];
                //参数模块名称(LIS工作站,DOC医生,SELF自助,OTH其它)
                String paramList = tmpStrings[5];

                String clsName = "";
                String funName = "";
                if (tmpStrings.length >= 8)
                {
                    clsName = tmpStrings[6];
                    funName = tmpStrings[7];
                }

                //没传报告主键退出
                if (rowids == "" && printType != "ReportView")
                {
                    javafx.application.Platform.runLater(()->{

                        Alert alert = new Alert(Alert.AlertType.INFORMATION);
                        alert.setTitle("提示");
                        alert.setHeaderText("打印参数异常");
                        alert.setContentText("未传入报告主键");
                        alert.showAndWait();
                    });
                    return true;
                };
                String ip = "";
                String hostName = "";
                String mac = "";
                paramList = paramList + "^HN" + hostName + "^IP" + ip + "^MAC" + mac;
                //printFlag  0:打印所有报告 1:循环打印每一份报告
                if (printFlag.substring(0, 1).equals("0"))
                {
                    Monitor.Print.PrintProtocol reportPrint = new Monitor.Print.PrintProtocol(rowids, userCode, paramList, connectString, printType, clsName, funName);
                }
                else
                {
                    String[] tmpRowids = rowids.split((char)94+"");
                    for (int i = 0; i < tmpRowids.length; i++)
                    {
                        rowids = tmpRowids[i];
                        if (rowids != "")
                        {
                            Monitor.Print.PrintProtocol reportPrint = new Monitor.Print.PrintProtocol(rowids, userCode, paramList, connectString, printType, clsName, funName);
                        }
                    }
                }
            }
            return false;
        }
        LogUtils.WriteDebugLog("不是打印消息，传递消息链");
        return true;
    }
}

然后实现Websockt对接消息、

package Monitor.Websocket;

import Monitor.Util.LogUtils;
import org.java_websocket.WebSocket;
import org.java_websocket.handshake.ClientHandshake;
import org.java_websocket.server.WebSocketServer;
import Monitor.Msg.IMessageDeal;

import java.net.InetSocketAddress;
import java.util.ArrayList;
import java.util.List;

public class WebsocketServer extends WebSocketServer {
    /**
     * 存所有套接字
     */
    private static List<WebSocket> allSockets = new ArrayList<>();

    /**
     * 处理消息链对象
     */
    public List<IMessageDeal> LinkList=new ArrayList<>();

    /**
     * 构造函数
     * @param port
     */
    public WebsocketServer(int port) {
        super(new InetSocketAddress(port));
        Monitor.Util.LogUtils.WriteDebugLog("启动Websockt在"+port);
    }

    /**
     * 打开链接
     * @param conn 连接
     * @param handshake 握手
     */
    @Override
    public void onOpen(WebSocket conn, ClientHandshake handshake) {
        LogUtils.WriteDebugLog("新客户端接入:" + conn.getRemoteSocketAddress());
        allSockets.add(conn);
    }

    /**
     * 断开连接
     * @param conn 连接
     * @param code 代码
     * @param reason 原因
     * @param remote 是否远程
     */
    @Override
    public void onClose(WebSocket conn, int code, String reason, boolean remote) {
        LogUtils.WriteDebugLog("客户端断开:" + conn.getRemoteSocketAddress());
        allSockets.remove(conn);
    }

    /**
     * 收到消息
     * @param conn 连接
     * @param message 消息
     */
    @Override
    public void onMessage(WebSocket conn, String message) {
        System.out.println("收到消息:" + conn.getRemoteSocketAddress() + ": " + message);
        LogUtils.WriteDebugLog("#WS消息服务准备调用消息链...");
        try
        {
            if (LinkList.size() > 0)
            {
                for(IMessageDeal deal:LinkList)
                {
                    LogUtils.WriteDebugLog("#WS调用：" + deal.getClass().getName() + "...");
                    boolean ret = deal.DealMessage(conn, message);
                    LogUtils.WriteDebugLog("#WS调用：" + deal.getClass().getName() + "结束...");
                    //返回false不传递消息了
                    if (ret == false)
                    {
                        LogUtils.WriteDebugLog("#WS消息链不继续传递消息...");
                        break;
                    }
                }
            }
            LogUtils.WriteDebugLog("#WS消息服务调用消息链结束...");
        }
        catch (Exception ex)
        {
            LogUtils.WriteExceptionLog("#WS消息服务调用消息链异常", ex);
        }
    }

    /**
     * 发生错误
     * @param conn 连接
     * @param ex 异常
     */
    @Override
    public void onError(WebSocket conn, Exception ex) {
        LogUtils.WriteExceptionLog("发生错误:" + conn.getRemoteSocketAddress(),ex);
    }

    /**
     * 启动事件
     */
    @Override
    public void onStart() {

    }

}

包装log4j

package Monitor.Util;


import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class LogUtils {

    //调试日志
    static final Logger loggerDebug = LoggerFactory.getLogger("Debug");


    /**
     * 书写调试日志
     * @param message 日志内容
     */
    public static void WriteDebugLog(String message)
    {
        loggerDebug.error(message);
    }

    /**
     * 书写异常日志
     * @param message 描述
     * @param exception 异常
     */
    public static void WriteExceptionLog(String message, Exception exception)
    {
        loggerDebug.error(message, exception);
    }

}

            catch (Exception ex)
            {

            }
        });
        primaryStage.setScene(scene);
        primaryStage.setMaximized(true);
