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 ListWebSocket allSockets new ArrayList();/*** 处理消息链对象*/public ListIMessageDeal LinkListnew 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*/Overridepublic 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*/Overridepublic 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*/Overridepublic 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*/Overridepublic void onError(WebSocket conn, Exception ex) {LogUtils.WriteExceptionLog(发生错误: conn.getRemoteSocketAddress(),ex);}/*** 启动事件*/Overridepublic 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);}}
实现exe程序
package Monitor;import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.geometry.Insets;
import javafx.geometry.Orientation;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.SplitPane;
import javafx.scene.control.TextArea;
import javafx.scene.layout.HBox;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
import Monitor.Websocket.WebsocketServer;
import Monitor.Msg.MessagePrintDeal;import java.net.URL;
import java.nio.file.Paths;public class Main extends Application {// 创建一个TextArea控件TextArea textInfo new TextArea();//日志路径String logPath;Overridepublic void start(Stage primaryStage) throws Exception{String projectPath System.getProperty(user.dir);Monitor.Util.LogUtils.WriteDebugLog(项目路径 projectPath);URL url Main.class.getResource();String bashPath url.getPath();Monitor.Util.LogUtils.WriteDebugLog(程序路径:bashPath);//日志路径logPath Paths.get(projectPath,logs,Debug.log).toString();// 设置文本自动换行textInfo.setWrapText(true);Monitor.Util.LogUtils.WriteDebugLog(启动Websockt);WebsocketServer servernew WebsocketServer(8082);MessagePrintDeal printDealnew MessagePrintDeal();server.LinkList.add(printDeal);server.start();SplitPane splitPane new SplitPane();splitPane.setOrientation(Orientation.VERTICAL);// 刷新日志按钮Button btnRefresh new Button(刷新日志);btnRefresh.setOnMouseClicked(e - {RefreshLogs();});btnRefresh.setPrefHeight(30);// 清空日志按钮Button btnDelete new Button(清空日志);btnDelete.setOnMouseClicked(e - {DeleteLogs();});btnDelete.setPrefHeight(30);HBox top new HBox(20,btnRefresh,btnDelete);top.setPadding(new Insets(5,5,5,5));top.setPrefHeight(40);top.setMaxHeight(40);HBox bottom new HBox(textInfo);textInfo.prefWidthProperty().bind(bottom.widthProperty());RefreshLogs();//VBox left new VBox(new Label(left));//VBox center new VBox(new Label(center));//VBox right new VBox(new Label(right));//SplitPane splitPane1 new SplitPane();//splitPane1.getItems().setAll(left,center,right);splitPane.getItems().addAll(top, bottom);Scene scene new Scene(splitPane);//primaryStage.setScene(scene);//Parent root FXMLLoader.load(getClass().getResource(Main.fxml));//primaryStage.setTitle(JRTClient);primaryStage.setOnCloseRequest(event - {try {server.stop();}catch (Exception ex){}});primaryStage.setScene(scene);primaryStage.setMaximized(true);primaryStage.show();}/*** 刷新日志*/public void RefreshLogs(){try {textInfo.setText(Monitor.Util.TxtUtil.ReadTextStr(logPath));}catch (Exception ex){}}/*** 清空日志*/public void DeleteLogs(){try {Monitor.Util.TxtUtil.WriteText2File(logPath,);textInfo.setText();}catch (Exception ex){}}public static void main(String[] args) {launch(args);}
}
实现打印画图类
package Monitor.Print;import java.awt.*;
import java.awt.print.*;public class PrintProtocol implements Printable {/*** 按打印元素绘制协议实现打印* param rowids 数据主键* param userCode 用户* param paramList 参数* param connectString 连接串* param printFlag 打印标识* param className 调用类名* param funcName 方法名称*/public PrintProtocol(String rowids, String userCode, String paramList, String connectString, String printFlag, String className, String funcName){try {// 通俗理解就是书、文档Book book new Book();// 设置成竖打PageFormat pf new PageFormat();pf.setOrientation(PageFormat.PORTRAIT);// 通过Paper设置页面的空白边距和可打印区域。必须与实际打印纸张大小相符。Paper paper new Paper();// 设置纸张大小为 A4 大小210 mm × 297 mmdouble width 827;double height 1169;double margin 10.0;paper.setSize(width, height);paper.setImageableArea(margin, margin, width - 2 * margin, height - 2 * margin);pf.setPaper(paper);book.append(this, pf,2);// 获取打印服务对象PrinterJob job PrinterJob.getPrinterJob();// 设置打印类job.setPageable(book);job.print();} catch (PrinterException e) {e.printStackTrace();}}/*** 安逸画图* param graphics* param pageFormat* param pageIndex* return* throws PrinterException*/Overridepublic int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {// 转换成Graphics2D 拿到画笔Graphics2D g2 (Graphics2D) graphics;// 设置打印颜色为黑色g2.setColor(Color.black);//打印起点坐标double x pageFormat.getImageableX();double y pageFormat.getImageableY();if(pageIndex0) {//设置打印字体字体名称、样式和点大小字体名称可以是物理或者逻辑名称Font font new Font(宋体, Font.BOLD, 14);// 设置字体g2.setFont(font);//字体高度float heigth font.getSize2D();g2.drawString(Java打印测试, (float) 10, 10);font new Font(宋体, Font.BOLD, 12);// 设置字体g2.setFont(font);// 字体高度heigth font.getSize2D();g2.drawString(张联珠, (float) 10, 60);g2.drawString(1890075****, (float) 10, 90);g2.drawString(张联珠, 10, 120);g2.drawString(0947809, 120, 120);font new Font(宋体, Font.BOLD, 12);g2.setFont(font);heigth font.getSize2D();g2.drawString(湖南长沙, 10, 150);g2.drawString(pageIndex: pageIndex, 10, 180);return PAGE_EXISTS;}else if(pageIndex1) {//设置打印字体字体名称、样式和点大小字体名称可以是物理或者逻辑名称Font font new Font(宋体, Font.BOLD, 14);// 设置字体g2.setFont(font);//字体高度float heigth font.getSize2D();g2.drawString(Java打印测试, (float) 10, 10);font new Font(宋体, Font.BOLD, 12);// 设置字体g2.setFont(font);// 字体高度heigth font.getSize2D();g2.drawString(张联珠, (float) 10, 60);g2.drawString(18900752521, (float) 10, 90);g2.drawString(张联珠, 10, 120);g2.drawString(0947809, 120, 120);font new Font(宋体, Font.BOLD, 12);g2.setFont(font);heigth font.getSize2D();g2.drawString(湖南长沙, 10, 150);g2.drawString(第2页 , 10, 180);return PAGE_EXISTS;}else{return NO_SUCH_PAGE;}}
