Eclipse调试无需中断即可执行Java程序 [英] Eclipse debug execute Java program without stopping at breakpoint

问题描述

我是Java的新手，正在尝试调试Java代码，并希望在断点处停止执行。但是我在调​​试视图中得到以下消息：

I new to Java and I'm trying to debug a Java code and expecting to stop execution at breakpoint. But I get below message in my debug view:

<terminated>pullData [Java Application] 
    <terminated>Core_java.Excelread at localhost:57966  
    <terminated, exit value: 0>C:\Program Files\Java\jdk1.8.0_144\jre\bin\javaw.exe (25-Nov-2017, 12:04:21 PM)  

以下是我的代码：

 import java.io.*;
 import jxl.*;

 public class Excelread {

     public static void main(String[] args) throws Throwable {
         String Filename = "C:\\library\\TestData.xls";
         String Sheetname = "Source";
         String[][] arrayExcelData = null;
         FileInputStream fis = new FileInputStream(Filename);
         Workbook WB = Workbook.getWorkbook(fis);
         Sheet SH = WB.getSheet(Sheetname);
●        SH.getColumns();
         SH.getRows();

             /* System.out.println(TotalCol +" "+ TotalRow);
             arrayExcelData = new String [TotalRow][TotalCol];
             for (int i=0; i<TotalRow; i++) {
                 for(int j=0;j<TotalCol;j++) {
                     arrayExcelData[i][j] = SH.getCell(j,i).getContents();
                     System.out.print(arrayExcelData[i][j]+ "\t");
                 }
                 System.out.println();
             }*/
     }
 }

推荐答案

如果设置断点并执行 Run → Run 而不是 Run → Debug （或通过相应的工具栏按钮而不是）断点将被忽略。

If you set a breakpoint and perform Run → Run instead of Run → Debug (or via the according toolbar buttons instead of ) the breakpoint is ignored.

请参见帮助-Eclipse平台，以调试模式启动Java程序。

BTW，所有大写变量名（ WB ， SH ）应用于 final 变量，即仅常量按惯例。

BTW, all uppercase variable names (WB, SH) should be used for final variables, i.e. constants only by convention.

并抛出 Throwable 通常没有多大意义，因为 错误 是 Throwable 及其说明如下：

And throwing a Throwable usually doesn't make much sense, since Error is a direct subclass of Throwable and its description reads:

错误是 Throwable 的子类，它指示严重的问题，即合理的应用程序不应尝试赶上。

An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch.
