一、功能报错类异常场景

在使用系统过程中，出现以下几类异常，通常定义为功能类报错异常，可以采用本文档方案跟踪：

1.系统功能使用过程，有明确异常提醒的

1）场景一：界面弹出异常

点击【显示栈信息】或查看错误详情，可以看到详细错误日志（如报问题就是把这个复制之后报问题）：

2）场景二：启动失败，日志有ERROR日志的，也算是异常提醒

3）场景三：ETL运行失败，在具体节点右键菜单-->查看日志

2.前端个别操作界面打开空白或没反应，但又不是系统整体无响应的

二、跟踪方法

2.1系统功能使用过程，有明确异常提醒的

2.1.1理解报错详情

无论是通过界面弹窗显示的提醒，还是启动过程看到的错误日志，都有个错误详情，也就是程序里的调用栈，调用栈结构：

  • 栈顶（最上方）：最近调用的函数（最后执行的操作）。

  • 栈底（最下方）：最初调用的函数（程序的起点）。

  • 错误通常出现在栈顶附近，但根源可能在栈底方向。

栈中每个函数都会显示函数名、所在源码文件或包、源码文件行号，这些可有助于程序员定位程序异常，对于系统使用者主要关注错误描述。

调用栈伪代码
Exception in thread "main" java.lang.ArithmeticException: Division by zero 
	at com.Example.calculateTotal(Example.java:15)  
	at com.Example.processOrder(Example.java:5)  
	at com.Example.main(Example.java:20)

上例调用路径：main() → processOrder() → calculateTotal()，错误发生在calculateTotal中。

相当于如果函数A调用函数B，函数B调用函数C，而错误发生在函数C中，调用栈会显示C → B → A， 如果错误发生在C，但是B也封装了一个新异常抛出，相当于B也发生异常，就会出现两个错误调用栈：B→ A Caused by: C→ B→ A，而后一个C→ B→ A藏着真正的异常原因。

上例在processOrder捕捉calculateTotal的异常，封装为“计算订单总价失败”，错误详情就是类似如下：

调用栈伪代码
Exception in thread "main" java.lang.RuntimeException: 计算订单总价失败
	at com.Example.processOrder(Example.java:5)  
	at com.Example.main(Example.java:20)  
Caused by: java.lang.ArithmeticException: Division by zero 
	at com.Example.calculateTotal(Example.java:15)  
	at com.Example.processOrder(Example.java:8)  
	... 2 more


这类异常跟踪口诀就是“从下往上看，Caused by 是根源；从上往下读，业务封装是表象。”

2.1.2跟踪排查步骤

1.聚焦错误描述：找到最后一个 Caused by，没Caused by的直接是调用栈顶部的错误信息：

上例它指向最原始的错误（如 Division by zero）。

2.提炼错误关键字搜索，忽略变量名或具体的值

如上述案例的错误关键字就可以提炼为：

错误描述：Division by zero（除数为0）

错误类型：java.lang.RuntimeException

还有以下一个smartbi中的真实案例：

提炼的内容有：

错误描述：获取数据库连接失败，Unknown server host name

错误类型：java.sql.SQLException

上例'10.110.111.2251'，属于具体值，变量值通常在搜索中无用的，不同系统会不同。

3.利用互联网资源搜索解决方案

1）直接在搜索引擎中搜索刚刚提炼的错误关键字

“获取数据库连接失败，Unknown server host name ”，如不知如何解决无法识别主机地址的异常，可互联网或AI搜索：



2）利用AI搜索

以下是AI搜索的效果（借助AI搜索，不提炼关键字，整个错误堆栈复制进去也可）：

2.1.3上报问题

当出现明确异常提醒的情况，在借助互联网资源、官方WIKI文档、社区、或问题跟踪系统等搜索无法找到解决方案，需按以下方式上报异常：

在使用系统什么功能（复杂的需描述操作复现步骤），出现什么异常，异常详细信息，其中异常详细信息就是错误弹窗中【显示栈信息】/错误详情，点进去可复制，里面含有版本号和详细的错误栈。

以下面这个系统功能异常为例：

错误描述：在把数据库添加到Smartbi，测试数据连接过程，出现连接报错

操作步骤：新建数据连接--->测试连接

如不方便复制详情，也可通过拍照等手段，关键需要参照前面跟踪排查手段，把关键错误信息要上报发回（通常是错误详情的开始一页，以及最后一个Caused by:部分及上下文）。

上报途径可参照系统功能导航页：

2.2.2前端个别操作界面打开空白或点击没反应，但又不是系统整体无响应的

这类异常通常是浏览器端出现脚本异常，或服务端返回不合前端预期带来的前端异常，通常此时可通过浏览器开发者工具查看是否有脚本异常，把此脚本异常上报发回。

每个浏览器的开发者工具打开可能有所不同，可互联网搜索“浏览器名 开发者工具打开方式”，如chrome，就是右上角工具-->更多工具-->开发者工具，切换到控制台看脚本异常。

上报问题除了这个错误截图，需描述重现操作步骤。

三、常见问题

1.上报问题时仅截取错误弹窗，未附上重现步骤、错误详情

错误弹窗内的错误描述经常是不全的，或其并非根因，需要看错误详情中的底部Caused by，如未附上错误详情，通常开发人员无法定位问题。

面对系统的一些未知异常，如报“系统检查错误”，虽有错误详情及代码位置，但依然需要借助重现才能解决问题，所以能重现的问题，上报时告知重现步骤可提高解决效率。

2.互联网搜索解决方案时，未提炼错误描述，把变量名具体值带入搜索

功能类的异常提醒，需大概理解错误描述内容，提炼里面的错误描述及业务关键字，因为带入太多无意义信息，可能让搜索效果大打折扣。如在百度搜索：“获取数据库连接失败[cause Throwable ClassName:java.sql.SQLException]:获取数据库连接失败[cause Throwable ClassName:java.sql.SQLException]:Unknown server host name '11.10.111.2251'.,datasourceId=I8a8aedaa019564656465cd6c01956f4ef6555ce6”，效果会远不如：“获取数据库连接失败，Unknown server host name”。

如果是借助AI搜索，因其本身会理解用户意图，这个问题可忽略。

3.忽略借助AI搜索，提升问题解决效率

很多AI，如DeepSeek、豆包，不仅可以输入文字搜索，也可粘帖图片，接收图片搜索，在不知道错误描述在说什么不知如何提炼关键词时，可借助AI搜索原因及解决方案。
