html java 设置 style,使用html / css设置异常堆栈跟踪样式的Java库(Java library to style exception stacktrace with html...-优快云博客

使用html / css设置异常堆栈跟踪样式的Java库(Java library to style exception stacktrace with html / css)

我将异常的主体转换为字符串，然后将该异常通过电子邮件发送到java中的给定地址。我想用html格式化异常字符串，使其成为人类可读的格式，类似于它在堆栈溢出时的显示方式。我想知道Java中是否有任何库可以执行此操作？

StringWriter stringWriter = new StringWriter();

PrintWriter printWriter = new PrintWriter(stringWriter);

t.printStackTrace(printWriter);

String body = stringWriter.toString();

//add html to body here

setMessageBody(body);

为了详细说明，我的意思是将行与行分开，用不同颜色的字体显示类名，使用不同颜色的字体显示行号。这可以用一些正则表达式来完成，但是我想知道是否有一个库可以直接使用。

I am converting the body of my exception to a string, and then emailing that exception to a given address in java. I want to format my exception string with html to make it a human readable format, similar to how it is displayed on stack overflow. I was wondering if there are any libraries in Java which do this?

StringWriter stringWriter = new StringWriter();

PrintWriter printWriter = new PrintWriter(stringWriter);

t.printStackTrace(printWriter);

String body = stringWriter.toString();

//add html to body here

setMessageBody(body);

To elabarate, I mean things like separate the line with
, display class name names with a different coloured font, display line numbers with a different coloured font. This can be done with some regular expressions but I was wondering if there is a library that does it out of the box.

是的，有一对夫妇，他们甚至带有一个“免费”邮件后端：使用像slf4j或log4j这样的Java日志记录框架。

所有这些框架都可以生成带有一些配置的HTML电子邮件。一般的方法是这样的：

为所有异常创建记录器或每个类创建一个记录器。前者更容易配置，后者给你更多的自由

在此记录器中添加一个appender，配置为发送电子邮件

如果你不想在你的应用中使用日志记录，你可以编写你自己的appender来重用现有的格式化器。

Yes, there are a couple and they even come with a "free" mail backend: Use a Java logging framework like slf4j or log4j.

All these frameworks can produce HTML emails with a bit of configuration. The general approach is like this:

Create a logger for all exceptions or one logger per class. The former is easier to configure, the latter gives you more freedom

add an appender to this logger which is configured to send emails
