logback 显示带有行号的日志

Question

I want to write log like:

2014-04-17 11:00:16.408 [http-apr-9090-exec-4] DEBUG package.method(line) - log.

so I config the logback.xml, in the pattern, the config like:

%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36}.%M(%line) - %msg%n

Every thing shows ok except the line number, and if i add set like

%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36}.%M %line - %msg%n

Then all works. so there must be something wrong with my configuration.
Could anyone help me ? Thanks. I want to display like what I want, and no space between method name and line number.

The Logback manual states

In PatternLayout, parenthesis can be used to group conversion patterns. It follows that the '(' and ')' carry special meaning and need to be escaped if intended to be used as literals. The special nature of parenthesis is further explained below.

[...]

If you need to treat the parenthesis character as a literal, it needs to be escaped by preceding each parenthesis with a backslash. As in, \\(%d{HH:mm:ss.SSS} [%thread]\\) .

You'll need to escape the parenthesis with a \\ .

%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36}.%M\(%line\) - %msg%n

任何偶然发现此页面以寻找如何在 application.properties 文件中配置它的人的说明，我通过添加两个反斜杠成功地转义了括号。

%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36}.%M \\(%line\\) - %msg%n

For console logging I use:

<Pattern>%black(%date{"yyyy-MM-dd HH:mm:ss.SSS", "Europe/London"}) %highlight(%-5level) [%green(%X{sessionId})] %yellow(%logger{36}@%method\(%line\)) - %msg%n%throwable</Pattern>

And for logging to file:

 <pattern>[%date{"yyyy-MM-dd HH:mm:ss,SSSXXX", "Europe/London"}] [${HOSTNAME}] [%thread] %level %logger{36}@%method:%line - %msg%n</pattern>

If you want to have log messages where you can click on a link into the source code, eg in IntelliJ, use the following pattern for console logging inside your IDE:

<pattern>
    %d{dd-MM-yyyy HH:mm:ss.SSS} %highlight(%-5level) %magenta([%thread]) %yellow(%logger{40}.%M\(%class{0}.java:%line\)) - %msg%throwable%n
</pattern>
