Can't restore sql from selection about mybatis-log-plugin

[ooooo84]

如果将设置改为STDOUT_LOGGING就没有问题

[kookob]

@ooooo84 方便的话，帮忙贴个文本串出来，可能不同的输出方式，存在一些特殊格式。

@ooooo84 你这个是LOG4J2的吗？我验证是可以解析正常的，无法复现，你那边是每次都报：
”Can't restore sql from selection.“ 这个吗？多验证几次看看。

[ooooo84]

我知道是什么原因了，出问题的log4j2的配置为：
<PatternLayout pattern="%m %n"/>
把空格去了，改成
<PatternLayout pattern="%m%n"/>
就正常了

[kookob]

@ooooo84 嗯，是这个问题，这个问题很有代表性，很多插件不起作用可能是这个原因引起的。
解释一下：
主要是第二行的参数解析，在N多用户跑的各种项目的过程中，参数格式多种多样，比如富文本的，字符串包含换行的，包含(String), (Long), null 关键字等等等等。
要统一正确解析要涉及到各种格式判断，所以参数行如果以空格结束，会判断不出是已经结束还是换行的参数。
所以 %msg%n 这个配置大家要注意，不能带有空格，而且正确的配置也不应该带空格。

环境是：springboot 2.x and mybatis-log-plugin 2.0.7 and logback
选中sql，然后右键“Restore Sql from Selection”,会出“Can't restore sql from selection”,但是项目重启后，刚才选中的sql，就能输出出来。
