介绍: 为什么好的提交信息如此重要

当你随意浏览任一 git 仓库的日志，你很可能会发现其中的提交信息或多或少有点乱。举个例子，瞧一瞧我早先提交到 Spring 上的这些宝贝：

$ git log –oneline -5 –author cbeams –before “Fri Mar 26 2009”

e5f4b49 Re-adding ConfigurationPostProcessorTests after its brief removal in r814. @Ignore-ing the testCglibClassesAreLoadedJustInTimeForEnhancement() method as it turns out this was one of the culprits in the recent build breakage. The classloader hacking causes subtle downstream effects, breaking unrelated tests. The test method is still useful, but should only be run on a manual basis to ensure CGLIB is not prematurely classloaded, and should not be run as part of the automated build.

2db0f12 fixed two build-breaking issues: + reverted ClassMetadataReadingVisitor to revision 794 + eliminated ConfigurationPostProcessorTests until further investigation determines why it causes downstream tests to fail (such as the seemingly unrelated ClassPathXmlApplicationContextTests)
