IntelliJ IDEA

• IDEA 默认会自动保存修改,坏处是可能会因为无意识触碰键盘引起的修改，导致莫名的 bug

• 设置默认 Maven 配置

旧版	File -> Other Settings -> Settings for New Projects
新版	File -> New Projects Setup -> Settings for New Projects...

• 快捷键 {| class="wikitable" |+ | colspan="2" |Ctrl+Alt+L | colspan="2" |格式化代码 |- | colspan="2" |Ctrl + D | colspan="2" |删除当前一行 |- | colspan="2" |sout+Enter | colspan="2" |System.out.println |- | | | | |}

设置代码行宽,并自动到达行宽后自动换行
