1. 生成类注释

打开Preferences-->Editor-->File and Code Templates，右侧选择Filestab页，找到Class、Interface，可以看到右侧模板里引用了一个File Header.java模板，如下图：

模板变量说明

${PACKAGE_NAME} name of the package in which the new file is created

${USER} current user system login name

${DATE} current system date

${TIME} current system time

${YEAR} current year

${MONTH} current month

${MONTH_NAME_SHORT} first 3 letters of the current month name. Example: Jan, Feb, etc.

${MONTH_NAME_FULL} full name of the current month. Example: January, February, etc.

${DAY} current day of the month

${DAY_NAME_SHORT} first 3 letters of the current day name. Example: Mon, Tue, etc.

${DAY_NAME_FULL} full name of the current day. Example: Monday, Tuesday, etc.

${HOUR} current hour

${MINUTE} current minute

${PROJECT_NAME} the name of the current project

建立类自动生成类注释，如下图所示

2. 生成方法注释

打开Preferences-->Editor-->Live Templates，为了方便管理，新建一个分组来管理自己添加的Live Template，名为myGroup,

复制粘贴以下的模板

**

* @Author:

* @Description:

* @Date: $date$ $time$

$params$

$return$

**/

设置变量

params变量，放在Default value中

groovyScript("if(\"${_1}\".length() == 2) {return ‘‘;} else {def result=‘‘; def params=\"${_1}\".replaceAll(‘[\\\\[|\\\\]|\\\\s]‘, ‘‘).split(‘,‘).toList();for(i = 0; i < params.size(); i++) {if(i==0){result+=‘* @Param ‘ + params[i] + ‘: ‘}else{result+=‘\\n‘ + ‘ * @Param ‘ + params[i] + ‘: ‘}}; return result;}", methodParameters());

return变量，放在Default value中

groovyScript("def returnType = \"${_1}\"; def result = ‘* @return: ‘ + returnType; return result;", methodReturnType());

设置快捷键

设置范围为java

使用说明

需要自己打出来/*，然后按回车生成方法注释。
