java中怎么配置类的注释_Java-idea-设置类头注释和⽅法注释⼀、⽂件级别的注释
主要是通过File--》Setting--》Editor→File and Code Template中来设置
可以再右侧include中设置File Header
可设置值：
Predefined variables will take the following values:
${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
个⼈⼀般设置成
/*** @className ${NAME}
* @description TODO
*@author${USER}
*@since${DATE} ${TIME}
*@version1.0*/
⼆、⽅法级别的注释
基于Live Template
基础的Live Template
psvm+tab，main⽅法
iter+tab，foreach语句
live template还有⼀个surround的⽤法，选中某个变量，键⼊ctl+alt+j两次，则会出现⾃动补全的菜单
基本步骤
1、点击File--》Setting--》Editor→Live Template，点击右侧的+号，选择Template Group
2、输⼊MyGroup(你也可以输⼊其他⾃定义的名称)，然后点击OK。
3、选中MyGroup之后，再次点击右侧的+号，选择Live Template，
其中Abbreviation 必须是* ，使⽤过程中可以输⼊ /**  回车即可
java中split的用法
模板
*
*@description TODO*@author $user$*@since $date$ $time$
$param$* @return $return$*/
4、点击第四步的Define，选择EveryWhere 选择java即可
5、点击右边的Edit variables
其中 $param$ 的表达式值
groovyScript("def result=''; def params=\"${_1}\".replaceAll('[\\\\[|\\\\]|\\\\s]', '').split(',').toList(); for(i = 0; i < params.size(); i++) {result+=' * @param ' + params[i] + ((i < params.size() - 1) ? '\\n' : '')}; return result", methodParameters())
其他的按照实际下拉选择即可
6、点击OK，⽅法上输⼊ /**  回车即可
