1、打开首选项配置
2、选择全局的

3、填写自己的代码块

{// Place your 全局 snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and // description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope // is left empty or omitted, the snippet gets applied to all languages. The prefix is what is // used to trigger the snippet and the body will be expanded and inserted. Possible variables are: // $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. // Placeholders with the same ids are connected.// Example:"Print to console": {// 作用文件类型。就是代码块的作用文件类型"scope": "java",// 触发代码块的字符串。写代码的时候我们只需敲出这个字符串就会触发我们的代码块。"prefix": "std",// \$1使用代码块敲击回车或者tab键后光标定位的位置。 $2 $3 $4...表示我们按下tab光标依次出现的位置"body": ["System.out.println(\"$1\");","$2"],"description": "print"}
