VSCode 定义代码模板

news 2024/9/20 20:37:25

在使用编写代码的过程中，经常会写一些固定代码段。

以 Java 为例，定义实体类时一般都会编写序列化版本号：

@Serial
private static final long serialVersionUID = 1L;

这段代码是固定写法，基本不会变，如果每次都手写的话，就比较繁琐了。

VSCode 提供了生成代码段的功能，为我们提供了便利。步骤如下：

选择代码生成配置
选择文件后缀

上方出现了各种后缀文件的选择，这里以选择 java.json 为例：

此时的 java.json 是没有实际内容的，只是以注释的方式提供了一个示例。

编写代码生成配置

这里以自用的两个代码生成为例：

java.json：

{"实现序列化接口": {"prefix": "is","body": ["implements Serializable "]},"序列号版本号": {"prefix": "ser","body": ["@Serial","private static final long serialVersionUID = 1L;"]},"单元测试方法": {"prefix": "test","body": ["@Test","public void test() {","","    $1","}"]},"Swagger控制层注解": {"prefix": "tag","body": ["@Tag(name = \"$1\")"]},"Swagger接口注解": {"prefix": "ope","body": ["@Operation(summary = \"$1\")"]},"Swagger类注解": {"prefix": "sch","body": ["@Schema(description = \"$1\")"]},"生成ArrayList": {"prefix": "list","body": ["List<$1> list = new ArrayList<>();"]},"生成HashSet": {"prefix": "set","body": ["Set<$1> set = new HashSet<>();"]},"生成HashMap": {"prefix": "map","body": ["Map<String, Object> $1 = new HashMap<>();"]},"时间": {"prefix": "pd","body": ["private Date "]},"整数": {"prefix": "pi","body": ["private Integer "]},"长整数": {"prefix": "pl","body": ["private Long "]},"当地时间": {"prefix": "pld","body": ["private LocalDateTime "]},"字符串": {"prefix": "ps","body": ["private String "]},"静态不变长整数": {"prefix": "psfl","body": ["public static final long "]},"静态不变字符串": {"prefix": "psfs","body": ["public static final String "]}
}

xml.json：

{"MyBatis模板": {"prefix": "mybatis","body": ["<?xml version=\"1.0\" encoding=\"UTF-8\"?>","<!DOCTYPE mapper PUBLIC \"-//mybatis.org//DTD Mapper 3.0//EN\" \"http://mybatis.org/dtd/mybatis-3-mapper.dtd\">","<mapper namespace=\"$1\">","    ","</mapper>"]}
}
