Package io.r2mo.dbe.mybatisplus.core.typehandler

Class TypedUUIDHandler

java.lang.Object

org.apache.ibatis.type.TypeReference<Object>

org.apache.ibatis.type.BaseTypeHandler<Object>

io.r2mo.dbe.mybatisplus.core.typehandler.TypedUUIDHandler

All Implemented Interfaces:

org.apache.ibatis.type.TypeHandler<Object>

@MappedJdbcTypes({VARCHAR,BINARY,OTHER})
@MappedTypes(java.util.UUID.class)
public class TypedUUIDHandler
extends org.apache.ibatis.type.BaseTypeHandler<Object>

兼容型 UUID TypeHandler： - Java 写入：支持 UUID / CharSequence(含 String) / byte[16] - DB 列：支持 VARCHAR / BINARY(16) / OTHER - 读取：返回 UUID（仅绑定到 UUID 属性上，不绑定 String）

使用建议： 1) 实体字段用 UUID：本 Handler 生效（推荐）。 2) 实体字段用 String：不要让本 Handler 绑定到 String；直接走默认 StringTypeHandler 即可。
