报错原因:sql写错了 参数加了单引号

@Select("select * from xxx.xxx_category where name like '#{name}%' order by id asc limit 1")
CategoryEntity findByName(@Param("name") String name);

正确的写法

@Select("select * from xxx.xxx_category where name like CONCAT('',#{name},'%') order by id asc limit 1")
CategoryEntity findByName(@Param("name") String name);
