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);
