可以用jpa的like關鍵字查詢，比如@Query(value = "select * from search_key a where a.key_name like CONCAT('%',:keyName,'%') limit 1", nativeQuery = true)List<SearchKey> findByKeyNameLimit(@Param("keyName") String keyName);
Error creating bean with name 'helloController': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'cupSize' in string value "${cupSize}" 解決方法，把yml文件替換成下面的就o啦，server:
port: 8080
context-path: /girl
cupSize: B
age: 18
