JPA动态SQL

在类的头上打上 @DynamicInsert
@DynamicUpdate

即可自动动态更新

 @Test
    void updateOne() {
    
    
        // apiInfoDemoRepository.
        apiInfoDemoRepository
                .save(
                        new ApiInfoDemo().setId(5L)
                                .setTitle("fuckkkk")
                                .setMarkdownInfo("hwllorld  world")
                        .setTitle("xxooxx")
                );
        // apiInfoDemoRepository.equals()
        System.out.println(apiInfoDemoRepository.findById(5L));
    }

query 查询的写法

 @Query(value = "select a from ApiInfoDemo a where  a.title like :#{#title==null|| #title.isEmpty()?'%': '%'+#title+'%'} ")
   List<ApiInfoDemo> queryTitleLike(@Param("title") String title, Pageable pageable);
