Thymeleaf+spring jpa+springmvc实现的增删改查以及分页查询

public interface ZxwxKFJSDWRepository extends JpaRepository<ZxwxKFJSDW, String>,
PagingAndSortingRepository<ZxwxKFJSDW, String>{
//插入数据
public ZxwxKFJSDW save(ZxwxKFJSDW jsdw);
//更新数据
public ZxwxKFJSDW saveAndFlush(ZxwxKFJSDW jsdw);
//删除数据
@Modifying(clearAutomatically = true)
public void delete(String dwm);
//按照名字来查询
public ZxwxKFJSDW findByDwm(String dwm);
/**
* 注意：在做分页查询的时候，不需要在这个借口定义方法了。可以直接调用
*/

//public List<ZxwxKFJSDW> findAll();
}

@RequestMapping(value="/kfjsdwlisthtml")
public ModelAndView jsdwdlist(@RequestParam(value="pageNumberstr",required=false)

pageNumberstr="0";
}
int pageNumber = Integer.parseInt(pageNumberstr);
