}我们添加一个根据书籍名字查找书籍的功能
// 模糊查询
public List<books> selectBook(@Param("name") String name); <select id="selectBook" parameterType="String" resultType="books">
select * from ssmbuild.books
where bookName like CONCAT ('%',#{name},'%')
-- 采用模糊查询
</select>bookService
// 模糊查询
public List<books> selectBook(@Param("name") String name);bookServiceImpl
public List<books> selectBook(String name) {
return bookMapper.selectBook(name);
} @PostMapping("/select")
public String selectBook(String bookName,Model model){
List<books> books = bookService.selectBook(bookName);
if(books.size()==0){//如果没找到就返回错误信息并展示所有的书籍
books = bookService.queryAllBooks();
model.addAttribute("error","未查到！");
}
model.addAttribute("books",books);
return "allBook";
}这两个div都写在row的div里面，与新增在同一行
