springMVC-SSM项目的基本功能
1 环境搭建
2 显示所有书籍
2.1 编写主页 index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>$Title$</title>
<style>
a{
text-decoration: none;
color: #000;
font-size: 18px;
}
h3{
width: 180px;
height: 38px;
margin: 100px auto;
text-align: center;
line-height: 38px;
background: deepskyblue;
border-radius: 10px;
}
</style>
</head>
<body>
<h3>
<a href="${pageContext.request.contextPath}/book/allBook">进入书籍页面</a>
</h3>
</body>
</html>2.2 在控制层新建一个类BookController并添加查询全部书籍的方法
package com.lv.controller;
import com.lv.pojo.Books;
import com.lv.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.List;
@Controller
@RequestMapping("/book")
public class BookController {
//controller层调service层
@Autowired
@Qualifier("BookServiceImpl")
private BookService bookService;
@RequestMapping("/allBook")
//查询全部的书籍,并且返回到一个书籍展示页面
public String list(Model model){
List<Books> list = bookService.queryAllBook();
model.addAttribute("list",list);
return "allBook";
}
}2.3 编写一个展示书籍列表的页面 allBook.jsp

</form>
</div>
</div>
<div class="row chearfix">
<div class="row clearfix">
<table class="table table-hover table-striped">
<thead>
<tr>
<th>书籍编号</th>
<th>书籍名称</th>
<th>书籍数量</th>
<th>书籍详情</th>
<th>操作</th>
</tr>
</thead>
<%--书籍从数据库中查询出来,从这个list中遍历出来:foreach--%>
<tbody>
<c:forEach var="book" items="${list}">
<tr>
