初学b/s编程，花费了许多时间，进度颇慢！ 不过终于完成了一个简单的例子:
jsp代码
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%--@elvariable id="books" type="java.util.List<com.lzf.mt.Books>"--%>
<%--@elvariable id="book" type="com.lzf.mt.Books"--%>
<html>
<head>
<H2>This is a test SCRIPT!</H2>
<script type="text/javascript" src="/file/js/jquery-3.3.1.js"></script>
<script type="text/javascript">
$(document).ready(
function(){
$("button#btn1").click(
function(){
if ($("h2").is(":hidden")){
$("h2").show();
}
else{
$("h2").hide();
}
}
);
});
</script>
</head>
<body>
<h2>您好！</h2>
<c:choose>
<c:when test="${fn:length(books) == 0}">
<i>没有书本</i>
</c:when>
<c:otherwise>
<c:forEach items="${books}" var="book">
ID: ${book.id}:
<a href="<c:url value="/books/viewone/${book.id}" />"><c:out value="${book.title}"/></a><br />
<a href="javascript:void(0)" class="none" onmousemove="getsingleBook(${book.id})"><c:out value="${book.title}"/></a>
<br />
</c:forEach>
</c:otherwise>
</c:choose>
<h2>当前查看的书本:${book.title}</h2>

} </script> </body>

public ModelAndView listallBooks(Map<String, Object> model){
ModelAndView mv=new ModelAndView();
List<Books> books= bookservice.getAllBooks();
model.put("books",books);
mv.setViewName("book");
return mv; }
/**

@RequestMapping("/viewone/{bookid}")

@PathVariable("bookid") long id){
ModelAndView mv=new ModelAndView();
Books book= bookservice.getByPk(id);
model.put("book",book);

return mv; } }
剩下的就是慢慢熟练罢了！
