jsp中使用javabean

方法一:

在头部添加指令引入class，然后直接在页面嵌入java代码

<%@ page import="com.zzy.bean.Book"%>
<%
    Book book = new Book();
    book.setId(1);
    book.setAuthor("鲁迅");
    book.setTitle("狂人日记");
%>
<table cellpadding="3" cellspacing="3">
    <table cellpadding="3" cellspacing="3">
        <tr>
            <td>图书编号:</td>
            <td><%= bk.getId() %></td>
        </tr>
        <tr>
            <td>图书名称:</td>
            <td><%= bk.getTitle() %></td>
        </tr>
        <tr>
            <td>图书作者:</td>
            <td><%= bk.getAuthor() %></td>
        </tr>
    </table>
</table>

方法二:

使用<jsp:useBean><jsp:setProperty><jsp:getProperty>动作标签

/*导入类文件*/
<jsp:useBean id="book" class="com.zzy.bean.Book"></jsp:useBean>

<jsp:setProperty property="id" name="book" value="1"></jsp:setProperty>
<jsp:setProperty property="title" name="book" value="狂人日记"></jsp:setProperty>
<jsp:setProperty property="Author" name="book" value="鲁迅"></jsp:setProperty>
 
    <table cellpadding="3" cellspacing="3">
        <tr>
            <td>图书编号:</td>
            <td><jsp:getProperty property="id" name="book"/><br></td>
        </tr>
        <tr>
            <td>图书名称:</td>
            <td><jsp:getProperty property="title" name="book"/><br></td>
        </tr>
        <tr>
            <td>图书作者:</td>
            <td><jsp:getProperty property="author" name="book"/><br></td>
        </tr>
    </table>
