解决JSP调用JavaBean出现乱码问题
话不多说放代码

Javabean文件没啥问题。可是Index.jsp黄色高亮部分都是utf-8了也还是会乱码
只需在index.jsp中插入
<meta http-equiv="content-type" content="text/html; charset=GB2312">
并把上述高亮部分utf-8全部改为GB2312即可
或者
在index.jsp中插入
<meta http-equiv="content-type" content="text/html; charset=utf-8">
高亮部分全写utf-8
更改后的index.jsp如下：
1 <%@ page import="school.stu.StudentForm" language="java" contentType="text/html; charset=GB2312"//或utf-8(原谅这个c++风格的注释） 2 pageEncoding="GB2312" %>//或utf-8 3 <!-- page import="包名.类名" 引入包 --> 4 <% request.setCharacterEncoding("GB2312");%>//或utf-8 5 <!DOCTYPE html> 6 <html> 7 <head> 8 <meta http-equiv="content-type" content="text/html; charset=GB2312">//或utf-8 9 <meta charset="GB2312">//或utf-8 10 <title>学生信息</title> 11 12 </head> 13 <body> 14 <center> 15 <form action="" method="post" name="addform"> 16 学 号：<input type="text" name="number"><br> 17 姓 名：<input type="text" name="name"><br> 18 性 别：<input type="text" name="gender"><br> 19 年 龄：<input type="text" name="age"><br> 20 电 话：<input type="text" name="phone"><br> 21 电子邮件：<input type="text" name="email"><br> 22 住 址：<input type="text" name="address"><br> 23 <input type="submit" value="提交" name="submit"> 24 <input type="reset" value="重置"> 25 26 </form> 27 </center> 28 <jsp:useBean id="student" class="school.stu.StudentForm" scope="request"></jsp:useBean> 29 <!-- id给bean起的名字 | class bean类 |scope 指定对象的范围 --> 30 31 <!-- <jsp:setProperty name="student" property="number" 32 value="201711010111"/> 33 --> 34 35 <jsp:setProperty name="student" property="number" 36 param="number"/> 37 <jsp:setProperty name="student" property="name" 38 param="name"/> 39 <jsp:setProperty name="student" property="gender" 40 param="gender"/> 41 <jsp:setProperty name="student" property="age" 42 param="age"/> 43 <jsp:setProperty name="student" property="phone" 44 param="phone"/> 45 <jsp:setProperty name="student" property="email" 46 param="email"/> 47 <jsp:setProperty name="student" property="address" 48 param="address"/> 49 <!-- 通过HTTP表单的参数的值来设置bean的相应属性的值 --> 50 51 <jsp:getProperty name="student" property="number"/><br/> 52 <jsp:getProperty name="student" property="name"/><br/> 53 <jsp:getProperty name="student" property="gender"/><br/> 54 <jsp:getProperty name="student" property="age"/><br/> 55 <jsp:getProperty name="student" property="phone"/><br/> 56 <jsp:getProperty name="student" property="email"/><br/> 57 <jsp:getProperty name="student" property="address"/><br/> 58 <!-- 59 <jsp:getProperty name="student" property="name"/> 60 <jsp:getProperty name="student" property="name"/> 61 <jsp:getProperty name="student" property="name"/> 62 <jsp:getProperty name="student" property="name"/> 63 <jsp:getProperty name="student" property="name"/> 64 <jsp:getProperty name="student" property="name"/> --> 65 66 <!-- 获得bean的属性值,并将这个值以字符串的形式显示给用户 --> 67 68 </body> 69 </html>
完美！！
