使用model來存放數據時，不能直接用，必須用他的實現類ModelMap
話不多說，直接整個代碼來看一下：
public class Account implements Serializable {
private String username;
private String password;
private Double money;
private User user;
//getter/setter
//tostring
}
public class User implements Serializable {
private String username;
private String password;
//getter/setter
//tostring
}
@Controller
@RequestMapping("/user")
public class SpringMVCHandler {
@RequestMapping("/textPojo")
public String testPojo(Account account){
ModelMap modelMap = new ModelMap();
System.out.println("pojo....");
System.out.println(account);
modelMap.addAttribute("account",account);
return "success";
}
}
<form action="user/textPojo" method="post">
用戶名：<input type="text" name="username"/><br/>
密碼：<input type="text" name="password"/><br/>
金額：<input type="text" name="money"/><br/>
user用戶：<input type="text" name="user.username"/><br/>
user金額：<input type="text" name="user.password"/><br/>
<input type="submit" value="提交"/>
</form>
注意在這裏，文件頭上必須加isELIgnored=“false”
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h2>success!</h2>
<br/>
<%--獲取requestSope中的值--%>
${account}
</body>
</html>
運行並查看結果：
