介绍
本文介绍springmvc获取前台参数
前台页面
<form action="login" method="post">
用户名：<input type="text" name="username" > <br/>
密码：<input type="text" name="password" > <br/>
<input type="submit" value="登录">
</form>
Controller形参自动匹配
@RequestMapping("/login")
public String login(String username,String password){
System.out.println("username："+username);
System.out.println("password："+password);
return "success";
}
Controller形参绑定
@RequestMapping("/login")
public String login(@RequestParam("username") String name,@RequestParam("password") String pwd){
System.out.println("username："+name);
System.out.println("password："+pwd);
return "success";
}
Controller形参是javabean
创建User类，如下
public class User {
private String username;
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
Controller：
@RequestMapping("/login")
public String login(User u){
System.out.println("username："+u.getUsername());
System.out.println("password："+u.getPassword());
return "success";
}
