Spring 数据传入

表单传入

         前端代码：

<form method="POST" id="user_login_submit">
                                <div class="form-group">
                                    <label for="email">E-Mail Address</label>
                                    <input id="email" type="email" class="form-control" name="email" value="" required autofocus>
                                </div>

                                <div class="form-group">
                                    <label for="password">Password
                                        <a href="forgot.html" class="float-right">
                                            Forgot Password?
                                        </a>
                                    </label>
                                    <input id="password" type="password" class="form-control" name="password" required data-eye>
                                </div>

                                <div class="form-group">
                                    <label>
                                        <input type="checkbox" name="remember"> Remember Me
                                    </label>
                                </div>

                                <div class="form-group no-margin">
                                    <button id="login_btn" type="submit" class="btn btn-primary btn-block">
                                        Login
                                    </button>
                                </div>
                                <div class="margin-top20 text-center">
                                    Don't have an account? <a href="register.html">Create One</a>
                                </div>
                            </form>

$(function () {
    $("#user_login_submit").submit(function () {
        $.ajax({
            url: "/bengmall/login",
            type: "post",//方法类型
            dataType: "json",//预期服务器返回的数据类型
            success: function (data) {
                console.log("提交成功");
            },
            error: function (data) {
                alert("登录過程中出現錯誤！"+data.result["result"].message);
            }
        })
    });
});

         前端中传入了一个name 为 email , 一个为 password , 后端使用了一个类来接收数据

@RequestMapping(value = "/login")
    public String login(User user, HttpServletRequest request, HttpServletResponse response) {

    ... 

}

public class User
{
    private String email;
    private  String password;

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

    

URL 路径

         当传递一些不重要的数据时,只是为了查询使用时,可以通过URL 路径中放置参数查询。

@PathVariable

//http://weibo.com/user1,http://weibo.com/user2
@RequestMapping("/usermanager/{username}")
public String userManager(@PathVariable("username")String name )
{
    return "usermanager";
}

@RequestParam

   // http://localhost:8080/springmvc/hello/101?param1=10&param2=20
   public String getDetails(
           @RequestParam(value="param1", required=true) String param1,
           @RequestParam(value="param2", required=false) String param2){
        ...
   }
