$.post与springmvc数据交互

js代码

$(document).ready(function(){    $(".submit_btn").click(function(){        var flag = false;        manageName = $("#manageName").val();        managePwd = $("#managePwd").val();        alert(manageName);        alert(managePwd);        if(manageName == ""){            alert("请输入用户名");        }else if(managePwd == ""){            alert("请输入密码");        }else if(!validate()){            alert("验证码错误");        }else{            flag = true;            alert("可以提交");            login();        }    });    function login(){        $.post('/ACGshopping/login.action',                {manageName : manageName,managePwd : managePwd},                function(data){                    if(data == "success"){                        alert("登录成功!");                        //location.href="showManage.action";                    }else{                        alert("账户或密码错误!");                    }        },"text");    }});

springmvc中controller代码

    //通过用户名验证密码    @RequestMapping("/login")    public void login(String manageName, String managePwd,HttpServletResponse response) throws IOException{        Manage manage = null;        String str;        manage = manageService.selectByManageName(manageName);        if(manage!=null){            str = "success";        }else{            str = "fail";        }        PrintWriter out = response.getWriter();        out.write(str);        out.close();    }
