AngularJS内置服务$http的使用（对数据库的增删改）

1.使用$http查询@R_404_198@数据

angular.module('app',[])
.controller('MyCtrl',function ($scope,$http) {
    $http.get('http://127.0.0.1:80/user/getUsers')
    .success(function (resp) {
        console.log(resp);
    })
    .error()
    //jQuery  /*$.get('url',function (data) {   });*/ })

对应的后台Java代码：

public void getUsers(){
List<User> users = User.dao.find("select * from t_user");
renderJson(Users);
}

2.$http实现对数据的增删改

(1)$http带参数发送请求

(2)对@R_404_198@数据增删改

controller('MyCtrl',$http) {
        $scope.id=" ";
        $scope.name=" ";
        $scope.addUser = function () {
            $http.post('http://127.0.0.1:80/user/addUser',{id:$scope.id,name:$scope.name})
                .success(function (resp) {
                    if(resp.success){
                        alert("添加成功");
                    }
                })
        }
        $scope.delUser = function () {
            $htp.post('http://127.0.0.1:80/user/delUser',{id:$scope.id})
            .success(function () {
                if(resp.success){
                    alert('删除成功');
                }
            })
        }
    })

后台Java代码：

public void addUser(){ String id = getPara("id"); String name = getPara("name"); User user = new User(); boolean isok = false; if(id != null && id.equals("")){ isok = user.set("id",id).set("name",name).update(); }else{ isok = user.set("name",name).save(); } renderJson("seccess",isok); } public void delUser(){ String id = getPara("id"); boolean isok = User.dao.deleById(id); renderJson("seccess",isok); }
