本文主要介绍的是Angular.JS内置服务$http对数据库的增删改操作的相关内容，分享出来供大家参考学习，下面来看看详细的介绍：
一、使用$http查询MySQL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);
}
二、$http实现对数据的增删改
(1)$http带参数发送请求
(2)对MySQL数据增删改

<link rel="stylesheet" href="css/foundation.min.css" rel="external nofollow" >

</style>
</head>
<body style="padding:10px;" ng-app="app">
<div ng-controller="MyCtrl">
<input type="text" ng-model="id">
<input type="text" ng-model="name">
<button class="button" onclick="addUser()">添加</button>
<button class="button" onclick="delUser()">删除</button>
</div>
</body>
<script src="js/angular.min.js"></script>
<script src="app.js"></script>
</html>
angular.module('app', [])
.controller('MyCtrl', function ($scope, $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);
}
