问题：angularjs调用url: /admin/query , action方法已经进去了，数据也查询到了，但是数据angularjs controller.js中无法获取到，浏览器中看到/admin/admin/query地址的调用(不知道为啥多加了个/admin)，都报404错了。
解决：springMVC action方法必须要增加注解@ResponseBody。

action:
@Controller
@RequestMapping("/admin")
public class LoginAction {
private static final Logger log = LoggerFactory.getLogger(LoginAction.class);
@Resource(name = "mAdminBO")
private MAdminBO mAdminBO;
@RequestMapping("/query")
@ResponseBody

// try {

// } catch (Exception e) {
// log.error("", e);
// }
log.info("query result:{}", ret);
return ret;
}
app.js:
// 模块可以按任意的顺序定义,模块要先定义，后使用
angular.module(‘myApp‘, [‘ctrl‘,‘ngResource‘]);
angular.module(‘ctrl‘, [‘svc‘]);
angular.module(‘svc‘, []);
controllers.js:
angular.module(‘ctrl‘);
var app=angular.module(‘myApp‘);
app.controller(‘usernameCheckCtrl‘,function($scope,MAdminSvc){
//失去焦点，校验username
/*$scope.checkUsername=function(){
if($scope.username=="zgx"){
$scope.isUsernameExisted=true;
}else{
$scope.isUsernameExisted=false;
}
}
*/
//实时校验
$scope.$watch(‘username‘,
function(to,from){
console.log("--username="+$scope.username);
var promise=MAdminSvc.query($scope.username);// 同步调用，获得承诺接口
promise.then(function(data){// 调用承诺API获取数据 .resolve
console.log("admin="+data.admin);
if($scope.username==data.admin){
$scope.isUsernameExisted=true;
}else{
$scope.isUsernameExisted=false;
}
},function(data){//处理错误 .reject
console.log("err: "+data);
$scope.isUsernameExisted=false;
})
}
)
});
services.js:
angular.module(‘svc‘);
var app=angular.module(‘myApp‘);
//使用factory定义服务:通过admin查询M_ADMIN数据
app.factory(‘MAdminSvc‘, [‘$http‘,‘$q‘,function ($http,$q) {
return {
query:function(admin){
var deferred=$q.defer();
if(admin==null||admin==""){
return deferred.promise;
}
$http({
method:‘POST‘,
//headers: {‘Content-type‘: ‘application/json;charset=UTF-8‘},
url:‘/admin/query‘,
responseType:‘json‘,
params: {‘admin‘:admin}
}).success(function(data,status,headers,config){
console.log(data+"==="+data.admin);
deferred.resolve(data);//成功，返回数据
}).error(function(data,status,headers,config){
console.log("status="+status);
deferred.reject(data);//失败，返回错误信息
});
return deferred.promise;// 返回承诺，这里并不是最终数据，而是访问最终数据的API
}
};
}])
angularjs调用springmvc action时，访问到action但是数据不能正确返回到angular controller中
