如果有人能够确定我哪里出错了,我将不胜感激.

的index.html

<!DOCTYPE html>
<html ng-app="ResolveTest">
  <head>
    <title>Resolve Test</title>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.js">    </script>
    <script src="ResolveTest.js"></script>
  </head>
  <body ng-controller="ResolveCtrl">

ResolveTest.js

var rt = angular.module("ResolveTest",[]);

rt.config(["$routeProvider",function($routeProvider)
{
  $routeProvider.when("/",{
    templateUrl: "rt.html",
    controller: "ResolveCtrl",
    resolve: {
      data: ["$q","$timeout",function($q,$timeout)
      {
        var deferred = $q.defer();

        $timeout(function()
        {
          deferred.resolve("my data value");
        },2000);

        return deferred.promise;
      }]
    }
  });
}]);

rt.controller("ResolveCtrl",["$scope","data",function($scope,data)
{
  console.log("data : " + data);
  $scope.data = data;
}]);

问题是你ng-controller="ResolveCtrl"在index.html中的body标签上也有你在$ routeProvider中为rt.html指定相同的控制器.从body标签中取出控制器定义,然后让$ routeProvider处理它.之后效果很好.
