我们可以再config中创建服务，或者在module中直接创建，利用provider创建需要this.get()匿名函数，而factory可以直接返回字符串或者对象，建议基于对象去返回。
那么这样会不会太乱，当然还有更好更直观的创建方式

app.provider("provider1",function(){
this.$get=function(){

console.log(getMessageFactory.getMessage());
});

上面案例引入了一个外部的js，该js专用于定义各种服务
/**
* Created by Administrator on 2016/3/28.
*/
var service=angular.module(‘myService‘,[]);
service.service(‘getMessageFactory‘,function(){
var service={};
service.getMessage=function(){
return "这是外置文件的js服务";
}
return service;
})
service.service(‘getMessageFactory1‘,function(){
var service={};
service.getMessage=function(){
return "这是外置文件的js服务1";
}
return service;
})
service.service(‘getMessageFactory2‘,function(){
var service={};
service.getMessage=function(){
return "这是外置文件的js服务2";
}
return service;
})
在html中的mudule要记得引入依赖关系，引入依赖之前当然你要确保你的service.js已经引入进页面中来了
