首先,我要吐槽一下,我找这个简单的Demo实现,发现论坛中好多水文,千篇一律,都是复制粘贴的,好多根本都实现不了,这个水分太大了,自己写个总结,避免相同的问题再次发生,能够少走弯路。 我的实现,借鉴于此帖子。先沾出来地址 https://blog.csdn.net/weixin_33728268/article/details/86121242
.net Core的注入机制不过多赘述,直接进入正题
SystemConfig *List集合的数据源 AppSettings 实体对象的数据源
1、首先在AppSettings.json文件中,录入自己的数据源。
{ "Logging": { "LogLevel": { "Default": "Information", "Microsoft": "Warning", "Microsoft.Hosting.Lifetime": "Information" } }, "SystemConfig": [ { "Code": "10", "Name": "系统模块", "Sort": 10, "DefaultAction": "", "Children": [ { "Code": "20", "Name": "系统页面", "Sort": 20, "DefaultAction": "" } ] }, { "Code": "15", "Name": "自定义模块", "Sort": "15", "DefaultAction": "", "Children": [ { "Code": "25", "Name": "自定义页面", "Sort": 25, "DefaultAction": "" } ] }, { "Code": "500", "Name": "定制模块", "Sort": 500, "DefaultAction": "", "Children": [ { "Code": "510", "Name": "定制新增", "Sort": 510, "DefaultAction": "/home/insert" }, { "Code": "520", "Name": "定制编辑", "Sort": 520, "DefaultAction": "/home/update" } ] } ], "AllowedHosts": "*", "AppSettings": { "AccessKey": "111111", "SecretKey": "22222", "Bucket": "3333333", "Domain": "http://wwww.domain.com" } }2、在控制器中通过构造函数注入的方式,注入对象 此代码是实现List集合的方式,注释掉的地方,你可以根据你要实现的场景使用
[Route("api/[controller]/[action]")] public class HomeController : Controller { private readonly IConfiguration _configuration; private AppSettings _appSettings; private List<SystemConfig> _systemConfig; public HomeController(IOptionsMonitor<List<SystemConfig>> systemConfig) { //实现实体对象注入 //_appSettings = appSettings.CurrentValue; //实现List集合的注入 _systemConfig = systemConfig.CurrentValue; } [HttpGet] public void Index() { var aa = _configuration["SystemConfig"]; } }3、定义我们的Module对象
public class SystemConfig { public String Code { get; set; } public String Name { get; set; } public String Sort { get; set; } public String DefaultAction { get; set; } public List<Children> Children { get; set; } } public class Children { public String Code { get; set; } public String Name { get; set; } public String Sort { get; set; } public String DefaultAction { get; set; } } public class AppSettings { public string AccessKey { get; set; } public string SecretKey { get; set; } public string Bucket { get; set; } public string Domain { get; set; } }4、最关键的一步,在Startup.cs文件中,找到 ConfigureServices 方法,注册我们的对象集合即可 同理,注释掉的地方,是实现实体的地方
//var appSettings = Configuration.GetSection("AppSettings"); //services.Configure<AppSettings>(appSettings); var sysconfig = Configuration.GetSection("SystemConfig"); services.Configure<List<SystemConfig>>(sysconfig);做完这些步骤之后,Debug程序,因为我的Demo是API的方式,你可以直接通过访问路由,就可以拿到自己的实体对象
