springboot 幾種屬性配置獲取

整個專案結構：

1.通過 environment 去獲取屬性配置值

2.通過類註解@component 獲取類物件，再通過物件獲取屬性值，通過 @value("$") 給對應屬性賦值或者新增預設值

3.通過註解//@component @configurationproperties(prefix = "gerry.properties") 類來給對應屬性賦值

4.通過@configuration 建立註解，再方法中建立對應的物件方法

同級目錄properties檔案優先於yaml檔案屬性，-d設定優先 properties檔案

以下為原始碼：

public static void main(string args) ") 給對應屬性賦值或者新增預設值

* */

redisconfig redisconfig = context.getbean("redisconfig", redisconfig.class);

system.out.println("redis:"+redisconfig.getport()+" || "+redisconfig.gethost()+" || "+redisconfig.getauth());

/** 3.通過註解//@component @configurationproperties(prefix = "gerry.properties") 類來給對應屬性賦值

* * */

datasources datasources = context.getbean(datasources.class);

string s = datasources.tostring();

system.out.println("datasout:"+s);

/** 4.通過@configuration 建立註解，再方法中建立對應的物件方法

* */

datasourceconfig bean = context.getbean(datasourceconfig.class);

datasources datasources1 = bean.getdatasources();

system.out.println("username::"+datasources1.getusername()); }}
