Nacos-SpringBoot框架啟動不載入bootstrap.yml的解決

背景

nacos server 原始碼執行在本地自己建立的專案中。

正常啟動的話，SpringBoot框架會自動載入resource目錄下的bootstrap.yml檔案中的設定，紀錄檔記錄會列印相關紀錄檔：

但是我把這塊的nocos程式碼原封不動的copy到的自己的一個專案中，修改了bootstrap.yml檔案中的資料庫連線。

然後啟動紀錄檔列印卻顯示使用的是embedded storage。

紀錄檔如下：

原因

原因一

看紀錄檔應該發現是服務沒有讀取到bootstrap.yml檔案中的設定。應該就是定位到是bootstrap.yml沒有被載入。

只要全域性引入bootstrap 啟動器和組態檔處理器就可以解決這個問題

        <!--bootstrap 啟動器-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-bootstrap</artifactId>
        </dependency>
        <!--組態檔處理器-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <optional>true</optional>
        </dependency>
        <!--組態檔加解密-->
        <dependency>
            <groupId>com.github.ulisesbocchio</groupId>
            <artifactId>jasypt-spring-boot-starter</artifactId>
            <version>${jasypt.version}</version>
        </dependency>

原因二

也有可能是自己pom檔案排除掉了相關結尾的檔案，刪掉過濾器就行。

    <build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
    </build>

以上為個人經驗，希望能給大家一個參考，也希望大家多多支援it145.com。
