SpringBoot 啟動失敗 Failed to determine a suitable driver class 問題解決方案

Description:

Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active)
 

(一) 、啟動時不需要資料來源載入，但載入了資料來源，資料來源獲取失敗，異常報錯，啟動失敗。

解決方法：

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)//去掉資料來源
public class MySpringBootApplication {

    public static void main(String[] args) {

        SpringApplication.run(MySpringBootApplication.class,args);
    }
}

（二）、有資料來源依舊報錯，配置檔案沒有載入成功

  可以嘗試在pom.xml檔案的build標籤中加入如下內容：
  <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.yml</include>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.yml</include>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
