IDEA啟動Springboot報錯問題

1.😡 No MyBatis mapper was found in '[com.markhub.service]' package. Please check your configuration.

谷歌翻譯一下😀：在“[com.markhub.service]”包中未找到 MyBatis 映射器。 請檢查您的配置。

解決：找到項目下的SpringBootApplication在后面加上(exclude={DataSourceAutoConfiguration.class，HibernateJpaAutoConfiguration.class})

• exclude，排除此類的AutoConfig，即禁止 SpringBoot 自動注入數據源配置。
• DataSourceAutoConfiguration.class 會自動查找 application.yml 或者 properties 文件里的 spring.datasource.* 相關屬性並自動配置單數據源。

2.😡 Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2021-07-03 14:25:52.570 ERROR 11364 --- [ restartedMain] o.s.boot.SpringApplication : Application run failed

這個問題在網上看了很多博客，每個大牛的解決方法都不一樣。

接着往下看控制台打印的日志

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.markhub.mapper.BlogMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

產生問題的原因在於，沒有配置mapper層的掃描，解決辦法如下：

加上掃描路徑就好了

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class},scanBasePackages = "com.markhub.mapper") 
public class VueblogApplication {

    public static void main(String[] args) {
        SpringApplication.run(VueblogApplication.class, args);
    }

}
