Java 自动装配依赖项的注入失败；嵌套异常是 org.springframework.beans.factory.BeanCreationException 如何解决

Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException How to resolve it

提问by Jai Prak

Can anyone suggest any link from where I can learn how to create simple login app using SpringBoot Rest API, WebSecurity and MySQL. These are my logs. It seems it's not injecting the bean to security config.

任何人都可以建议任何链接，我可以从中学习如何使用 SpringBoot Rest API、WebSecurity 和 MySQL 创建简单的登录应用程序。这些是我的日志。似乎它没有将 bean 注入安全配置。

apply plugin: 'spring-boot'

         containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8'
    }
}

I don't know what's happening here. Can anyone tell me why its happening and how to resolve it.

我不知道这里发生了什么。谁能告诉我为什么会发生以及如何解决它。

Without waiting for application.properties or application.yml as I mentioned in my comment, I'm almost 100% sure that You're missing value for 'spring.datasource.driverClassName' in one of files mentioned above.

无需等待我在评论中提到的 application.properties 或 application.yml，我几乎 100% 确定您在上述文件之一中缺少“spring.datasource.driverClassName”的值。

Read more about external configuration in Spring Boot at: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html

阅读有关 Spring Boot 中外部配置的更多信息：https: //docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html

Anyway, this part of code:

无论如何，这部分代码：

@Value("${spring.datasource.driverClassName}")
private String databaseDriverClassName;

@Value("${spring.datasource.url}")
private String datasourceUrl;

@Value("${spring.datasource.username}")
private String databaseUsername;

@Value("${spring.datasource.password}")
private String databasePassword;

@Bean
public DataSource datasource() {
    org.apache.tomcat.jdbc.pool.DataSource ds = new org.apache.tomcat.jdbc.pool.DataSource();
    ds.setDriverClassName(databaseDriverClassName);
    ds.setUrl(datasourceUrl);
    ds.setUsername(databaseUsername);
    ds.setPassword(databasePassword);

    return ds;
}

can be omnited. When you provide dependency for database driver (mysql in this example) the database connection details are configured by spring boot autoconfiguration. Only configuration that is needed here is database specifics like url, username password etc. definied inside application.properties/application.yml

可以是万能的。当您为数据库驱动程序（本例中为 mysql）提供依赖项时，数据库连接详细信息由 Spring Boot 自动配置配置。这里唯一需要的配置是在 application.properties/application.yml 中定义的数据库细节，如 url、用户名密码等

Example here:
