我正在设置Spring项目以使用Spring Security。
我想使用JDBC身份验证并连接到MySQL数据库。
我无法使用@Autowired创建bean。
我用Gradle建立了我的春季项目。当我启动tomcat时，看到如下错误消息。

registry.addViewController("/login").setViewName("general/login");
}
}

我希望已创建BasicDataSource对象，并查看登录页面。
答案 0 :(得分：1)
您的项目找不到datasourceBean，
更改
@ComponentScan("(my top level package name).controller")
以包含DataSourceConfig类包
例如DataSourceConfig位于软件包my.test.package.DataSourceConfig
至少ComponentScan应该是
@ComponentScan(`my.test.package")
