Spring Security-没有可用的javax. sql.DataSource类型的合格bean：预计至少有1个bean有资格作为自动配线候选者


我试图从Spring Security留档中重复，并试图保护一个网页作为测试。我严格按照Spring编写的留档做所有事情。

Spring文档-1
Spring文档-2
Spring文档-3

但它不起作用。我已经被这个问题折磨了7天。我快疯了。我不知道该怎么办，如何克服这个错误。它发生在项目的组装阶段。谁能帮忙请。

这里是错误日志：

显然您的WebSecurityConfig在SQLConfig中找不到bean。修改MessageWebApplicationStaralizer；尝试将SQLConfig. class放在getRootConfigClass（）中：

@Override
protected Class<?>[] getRootConfigClasses() {
    return new Class<?>[]{ WebSecurityConfig.class, SQLConfig.class};
}

@Override
protected Class<?>[] getServletConfigClasses() {
    return new Class<?>[]{FreeMarkerConfig.class };
}

// ...

getRootConfigClass（）中的所有配置类都用于创建父应用程序上下文，getServletConfigClass（）中的配置类是子上下文。子上下文可以@Autowireroot-context bean，但不能反过来。
