Spring Security多个UserDetailsService

Spring Security支持多个UserDetailsService。你可以通过在配置文件中定义多个UserDetailsService的实现类来实现这一点。在配置文件中，你可以使用<bean>标签为每个UserDetailsService定义一个bean，并使用<alias>标签为每个bean定义一个别名。然后，你可以在Spring Security的配置中使用这些别名来引用不同的UserDetailsService。这样，当Spring Security进行认证时，它将根据配置中指定的别名来选择相应的UserDetailsService来获取用户的认证数据。这种方式可以实现对不同来源的用户数据的支持，例如内存、数据库、LDAP等。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
