我正在使用 postgres 数据库开发一个 spring 安全应用程序，但我无法解决这个错误:

这是 spring-security-configuration.xml

  </authentication-provider>
</authentication-manager>

有人可以识别问题吗？我花了很多时间来解决这个问题，但仍然能找出问题所在。

确保你的类路径中有 spring-security-core-$version

如果你使用maven，添加这个依赖

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <version>${spring.security.version}</version>
</dependency>
