我知道这是因为我的 ~/.m2/ 存储库中的一个或多个 jar 文件已损坏，但我实际上无法确定哪些 jar 文件已损坏或哪些 jar，我需要删除并重新-下载。

我需要在运行时阅读所有装饰有特定注释（例如@HttpSecurity）的类（接口）。扫描后，我希望阅读和解析装饰有注释的类的字段（枚举字段）。例如。

@HttpSecurity
public interface MyHttpSecurityConfig {

public enum secure {
    @Path(pathGroup = "/*", pathName = "")
    @Authc
    @Form(errorPage = "/error.html", loginPage = "/login.html", restoreOriginalRequest = "")
    @Authz
    @AllowedRoles(roles = { "roleA", "roleB" })
    @AllowedGroups(groups = { "groupA" })
    @AllowedRealms(realms = { "realmA" })
    @Expressions(expressions = { "#{identity.isLoggedIn()}" })
    Admin
  }
}

可能存在一个或多个用@HttpSecurity装饰的类/接口。我的第一个要求是获取所有此类，第二个要求是通过读取注释及其在枚举字段上修饰的值来构建HttpSecurityBuilder。第二个要求很好，可以使用反射消除。但是，我的问题是第一个要求。我想用JavaSE核心实现第一个要求，即不使用任何外部依赖项，例如google Reflections。如有必要，可以假定我们具有要在其中扫描类的程序包名称。这是我做过什么用CDI
