Authentication.isAuthenticated介绍

[英]Used to indicate to AbstractSecurityInterceptor whether it should present the authentication token to the AuthenticationManager. Typically an AuthenticationManager (or, more often, one of its AuthenticationProviders) will return an immutable authentication token after successful authentication, in which case that token can safely return true to this method. Returning true will improve performance, as calling the AuthenticationManager for every request will no longer be necessary.

For security reasons, implementations of this interface should be very careful about returning true to this method unless they are either immutable, or have some way of ensuring the properties have not been changed since original creation.
[中]用于向AbstractSecurityInterceptor指示是否应向AuthenticationManager提供身份验证令牌。通常，AuthenticationManager（或者更常见的是，它的AuthenticationProvider之一）在成功身份验证后将返回一个不可变的身份验证令牌，在这种情况下，该令牌可以安全地将true返回到此方法。返回true将提高性能，因为不再需要为每个请求调用AuthenticationManager。
出于安全原因，此接口的实现在将true返回到此方法时应非常小心，除非它们是不可变的，或者有某种方法确保自原始创建以来属性未被更改。
