## Spring Security
```
Filter -> Interceptor -> Aspect -> Controller
OncePerRequestFilter 重复执行的filter只需要一次执行

1. AbstractUserDetailsAuthenticationProvider.java
     private class DefaultPostAuthenticationChecks implements UserDetailsChecker
         -> isAccountNonLocked() -> isEnabled() -> isAccountNonExpired()
2. DaoAuthenticationProvider.java
     protected void additionalAuthenticationChecks
         -> check username and password
3. AbstractUserDetailsAuthenticationProvider.java
     private class DefaultPreAuthenticationChecks implements UserDetailsChecker
         -> isCredentialsNonExpired()

USERNAME_NOT_FOUND(1004, "认证失败：用户名不存在"),
BAD_CREDENTIALS(1005, "认证失败：密码错误"),
ACCOUNT_DISABLED(1006, "认证失败：用户不可用"),
ACCOUNT_LOCKED(1007, "认证失败：用户锁定"),
ACCOUNT_EXPIRED(1008, "认证失败：用户过期"),
CREDENTIALS_EXPIRED(1009, "认证失败：证书过期"),
```
