在用户重点中可选的导致身份验证机制破裂
我正在使用Spring Boot以及Spring Security，在我的usersrepository中，我有以下代码：
public interface UsersRepository<T extends Users> extends CoreRepository<Users> {
Optional<Users> findByEmail(String email);
}
并且，在我的websecurityconfig中/code>在配置方法中，我有以下操作：
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(
username -> {
return usersRepository.findByEmail(username)
.orElseThrow(
() -> new UsernameNotFoundException("Account not found for " + username)
)
}
);
}
这弹出此错误：
当我添加try/catch（实际上不需要？）时，我会收到以下错误：
我知道这是因为usersrepository中的方法被声明为可选＆lt;用户＆gt; - 您可以使用
我需要将userDetails的实现传递给auth.userdetailsservice（）呼叫。
我需要做什么来满足这一点？
更新
这是编译器返回的错误：
[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] /D:/Projects/sitebuild/src/main/java/com/zev/installations/config/WebSecurityConfig.java:[62,33] incompatible types: cannot infer type-variable(s) T

I am using spring boot along with spring security and in my UsersRepository, I have the following code:
public interface UsersRepository<T extends Users> extends CoreRepository<Users> {
Optional<Users> findByEmail(String email);
}
And, in my WebSecurityConfig in the configure method, I have the following:
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(
username -> {
return usersRepository.findByEmail(username)
.orElseThrow(
() -> new UsernameNotFoundException("Account not found for " + username)
)
}
);
}
This pops up with this error:
When I add a try/catch (which really shouldn't be necessary?), I get the following error:
I know that this is because the method in the UsersRepository is declared as Optional<Users> - and you can retrieve the object by using .get() after the object is retrieved - but that is not what we are doing here.
I need to pass an implementation of UserDetails to the auth.userDetailsService() call.
What do I need to do to satisfy this?
Update
Here are the errors returned from the compiler:
[INFO] -------------------------------------------------------------

满足UserDetails合同的最简单方法：
使用此小更改，代码编译确定。
另一个是使用Spring Security提供的用户而不是用户。
The simplest way to satisfy UserDetails contract:
With this small change the code compiles OK.
Another, is to use Spring Security provided User instead of Users.
