Re: get the authenticated user in spring controller method

He Principal type depends on the Realm that you are using.
The Principal type of Map is for example purposes only.
In your code, you would substitute the type passed into byType() method with 
the appropriate type.
Or you can use Subject.getPrincipal() that returns Object type and cast to 
appropriate type manually.

Re: get the authenticated user in spring controller method

[Helge Wiemann]

Hi,

thanks for the sample code.

But I questions because I got some problems to understand the code:


    Collection principalMaps = 
subject.getPrincipals().byType(Map.class);

    if (CollectionUtils.isEmpty(principalMaps)) {
    name = subject.getPrincipal().toString();
    } else {
    name = (String) 
principalMaps.iterator().next().get("username");

    }


When the map of the principals is empty, why and how do I get then the 
logged user by getPrincipal? I would expect that a call of 
getPrincipal() is null because the map is empty.


When the map is not empty, I got the first entry of the map as 
principal. But for instance three users are logged in, how do I got the 
correct one out of the map?

Hi,

Take a look at Shiro’s SpringBoot 3 example.
This should get your started: 
https://github.com/apache/shiro/blob/main/samples/spring-boot-3-web/src/main/java/org/apache/shiro/samples/HelloController.java
 


Let us know if you have any further questions.

One question: After a user is successfully authenticated and authorized, what 
is the best way to get the user in a Spring controller method?

With used Spring Security it was something like that:

publicModelAndView 
index(*@AuthenticationPrincipalUsernamePasswordAuthenticationTokenauthenticatedUser*,

HttpServletRequest request, HttpServletResponse response) throwsIOException {


Best regards,

Hi,

Take a look at Shiro’s SpringBoot 3 example.
This should get your started: 
https://github.com/apache/shiro/blob/main/samples/spring-boot-3-web/src/main/java/org/apache/shiro/samples/HelloController.java
 


Let us know if you have any further questions.

get the authenticated user in spring controller method

[Helge Wiemann]

Hi all,

I am quite new to Shiro and currently moving from Spring Security to Shiro.


One question: After a user is successfully authenticated and authorized, 
what is the best way to get the user in a Spring controller method?


With used Spring Security it was something like that:

publicModelAndView 
index(*@AuthenticationPrincipalUsernamePasswordAuthenticationTokenauthenticatedUser*,


HttpServletRequest request, HttpServletResponse response) 
throwsIOException {



Best regards,
