Compile error in (Step 25 - Getting Started with JWT and Spring Security)

[MouathMohammad]

Compile error details :
the line # 152 : .requestMatchers("/authenticate").permitAll()
the error details :
java: method requestMatchers in class org.springframework.security.config.annotation.web.AbstractRequestMatcherRegistry cannot be applied
to given types; required: org.springframework.security.web.util.matcher.RequestMatcher[]
found: java.lang.String
reason: varargs mismatch; java.lang.String cannot be converted to org.springframework.security.web.util.matcher.RequestMatcher

the problem description :
the requestMatchers(String) method is not available in the version of Spring Security 6+. Starting with Spring Security 6, the requestMatchers method has been updated to be more type-safe and flexible

Any advice Please !!

Hey @MouathMohammad I was having a similar issue before this step with the Basic Authentication.

This issue arises because of the version of Spring Security being used (I am using Spring Security Config v6.0.0-M6 as of writing this response).

Since making the switch from .antMatchers(HttpMethod.OPTIONS, "/**").permitAll() to .requestMatchers(HttpMethod.OPTIONS, "/**").permitAll() it will generate an error like the one you are reporting because Spring Security 6's implementation of this does not require a String value passed to .requestMatchers() but a RequestMatcher object.

From AbstractRequestMatcherRegistry.class:

public C requestMatchers(RequestMatcher... requestMatchers) {
        Assert.state(!this.anyRequestConfigured, "Can't configure requestMatchers after anyRequest");
        return this.chainRequestMatchers(Arrays.asList(requestMatchers));
    }

Since Spring Security API's has been updated I have implemented this line:

.requestMatchers(new AntPathRequestMatcher("/**", HttpMethod.OPTIONS.name())).permitAll()

Using the method overload will resolve the issue you are facing.

@MaestroAD can I start working on this issue?
