If Spring Security is on the classpath, then web applications are
secured by default. Spring Boot relies on Spring Security’s content-negotiation strategy
to determine whether to use The default Using generated security password: 78fa095d-3f4c-48b1-ad50-e24c31d5cf35
You can change the username and password by providing a The basic features you get by default in a web application are:
You can provide a different The default security configuration is implemented in To also switch off the Access rules can be overridden by adding a custom Similar to Spring MVC applications, you can secure your WebFlux applications by adding
the To also switch off the Access rules can be configured by adding a custom
For example, you can customize your security configuration by adding something like: @Bean public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) { return http .authorizeExchange() .matchers(PathRequest.toStaticResources().atCommonLocations()).permitAll() .pathMatchers("/foo", "/bar") .authenticated().and() .formLogin().and() .build(); } OAuth2 is a widely used authorization framework that is supported by Spring. If you have You can register multiple OAuth2 clients and providers under the

we provide a set of provider defaults ( If you do not need to customize these providers, you can set the In other words, the two configurations in the following example use the Google provider: spring.security.oauth2.client.registration.my-client.client-id=abcd spring.security.oauth2.client.registration.my-client.client-secret=password spring.security.oauth2.client.registration.my-client.provider=google spring.security.oauth2.client.registration.google.client-id=abcd spring.security.oauth2.client.registration.google.client-secret=password Currently, Spring Security does not provide support for implementing an OAuth 2.0
Authorization Server or Resource Server. However, this functionality is available from
the Spring Security OAuth project,
which will eventually be superseded by Spring Security completely. Until then, you can
use the For security purposes, all actuators other than If Spring Security is on the classpath and no other WebSecurityConfigurerAdapter is
present, the actuators are secured by Spring Boot auto-config. If you define a custom
Since Spring Boot relies on Spring Security’s defaults, CSRF protection is turned on by
default. This means that the actuator endpoints that require a
