Our Perspective on Resolving "Cannot Resolve Symbol 'WebSecurityConfigurerAdapter'" Error in Spring Boot
Upon encountering the "Cannot Resolve Symbol 'WebSecurityConfigurerAdapter'" error in Spring Boot, we acknowledge that this issue may arise due to changes in the latest versions of the Spring Boot library. The class WebSecurityConfigurerAdapter
have been removed.
To address this, we recommend trying the following solutions:
1. Use @EnableWebSecurity Annotation:
Annotate your class with @EnableWebSecurity
at the class level before extending the WebSecurityConfigurerAdapter
. This annotation enables Spring Security's web security support and might resolve the issue.
2. Change Spring Boot Version:
If the above solution doesn't work, consider changing the version of Spring Boot in your pom.xml
file. You can update the spring-boot-starter-parent
version to an earlier or specific version where WebSecurityConfigurerAdapter
is still available.
org.springframework.boot
spring-boot-starter-parent
2.5.0

Our Perspective on Upgrading the Deprecated WebSecurityConfigurerAdapter in Spring Security
As we navigate through the process of upgrading the deprecated WebSecurityConfigurerAdapter
in Spring Security, we recognize the importance of configuring HTTP security effectively. To avoid deprecation for HTTP security, we have the option to create a SecurityFilterChain
bean.
For instance, if our objective is to secure endpoints based on roles while allowing anonymous access only for login, and to restrict delete requests to users with admin roles, we can achieve this by exposing a SecurityFilterChain
bean.
1. Creating a SecurityFilterChain Bean:
We will define a custom SecurityFilterChain
bean to replace the deprecated WebSecurityConfigurerAdapter
. This bean allows us to configure HTTP security in a more modern and flexible manner.
2. Defining Security Rules:
Within the SecurityFilterChain
bean, we'll define security rules to secure endpoints based on roles. We'll also specify an anonymous entry point for login and restrict delete requests to users with admin roles.
3. Using Basic Authentication:
We'll utilize Basic Authentication to authenticate users and authorize access to protected endpoints based on their roles. This approach ensures a secure and standardized method of authentication.
Transitioning from WebSecurityConfigurerAdapter
to SecurityFilterChain
aligns with Spring Security's evolution and promotes best practices in security configuration.
By adopting modern security practices and leveraging the flexibility offered by SecurityFilterChain
beans, we can effectively address deprecation warnings and maintain a robust security architecture in our Spring applications.
