Q: javax.servlet.http.httpservletrequest cannot be resolved after upgrading spring boot version Recently I have upgraded the spring boot version of my project from 2.5.3 to 2.5.12 and 2.6.6. In both versions, the same issue appear.
javax.servlet.http.httpservletrequest cannot be resolved
I tried adding the dependency in my pom.xml as below.
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <scope>provided</scope>
</dependency>

However, the other issues came out after solving the issue above.
The import org.springframework.boot.SpringApplication cannot be resolved
The import org.springframework.boot.autoconfigure.SpringBootApplication cannot be resolved
The import org.springframework.boot.context.properties.EnableConfigurationProperties cannot be resolved
What should I do to fix this?
