The import org.springframework.web cannot be resolved

Explanation:

The error message “the import org.springframework.web cannot be resolved”
typically occurs when the required Spring Web module is missing from the
project’s dependencies or the necessary libraries are not properly
configured.

To resolve this issue, you need to make sure that you have added the
necessary dependencies to your project’s build configuration file (e.g.,
pom.xml for Maven or build.gradle for Gradle). Below is an example of how
to add the Spring Web dependency using Maven:

      <!-- pom.xml -->
      <dependencies>
        <!-- other dependencies -->
        <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-web</artifactId>
          <version>2.5.2</version>
        </dependency>
      </dependencies>
    

In the above example, the
spring-boot-starter-web
dependency is added to the project’s dependencies. You may need to adjust
the version number based on your specific requirements.

After adding the necessary dependencies, you should rebuild your project to
ensure that the libraries are properly downloaded and imported. Once the
build process is complete, the error message should no longer occur, and
you should be able to import and use the
org.springframework.web classes without any issues.
