Field httpRequest in "project package" required a bean of type 'jakarta.servlet.http.HttpServletRequest' that could not be found

Question

I'm pretty new to Maven and Java itself.

I'm trying to run my project's .jar file that is produced after running :

1. maven install clean

2. maven package

When I run the jar file, I get the following error :

I have tried several solutions online but still cannot make sense of it or how to resolve it. I can edit this question and share my pom.xml file if necessary. this is the dependency version I am using :

  <dependency>
      <groupId>jakarta.servlet</groupId>
      <artifactId>jakarta.servlet-api</artifactId>
      <version>6.0.0</version>
      <scope>provided</scope>
  </dependency>

Answer 1

Remove the @Autowired from the httpRequest variable in the ApiController, you shouldn't have a bean of type HttpServletRequest, that's an object that gets created for each request. You can add a HttpServletRequest parameter to any method in your controller class that is annotated to be a HTTP method (@GetMapping) and Spring will automatically initialize the parameter with a reference to the current HttpServletRequest.

Scope provided means that the dependency should be provided at runtime by JDK or a container. You have 2 options:

Option 1. Remove the scope:

  <dependency>
      <groupId>jakarta.servlet</groupId>
      <artifactId>jakarta.servlet-api</artifactId>
      <version>6.0.0</version>
  </dependency>

Option 2. Add the dependency to the classpath:

java -classpath <path_to_jakarta_api> -jar <your_jar>

just be careful that the second option overrides the entire classpath so if you have some other jars in your current folder or elsewhere seperate them with ;.

Example: -classpath .;lib;<path_to_jakarta> this will search in current folder, lib subfolder, and path

Option 3: If you have a web application and use Tomcat keep the <scope>provided</scope> since those will be included in the classpath automatically by Tomcat.
