This usually happens when the path or URL does not correspond to the valid address of the requested resource. Here are few solutions to address the issue:
- Check for typos, spellings ,extra spaces or missing components of the URL.
- If springBoot version is below 2.7.0 then set server.contextPath=/bookstore.
- sometimes server.contextPath does not support springBoot version below 2.7.0 so use
server.servlet.context-path=/bookstore - Ensure that when deploy Spring Boot application to a servlet container, the servlet container uses ServletInitializer which extends SpringBootServletInitializer class to configure the application context.
public class ServletInitializer extends SpringBootServletInitializer {@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(BookStoreApplication.class);
}
} - Verify that the application which is trying to access the resource, has the necessary permissions.
