Spring Boot从1.4.4RELEASE升级到1.5.12RELEASE加载上下文报错求助

Hey, I’ve dealt with this exact problem during a Spring Boot version upgrade—let’s get this sorted out for you.

What’s Causing the Error? #

Spring Boot 1.5.x reorganized web-related classes to align with modern Servlet standards. The ServletRegistrationBean class (along with similar ones like FilterRegistrationBean and ServletListenerRegistrationBean) was moved from:

org.springframework.boot.context.embedded

to:

org.springframework.boot.web.servlet

Your code is still referencing the old package path, which no longer exists in Spring Boot 1.5.12.RELEASE—hence the ClassNotFoundException.

Step-by-Step Fix #

• Update import statements: Go through all your Java files and replace any imports pointing to org.springframework.boot.context.embedded.ServletRegistrationBean with org.springframework.boot.web.servlet.ServletRegistrationBean. Don’t forget to check for related classes like FilterRegistrationBean if you use them—they moved to the same new package too.
• Check XML configurations (if applicable): If you define beans in XML, update the full class name from org.springframework.boot.context.embedded.ServletRegistrationBean to the new package path.
• Clean and rebuild your project: Old class files or cached dependencies might still be lingering. Run:
  • For Maven: mvn clean install
  • For Gradle: ./gradlew clean build

That should resolve the class-not-found error and let your application context load properly.
