Difference between Java bean and spring bean.

JavaBeans are Java classes which adhere to certain coding conventions. Java bean classes will,

  • have public default (no argument) constructors,
  • have accessor (getter and setter) methods.
  • implement java.io.Serializable.

Spring bean is basically an object managed by Spring. It is an object that is instantiated, configured and managed by a Spring Framework container. Spring beans are defined in Spring configuration files.
