SPRINGMVC Consolidation controller Instantiation two issues

When starting the project, it was discovered that the initialization of the control layer was initiated two times by the way the construction method was used to print the log.

Later check the configuration:

<base-package= "Com.winning.joiner">        </  Context:component-scan>

found that when the configuration scan, there is no elimination of @controller layer Filter

After the modification, the problem is resolved as follows:

    <base-package= "Com.winning.joiner">         <  type = "Annotation" expression = "Org.springframework.stereotype.Controller"  />    </ Context:component-scan >
