Esempio di configurazione di integrazione di springmvc mybatis

La bellezza della semplicità, springmvc, mybatis rappresenta una buona soluzione di integrazione semplice, in grado di soddisfare le esigenze di un progetto comune. Durante il tempo libero, condivido il file di configurazione del progetto per consentire a tutti di guardarlo:

1. Prima di tutto, diamo un'occhiata alla dipendenza del file pom:
