java.lang.NullPointerException
com.exemplecrud.bean.CustomerBean.init(CustomerBean.java:27)

Ca me semble clair, ton code déclenche un NullPointerException dans la méthode init, ligne 27 du CustomerBean.java, qui viens du fait que customerService est null. Tu as probablement du oublié d'injecter cette valeur quelque part dans ta config.

**patouche** · 10/01/2014, 01h11

Entièrement d'accord avec tchize_ ... L'erreur est très clair.

Ton injection de bean, tu la fais comment ?

Tu sembles utiliser les annotations ?

@Autowired ?

Cordialement,
