SpringMVC 4 + Hibernate4的Entity自动扫描配置问题？配置报错

基础描述J2ee 7，IDE：IDEA13.1，SpringMVC 4.0.4.RELEASE Hibernate 4.3.5.Final
我想重新建立自动化框架，以前通过springmvc3+hibernate3 自动扫描@Controller自动扫描和@Entity自动建表
现在迁移到了Spring4 与hibernate4 但是Entity就是不创建
配置如下
web.xml

偶然翻进来这个问题，题主是没有理解那个配置的意思，packagesToScan表示配置你需要sping帮你扫描的包名，也就是只需要详细到包，而题主在配置的时候写的是com.springapp.mvc.entity.*表示的就是entity包下的所有包，而你的entity里面只有详细的类，所以第一次扫描不到包。第二次配置为com.springapp.mvc.就是表示扫描mvc下的所有包，mvc下至少有个entity包，所以可以生效。
其实题主只需要把配置写成com.springapp.mvc.entity就行了。加上“.”就是画蛇添足。 ######人工置顶=。=###### 自己搞定，需要把mvc.conf.xml里面的

<property name="packagesToScan" value="com.springapp.mvc.entity.*" />

修改成为

<property name="packagesToScan" value="com.springapp.mvc.*" />

必须在扫描Entity的上一级 =。=
