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

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.*" />
