控制台显示是sessionFactory的init方法（即初始化）失效，于是我很自然的去找ApplicationContex.xml文件中sessionFactory的配置段，可是检查了一段下来之后并没有发现什么不妥，紧接着看到下面一行 Could not parse mapping document from input stream，想着是不是映射文件出了问题？查到映射文件，发现<id>标签上name属性没有配置，所以导致了实体类中的属性和数据库中对应的表格字段不符，因此抛出了异常信息。

结论：数据库表字段和实体类属性不一致时会产生该异常（org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource \[applicationContext.xml\]: Invocation of init method failed; nested exception is org.hibernate.InvalidMappingException: Could not parse mapping document from input stream）

正确的是 <id name="id" type="int">  
<column name="id" />  
<generator class="identity" />  
</id>
