“创建名称为bean的错误”创建事务管理器时 [英] "Error creating bean with name" When creating a Transaction Manager

问题描述

这是我的hibernate.cfg.xml

 <？xml version =1.0encoding =UTF-8 >？; 
<！DOCTYPE hibernate-configuration PUBLIC 
 -  // Hibernate / Hibernate配置DTD 3.0 // EN
http://hibernate.sourceforge.net/hibernate-configuration-3.0 .dtd> 
 
< hibernate-configuration> 
< session-factory> 
 <！ - 数据库连接设置 - > 
< property name =connection.driver_class> com.mysql.jdbc.Driver< / property> 
< property name =connection.url> jdbc：mysql：// localhost：3306 / sometable< / property>

< mapping class =data.Person/>

这里是我的applicationContext.xml

我在这里错过了什么？

解决方案

这个论坛有一个解决方案：

在SO中也有重复：

Spring source suit e spring3 + Hibernate4 + maven 3 + MySQL 5

Here is my hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
