org.springframework.beans.factory.BeanCreationException: Error creating bean wit

Entity.hbm.xml文件dtd验证错误引起的问题

 

下午无事，自己动手使用ssh实现注册登录的小功能，结果出现让我纠结两小时的问题！贴出来大家共勉！！！

 

User.java实体类

 

package com.lr.pojo;

public class User {

	public int id;
	public String name;
	public String pwd;
	public char type;
	
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPwd() {
		return pwd;
	}
	public void setPwd(String pwd) {
		this.pwd = pwd;
	}
	public char getType() {
		return type;
	}
	public void setType(char type) {
		this.type = type;
	}
	
}

 

User.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
 <hibernate-mapping package="com.lr.pojo">
   <class name="User" table="test_user" >
      		<id name="id"  column="userid"  type="integer">
      				<generator class="native">
      				    <param name="sequence">tu_seq</param>
      				</generator>
      		</id>
      		<property name="name" type="string">
                <column name="username"/>
            </property>
      		<property name="pwd" type="string">
      		    <column name="userpwd"/>
       		</property>
      		<property name="type" type="character">
      		    <column name="usertype"/>
      		</property>
      </class>
</hibernate-mapping>

 UserDao.java

UserDaoImpl.java

applicationContext.xml

使用Junit测试整合效果

报如下错误：

反复查看觉得自己没有错误，甚至一度怀疑IDE的问题（⊙﹏⊙b汗）

各种的百度，google，终于正解出现了...

User.hbm.xml的dtd验证没写，就悲剧了。。。。。。。。

添加下面的
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

映射文件应该用hibernate-mapping-3.0.dtd

 

User.hbm.xml应如下：

<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" > 
<hibernate-mapping package="com.lr.pojo">
   <class name="User" table="test_user" >
      		<id name="id"  column="userid"  type="integer">
      				<generator class="native">
      				    <param name="sequence">tu_seq</param>
      				</generator>
      		</id>
      		<property name="name" type="string">
                <column name="username"/>
            </property>
      		<property name="pwd" type="string">
      		    <column name="userpwd"/>
       		</property>
      		<property name="type" type="character">
      		    <column name="usertype"/>
      		</property>
      </class>
</hibernate-mapping>

 

 

ok

问题解决！

 

一直以为这个类似于注释的东东，完全没有作用

今天它用长达两个小时的纠结与怀疑，狠狠的给我了一巴掌！！！

 

切记勿忘验证！！！！
