Spring+Hibernate+Struts2项目的数据配置不能映射
Spring配置文件如下：
- XML code
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/sciproject?useUnicode=true?amp;characterEncoding=UTF-8" /> <property name="username" value="root" /> <property name="password" value="root" /> <property name="initialPoolSize" value="1" /> <property name="minPoolSize" value="1" /> <property name="maxPoolSize" value="40" /> <property name="maxIdleTime" value="20" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="mappingResourses"> <list> <value>cn/itcast/vo/Teacher.hbm.xml</value> <value>cn/itcast/vo/Thesis.hbm.xml</value> <value>cn/itcast/vo/Research.hbm.xml</value> <value>cn/itcast/vo/Literary.hbm.xml</value> <value>cn/itcast/vo/Achievement.hbm.xml</value> </list> </property> </bean> <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean></beans>
对应的映射文件如下(只列出其中一个）：
Research.hbm.xml
- XML code
<?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> <class name="cn.itcast.vo.Research" table="sci_research"> <id name="researchId" type="java.lang.Integer" column="researchId" /> <property name="researchName" type="java.lang.String" column="researchName" /> <property name="rank" type="java.lang.String" column="rank" /> <property name="leader" type="java.lang.String" column="leader" /> <property name="leader_organization" type="java.lang.String" column="leader_organization" /> <property name="sLeader" type="java.lang.String" column="sLeader" /> <property name="sLeader_organization" type="java.lang.String" column="sLeader_organization" /> <property name="publishDate" type="java.util.Date" column="publishDate" /> <property name="expense" type="java.lang.String" column="expense" /> </class></hibernate-mapping>
由于文件已经被myeclipse fomular，所以不会有空格或空行问题，dom4j-1.6.1.jar包已经加入
但出现如下问题：
- C# code

请问该如何解决呢
[解决办法]
问题是说你的spring配置文件里面sessionfactory创建错误了
我没有这样创建过不知道你写的是不是对的 你好好看看别人的代码估计是你那个位子写错了
[解决办法]
- Java code
Content is not allowed in prolog. Nested exception: Content is not allowed in prolog

[解决办法]
映射文件问题。
仔细检查Research.hbm.xml文件中的name与实体bean是否对应。还有就是映射到数据库的字段最好不用驼峰写法。
<property name="leaderOrganization" type="java.lang.String" column="leader_organization" />
[解决办法]
这个就是xml文件的问题，，，lz自己好好检查下。。

hibernate配置文件有问题
仔细看看吧
你在单独使用hibernate的时候会不会有呢
