【问题描述】：

我是 Spring + Hibernate 的新手，但我最近一天一直在解决这个问题。我仍然无法弄清楚根本原因是什么，我该怎么办。所以，如果有人能给我一些建议，请提前谢谢你。

这里有个问题，我只是写了一个简单的测试类，但是跑的时候出现异常：

??：上下文初始化期间遇到异常-取消刷新>尝试：org.springframework.beans.factory.BeanCreationException：错误>在类路径资源中创建名称为'sessionFactory'的bean >>>>>> [ApplicationContext .xml]：调用init方法失败；嵌套异常是 >org.hibernate.InvalidMappingException：无法读取 XML 线程“主”>org.springframework.beans.factory.BeanCreationException 中的异常：创建 bean 时出错>在类路径资源中定义名称为“sessionFactory”> [ApplicationContext.xml]：调用 init 方法失败；嵌套异常是> org.hibernate.InvalidMappingException：无法读取 XML 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1578) 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:545) 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:482) 在 org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:306) 在 org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:230) 在 org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:302) 在 org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:197) 在 org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:753) 在 org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:839) 在 org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:538) 在 org.springframework.context.support.ClassPathXmlApplicationContext.(ClassPathXmlApplicationContext.java:139) 在 org.springframework.context.support.ClassPathXmlApplicationContext.(ClassPathXmlApplicationContext.java:83) 在 com.xw.test.Test.main(Test.java:30)

这里是类源代码：

package com.domain;

import java.util.Date;

public class Employee {

    private Integer id;

    private String name;
    private String email;
    private java.util.Date hiredate;
    private Float salary;

    public Float getSalary() {
        return salary;
    }
    public void setSalary(Float salary) {
        this.salary = salary;
    }
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public java.util.Date getHiredate() {
        return hiredate;
    }
    public void setHiredate(java.util.Date hiredate) {
        this.hiredate = hiredate;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }

    public Employee( String name, String email, Date hiredate,
            Float salary) {
        this.name = name;
        this.email = email;
        this.hiredate = hiredate;
        this.salary = salary;
    }

    public Employee(){
    }
    }

这里是 Employee.hbm.xml

  <?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

        </id>

   <property name="email" type="java.lang.String" >
        <column name="email" length="64"/>
   </property>

   <property name="hiredate" type="java.util.Date">

   </property>

   <property name="salary" type="java.lang.Float">

   </class>
</hibernate-mapping>

这里是 ApplicationContext.cfg.xml

这里是smiple测试类源代码：

/**

package com.xw.test;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.domain.Employee;

/**

public class Test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        ApplicationContext ac = new ClassPathXmlApplicationContext("ApplicationContext.xml");

        SessionFactory sf = (SessionFactory) ac.getBean("sessionFactory");
        Session s = sf.openSession();

        Employee employee = new Employee( "aa", "aa.sohu@com", new java.util.Date(),
                (float) 234.56) ;
        Transaction tx = s.beginTransaction();
        s.save(employee);
        tx.commit();


    }

}

非常感谢您的任何建议！

【解决方案1】：

属性应该在你的 sessionFactory Bean 中声明如下。

           <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
           </props>

所以你的 sessionFactory bean 将如下所示。

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
    <list>
        <value>com/domain/Employee.hbm.xml</value>
    </list>
</property>
<property name="hibernateProperties">
           <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
           </props>
</property>

【讨论】：

嗨，Deendayal Garg 先生。非常感谢你的帮助。我已经根据您的建议进行了修改。但期待是一样的。顺便问一下，你有没有可能告诉我我应该检查哪本手册。我正在尝试查找官方手册来比较我是否错过或误解了某些内容，但我无法确定我应该选择哪个版本。我为此感到抱歉。并向您致以最良好的祝愿！

【解决方案2】：

有时可能无法选择您的配置文件，因为编译器不知道应该使用哪个文件进行配置。因此，您应该通过 2 种方法显式导入这些配置文件，因为我知道 1）通过使用类

@Configuration
@ImportResource(value = {"classpath:{filename-within-resource}/Employee.hbm.xml"},"classpath:{filename-within-resource}/ApplicationContext.cfg.xml")

public class CommonSolutionConfig {

}

2)通过使用xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns="http://www.springframework.org/schema/beans"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
    <import resource="classpath:{filename-within-resource}/Employee.hbm.xml"/>
    <import resource="classpath:{filename-within-resource}/ApplicationContext.cfg.xml"/>
</beans>

希望它能解决你的问题
