Question

我是Spring + Hibernate的新手，但我已经解决了这个问题。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，请提前感谢你。

这是一个问题，我只是编写一个简单的测试类，但是当我运行时，有一个例外：

??：在上下文初始化期间遇到异常 - 取消刷新＆gt;尝试：org.springframework.beans.factory.BeanCreationException：错误＆gt;创建名为'sessionFactory'的bean在类路径资源中定义＆gt;＆gt;＆gt;＆gt; ;＆gt;＆gt;＆gt; [ApplicationContext.xml]：调用init方法失败;嵌套异常是＆gt; org.hibernate.InvalidMappingException：无法读取XML 线程“main”中的异常＆gt; org.springframework.beans.factory.BeanCreationException：在类路径资源中定义了名称为'sessionFactory'的bean＆gt;时出错＆gt; [ApplicationContext.xml]：init方法的调用失败;嵌套异常是＆gt; 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） at 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） at org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons（DefaultListableBeanFactory.java:753） at 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(){
    }
    }

这是Employee.hbm.xml

  <?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-mapping package="com.domain">
   <class name="Employee" table="employee">
        <id name="id" type="java.lang.Integer">
            <generator class="native" ></generator> 
        </id>

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

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

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

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


   </class>
</hibernate-mapping>

这是ApplicationContext.cfg.xml

            hibernate.dialect=org.hibernate.dialect.OracleDialect

        </value>
    </property>
</bean>

</beans>

这是smiple测试类的源代码：

/**

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;

/**
 * @author Administrator
 *
 */
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！

Answer 1

应该在sessionFactory Bean中声明属性如下所示。

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

所以你的sessionFactory bean就像下面一样。

<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>

Answer 2

有时可能无法选择您的配置文件，因为编译器不知道配置时需要使用哪个文件。因此，出于这个原因，您应该通过2种方法显式导入那些配置文件，如我所知 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>

希望它将解决您的问题

Spring + Hibernate，无法读取xml错误
