SpringHibernate，无法读取xml错误

Question

我是Spring冬眠的新手，但我已经花了一天时间解决这个问题。我还是搞不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，提前谢谢你。

这里有一个问题，我只是写一个简单的测试类，但是当我运行时，有一个例外：

??: 上下文初始化期间遇到异常-取消刷新

这里是类的源代码：

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(){
    }
    }

这是员工。哈佛商学院。xml

下面是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();


    }

}

非常感谢你的任何建议！

Answer 1

有时，由于编译器不知道应该使用哪个文件进行配置，所以可能无法选择您的配置文件。所以，出于这个原因，你应该通过2种方法显式导入这些配置文件，我知道1）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

Answer 2

属性应该在sessionFactory Bean中声明，如下所示。

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

因此，您的会话工厂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>
