Hibernate Annotations

Jcreek

不好意思又要请教各位了。使用Hibernate Annotations配置如下:
applicationContext.xml
    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource">
                <ref local="dataSource"/>
        </property>
                <property name="annotatedClasses">
                    <list>
                        <value>com.spider.domain.Suburb</value>
                    </list>
                </property>                       
        <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">net.sf.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
        </property>
    </bean>

    <bean id="suburbDAO" class="com.spider.dao.SuburbDAOImpl">
        <property name="sessionFactory"><ref local="sessionFactory"/></property>
    </bean>

Suburb.java
package com.spider.domain;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="SUBURB")
public class Suburb {
        private Long id;
        private String name;
        private String postcode;
        private String state;
       
        @Id
        @Column(name="ID")
        public Long getId() {
                return id;
        }
        public void setId(Long id) {
                this.id = id;
        }
       
        @Column(name="NAME")
        public String getName() {
                return name;
        }
        public void setName(String name) {
                this.name = name;
        }
        @Column(name="POSTCODE")
        public String getPostcode() {
                return postcode;
        }
        public void setPostcode(String postcode) {
                this.postcode = postcode;
        }
        @Column(name="STATE")
        public String getState() {
                return state;
        }
        public void setState(String state) {
                this.state = state;
        }
}

以上是彻底参照http://www.vaannila.com/spring/s ... -integration-1.html里面的例子。
现在搞不懂是sessionFactory的问题还是我自己的class的问题。

悲剧。

昨天不是告诉你改 .xml 改build action 属性吗。

干吗又要换Annotations?

Jcreek

是呀，昨天的没问题了。想改成Annotations试试，结果弄不通了。

dalaohu

哦，这样啊。 那你自己慢慢玩吧 :)

Maybe jar files conflict, not sure

Jcreek

使用hibernate annotation工作了。有谁知道上面和这个之间的差异?

90％的可能是jar classpath冲突。。。

东北老乡

19/11/2010 16:04:01 org.hibernate.cfg.Environment <clinit>
INFO: Hibernate 3.0.5

应该是jar conflict. 跟config没关系吧. 为什么会是Hibernate 3.0.5

starchu

查查自己的classpath的hibernate annotation相关的jar,

东北老乡

只有Hibernate 3.1 以上才有org/hibernate/context/CurrentSessionContext Class
Hibernate 版本太低了

如果你用maven的话，可以很容易查看项目的jar dependencies的情况，如果你没有maven, 那就只好自己手动排查了

starchu

估计你提供的hibernate版本和你的spring版本所需要的hibernate版本不一致，导致spring不能inject sessionFactory

Jcreek

wow. thanks guys. learned that

Jcreek

五湖！Bean + Annotations 工作了！果然是Hibernate jar的问题，选了太低的版本。
谢谢各位高手！准备安装Maven.
