hibernate不能自动创建表

[liuzhi1994]

hibernate不能将实体类在mysql中生产相对应的表
配置：

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
		<property name="url"
			value="jdbc:mysql://localhost/fc"></property>
		<property name="username" value="root"></property>
		<property name="password" value="sa"></property>
		<property name="maxActive" value="5"></property>
		<property name="maxIdle" value="2"></property>
	</bean>
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQL5Dialect
				</prop>
				<prop key="hibernate.hbm2ddl.auto">create</prop>
				<prop key="hibernate.show_sql">true</prop>
			</props>
		</property>
		<property name="packagesToScan">
			<list>
				<value>fc.po.*</value>
			</list>
		</property>
	</bean>

实体类的超类

@SuppressWarnings("serial")
@MappedSuperclass
public abstract class PoAbs implements Serializable{
	private String dataId;
	private String createTime;
	private String creater;
	private String updateTime;
	private String updater;
	@Id
	@Column(name = "data_id")
	@GeneratedValue(generator = "system-uuid")
	@GenericGenerator(name = "system-uuid", strategy = "uuid")
	public String getDataId() {
		return dataId;
	}
	public void setDataId(String dataId) {
		this.dataId = dataId;
	}
	public String getCreateTime() {
		return createTime;
	}
	public void setCreateTime(String createTime) {
		this.createTime = createTime;
	}
	public String getCreater() {
		return creater;
	}
	public void setCreater(String creater) {
		this.creater = creater;
	}
	
	
	public String getUpdateTime() {
		return updateTime;
	}
	public void setUpdateTime(String updateTime) {
		this.updateTime = updateTime;
	}
	public String getUpdater() {
		return updater;
	}
	public void setUpdater(String updater) {
		this.updater = updater;
	}
	
}

实体类：

@Entity
@Table(name="community")

public class Community extends PoAbs { 
	private String communtiyName;
	private String address;
	private District district;
	
	public String getCommuntiyName() {
		return communtiyName;
	}
	public void setCommuntiyName(String communtiyName) {
		this.communtiyName = communtiyName;
	}
	public String getAddress() {
		return address;
	}
	public void setAddress(String address) {
		this.address = address;
	}
	@ManyToOne(fetch=FetchType.LAZY)
	public District getDistrict() {
		return district;
	}
	public void setDistrict(District district) {
		this.district = district;
	}
	
}

补充一下 实体类Community是在fc.po包下

实体类里面忘记写hibernate创建类的数据库的类型了

[gnahshining]

<bean id="mySessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="hibernateProperties">
<props>
<!-- <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> -->
<prop key="hibernate.dialect">
org.hibernate.dialect.Oracle9Dialect
</prop>
<!-- 创建数据库
<prop key="hibernate.hbm2ddl.auto">create</prop>
-->
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
<!-- ===============================hibernate映射文件======================================= -->

<property name="mappingDirectoryLocations">
<list>
<value>classpath:/com/shining/po/hbm</value>
</list>
</property>
</bean>

实体类里还要指定数据库类型 怎么指定？不是在spring的配置文件里已经指定数据库类型来了吗

[liuzhi1994]

我用全注解方式的 不需要hbm文件映射的

[liuzhi1994]

怎么没高手来啊

[it-er]

console控制台没有报任何错误吗？

[fhqiu13647166580]

HIBERNATE好像没有自动去创建表吧,需要你自己去写一个工具类,将这些对象导入到数据库中去的呢?


//读取hibernate.cfg.xml文件
Configuration cfg = new Configuration().configure();

SchemaExport export = new SchemaExport(cfg);

export.create(true, true);

[liuzhi1994]

郁闷的就是没有报任何错

[liuzhi1994]

怎么没人知道啊

[/Quote]

你的实体类并没有注解你的字段类型呀

@Temporal(TemporalType.TIMESTAMP)
@Column(name="UPDATE_DATE", length=11)
public Date getUpdateDate() {
return this.updateDate;
}

@Column(name="WL_MOBILE", length=11)
public String getWlMobile() {
return this.wlMobile;
}

哈哈 问题找到了 问题自己找到100分还得给自己

[liuzhi1994]

我就一直怀疑是那些实体类没有被扫描到 结果 我把
<property name="packagesToScan">
<list>
<value>fc.po.*</value>
</list>
</property>
改成
<property name="packagesToScan">
<list>
<value>fc.*</value>
</list>
</property>
就生成出来了 原来packagesToScan是扫描*前面的一个包的所有子包里面的实体类 而我po包下已经没有包了直接是实体类 所以没被扫描到
