Question

spring 整合的hibernate，有实体类，映射文件，无法生成数据库表

spring中自动生成表的配置：
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.Oracle9Dialect
</prop>
<prop key="hbm2ddl.auto">create</prop>
<prop key="hibernate.show_sql">true</prop>

<!-- <prop key="current_session_context_class">Thread</prop> -->
</props>
</property>
实体类：

public class Admin implements java.io.Serializable {

// Fields

private Integer id;
private String username;
private String password;

// Constructors

/** default constructor */
public Admin() {
}

/** full constructor */
public Admin(Integer id, String username, String password) {
this.id = id;
this.username = username;
this.password = password;
}
setter、getter；
}
映射文件：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!--

-->
<hibernate-mapping>
<class name="com.bzu.entity.Admin" table="admin">
<id name="id" type="java.lang.Integer">
<column name="id" />
<generator class="native" />
</id>
<property name="username" type="java.lang.String">
<column name="username" length="20" not-null="true" />
</property>
<property name="password" type="java.lang.String">
<column name="password" length="20" not-null="true" />
</property>
</class>
</hibernate-mapping>

Answer 1

<class name="com.bzu.entity.Admin" table="t_admin">

映射文件:table 改成别的，如t_admin。

从你设置的方言，看出使用的是Oracle，admin是Oracle 关键字(保留字)

其他的关键字你也搜一下，以后回避掉。
