Question

我真的需要你的帮助。

我是新的休眠。试图保存一个对象，但所有时间我都收到错误：

引起：com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException：表'hibernate.person'不存在

这是域对象：

@Table(name = "Person")
@Entity
public class Person {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private String id;
    @Column(name = "Person_age")
    private int age;
    @Column(name = "Person_name")
    private String name;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

这是我的hibernate配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!-- Database connection settings -->
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property>
        <property name="connection.username">root</property>
        <property name="connection.password">******</property>
        <property name="connection.pool_size">1</property>
        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Show all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">create</property>

        <!-- Mapping files -->
        <mapping class="ua.macko.domain.Person" />

    </session-factory>
</hibernate-configuration>

我得到的错误是：com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'hibernate.person' doesn't exist。

我试图设置hbm2ddl.auto参数来创建和更新，但这没有给我任何结果。

请告诉我，我做错了什么？

Thnx提前

添加javassist库后问题已解决。感谢大家的帮助！

Answer 2

<property name="hbm2ddl.auto">create</property>

hibernate.cfg.xml错误，请使用

<property name="hibernate.hbm2ddl.auto">create</property>

代替。

Hibernate Table不存在错误
