【问题描述】：

我正在尝试在 Eclipse IDE 中使用休眠，我已经成功地对 POJO 类进行了逆向工程。但是它显示会话工厂下的hibernate配置错误。

hibernate.cfg.xml

<?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>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.password">1234</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost/customer</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>


    <mapping class="com.example.pojo.Customer"/>
    <mapping resource="com/example/pojo/Customer.hbm.xml"/>
</session-factory>
</hibernate-configuration>

hibernate.reveng.xml

<?xml version="1.0" encoding="UTF-8"?>

 <hibernate-reverse-engineering>
<table-filter match-catalog="customer" match-name="customer" />
<table catalog="customer" name="customer">
    <column name="id"></column>
    <column name="firstName"></column>
    <column name="cuscol"></column>
    <column name="lastName"></column>
    <column name="birthDate"></column>
    <column name="email"></column>
</table>
</hibernate-reverse-engineering>

public class Customer implements java.io.Serializable 

private int id;
private String firstName;
private String cuscol;
private String lastName;
private Date birthDate;
private String email;

public Customer() 


public Customer(int id) 
    this.id = id;


public Customer(int id, String firstName, String cuscol, String lastName, Date birthDate, String email) 
    this.id = id;
    this.firstName = firstName;
    this.cuscol = cuscol;
    this.lastName = lastName;
    this.birthDate = birthDate;
    this.email = email;


public int getId() 
    return this.id;


public void setId(int id) 
    this.id = id;


public String getFirstName() 
    return this.firstName;


public void setFirstName(String firstName) 
    this.firstName = firstName;


public String getCuscol() 
    return this.cuscol;


public void setCuscol(String cuscol) 
    this.cuscol = cuscol;


public String getLastName() 
    return this.lastName;


public void setLastName(String lastName) 
    this.lastName = lastName;


public Date getBirthDate() 
    return this.birthDate;


public void setBirthDate(Date birthDate) 
    this.birthDate = birthDate;


public String getEmail() 
    return this.email;


public void setEmail(String email) 
    this.email = email;

【问题讨论】：

哎呀它在那里..sory

映射资源和映射类是否需要同时存在于同一个 Pojo 中？它可能不会抛出错误..但看起来不合适

【参考方案1】：

像这样更新 customer.hbm.xml 中的映射条目 -

<class="com.example.pojo.Customer" table= "customer"/>

【讨论】：

属性“table”无效
