两个实体类
package vo;
public class message {
private int mid;
private String mname;
private int age;
private String mail;
private String address;
private String tel;
private User user;
public int getMid() {
return mid;
}
public void setMid(int mid) {
this.mid = mid;
}
public String getMname() {
return mname;
}
public void setMname(String mname) {
this.mname = mname;
}
@Override
public String toString() {
return "message [mid=" + mid + ", mname=" + mname + ", age=" + age
+ ", mail=" + mail + ", address=" + address + ", tel=" + tel
+ ", user=" + user + "]";
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getMail() {
return mail;
}
public void setMail(String mail) {
this.mail = mail;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
第二个user实体类
package vo;
public class User {
private Integer id;
private message m;
public message getM() {
return m;
}
public void setM(message m) {
this.m = m;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
private String name;
private String pwd;
}
hibernate配置
<?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="vo.message" table="message">//name：实体的路径，table：对应表的名字
<id name="mid" column="mid">//id为主键 name为实体中的属性 column为表中的列名
<generator class="native"></generator>
</id>
<property name="mname" column="mname"></property>//非主键
<property name="age" column="age"></property>
<property name="mail" column="mail"></property>
<property name="address" column="address"></property>
<property name="tel" column="tel"></property>
<one-to-one name="user" constrained="true" cascade="all"></one-to-one>//表示一对一对应 cascade为级联关系
</class>
</hibernate-mapping>
以下为user表对应的数据配置：
将项目部署在tomcat服务器上就可以自动生成表。
