使用hibernate创建表测试无错误，但是无相应的表创建，求解惑

Question

如下是hibernate.cfg.xml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>
    <property name="connection.username">root</property>
    <property name="connection.password">123456</property>
    <property name="connection.driver_class">
        com.mysql.jdbc.Driver
    </property>
    <property name="connection.url">
        jdbc:mysql://localhost:3306/itheima_hibernate
    </property>
    <property name="dialect">
        org.hibernate.dialect.MySQLDialect
    </property>
    <property name="hbm2dd1.auto">update</property>
    <property name="show_sql">true</property>
    <mapping resource="simple/Student.hbm.xml" />
    <mapping resource="simple/Team.hbm.xml" />
</session-factory>
</hibernate-configuration>

如下是创建的Team.class

 package simple;

import java.io.Serializable;
import java.util.Set;

public class Team implements Serializable {
    private Long tid;
    private String name;
    private String description;
    private Set<Student> students;

    public Set<Student> getStudents() {
        return students;
    }
    public void setStudents(Set<Student> students) {
        this.students = students;
    }
    public Long getTid() {
        return tid;
    }
    public void setTid(Long tid) {
        this.tid = tid;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getDescription() {
        return description;
    }
    public void setDescription(String description) {
        this.description = description;
    }

}

配置文件Team.hbm.xml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="simple.Team">
        <id name="tid" length="5">
            <generator class="increment"></generator>
        </id>
        <property name="name" length="20"></property>
        <property name="description" length="50"></property>
        <set name="students">
            <!-- 外键 -->
            <key>
                <column name="tid"></column>
            </key>
            <one-to-many class="simple.Student"/>
        </set>
    </class>
</hibernate-mapping>

如下是Student.class

 package simple;

import java.io.Serializable;

public class Student implements Serializable {
    private Long sid;
    private String name;
    private String description;
    public Long getSid() {
        return sid;
    }
    public void setSid(Long sid) {
        this.sid = sid;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getDescription() {
        return description;
    }
    public void setDescription(String description) {
        this.description = description;
    }

}

student的配置文件Student.hbm.xml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="simple.Student">
        <id name="sid" length="5">
            <generator class="increment"></generator>
        </id>
        <property name="name" length="20"></property>
        <property name="description" length="50"></property>
    </class>
</hibernate-mapping>
