hibernate.cfg.xml配置

<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>

        <!--  <property name="hibernate.current_session_context_class">thread</property>-->
    </session-factory>
</hibernate-configuration>

User实体类hbm.xml配置

<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>

        <id name="id" type="java.lang.Integer">
            <column name="ID" />
            <generator class="native" />
        </id>
        <property name="username" type="java.lang.String">

            <column name="disabled" />
        </property>
    </class>
</hibernate-mapping>

注意事项

1.User实体类要有默认的无参构造方法,才能在Controller的从参数中传递User参考博客
2.SessionFactory通过注解自动构造

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }
    @Autowired
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
    private Session getCurrentSession() {
        return sessionFactory.getCurrentSession();
    }
