第八周学习总结

1.学习了hibernate框架

2.学习了TensorFlow的验证码识别，通过opencv生成图片

1.hibernate架构：

Student.java

package com.example;


public class Student {
    private String ID;
    private String Name;

    public Student(){}
    public String getName() {
        return Name;
    }

    public void setName(String name) {
        Name = name;
    }

    public String getID() {
        return ID;
    }

    public void setID(String ID) {
        this.ID = ID;
    }
}

Student.hbm.xml

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

    <class name="com.example.Student" table="student">

        </id>
        <property name="Name" type="java.lang.String">
            <column name="Name"></column>
        </property>

    </class>
</hibernate-mapping>

hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD//EN"

        <!-- DB schema will be updated if needed -->

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

Test.java

package test;

    public static void  main(String [] args)

        Session session=sessionFactory.openSession();
        Transaction transaction=session.beginTransaction();
        Student student=new Student();
        student.setID("216");
        student.setName("liu");
        session.save(student);
        transaction.commit();
        session.close();
        System.out.println("Successfule saved");
    }
}
