Build hibernate5.0 Environment under eclipse

1. Hibernate-introduced jar package: Hibernate-release-5.0.12.final.zip
2. Database driver: mysql-connector-java-5.1.46

Two. Install Hibernate plugin

Open Eclipse, click Help-->eclipse Marketplace, enter: Hibernate tools, then click the Goa button to find JBoss tools

Click Install installation

Select Hibernate Tools and click Confrm Installation. Restart Eclipse when the installation is complete.

Three. Create a project

1. Create a new project Hibernatedemo, set up the Lib folder under Project. Open the directory for the jar package, import the jar package under lib/required and the database, add to build path

Create a new file under SRC

Click Next, default file name, click Next, configure database information

Select UTF-8 encoding, click Finish, generate the Hibernate.cfg.xml configuration file content as follows

<?XML version= "1.0" encoding= "UTF-8"?><!DOCTYPE hibernate-configuration Public "-//hibernate/hibernate configuration DTD 3.0//en" "Http://www.hi Bernate.org/dtd/hibernate-configuration-3.0.dtd "><hibernate-configuration>    <session-factory>        < Propertyname= "Hibernate.connection.driver_class">Com.mysql.jdbc.Driver</ Property>        < Propertyname= "Hibernate.connection.password">A123</ Property>        < Propertyname= "Hibernate.connection.url">Jdbc:mysql://localhost:3306/tb_test</ Property>        < Propertyname= "Hibernate.connection.username">Sherman</ Property>        < Propertyname= "Hibernate.dialect">Org.hibernate.dialect.MySQLDialect</ Property>                    </session-factory></hibernate-configuration>

Note that the name attribute of <session-factory name= "MySQL"> is removed, Otherwise report org.hibernate.engine.jndi.JndiException exception, add some configuration in this file,

<?XML version= "1.0" encoding= "UTF-8"?><!DOCTYPE hibernate-configuration Public "-//hibernate/hibernate configuration DTD 3.0//en" "Http://www.h Ibernate.org/dtd/hibernate-configuration-3.0.dtd "><hibernate-configuration>    <session-factory>        < Propertyname= "Hibernate.connection.driver_class">Com.mysql.jdbc.Driver</ Property>        < Propertyname= "Hibernate.connection.password">A123</ Property>        < Propertyname= "Hibernate.connection.url">Jdbc:mysql://localhost:3306/tb_test</ Property>        < Propertyname= "Hibernate.connection.username">Sherman</ Property>                <!--Configure database dialect -        < Propertyname= "Hibernate.dialect">Org.hibernate.dialect.MySQL5Dialect</ Property>        <!--Console Print SQL statements -        < Propertyname= "Show_sql">True</ Property>        <!--Formatting SQL -        < Propertyname= "Format_sql">True</ Property>        <!--Update the database at startup based on configuration -        < Propertyname= "Hibernate.hbm2ddl.auto">Update</ Property>        <!--Configure connection Pool connection number -        < Propertyname= "Connection.pool_size">20</ Property>                <!--Registering Entity Mapping classes -        <Mappingclass= "Com.gdut.app.entity.News"/>    </session-factory></hibernate-configuration>

Create a new package com.gdut.app.entity under SRC, storing the Persistence class News,news class code as follows

 Packagecom.gdut.app.entity;Importjavax.persistence.Entity;ImportJavax.persistence.GeneratedValue;ImportJavax.persistence.GenerationType;Importjavax.persistence.Id;Importjavax.persistence.Table; @Entity @table (name= "News_info") Public classNews {@Id @generatedvalue (strategy=generationtype.identity)PrivateInteger ID;PrivateString title;PrivateString content; PublicNews () {} PublicNews (Integer ID, string title, string content) { This. ID =ID;  This. title =title;  This. Content =content;} PublicInteger getId () {returnID;} Public voidsetId (Integer id) { This. ID =ID;} PublicString GetTitle () {returntitle;} Public voidSettitle (String title) { This. title =title;} PublicString getcontent () {returncontent;} Public voidsetcontent (String content) { This. Content =content;} @Override PublicString toString () {return"News [id= + ID +", title= "+ title +", content= "+ content +"] ";}}

To write a test class:

 Packagecom.gdut.app.entity;Importorg.hibernate.Session;Importorg.hibernate.SessionFactory;Importorg.hibernate.Transaction;Importorg.hibernate.cfg.Configuration;Importorg.junit.Test; Public classbeantest {@Test Public voidbeantest () {//final Standardserviceregistry serviceregistry = new Standardserviceregistrybuilder ()//. Configure ("Hibernate.cfg.xml"). Build ();//        //sessionfactory SF = new Metadatasources (serviceregistry). Buildmetadata (). Buildsessionfactory (); //two ways to get sessionfactoryConfiguration cfg =NewConfiguration (). Configure (); Sessionfactory SF=cfg.buildsessionfactory (); Session Sess=sf.opensession (); Transaction Transaction=sess.begintransaction (); News N=NewNews (); N.setcontent ("Graduated from Guang Gong"); N.settitle ("Graduation Season");        Sess.save (n);        Transaction.commit ();            Sess.close (); }}

or through the mapping file

Under the Com.gdut.app.entity package resume a News.hbm.xml mapping configuration file, modify the class property of Genarator to Active

<?XML version= "1.0"?><!DOCTYPE hibernate-mapping Public "-//hibernate/hibernate mapping DTD 3.0//en" "http://hibernate.sourceforge.net/ Hibernate-mapping-3.0.dtd "><!--Generated 2018-5-22 23:45:23 by Hibernate Tools 3.5.0.Final -<hibernate-mapping>    <classname= "Com.gdut.app.entity.News"Table= "NEWS">        <IDname= "id"type= "Java.lang.Integer">            <columnname= "ID" />            <Generatorclass= "Native"/>        </ID>        < Propertyname= "title"type= "Java.lang.String">            <columnname= "TITLE" />        </ Property>        < Propertyname= "Content"type= "Java.lang.String">            <columnname= "CONTENT" />        </ Property>    </class></hibernate-mapping>
