hibernate配置

hibernate配置

首先，建立实体类

package com.jimmyqin.bean;import java.sql.Date;public class UserBean {    private Integer id;    private String userName;    private String sex;    private Date birthday;    public UserBean() {    }    public UserBean(Integer id, String userName, String sex, Date birthday) {        super();        this.id = id;        this.userName = userName;        this.sex = sex;        this.birthday = birthday;    }    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    public String getUserName() {        return userName;    }    public void setUserName(String userName) {        this.userName = userName;    }    public String getSex() {        return sex;    }    public void setSex(String sex) {        this.sex = sex;    }    public Date getBirthday() {        return birthday;    }    public void setBirthday(Date birthday) {        this.birthday = birthday;    }}

然后建立实体类的映射文件UserBean.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"><hibernate-mapping>    <class name="com.jimmyqin.bean.UserBean" table="user" catalog="test">        <id name="id" type="java.lang.Integer">            <column name="id" />        </id>        <property name="userName" type="java.lang.String">            <column name="userName" length="10" not-null="true"  />        </property>        <property name="sex" type="java.lang.String">            <column name="sex" length="2" />        </property>        <property name="birthday" type="java.util.Date">            <column name="birthday" length="10" />        </property>    </class></hibernate-mapping>

使用maven添加jar包依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.jimmyqin</groupId>  <artifactId>newssh</artifactId>  <packaging>war</packaging>  <version>0.0.1-SNAPSHOT</version>  <name>newssh Maven Webapp</name>  <url>http://maven.apache.org</url>  <dependencies>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>3.8.1</version>      <scope>test</scope>    </dependency>    <!-- 添加Hibernate依赖 -->        <dependency>        <groupId>org.hibernate</groupId>        <artifactId>hibernate-core</artifactId>        <version>3.6.10.Final</version>      </dependency>      <!-- 添加Log4J依赖 -->        <dependency>        <groupId>log4j</groupId>        <artifactId>log4j</artifactId>        <version>1.2.16</version>      </dependency>      <dependency>         <groupId>org.slf4j</groupId>         <artifactId>slf4j-nop</artifactId>         <version>1.6.4</version>      </dependency>      <!-- 添加javassist -->        <dependency>         <groupId>javassist</groupId>         <artifactId>javassist</artifactId>          <version>3.12.0.GA</version>       </dependency>      <!-- mysql数据库的驱动包 -->      <dependency>          <groupId>mysql</groupId>          <artifactId>mysql-connector-java</artifactId>          <version>5.1.6</version>      </dependency>    </dependencies>  <build>    <finalName>newssh</finalName>    <plugins>              <plugin>                  <groupId>org.apache.maven.plugins</groupId>                  <artifactId>maven-compiler-plugin</artifactId>                  <version>3.1</version>                  <configuration>                      <source>1.8</source>                      <target>1.8</target>                  </configuration>              </plugin>          </plugins>    </build></project>

添加bibernate配置文件hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?>  <!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>          <!-- Database connection settings -->          <property name="connection.driver_class">com.mysql.jdbc.Driver</property>          <property name="connection.url">jdbc:mysql://localhost:3306/test</property>          <property name="connection.username">root</property>          <property name="connection.password">root</property>          <!-- JDBC connection pool (use the built-in) -->          <property name="connection.pool_size">1</property>          <!-- SQL dialect -->          <property name="dialect">org.hibernate.dialect.MySQLDialect</property>          <!-- Enable Hibernate's automatic session context management -->          <property name="current_session_context_class">thread</property>          <!-- Disable the second-level cache  -->          <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>          <!-- Echo all executed SQL to stdout -->          <property name="show_sql">true</property>          <property name="format_sql">true</property>          <!-- Drop and re-create the database schema on startup -->          <property name="hbm2ddl.auto">update</property>          <mapping resource="com/jimmyqin/bean/UserBean.xml"/>      </session-factory>  </hibernate-configuration>
