hibernate + spring + springmvc + maven （hibernate自动建表功能）

1.新建maven项目：

2.导入相关依赖的jar包

<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">

    <build>

</project>

3.编辑web.xml文件

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
    <display-name>Archetype Created Web Application</display-name>

    <!--spring-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext2.xml</param-value>
    </context-param>

    <!--spring listener-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--spring mvc-->
    <servlet>
        <servlet-name>springMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!-- 此处指向的的是SpringMVC的配置文件 -->
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <!--配置容器在启动的时候就加载这个servlet并实例化-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springMVC</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

4.新建页面：index.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
    <a href="../index">点我</a>
</body>
</html>

5.新建后台controllor

package com.xuzhiwen.controllor;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class IndexController {
    
    @RequestMapping(value="/index")
    public String index(Model model,HttpServletRequest request,HttpServletResponse response){
        System.out.println("index...");
        return "index";
    }
}

6.新建

applicationContext1.xml

applicationContext2.xml

spring-mvc.xml

内容如下：

spring-mvc.xml

        </property>
    </bean>
</beans>

7.运行项目，进入index.html

点击链接结果如下：

说明: spring + springmvc 搭建成功。

7.新建配置文件:

config.properties

database.properties

druid.properties

hibernate.properties

8.新建实体类：

AA01.java

package com.xuzhiwen.entity;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

import org.hibernate.annotations.GenericGenerator;


@Entity
@Table(name="AA01")
public class AA01 {
    @Id
    @GeneratedValue(generator="system-uuid")  
    @GenericGenerator(name="system-uuid", strategy = "uuid.hex")  
    private String id;
    
    @Column(name = "AAA001", length = 30)
    private String AAA001;
    
    @Column(name = "AAA002", length = 30)
    private String AAA002;
    
    @Column(name = "AAA003", length = 30)
    private String AAA003;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getAAA001() {
        return AAA001;
    }

    public void setAAA001(String aAA001) {
        AAA001 = aAA001;
    }

    public String getAAA002() {
        return AAA002;
    }

    public void setAAA002(String aAA002) {
        AAA002 = aAA002;
    }

    public String getAAA003() {
        return AAA003;
    }

    public void setAAA003(String aAA003) {
        AAA003 = aAA003;
    }
}

注意：红色字体为生成主键的方式，缺少的话，能运行成功，但无法创建表

9.运行项目，结果如下：

 这样，表就自动生成了

10. 添加事务，配置如下：

<!-- 配置事务容器 -->
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
        <property name="dataSource" ref="dataSource" />
    </bean>
    
    <!-- 定义事务规则 -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="insert*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="edit*" propagation="REQUIRED" />
            <tx:method name="delete*" propagation="REQUIRED" />
            <tx:method name="del*" propagation="REQUIRED" />

            <tx:method name="clear*" propagation="REQUIRED" />
            <tx:method name="init*" propagation="REQUIRED" />
            <tx:method name="run*" propagation="REQUIRED" />
        </tx:attributes>
    </tx:advice>

    <!-- 定义事务入口 -->
    <aop:config>
        <aop:pointcut id="txPointcut" expression="execution(* com.xuzhiwen.dao.*.*(..))" />
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut" />
    </aop:config>

且web.xml里面需添加代码：

　　<filter>
        <filter-name>SpringOpenSessionInViewFilter</filter-name>
        <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>SpringOpenSessionInViewFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

这样才能保证不报错
