三.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>MavenSSH</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  <!-- 配置Struts2过滤器 -->
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- 配置Spring的监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 指定Spring配置文件所在路径 -->

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring.xml</param-value>
    </context-param>
</web-app>

注意：将指定spring配置文件路径中<param-values>中的路径换成你的spring配置文件所在路径:spring配置文件名。
html

四.在项目的src/main/resource包下新建.properties文件

#mysql config
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=true
jdbc.user=/**数据库链接名**/
jdbc.password=/**链接密码**/

#hibernate config  
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.show_sql=true
hibernate.format_sql=false
hibernate.hbm2ddl.auto=update

 
 注意： 
 将.properties中数据库的链接名，链接密码换成你的链接名和链接密码。 

 
 同时mysql数据库驱动5版本如下(包括5)driver为*：com.mysql.jdbc.Driver; 

 
 6为com.mysql.Cj.jdbc.Driver 。 

五.配置spring.xml文件

(1)在src/main/resource包下新建spring.xml文件

(2)写入代码

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd">
        
    <!-- 引入properties -->
    <context:property-placeholder location="classpath:database.properties"/>
    <!-- 开启包扫描，并注册注解，扫描@Service,@Controller,@Repository,.... -->
    <!-- 在base-package后定义的包中扫描(这里是action，和lib包，两个包都在src/main/java包下) -->
    <context:component-scan base-package="action,lib"/>

    <!-- 配置数据源 -->
    <bean id="dataSource"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="${jdbc.driver}">
		</property>
		<property name="url" value="${jdbc.url}">
		</property>
		<property name="username" value="${jdbc.user}"></property>
		<property name="password" value="${jdbc.password}"></property>
	</bean>
    
    <!-- 配置hibernate sessionfactory -->
    <bean id="sessionFactory"
		class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">${hibernate.dialect}</prop>
				<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
				<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
			</props>
		</property>
		<property name="mappingResources">
			<list>
				<!-- <value>lib/Account.hbm.xml</value> -->
			</list>
		</property>
		<!-- Scan entities automatically 自动扫描实体类Entity,在value后的包中扫描(这里是lib包) -->
		<property name="packagesToScan" value="lib"/>
	</bean>
</beans>

六.在src/main/java/下新建一个包lib,里面存放:

表明数据库中一张表的实体类Entity
实现数据库操做的Dao接口（Dao层）
实现了Dao接口的Dao类（Dao层）
Service层：包含Dao类对象，经过调用Dao类对象方法对数据库进行操做。

(1)表的实体类:

表定义以下:

新建一个类Account.java做为这张表的实体类

写入如下代码：

注释请搜索： hibernate用注解配置实体类的映射

package lib;

import java.sql.Date;
import javax.persistence.*;

@Entity		//注意要加Entity注释
@Table(name="account", catalog="test") //schema="dbo"，name指定表名映射
public class Account {
	@Id //主键值(至少一个)
	@Column(name="accountName") //其中成员变量名与表中对应列名不一样要创建映射关系
	private String accountId;
	@Column(name="createDate")	
	private Date createDate;
	//@Column(name="balance"),成员变量名和表中列名相同能够省略注释
	private int balance;
	public String getAccountId() {
		return accountId;
	}
	public void setAccountId(String accountId) {
		this.accountId = accountId;
	}
	public Date getCreateDate() {
		return createDate;
	}
	public void setCreateDate(Date createDate) {
		this.createDate = createDate;
	}
	public int getBalance() {
		return balance;
	}
	public void setBalance(int balance) {
		this.balance = balance;
	}
}

（2）Dao层

接口（本例中为AccountDao.java）

package lib;

public interface AccountDao {
	void save(Account account);
	Account findById(String accountId);
}

接口的实现类（本例中为AccountDaoImpl.java

package lib;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate5.HibernateTemplate;
import org.springframework.stereotype.Repository;
/*
 * Account表-Dao实现
 * 
 * 
 */
@Repository
public class AccountDaoImpl implements AccountDao{
 private HibernateTemplate template;
 
 @Autowired
 public AccountDaoImpl(SessionFactory sessionFactory) {
  this.template = new HibernateTemplate(sessionFactory);
 }
 
 public void save(Account account) {
  template.save(account);
  //手动管理事务
  //Session s = sessionFactory.openSession();
  //Transaction tx = s.beginTransaction();
  //s.save(account);
  //tx.commit();
  //s.close();
 }
 @Override
 public Account findById(String accountId) {
  // TODO Auto-generated method stub
  return template.get(Account.class, accountId);
  //手动管理事务
  //return sessionFactory().openSession().find(Account.class,accountId);
 }
}

(3)Service层

接口（本例中为AccountService）

package lib;

public interface AccountService {
	void save(Account account);
	Account findById(String accountId);
}

Service接口的实现类（本例中为AccountServiceImpl，类中包含了Dao的实现类对象）

package lib;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class AccountServiceImpl implements AccountService {
	
	//Dao接口的上转型对象
	@Autowired
	private AccountDao accountDao;
	@Override
	public void save(Account account) {
		// TODO Auto-generated method stub
		accountDao.save(account);
	}

	@Override
	public Account findById(String accountId) {
		// TODO Auto-generated method stub
		return accountDao.findById(accountId);
	}

}

七.Action

1.在src/main/java/包下新建一个action包

2.在包中新建一个action类(继承ActionSupport类)

3.写入代码

(1)类中包含：表的实体类对象，Service接口的上转型对象，并提供get/set方法。

(2)注意：若表单中的元素是表中的属性(表的一列)，那么不用在action中为表单元素建立同name的成员变量，只要在表单中将元素的name改为：表的实体类对象名.属性名就能够。（这样在提交表单后，实体类对象的对应变量会自动被赋值，实体类对象表示的是表中的一行，也就是一条记录）

package action;

import java.sql.*;

import org.springframework.beans.factory.annotation.Autowired;

import com.opensymphony.xwork2.ActionSupport;

import lib.*;

public class AccountAction extends ActionSupport {
	
	Account account;
	@Autowired
	AccountService accountService;
	
	public String execute() throws Exception {
		account.setCreateDate(new Date(new java.util.Date().getTime()));
		accountService.save(account);
		return SUCCESS;
	}
	
	public String findById(String accountId) {
		Account acc = accountService.findById(accountId);
		System.out.println(acc);
		return SUCCESS;
	}
	
	public Account getAccount() {
		return account;
	}
	public void setAccount(Account account) {
		this.account = account;
	}
	public AccountService getAccountService() {
		return accountService;
	}
	public void setAccountService(AccountService accountService) {
		this.accountService = accountService;
	}

}

`八.配置struts.xml`

`1.在src/main/resources包下新建struts.xml文件`

`2.进行配置`

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN" "http://struts.apache.org/dtds/struts-2.5.dtd">
<struts>

	<constant name="struts.convention.action.packages" value="action"></constant>
	<constant name="struts.enable.DynamicMethodInvocation" value="true" />
	<package name="abc" namespace="/" extends="struts-default">
		<!-- 使表单经过（action的name属性）.方法名.action访问 指定action中的方法-->
		<global-allowed-methods>regex:.*</global-allowed-methods>
		<action name="Account*" class="action.AccountAction">
			<interceptor-ref name="defaultStack"></interceptor-ref>
			<result name="success">/succ.jsp</result>
			<result name="fail" type="redirect">/fail.jsp</result>
			<result name="input">/index.jsp</result>
		</action>
	</package>
</struts>

九.view层

1.在WebContent包下新建文件夹view

2.在view文件夹中新建jsp页面

3.写入代码

/*******************index.jsp***********************/
