基于maven项目的ssh框架搭建(分层概念)

1.新建maven项目。https://blog.youkuaiyun.com/qq_36489998/article/details/80525010

        项目的目录如下：

        

        其中ssh-webapp依赖ssh-service ---->ssh-service依赖ssh-dao ----->ssh-dao依赖ssh-domain

2.在ssh父项目的pom文件中加入jar依赖

</project>

3.在resources文件夹下新建applicationContext.xml     hibernate.cfg.xml     struts.xml  三个文件


1》.applicationContext.xml

<?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:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
		
	<!-- 配置自动扫描的包 -->
    <context:component-scan base-package="club.jiajiajia.ssh"></context:component-scan>
    
    <!-- 配置数据源 -->
    <bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="user" value="root"></property>
		<property name="password" value="19960215"></property>
		<property name="jdbcUrl" value="jdbc:mysql:///ssh?characterEncoding=utf-8"></property>
		<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
		<property name="maxPoolSize" value="20"></property>
		<property name="initialPoolSize" value="10"></property>
	</bean>
	<!-- 配置sessionFactory -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" scope="prototype">
    	<property name="dataSource" ref="dataSource"></property>
        <!-- 注入Hibernate 配置文件路径,前面要加上  classpath:-->
        <property name="configLocation" value="classpath:hibernate.cfg.xml"/>
    </bean>

</beans>
2.》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>
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="show_sql">true</property>
        <property name="format_sql">true</property>
        <property name="hbm2ddl.auto">update</property> 
        
        <mapping class="club.jiajiajia.ssh.User"/>
        
    </session-factory>
</hibernate-configuration>
3.》struts.xml 
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    <package name="default" namespace="/" extends="struts-default">
    	<action name="test" class="club.jiajiajia.ssh.TestAction" method="test">
    		<result name="success">/success.jsp</result>
    	</action>
	</package>
    
</struts>

4.》修改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_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>weblog</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>main.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <!-- struts过滤器 -->
  <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>*.action</url-pattern>
  </filter-mapping>
  
 <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
</web-app>

3.在webapp文件夹下新建index.jsp    success.jsp

    1>index.jsp

    

<html>
<body>
<h2><a href="test.action">Hello World!</a></h2>
</body>
</html>

    2.>success.jsp

       

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
	success
</body>
</html>

4.在ssh-webapp下新建java类

    

    TestAtion.java

package club.jiajiajia.ssh;

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

@Controller
public class TestAction {
	@Autowired
	private TestServlet testServlet;
	public String test() {
		testServlet.add();
		System.out.println("测试success");
		return "success";
	}
}

5.在ssh-service下新建java类


TestServlet.java

package club.jiajiajia.ssh;

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

@Service
public class TestServlet {
	@Autowired
	private TestDao testDao;
	public void add() {
		testDao.testDao();
	}
}

6.在ssh-dao层下建java类

TestDao.java

package club.jiajiajia.ssh;

import javax.persistence.Access;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

@Repository
public class TestDao {
	@Autowired
	private SessionFactory sessionFactory;
	public void testDao() {
		System.out.println(sessionFactory);
	}
}

6.在ssh-domain下新建java类

User.java


package club.jiajiajia.ssh;

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

@Entity
@Table(name="user")
public class User {
	@Id
	@GeneratedValue
	private Integer id;
	private String name;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public User() {
		super();
		// TODO Auto-generated constructor stub
	}
	public User(Integer id, String name) {
		super();
		this.id = id;
		this.name = name;
	}
	@Override
	public String toString() {
		return "User [id=" + id + ", name=" + name + "]";
	}
	
}
