MAVEN SSH的框架整合

• SSH 是 struts,spring和hibernate 合成的一个集成框架，是目前目前比较流行的web应用程序开源框架，（这是官方的介绍，个人认为SSM要比它好一点了）

一.hibernate

1.引入hibernate

<!-- 引入Servlet依赖 -->    <dependency>        <groupId>javax.servlet</groupId>        <artifactId>javax.servlet-api</artifactId>        <version>4.0.0</version>        <scope>provided</scope><!-- 引入Hibernate依赖 -->    <dependency>        <groupId>org.hibernate</groupId>        <artifactId>hibernate-core</artifactId>        <version>5.2.12.Final</version>    </dependency>    <!-- 引入Mysql依赖 -->    <dependency>        <groupId>mysql</groupId>        <artifactId>mysql-connector-java</artifactId>        <version>5.1.43</version>    </dependency>

2.写个hibernate.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="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>        <property name="hibernate.connection.password">password</property>        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>        <property name="hibernate.connection.username">root</property>        <!-- 显示sql语句 -->        <property name="show_sql">true</property>        <!-- 格式化sql语句 -->        <property name="format_sql">true</property>        <!-- 关联映射文件 -->        <mapping resource="com/guard/entity/StudentEntity.hbm.xml"/>    </session-factory></hibernate-configuration>

• 3.写个实体类 并 配置一个映射文件
• 

映射文件:

<?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 2017-12-18 0:26:15 by Hibernate Tools 3.5.0.Final --><hibernate-mapping>    <class name="com.guard.entity.StudentEntity" table="student">        <id name="sid" type="int">            <column name="SID" />            <generator class="increment" />        </id>        <property name="sname" type="java.lang.String">            <column name="SNAME" />        </property>        <property name="age" type="int">            <column name="AGE" />        </property>    </class></hibernate-mapping>

• 5.进行测试

public class TestHibernate {    @Test    public void test(){        //测试Hibernate框架，对数据进行CRUD        //读取hibernate配置文件        Configuration configuration = new Configuration().configure();        //通过configuration获取sessionfactory        SessionFactory sessionFactory = configuration.buildSessionFactory();        //通过sessionfactory获取session        Session session = sessionFactory.openSession();        //开启事务        Transaction transaction = session.beginTransaction();        //操作        session.save(new StudentEntity("admin", 18));        //提交事务        transaction.commit();        //关闭        session.close();        sessionFactory.close();    }}

成功了

二.Spring

• 1.引入依赖

<!-- 引入Spring依赖 -->    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-context</artifactId>        <version>4.3.10.RELEASE</version>    </dependency>    <!-- 引入c3p0数据库连接池 -->    <dependency>        <groupId>com.mchange</groupId>        <artifactId>c3p0</artifactId>        <version>0.9.5.1</version>    </dependency>    <!-- 引入Hibernate整合Spring -->    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-orm</artifactId>        <version>4.3.10.RELEASE</version>    </dependency>    <!-- 引入spring-aspects:解析事务的表达式 -->    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-aspects</artifactId>        <version>4.3.10.RELEASE</version>    </dependency>

• 2.写个db.properties
• 注释hibernate

db.properties 把hibernate的数据库连接拿出来

uname=rootupass=1234url=jdbc:mysql://localhost:3306/ltdriverClass=com.mysql.jdbc.DriverinitPoolSize=10maxPoolSize=20

注释一部分hibernate 拿出来就注释

<?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="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>        <property name="hibernate.connection.password">password</property>        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>        <property name="hibernate.connection.username">root</property> -->        <!-- 显示SQL语句 -->        <property name="show_sql">true</property>        <!-- 格式化SQL语句 -->        <property name="format_sql">true</property>        <!-- 关联映射文件 -->       <!--  <mapping resource="com/guard/entity/StudentEntity.hbm.xml"/> -->    </session-factory></hibernate-configuration>

• 3.写applicationContext-public.xml配置sessionfactory，数据源，连接池，和事务

<?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:aop="http://www.springframework.org/schema/aop"    xmlns:tx="http://www.springframework.org/schema/tx"    xmlns:c="http://www.springframework.org/schema/c"    xmlns:context="http://www.springframework.org/schema/context"    xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans.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        http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-4.3.xsd">    <!-- 引入db.properties -->    <context:property-placeholder location="classpath:db.properties"/>    <!-- 配置数据源：配置数据库连接池c3p0 -->    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">        <property name="user" value="${uname}"></property>        <property name="password" value="${upass}"></property>        <property name="jdbcUrl" value="${url}"></property>        <property name="driverClass" value="${driverClass}"></property>        <property name="initialPoolSize" value="${initPoolSize}"></property>        <property name="maxPoolSize" value="${maxPoolSize}"></property>    </bean>    <!-- 配置sessionFactory -->    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">        <!-- 引入数据源 -->        <property name="dataSource" ref="dataSource"></property>        <!-- 加载hibernate配置文件 -->        <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>        <!-- 加载映射文件 -->        <property name="mappingLocations" value="classpath:com/guard/entity/*.hbm.xml"></property>    </bean>    <!-- 配置事务管理器 -->    <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">        <property name="sessionFactory" ref="sessionFactory"></property>        </bean>    <!-- 配置事务的属性 -->    <tx:advice id="myAdvice" transaction-manager="transactionManager">        <tx:attributes>            <tx:method name="add*" propagation="REQUIRED"/>            <tx:method name="update*" propagation="REQUIRED"/>            <tx:method name="delete*" propagation="REQUIRED"/>            <tx:method name="*"/>        </tx:attributes>    </tx:advice>    <!-- 配置事务的切点 -->    <aop:config>        <aop:pointcut expression="execution(* com.guard.dao.*.*(..))" id="myPoint"/>        <aop:advisor advice-ref="myAdvice" pointcut-ref="myPoint"/>    </aop:config></beans>

• 4 写applicationContext-biz.xml和applicationContext-dao的路径

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">    <bean id="studentBizImpl" class="com.guard.biz.StudentBizImpl">        <property name="studentDao" ref="studentDaoImpl"></property>    </bean></beans><!-- dao--!><?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans.xsd">    <bean id="studentDaoImpl" class="com.guard.dao.StudentDaoImpl">        <property name="sessionFactory" ref="sessionFactory"></property>    </bean></beans>

• 写dao 和 biz
  

package com.guard.dao;import org.hibernate.Session;import org.hibernate.SessionFactory;import com.guard.entity.StudentEntity;public class StudentDaoImpl implements StudentDao{    private SessionFactory sessionFactory;    public SessionFactory getSessionFactory() {        return sessionFactory;    }    public void setSessionFactory(SessionFactory sessionFactory) {        this.sessionFactory = sessionFactory;    }    public Session getSession(){        return sessionFactory.getCurrentSession();    }    public void add(StudentEntity studentEntity) {        getSession().save(studentEntity);    }}<!--biz --!>package com.guard.biz;import com.guard.dao.StudentDao;import com.guard.entity.StudentEntity;public class StudentBizImpl implements StudentBiz{    private StudentDao studentDao;    public StudentDao getStudentDao() {        return studentDao;    }    public void setStudentDao(StudentDao studentDao) {        this.studentDao = studentDao;    }    public void add(StudentEntity studentEntity) {        // TODO Auto-generated method stub        studentDao.add(studentEntity);    }}

• 5.测试
  

  Struts

• 1.引入依赖

<!-- 引入Struts2依赖 -->        <dependency>            <groupId>org.apache.struts</groupId>            <artifactId>struts2-core</artifactId>            <version>2.3.33</version>        </dependency>        <!-- struts2整合Spring的 插件包 -->        <dependency>            <groupId>org.apache.struts</groupId>            <artifactId>struts2-spring-plugin</artifactId>            <version>2.5.12</version>        </dependency>        <!-- log4J -->        <dependency>            <groupId>org.apache.logging.log4j</groupId>            <artifactId>log4j-core</artifactId>            <version>2.8.2</version>        </dependency>

• 2写个action

package com.guard.action;import com.opensymphony.xwork2.ActionSupport;import com.guard.biz.StudentBiz;import com.guard.entity.StudentEntity;public class StudentAction extends ActionSupport{    private StudentEntity studentEntity;    private StudentBiz studentBiz;    public StudentEntity getStudentEntity() {        return studentEntity;    }    public void setStudentEntity(StudentEntity studentEntity) {        this.studentEntity = studentEntity;    }    public StudentBiz getStudentBiz() {        return studentBiz;    }    public void setStudentBiz(StudentBiz studentBiz) {        this.studentBiz = studentBiz;    }    public String add()throws Exception{        studentBiz.add(studentEntity);        return this.SUCCESS;    }}

• applicationContext-action路径

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">    <bean id="StudentAction" class="com.guard.action.StudentAction" scope="prototype">        <property name="studentBiz" ref="studentBizImpl"></property>    </bean></beans>

• 3.配置struts.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"    "http://struts.apache.org/dtds/struts-2.3.dtd">    <struts>        <package name="myPackage" extends="struts-default">            <action name="student*" class="studentAction" method="{1}">                <result>/success.jsp</result>            </action>        </package>    </struts>

• 4.写个jsp测试

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!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=UTF-8"><title>Insert title here</title></head><body>    <form action="studentadd.action" method="post">        姓名：<input type="text" name="student.sname"/><br/>        年龄：<input type="text" name="student.age"/><br/>        <input type="submit" value="添加"/><br/>    </form></body></html>

• 这个jsp看看上一个jsp有没有跳转

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!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=UTF-8"><title>Insert title here</title></head><body>success</body></html>

• 最后web.xml的配置

<!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>  <!-- needed for ContextLoaderListener -->    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:applicationContext-*.xml</param-value>    </context-param>  <!-- 加载struts2 -->  <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>  <!-- 加载spring -->    <!-- Bootstraps the root web application context before servlet initialization -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener></web-app>

这是一个路径的 还有一个是注解的 ！
