【01】SSH练习——整合SSH

1、所需jar包

2、配置Spring

(1)导入需要的jar包

(2)配置文件bean.xml 下面给出的xml文件是整合完毕之后的

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" 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-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- 配置DataSource --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="user" value="root" /> <property name="driverClass" value="com.mysql.jdbc.Driver" /> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test" /> <property name="password" value="1234" /> </bean> <!-- 配置SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="classpath:hibernate.cfg.xml" /> </bean> <!-- 配置TransactionManager --> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- 配置Advice --> <tx:advice id="advice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="save*" propagation="REQUIRED"/> <tx:method name="delete*" propagation="REQUIRED"/> <tx:method name="update*" propagation="REQUIRED"/> <tx:method name="*" propagation="SUPPORTS"/> </tx:attributes> </tx:advice> <!-- 配置aop --> <aop:config> <aop:pointcut expression="execution(* com.cqb.service.*.*(..))" id="pointcut"/> <aop:advisor advice-ref="advice" pointcut-ref="pointcut"/> </aop:config> <!-- 配置Service --> <bean id="categoryService" class="com.cqb.service.CategoryServiceImp"> <property name="sessionFactory" ref="sessionFactory"/> </bean> <!-- 配置Action --> <bean id="categoryAction" class="com.cqb.action.CategoryAction" scope="prototype"> <property name="categoryService" ref="categoryService" /> </bean> </beans>(3)测试Spring是否配置完成

3、配置整合hibernate

(1)导入jar包

(2)创建配置文件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> <!-- <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.password">1234</property> <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property> <property name="hibernate.connection.username">root</property> --> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <property name="show_sql">true</property> <mapping class="com.cqb.bean.Category"/> </session-factory> </hibernate-configuration>

注释掉的部分在bean.xml中配置

(3)在bean.xml中配置dataSource

(4)在bean.xml中配置sessionFactory

(5)使用Hibernate Tools逆向生成永久类

package com.cqb.bean; // Generated 2017-4-12 19:15:33 by Hibernate Tools 4.3.5.Final import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import static javax.persistence.GenerationType.IDENTITY; import javax.persistence.Id; import javax.persistence.Table; /** * Category generated by hbm2java */ @Entity @Table(name = "category", catalog = "test") public class Category implements java.io.Serializable { private Integer id; private String type; private Boolean hot; public Category() {}; public Category(int i, String string, boolean b) { } public Category(String type, Boolean hot) { this.type = type; this.hot = hot; } @Id @GeneratedValue(strategy = IDENTITY) @Column(name = "id", unique = true, nullable = false) public Integer getId() { return this.id; } public void setId(Integer id) { this.id = id; } @Column(name = "type", length = 20) public String getType() { return this.type; } public void setType(String type) { this.type = type; } @Column(name = "hot") public Boolean getHot() { return this.hot; } public void setHot(Boolean hot) { this.hot = hot; } }

(6)创建Service用于测试

package com.cqb.service; import com.cqb.bean.Category; public interface CategoryService { public void save(Category category) ; public void update(Category category); public Category findById(int id); } package com.cqb.service; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration; import com.cqb.bean.Category; import sun.print.resources.serviceui; public class CategoryServiceImp implements CategoryService { private SessionFactory sessionFactory; public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } public SessionFactory getSessionFactory() { return sessionFactory; } @Override public void save(Category category) { sessionFactory.getCurrentSession().save(category); } @Override public void update(Category category) { sessionFactory.getCurrentSession().update(category); } @Override public Category findById(int id) { // TODO Auto-generated method stub return (Category) sessionFactory.getCurrentSession().get(Category.class, id); } } (7)在bean.xml中配置service

(8)在bean.xml中配置transactionManager

(9)在bean.xml中配置advice和aop

(10)测试

4、配置和整合struts2

(1)导入所需jar包

(2)创建web.xml和struts.xml

(3)在web.xml中写入Spring的Listener

<?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>E_shop</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <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> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:beans.xml</param-value> </context-param> </web-app>

(4)创建action 并在bean.xml和struts.xml中配置

package com.cqb.action; import com.cqb.bean.Category; import com.cqb.service.CategoryService; import com.opensymphony.xwork2.ActionSupport; public class CategoryAction extends ActionSupport { private CategoryService categoryService; private Category category; public void setCategory(Category category) { this.category = category; } public Category getCategory() { return category; } public void setCategoryService(CategoryService categoryService) { this.categoryService = categoryService; } public String save() { categoryService.save(category); return "index"; } public String update() { categoryService.update(category); return "index"; } }

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="shop" extends="struts-default" namespace="/"> <!-- category_update.actiocan： 访问update方法 --> <action name="category_*" class="categoryAction" method="{1}"> <result name="index">/index.jsp</result> </action> </package> </struts> (5)编写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> <a href="category_save.action?category.type=gga&category.hot=false">访问save</a> <a href="category_update.action?category.id=2&category.type=g&category.hot=true">访问update</a> </body> </html> 以上 就完成了对ssh的整合

hibernate和spring的测试使用Junit4

import java.util.Date; import javax.annotation.Resource; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import com.cqb.bean.Category; import com.cqb.service.CategoryService; import com.cqb.service.CategoryServiceImp; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="classpath:beans.xml") public class SSHTest { @Resource private CategoryService categoryService; @Resource private Date date; public void setCategoryService(CategoryService categoryService) { this.categoryService = categoryService; } public CategoryService getCategoryService() { return categoryService; } /* @Test //测试Spring IOC的开发环境 public void springIoc() { System.out.println(date); } */ @Test //测试Hibernate的开发环境，因为没有整合，可以直接new public void hihernate() { Category category = categoryService.findById(1); category.setType("chenqingb"); categoryService.update(category); System.out.println("hahahahaha"); } }
