Struts2+Spring+Hibernate的整合

整体程序结构

1、maven依赖

2、applicationContext.xml（spring配置文件）

<?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.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"><!--Spring IOC扫描 --><context:component-scan base-package="com.gdq"></context:component-scan><!--1、引用外部的配置文件 --><context:property-placeholder location="classpath:dbconfig.properties" /><!--2、配置数据库连接池 --><bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"init-method="init" destroy-method="close"><!-- 基本属性 url、user、password --><property name="driverClassName" value="${jdbc.driver}" /><property name="url" value="${jdbc.url}" /><property name="username" value="${jdbc.username}" /><property name="password" value="${jdbc.password}" /><!-- 配置监控统计拦截的filters --><property name="filters" value="stat" /><!-- 配置初始化大小、最小、最大 --><property name="maxActive" value="20" /><property name="initialSize" value="1" /><property name="minIdle" value="1" /><!-- 配置获取连接等待超时的时间 --><property name="maxWait" value="60000" /><!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --><property name="timeBetweenEvictionRunsMillis" value="60000" /><!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --><property name="minEvictableIdleTimeMillis" value="300000" /><property name="testWhileIdle" value="true" /><property name="testOnBorrow" value="false" /><property name="testOnReturn" value="false" /><!-- 打开PSCache，并且指定每个连接上PSCache的大小 --><property name="poolPreparedStatements" value="true" /><property name="maxOpenPreparedStatements" value="20" /></bean><!--3、配置SessionFactory --><bean id="sessionFactory"class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"><!--1、配置数据库连接池 --><property name="dataSource" ref="dataSource"></property><!--2、Hibernate的配置  --><property name="hibernateProperties"><props><prop key="hibernate.show_sql">true</prop><prop key="hibernate.format_sql">true</prop><prop key="hibernate.dialect">org.hibernate.dialect.MySQL57Dialect</prop><prop key="hibernate.hbm2ddl.auto">update</prop><prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate5.SpringSessionContext</prop></props></property><!-- 3、配置需要扫描的包 --><property name="packagesToScan" value="com.gdq.domain"></property></bean><!--4、配置事务管理器 --><bean id="txManager"class="org.springframework.orm.hibernate5.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"></property></bean><tx:annotation-driven transaction-manager="txManager" /><aop:aspectj-autoproxy></aop:aspectj-autoproxy></beans>

3、struts.xml（struts2配置）

<?xml version="1.0" encoding="UTF-8"?><!--加载约束文件 --><!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN""http://struts.apache.org/dtds/struts-2.5.dtd"><!--进行struts2的配置 --><struts><!--启用开发模式 --><constant name="struts.devMode" value="true"></constant><package name="base_package" extends="struts-default" namespace="/"><global-results><result name="success">/student.jsp</result><result name="error">/error.jsp</result></global-results><global-allowed-methods>regex:.*</global-allowed-methods></package><package name="student" extends="base_package"><interceptors><!-- 配置自定义拦截器 --><interceptor name="myi" class="com.gdq.web.interceptor.MyInterceptor"></interceptor><!--配置拦截器栈，为了提高拦截器的使用率  --><interceptor-stack name="myinterstatck"><!--引用自定义拦截器  --><interceptor-ref name="myi"></interceptor-ref><!--引用默认拦截器  --><interceptor-ref name="defaultStack"></interceptor-ref></interceptor-stack></interceptors><!--设置全局的拦截器  --><!-- <default-interceptor-ref name="myinterstatck"></default-interceptor-ref> --><!--新增  --><action name="add" class="studentAction" method="add"><!--设置文件上传拦截器  --><interceptor-ref name="defaultStack"><!--设置后缀名  --><param name="fileupload.allowedExtensions">.jpg,.png,.gif</param><!-- 设置最大的大小 --><param name="fileupload.maxmunSize">10000000</param><!--设置上传MIME类型  --><param name="fileupload.allowedTypes">image/*</param></interceptor-ref></action><!--删除  --><action name="delete" class="studentAction" method="delete"></action><!--修改  --><action name="update" class="studentAction" method="update"></action><!--查询  --><action name="query" class="studentAction" method="query"><interceptor-ref name="myi"></interceptor-ref></action></package></struts>

4、dbconfig.properties（数据库配置，引用阿里巴巴的druid）

jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/qf?characterEncoding=UTF-8jdbc.username=rootjdbc.password=123456

5、log4j.properties（日志文件，debug级）

6、web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://xmlns.jcp.org/xml/ns/javaee"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"version="3.1"><display-name>day21_S2SH</display-name><welcome-file-list><welcome-file>student.jsp</welcome-file></welcome-file-list><!--Spring的配置文件 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><!--Spring的监听器 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!--配置过滤器 --><filter><!--名称 --><filter-name>struts2</filter-name><!--Struts2的前端控制器的核心类 --><filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class></filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>

7、控制器示例（包含上传文件）

@Controllerpublic class StudentAction extends ActionSupport implements ModelDriven<Student>{@Autowiredprivate StudentService service;//上传的文件private File fileupload;//上传的文件名称private String fileuploadFileName;//上传文件的MIME类型private String fileuploadContentType;public File getFileupload() {return fileupload;}public void setFileupload(File fileupload) {this.fileupload = fileupload;}public String getFileuploadFileName() {return fileuploadFileName;}public void setFileuploadFileName(String fileuploadFileName) {this.fileuploadFileName = fileuploadFileName;}public String getFileuploadContentType() {return fileuploadContentType;}public void setFileuploadContentType(String fileuploadContentType) {this.fileuploadContentType = fileuploadContentType;}private Student  stu=new Student();@Overridepublic Student getModel() {// TODO Auto-generated method stubreturn stu;}//新增public String add() throws IOException {//进行头像的保存HttpServletRequest request=ServletActionContext.getRequest();File dir=new File(new File(request.getServletContext().getRealPath("/")).getParent(),"s2shImages");if(!dir.exists()) {dir.mkdirs();}//创建要保存的File对象File file=new File(dir, fileuploadFileName);//将上传的文件保存到服务器FileUtils.copyFile(fileupload, file);//设置图片的路径stu.setImgurl(dir.getName()+File.separator+file.getName());System.out.println("新增："+service.save(stu));return "success";}//删除public String delete() {service.delete(stu);return "success";}//修改public String update() {service.update(stu);return "success";}//查询public String query() {HttpServletRequest request=ServletActionContext.getRequest();request.setAttribute("list", service.queryAll());return "success";}

8、service层

@Service@Transactionalpublic class StudentService {@Autowiredprivate StudentDao dao;// 新增public Long save(Student student) {return dao.save(student);}// 修改public void update(Student student) {dao.update(student);}// 删除public void delete(Student student) {dao.delete(student);}// 查询public List<Student> queryAll() {return dao.queryAll();}}

9、dao层

@Repositorypublic class StudentDao {@Autowiredprivate SessionFactory factory;//新增public Long save(Student student) {return (Long)factory.getCurrentSession().save(student);}//修改public void update(Student student) { factory.getCurrentSession().update(student);}//删除public void delete(Student student) {factory.getCurrentSession().delete(student);}//查询public List<Student> queryAll() {return factory.getCurrentSession().createQuery("from Student", Student.class).getResultList();}}

10.domain层（实体层）

@Entity@Table(name="t_student")public class Student implements Serializable{@Id@GeneratedValue(strategy=GenerationType.IDENTITY)private Long id;@Column(length=10)private String name;@Column(length=2)private String sex;private int age;@Column(length=11)private String phone;@Column(length=200)private String imgurl;public String getImgurl() {return imgurl;}public void setImgurl(String imgurl) {this.imgurl = imgurl;}public Long getId() {return id;}public void setId(Long id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getPhone() {return phone;}public void setPhone(String phone) {this.phone = phone;}}
