SSH框架整合

第一步導入Jar包

導入的jar包在《SSH框架整合——基于xml配置文件》博文中都有所介紹，這里不再贅述。唯一不同的是，基于注解的SSH整合還需要導入Struts2注解整合包struts2-convention-plugin-x.x.x.jar。

第二步導入配置文件

db.propertiesjdbc.driverClass=com.MySQL.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/testjdbc.user=rootjdbc.passWord=123456applicationContext.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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd 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">  <context:property-placeholder location="classpath:db.properties"/>  <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="${jdbc.driverClass}"/> <property name="jdbcUrl" value="${jdbc.url}"/> <property name="user" value="${jdbc.user}"/> <property name="password" value="${jdbc.password}"/> </bean></beans>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"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> <welcome-file>index.html</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>/*</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>log4j.properties### direct log messages to stdout ###log4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.Target=System.errlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n### direct messages to file mylog.log ###log4j.appender.file=org.apache.log4j.FileAppenderlog4j.appender.file.File=c/:mylog.loglog4j.appender.file.layout=org.apache.log4j.PatternLayoutlog4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n### set log levels - for more verbose logging change 'info' to 'debug' ###log4j.rootLogger=info, stdout

第三步創建相關的包和類

package com.pc.crm.domain;import java.io.Serializable;/** * 客戶實體類 * Created by Switch on 2016/12/3. */public class Customer implements Serializable {}package com.pc.crm.dao;/** * 客戶持久層接口 * Created by Switch on 2016/12/3. */public interface CustomerDao {}package com.pc.crm.dao.impl;import com.pc.crm.dao.CustomerDao;/** * 客戶持久層接口實現類 * Created by Switch on 2016/12/3. */public class CustomerDaoImpl implements CustomerDao {}package com.pc.crm.service;/** * 客戶服務接口 * Created by Switch on 2016/12/3. */public interface CustomerService {}package com.pc.crm.service.impl;import com.pc.crm.service.CustomerService;/** * 客戶服務接口實現類 * Created by Switch on 2016/12/3. */public class CustomerServiceImpl implements CustomerService {}package com.pc.crm.web.action;import com.opensymphony.xwork2.ActionSupport;import com.opensymphony.xwork2.ModelDriven;import com.pc.crm.domain.Customer;/** * 客戶Action * Created by Switch on 2016/12/3. */public class CustomerAction extends ActionSupport implements ModelDriven<Customer> { // 模型驅動對象 private Customer customer = new Customer(); @Override public Customer getModel() { return this.customer; }}

第四步創建界面

<%@ page contentType="text/html;charset=UTF-8" language="java" pageEncoding="utf-8" %><%@ taglib prefix="s" uri="/struts-tags" %><!DOCTYPE HTML><html> <head> <title>首頁</title> <meta charset="utf-8"> </head> <body> <s:form action="customer_save" namespace="/customer" method="post"> <s:textfield name="custName" maxLength="50" CSSStyle="WIDTH: 180px" label="客戶名稱"/> <s:textfield name="custPhone" maxLength="50" cssStyle="WIDTH: 180px" label="固定電話"/> <s:textfield name="custMobile" maxLength="50" cssStyle="WIDTH: 180px" label="移動電話"/> <s:submit value="保存"/> </s:form> </body></html>

第五步配置組件注解掃描

在applicationContext.xml中添加<context:component-scan base-package="com.pc.crm.web.action"/><context:component-scan base-package="com.pc.crm.*.impl"/>

第六步配置Action注解

package com.pc.crm.web.action;import com.opensymphony.xwork2.ActionSupport;import com.opensymphony.xwork2.ModelDriven;import com.pc.crm.domain.Customer;import com.pc.crm.service.CustomerService;import org.apache.struts2.convention.annotation.Action;import org.apache.struts2.convention.annotation.Namespace;import org.apache.struts2.convention.annotation.ParentPackage;import org.springframework.beans.factory.config.ConfigurableBeanFactory;import org.springframework.context.annotation.Scope;import org.springframework.stereotype.Controller;import javax.annotation.Resource;/** * 客戶Action * Created by Switch on 2016/12/3. */// 控制器組件注解，用于Web層@Controller("customerAction")// Action是多例的，所以需要配置為Prototype范圍@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)// Struts2的注解// 等價于Struts2配置文件中的package元素的extends屬性@ParentPackage("struts-default")// 等價于Struts2配置文件中的package元素的namespace屬性@Namespace("/customer")public class CustomerAction extends ActionSupport implements ModelDriven<Customer> { @Resource(name = "customerService") // 注入客戶服務對象 private CustomerService customerService; // 模型驅動對象 private Customer customer = new Customer(); @Override public Customer getModel() { return this.customer; } // 等價于Struts2配置文件中的action元素的name屬性和method屬性的復合 @Action("customer_save") public String save() { System.out.println("Action的Save方法執行了"); customerService.save(customer); return NONE; }}

第七步配置業務層接口和實現類

package com.pc.crm.service;import com.pc.crm.domain.Customer;/** * 客戶服務接口 * Created by Switch on 2016/12/3. */public interface CustomerService { /** * 保存客戶 * * @param customer */ void save(Customer customer);}package com.pc.crm.service.impl;import com.pc.crm.dao.CustomerDao;import com.pc.crm.domain.Customer;import com.pc.crm.service.CustomerService;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;import javax.annotation.Resource;/** * 客戶服務接口實現類 * Created by Switch on 2016/12/3. */// 服務層組件注解，用于服務層@Service("customerService")// 配置事務，使用默認配置@Transactionalpublic class CustomerServiceImpl implements CustomerService { @Resource(name = "customerDao") // 注入客戶持久層對象 private CustomerDao customerDao; @Override public void save(Customer customer) { System.out.println("Service中的save方法執行了"); customerDao.save(customer); }}

第八步配置實體類和映射注解

package com.pc.crm.domain;import javax.persistence.*;import java.io.Serializable;/** * 客戶實體類 * Created by Switch on 2016/12/3. */// 配置為實體類@Entity// 配置對應的表名@Table(name = "cst_customer")public class Customer implements Serializable { // 配置ID，主鍵 @Id // 配置主鍵生成策略為由底層數據庫生成 @GeneratedValue(strategy = GenerationType.IDENTITY) // 配置數據庫中字段的名字等屬性 @Column(name = "cust_id") private Long custId; // 客戶編號(主鍵) @Column(name = "cust_name") private String custName; // 客戶名稱(公司名稱) @Column(name = "cust_phone") private String custPhone; // 固定電話 @Column(name = "cust_mobile") private String custMobile; // 移動電話 public Long getCustId() { return custId; } public void setCustId(Long custId) { this.custId = custId; } public String getCustName() { return custName; } public void setCustName(String custName) { this.custName = custName; } public String getCustPhone() { return custPhone; } public void setCustPhone(String custPhone) { this.custPhone = custPhone; } public String getCustMobile() { return custMobile; } public void setCustMobile(String custMobile) { this.custMobile = custMobile; } @Override public String toString() { return "Customer{" + "custId=" + custId + ", custName='" + custName + '/'' + ", custPhone='" + custPhone + '/'' + ", custMobile='" + custMobile + '/'' + '}'; }}

第九步配置會話工廠

在applicationContext.xml中添加<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">  <property name="dataSource" ref="dataSource"/>  <property name="hibernateProperties"> <props>  <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>  <prop key="hibernate.show_sql">true</prop>    <prop key="hibernate.hbm2ddl.auto">update</prop> </props> </property>  <property name="packagesToScan"> <list> <value>com.pc.crm.domain</value> </list> </property></bean>

第十步配置Hibernate模板

在applicationContext.xml中添加<bean id="hibernateTemplate" class="org.springframework.orm.hibernate5.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory"/></bean>

第十一步配置事務管理器和事務注解掃描

在applicationContext.xml中添加<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/></bean><tx:annotation-driven transaction-manager="transactionManager"/>

第十二步配置持久層接口和實現類

package com.pc.crm.dao;import com.pc.crm.domain.Customer;/** * 客戶持久層接口 * Created by Switch on 2016/12/3. */public interface CustomerDao { /** * 保存客戶 * * @param customer */ void save(Customer customer);}package com.pc.crm.dao.impl;import com.pc.crm.dao.CustomerDao;import com.pc.crm.domain.Customer;import org.springframework.orm.hibernate5.HibernateTemplate;import org.springframework.stereotype.Repository;import javax.annotation.Resource;/** * 客戶持久層接口實現類 * Created by Switch on 2016/12/3. */// 持久層組件注解，用于持久層@Repository("customerDao")public class CustomerDaoImpl implements CustomerDao { @Resource(name = "hibernateTemplate") // 注入Hibernate模板 private HibernateTemplate hibernateTemplate; @Override public void save(Customer customer) { System.out.println("Dao中的save方法執行了"); this.hibernateTemplate.save(customer); }}

配置OpenSessionInView過濾器

在web.xml中添加，注意要放在Struts2核心過濾器上面<filter> <filter-name>OpenSessionInViewFilter</filter-name> <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class></filter><filter-mapping> <filter-name>OpenSessionInViewFilter</filter-name> <url-pattern>*.action</url-pattern></filter-mapping>

配置全站編碼過濾器

在web.xml中添加，注意要放在Struts2核心過濾器上面<filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param></filter><filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern></filter-mapping>
