Struts2+Spring+Hibernate整合开发（Maven多模块搭建）
0.项目结构
Struts2：web层
Spring：对象的容器
Hibernate：数据库持久化操作
1.父模块导入和管理所有需要的jar包
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.ssh</groupId> <artifactId>ssh_maven</artifactId> <packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <modules> <module>ssh_dao</module> <module>ssh_service</module> <module>ssh_web</module> </modules> <!-- 版本管理 --> <properties> <spring.version>4.2.4.RELEASE</spring.version> <hibernate.version>5.0.7.Final</hibernate.version> <struts.version>2.3.24</struts.version> </properties> <!-- 锁定版本 --> <dependencyManagement> <dependencies> <!-- spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- hibernate --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>${hibernate.version}</version> </dependency> <!-- struts2 --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>${struts.version}</version> </dependency> <!-- 整合的jar包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-spring-plugin</artifactId> <version>${struts.version}</version> </dependency> </dependencies> </dependencyManagement> <!-- 依赖管理，添加依赖的jar包 --> <dependencies> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>provided</scope> </dependency> <!-- spring相关 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> </dependency> <!-- hibernate --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> </dependency> <!-- struts2 --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> </dependency> <!-- 整合的jar包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-spring-plugin</artifactId> </dependency> <!-- 数据库驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> <!-- c3p0连接池 --> <dependency> <groupId>c3p0</groupId> <artifactId>c3p0</artifactId> <version>0.9.1.2</version> </dependency> <!-- 日志 --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.5</version> </dependency> <!-- jstl --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> </dependencies> <build> <!-- 配置插件 --> <plugins> <!-- 配置编译版本为jdk1.7 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.5.1</version> <configuration> <source>1.7</source> <target>1.7</target> <encoding>UTF-8</encoding> </configuration> </plugin> <!-- 配置tomcat7 --> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <!-- 配置工程路径 --> <path>/</path> <!-- 配置端口号 --> <port>8080</port> </configuration> </plugin> </plugins> </build> </project>
2.Dao模块
1）创建Hibernate核心配置文件（hibernate.cfg.xml；文件名不能修改）
主要设置一些配置以及读取元配置文件
<?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> <!-- 会话工厂 --> <session-factory> <!-- 数据库方言，根据数据库选择 --> <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property> <!--为了方便调试是否在运行hibernate时在日志中输出sql语句 --> <property name="hibernate.show_sql">true</property> <!-- 是否对日志中输出的sql语句进行格式化 --> <property name="hibernate.format_sql">true</property> <!-- 自动建表 --> <property name="hibernate.hbm2ddl.auto">update</property> <!-- 加载映射文件 --> <mapping resource="com/ssh/entity/Customer.hbm.xml"/> </session-factory> </hibernate-configuration>
2）创建元配置文件（Customer.hbm.xml；命名格式不能随便取）
可以根据该配置文件自动映射为表，该配置文件对应一个实体类
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<!-- Generated 2016-2-26 16:58:40 by Hibernate Tools 4.3.1.Final -->
<hibernate-mapping>
<class name="com.ssh.entity.Customer" table="cst_customer" optimistic-lock="version">
<id name="custId" type="java.lang.Long">
<column name="cust_id" />
<generator class="identity" />
</id>
<property name="custName" type="string">
<column name="cust_name" length="32" not-null="true"></column>
</property>
<property name="custUserId" type="java.lang.Long">
<column name="cust_user_id"></column>
</property>
<property name="custCreateId" type="java.lang.Long">
<column name="cust_create_id"></column>
</property>
<property name="custIndustry" type="string">
<column name="cust_industry" length="32"></column>
</property>
<property name="custLevel" type="string">
<column name="cust_level" length="32"></column>
</property>
<property name="custLinkman" type="string">
<column name="cust_linkman" length="64"></column>
</property>
<property name="custPhone" type="string">
<column name="cust_phone" length="64"></column>
</property>
<property name="custMobile" type="string">
<column name="cust_mobile" length="16"></column>
</property>
</class>
</hibernate-mapping>
3）创建Spring核心配置文件（applicationContext-dao.xml）
主要配置数据库的数据源（数据库连接池）；
Hibernate的工厂（创建SessionFactory工厂）；
配置事务管理；
<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.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 数据库连接池 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver" /> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssh_maven" /> <property name="user" value="root" /> <property name="password" value="admins" /> </bean> <!-- 配置sessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <!-- 依赖dataSource --> <property name="dataSource" ref="dataSource" /> <!-- 创建工厂需要加载hibernate映射文件 --> <property name="configLocations" value="classpath:hibernate.cfg.xml"></property> </bean> <bean id="customerDao" class="com.ssh.dao.impl.CustomerImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> </beans>
4）接口和实体类
package com.ssh.dao; import com.ssh.entity.Customer; public interface CustomerDao { /** * 通过id查询用户 * @param CustomerId * @return */ public Customer findCustomerById(Long CustomerId); }
package com.ssh.dao.impl; import com.ssh.dao.CustomerDao; import com.ssh.entity.Customer; import org.springframework.orm.hibernate5.support.HibernateDaoSupport; public class CustomerImpl extends HibernateDaoSupport implements CustomerDao { @Override public Customer findCustomerById(Long CustomerId) { return this.getHibernateTemplate().get(Customer.class, CustomerId); } }
package com.ssh.entity; public class Customer { private Long custId; private String custName; private Long custUserId; private Long custCreateId; private String custIndustry; private String custLevel; private String custLinkman; private String custPhone; private String custMobile; 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 Long getCustUserId() { return custUserId; } public void setCustUserId(Long custUserId) { this.custUserId = custUserId; } public Long getCustCreateId() { return custCreateId; } public void setCustCreateId(Long custCreateId) { this.custCreateId = custCreateId; } public String getCustIndustry() { return custIndustry; } public void setCustIndustry(String custIndustry) { this.custIndustry = custIndustry; } public String getCustLevel() { return custLevel; } public void setCustLevel(String custLevel) { this.custLevel = custLevel; } public String getCustLinkman() { return custLinkman; } public void setCustLinkman(String custLinkman) { this.custLinkman = custLinkman; } 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; } }
3.Service模块
1）依赖Dao模块
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>ssh_maven</artifactId> <groupId>com.ssh</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>ssh_service</artifactId> <dependencies> <dependency> <groupId>com.ssh</groupId> <artifactId>ssh_dao</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> </dependencies> </project>
2）创建Spring核心配置文件（applicationContext-service.xml）
主要用于管理Service
<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.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <import resource="classpath:applicationContext-dao.xml"/> <bean id="customerService" class="com.ssh.service.impl.CustomerServiceImpl"> <property name="customerDao" ref="customerDao"></property> </bean> </beans>
3）接口与实现
CustomerServiceCustomerServiceImpl4.Web模块
1）依赖Service模块
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<parent>
<artifactId>ssh_maven</artifactId>
<groupId>com.ssh</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>ssh_web</artifactId>
<packaging>war</packaging>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.7</maven.compiler.source>

</properties>
<dependencies>
<dependency>
<groupId>com.ssh</groupId>
<artifactId>ssh_service</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
</project>
2）创建Spring核心配置文件（applicationContext-action.xml）
主要用于管理Action
<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.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <import resource="classpath:applicationContext-service.xml"/> <bean id="customerAction" class="com.ssh.action.CustomerAction" scope="prototype"> <property name="customerService" ref="customerService"></property> </bean> </beans>
3）创建Struts2核心配置文件（struts.xml）
主要配置一些常量和请求规则
<?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> <!-- 配置常量 --> <!-- 字符集 --> <constant name="struts.i18n.encoding" value="UTF-8"></constant> <!-- 开发模式 --> <constant name="struts.devMode" value="true"></constant> <!-- 主题 --> <constant name="struts.ui.theme" value="simple"></constant> <!-- 扩展名 --> <!-- <constant name="struts.action.extension" value="action"></constant> --> <!-- 通用package --> <package name="customer" namespace="/" extends="struts-default"> <action name="customerAction_*" class="customerAction" method="{1}"> <result name="success">/info.jsp</result> </action> </package> </struts>
4）Action
package com.ssh.action; import com.opensymphony.xwork2.ActionSupport; import com.ssh.entity.Customer; import com.ssh.service.CustomerService; public class CustomerAction extends ActionSupport { //注入service private CustomerService customerService; //属性封装到custId private Long custId;//客户id //存放到值栈（get方式） private Customer customer;//客户信息 public CustomerService getCustomerService() { return customerService; } public void setCustomerService(CustomerService customerService) { this.customerService = customerService; } public Long getCustId() { return custId; } public void setCustId(Long custId) { this.custId = custId; } public Customer getCustomer() { return customer; } public void setCustomer(Customer customer) { this.customer = customer; } //action方法 public String queryCustomer(){ customer=customerService.findCustomerById(custId); return "success"; } }
5.Web.xml中的配置
配置监听器读取applicationContext-*.xml
配置Struts2的核心拦截器（过滤器）
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 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"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <!-- <param-value>classpath:applicationContext.xml</param-value> --> <param-value>classpath*:applicationContext-*.xml</param-value> </context-param> <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> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app>
6.其他一些配置
1）返回的页面
<%@ 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> 访问网址：http://localhost:8080/ssh/customerAction_queryCustomer.action?custId=1 这是一个信息页面 ${customer.custName } </body> </html>
2）数据库连接池
#加jdbc前缀的目的是为了避免后面的名字与其他地方名字冲突 jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/ssh_maven?characterEncoding=utf-8 jdbc.username=root jdbc.password=admins
3）日志
#日志文件 log4j.rootLogger=DEBUG,stdout log4j.logger.org.mybatis=DEBUG log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%5p %d %C: %m%n
至此SSH分模块整合完毕
