10年前
代码并不规范，也没有service层，目的只是在于说明三大框架如何整合在一起，适合于个人练习。
直接上代码：
1 新建maven工程，pom.xml文件如下:
<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.abigdreamer.ark</groupId> <artifactId>demo</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <name>data-permission</name> <url>http://maven.apache.org</url> <properties> <org.hibernate.version>4.1.2</org.hibernate.version> <org.springframework-version>4.0.3.RELEASE</org.springframework-version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.10</version> <scope>test</scope> </dependency> <dependency> <groupId>cglib</groupId> <artifactId>cglib</artifactId> <version>2.2.2</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.14</version> <scope>provided</scope> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.21</version> </dependency> <!-- hibernate 4.3.0 start --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>4.3.0.Final</version> </dependency> <dependency> <groupId>org.hibernate.javax.persistence</groupId> <artifactId>hibernate-jpa-2.0-api</artifactId> <version>1.0.1.Final</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-ehcache</artifactId> <version>4.3.0.Final</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>5.1.0.Alpha1</version> </dependency> <dependency> <groupId>org.hibernate.common</groupId> <artifactId>hibernate-commons-annotations</artifactId> <version>4.0.4.Final</version> </dependency> <!-- hibernate 4.3.0 end --> <!-- spring start --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${org.springframework-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${org.springframework-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${org.springframework-version}</version> <type>jar</type> <scope>compile</scope> </dependency> <!-- spring end --> <!-- servlet jsp --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>2.3.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-dbcp2</artifactId> <version>2.0</version> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${org.springframework-version}</version> <type>jar</type> <scope>compile</scope> </dependency> <!-- struts2 --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>2.3.1.2</version> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-spring-plugin</artifactId> <version>2.3.1.2</version> </dependency> <!-- struts2注解零配置依赖的包 --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-convention-plugin</artifactId> <version>2.3.1</version> </dependency> <!-- struts2标签 --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts-taglib</artifactId> <version>1.3.10</version> </dependency> </dependencies> <build> <finalName>demo</finalName> <plugins> <!-- <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>tomcat-maven-plugin</artifactId> </plugin> --> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.1</version> <configuration> <port>8088</port> </configuration> </plugin> </plugins> </build> </project>2 .spring配置文件 springMVC.xml,这里将hibernate的配置文件：hbm使用注解代替，cfg主配置文件直接在spring配置文件中配置。

jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8 jdbc.username=root jdbc.password=root
3 struts.xml的配置文件, 这里将action交给spring管理
<?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-2.0.dtd"> <struts> <constant name="struts.enable.DynamicMethodInvocation" value="true" /> <constant name="struts.devMode" value="true"/> <constant name="struts.i18n.encoding" value="UTF-8" /> <constant name="struts.convention.result.path" value="/WEB-INF/pages"/> <constant name="struts.convention.package.locators" value="web,action"/> <constant name="struts.objectFactory" value="spring"/> <constant name="struts.configuration.xml.reload" value="true"/> </struts>
4.web.xml,主要配置加载springMVC，struts2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" version="2.5"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:/springMVC.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <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> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <init-param> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> --> <!-- <servlet> <servlet-name>spring3mvc</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:/springMVC.xml</param-value> </init-param> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring3mvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> --> <display-name>Struts 2 Web Application</display-name> <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>/WEB-INF/pages/index.jsp</welcome-file> </welcome-file-list> </web-app>
5，实体User如下：
package com.syb.entity; import java.util.Date; public class Event { private Long id; private String title; private Date date; public Event() {} public Long getId() { return id; } private void setId(Long id) { this.id = id; } public Date getDate() { return date; } public void setDate(Date date) { this.date = date; } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } }6Dao层：UserDao.java事务直接加在了dao上，只是为了测试就没问题。
package com.syb.dao; import java.util.Date; import java.util.List; import javax.transaction.Transactional; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import org.springframework.stereotype.Component; import com.syb.entity.Employee; @Component @Transactional public class UserDao { @Autowired SessionFactory sessionFactory; public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("springMVC.xml"); SessionFactory factory = (SessionFactory) context.getBean("sessionFactory"); Session session = factory.getCurrentSession(); Transaction transaction = session.beginTransaction(); for (int i =31; i < 40; i++) { Employee emp = new Employee(); emp.setName("David"+i); emp.setRole("Developer"+i); emp.setInsertTime(new Date()); session.save(emp); } session.flush(); transaction.commit(); } public List<Employee> list() { return sessionFactory.openSession().createQuery("from Employee").list(); } }7最后是action UserAction.java
package com.syb.web; import org.apache.struts2.ServletActionContext; import org.apache.struts2.convention.annotation.Action; import org.apache.struts2.convention.annotation.Result; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import com.syb.dao.UserDao; import com.syb.entity.Employee; @Component @Action(value="userAction",results= {@Result(name = "success", location = "/WEB-INF/pages/index.jsp")}) public class UserAction { @Autowired private UserDao muserDao; // @Action(value = "list", results = {@Result(name = "success", location = "/WEB-INF/pages/index.jsp")}) public String list() { String resultString =""; for (Employee e:muserDao.list()) { resultString+=e.getName()+" :"+e.getRole()+"\r\n"; } ServletActionContext.getRequest().setAttribute("result", resultString); return "success"; } }struts2调用方法的三种方式
1在struts.xml中配置action时指定method
2以感叹号动态调用，要求配置中打开动态方法调用
3以通配符调用（官方推荐）
强调内容
最后直接执行mvn build，因为pom中已经包含了tomcat7，goal中输入：tomcat7:run 即可。
