spring4 hibernate4 struts2 maven的整合

代碼并不規范，也沒有service層，目的只是在于說明三大框架如何整合在一起，適合于個人練習。
直接上代碼：
1 新建maven工程，pom.xml文件如下:

    </plugins>
</build>

</project></pre>

2 .spring配置文件 springMVC.xml,這里將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。 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="

</beans></pre>

jdbc.properties 

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&amp;characterEncoding=utf-8
jdbc.username=root
jdbc.password=root
 3 struts.xml的配置文件, 這里將action交給spring管理 

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
";
<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></pre>

4.web.xml,主要配置加載springMVC，struts2過濾器 <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi=":/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></pre>

5，實體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;
}

}</pre>

6Dao層：UserDao.java事務直接加在了dao上，只是為了測試就沒問題。 

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();
}

}</pre>

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";
    }
}</pre>

struts2調用方法的三種方式 

1在struts.xml中配置action時指定method 

2以感嘆號動態調用，要求配置中打開動態方法調用 



3以通配符調用（官方推薦） 

強調內容 

最后直接執行mvn build，因為pom中已經包含了tomcat7，goal中輸入：tomcat7:run 即可。
