之前,我介绍了spring 3 + hibernate 集成 示例和struts 2 hello world 示例。在本教程中,我将讨论在将 spring 框架与 struts 与 hibernate 结合使用时要牢记的所有要点。另外,请注意,本教程使用了其他次要但重要的概念,例如日志记录、TLD 的使用和事​​务,这些概念也集成在本教程中。所以记得也要检查他们的详细信息。

在本教程中,我正在构建具有简单功能(如全部获取、添加和删除)的员工管理屏幕。它看起来像这样:

我将按以下步骤讨论集成过程:

1) Integration Overview 
2) Spring + Struts Integration
3) Spring + Hibernate Integration
4) Other Integrated Functionalities
    a) Log4j
    b) TLDs
    c) Transactions
5) Important Points to Keep Remember
6) Database Schema Used in Tutorial
7) Download Sourcecode

1) 集成概述

在进入集成细节之前,让我们首先确定为什么我们需要此集成。与 Struts 一样,Spring 也可以充当 MVC 实现。这两种框架都有其优点和缺点,但仍有许多人会同意 Spring 更好并提供更广泛的功能。对我来说,只有两种情况需要本教程中提供的信息:

i) 您有一个用 struts 编写的旧应用程序,并且想使用 spring 将应用程序的功能提高很多倍。
ii) 您真的想自己学习它原因。

否则我不知道为什么有人会选择 struts 而不是 spring。如果您知道其他一些好的理由,请与我们所有人分享。那挺棒的。

继续,在本教程中,我将 Action 管理从 Struts 委托给 Spring。这种委托的原因是,Action 类在由 spring 上下文实例化时,可以使用 spring 在其自己的 MVC 实现中为其控制器类提供的所有其他功能。因此,您可以获得所有 spring 功能以及 struts Action 类以具有控制器逻辑,包括它的 ActionForm 概念。

2)Spring+Struts整合

这是核心逻辑,从在 web.xml 中注册 ContextLoaderListenerStrutsPrepareAndExecuteFilter 开始。 ContextLoaderListener 采用初始化参数 contextConfigLocation 并负责设置和启动 Spring WebApplicationContext。现在 struts 将在 spring 相关服务中利用这个上下文,特别是在 dependency injection 中。

StrutsPrepareAndExecuteFilter 在类路径中查找 struts.xml 文件并配置 strut 的特定内容,例如 Action 映射、全局转发和 struts 中定义的其他内容。 xml 文件。

web.xml

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

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

			<taglib-location>/WEB-INF/struts-nested.tld</taglib-location>
		</taglib>
	</jsp-config>
</web-app>

在第二步中,您将在 struts.xml 文件中拥有您的操作映射,如下所示:

struts.xml

<?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>
    <!-- devMode is helpful when you want some extra logs for debugging -->
    <constant name="struts.devMode" value="false" />
    <!-- Global message resource; 
    	 Otherwise you will have seperate message resource for each Action 
    -->
    <constant name="struts.custom.i18n.resources" value="messages" /> 
    <!-- 
    	This is important if you are planning to have slashes in Action URLs
    	e.g. In this demo, employee is deleted using URL /delete/10
    	This this is set to false; then struts will try to find mapping for 
    	URL "/10" instaed of "/delete/10"
     -->
    <constant name="struts.enable.SlashesInActionNames" value="true"/>
     
    <!-- Normal Action mappings are defined here -->
	<package name="default" namespace="" extends="struts-default">
	    <!-- Two things to Notice: 
	    	 1) class is set to 'editEmployeeAction' which is bean defined by Spring context
	    	 2) We have given the method to be called here as well;
	   	-->
		<action name="list" class="editEmployeeAction" method="listEmployees">
			<result>/view/editEmployeeList.jsp</result>
		</action>
		<action name="add" class="editEmployeeAction" method="addEmployee">
			<result type="redirect">/list</result>
		</action>
		<action name="delete/*" class="editEmployeeAction" method="deleteEmployee">
		    <param name="employee.id">{1}</param>
			<result type="redirect">/list</result>
		</action>
		<action name="*" class="editEmployeeAction" method="listEmployees">
		  <result>/view/editEmployeeList.jsp</result>
		</action> 
	</package>
	
</struts>
在 strut 的单独应用程序中,我们将拥有完整的 Action 类,其包信息位于“类”属性中。这里我们将类名命名为 editEmployeeAction。它在哪里定义?我们将要求 Spring 为我们查找。

Spring 上下文文件 beans.xml 是典型的 spring 独立上下文文件,具有 Web 应用程序工作所需的所有内容,包括 struts 正在寻找的 bean 定义 editEmployeeAction

beans.xml

<?xml  version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

        http://www.springframework.org/schema/util/ http://www.springframework.org/schema/util/spring-util.xsd">
    
    <!-- This bean has been referred fron struts.xml file; So type it correctly; -->
    <!-- Make scope prototype; This is really important. -->
    <bean name="editEmployeeAction" class="com.cundage.controller.EditEmployeeAction" scope="prototype">
	     <property name="employeeManager">
	        <ref bean="employeeManager"/>
	     </property>
    </bean>
    
    <!-- These beans are injected automatically by spring context -->
    <bean id="employeeDAO" class="com.cundage.dao.EmployeeDaoImpl">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
    
    <bean id="employeeManager" class="com.cundage.service.EmployeeManagerImpl">
        <property name="employeeDAO" ref="employeeDAO"/>
    </bean>
    
    <!-- Configure jdbc.properties -->
    <bean id="propertyConfigurer"
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
        p:location="/WEB-INF/jdbc.properties" />
 
    <!-- Data Source configuration -->
    <bean id="dataSource"
        class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"
        p:driverClassName="${jdbc.driverClassName}"
        p:url="${jdbc.databaseurl}" p:username="${jdbc.username}"
        p:password="${jdbc.password}" />
 
	<!-- Configure hibernate session factory -->    
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation">
            <value>classpath:hibernate.cfg.xml</value>
        </property>
        <property name="configurationClass">
            <value>org.hibernate.cfg.AnnotationConfiguration</value>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${jdbc.dialect}</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
    </bean>
    <!-- Run SQL queries in transactions -->
    <tx:annotation-driven />
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
    
</beans>

这就是我们将 struts 与 spring 集成 框架所需要做的全部工作。现在你的动作类看起来像这样:

EditEmployeeAction.java

package com.cundage.controller;

import java.util.List;

import org.apache.log4j.Logger;

import com.cundage.entity.EmployeeEntity;
import com.cundage.service.EmployeeManager;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.Preparable;

public class EditEmployeeAction extends ActionSupport implements Preparable	
{
	private static final long serialVersionUID = 1L;
	
	//Logger configured using log4j
	private static final Logger logger = Logger.getLogger(EditEmployeeAction.class);
	
	//List of employees; Setter and Getter are below
	private List<EmployeeEntity> employees;
	
	//Employee object to be added; Setter and Getter are below
	private EmployeeEntity employee;
	
	//Employee manager injected by spring context; This is cool !!
	private EmployeeManager employeeManager;

	//This method return list of employees in database
	public String listEmployees() {
		logger.info("listEmployees method called");
		employees = employeeManager.getAllEmployees();
		return SUCCESS;
	}

	//This method will be called when a employee object is added
	public String addEmployee() {
		logger.info("addEmployee method called");
		employeeManager.addEmployee(employee);
		return SUCCESS;
	}

	//Deletes a employee by it's id passed in path parameter
	public String deleteEmployee() {
		logger.info("deleteEmployee method called");
		employeeManager.deleteEmployee(employee.getId());
		return SUCCESS;
	}
	
	//This method will be called before any of Action method is invoked;
	//So some pre-processing if required.
	@Override
	public void prepare() throws Exception {
		employee = null;
	}

	//Getters and Setters hidden
}

Spring 还将 DAO 引用注入到 Manager 类。

EmployeeManagerImpl.java

package com.cundage.service;

import java.util.List;

import org.springframework.transaction.annotation.Transactional;

import com.cundage.dao.EmployeeDAO;
import com.cundage.entity.EmployeeEntity;

public class EmployeeManagerImpl implements EmployeeManager 
{
	//Employee dao injected by Spring context
    private EmployeeDAO employeeDAO;
	
	//This method will be called when a employee object is added
	@Override
	@Transactional
	public void addEmployee(EmployeeEntity employee) {
		employeeDAO.addEmployee(employee);
	}
	
	//This method return list of employees in database
	@Override
	@Transactional
	public List<EmployeeEntity> getAllEmployees() {
		return employeeDAO.getAllEmployees();
	}
	//Deletes a employee by it's id
	@Override
	@Transactional
	public void deleteEmployee(Integer employeeId) {
		employeeDAO.deleteEmployee(employeeId);
	}
	
	//This setter will be used by Spring context to inject the dao's instance
	public void setEmployeeDAO(EmployeeDAO employeeDAO) {
		this.employeeDAO = employeeDAO;
	}
}

3)Spring+Hibernate集成

现在我们必须将休眠集成到应用程序中。最好的地方是使用 Spring 的广泛功能进行集成,以使用依赖注入的出色使用来与不同的 ORM 一起工作。

上面的 beans.xml 文件中已经给出了 spring 所需的 hibernate 依赖项。您需要的其他文件是:

休眠.cfg.xml

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
 
<hibernate-configuration>
    <session-factory>
        <mapping class="com.cundage.entity.EmployeeEntity" />
    </session-factory>
</hibernate-configuration>

jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.dialect=org.hibernate.dialect.MySQLDialect
jdbc.databaseurl=jdbc:mysql://127.0.0.1:3306/test
jdbc.username=root
jdbc.password=password

EmployeeDaoImpl.java

package com.cundage.dao;

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;

import com.cundage.entity.EmployeeEntity;

@Repository
public class EmployeeDaoImpl implements EmployeeDAO  
{
	//Session factory injected by spring context
    private SessionFactory sessionFactory;
	
    //This method will be called when a employee object is added
	@Override
	public void addEmployee(EmployeeEntity employee) {
		this.sessionFactory.getCurrentSession().save(employee);
	}

	//This method return list of employees in database
	@SuppressWarnings("unchecked")
	@Override
	public List<EmployeeEntity> getAllEmployees() {
		return this.sessionFactory.getCurrentSession().createQuery("from EmployeeEntity").list();
	}

	//Deletes a employee by it's id
	@Override
	public void deleteEmployee(Integer employeeId) {
		EmployeeEntity employee = (EmployeeEntity) sessionFactory.getCurrentSession()
										.load(EmployeeEntity.class, employeeId);
        if (null != employee) {
        	this.sessionFactory.getCurrentSession().delete(employee);
        }
	}

	//This setter will be used by Spring context to inject the sessionFactory instance
	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}
}

作为参考,EmployeeEntity 类如下所示:

EmployeeEntity.java

package com.cundage.entity;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="EMPLOYEE")
public class EmployeeEntity {
     
    @Id
    @Column(name="ID")
    @GeneratedValue
    private Integer id;
     
    @Column(name="FIRSTNAME")
    private String firstname;
 
    @Column(name="LASTNAME")
    private String lastname;
 
    @Column(name="EMAIL")
    private String email;
     
    @Column(name="TELEPHONE")
    private String telephone;
     
    //Setters and Getters
}

4) 其他集成功能

除了 struts + spring + hibernate 之外,我们还使用了以下组件来构建应用程序。

一)日志4j

Spring 通过扫描类路径中的 log4j 自动配置日志记录。我们使用 pom.xml 文件添加了 log4j 依赖项。现在您只需在类路径中放置一个 log4j.xml 或 log4j.properties 文件。

log4j.properties

log4j.rootLogger=info, stdout, R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=c:/log/demo.log
log4j.appender.R.MaxFileSize=100KB
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

b) 顶级域名

如果您查看 web.xml 文件,我们会在其中包含一些 TLD。我们可以随时在视图层中使用它们,如下所示:

编辑员工列表.jsp

<%@ taglib prefix="s" uri="/struts-tags"%> 
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>
<head>
    <title>Spring-4 + Struts-3 + Hibernate Integration Demo</title>
    <style>
	table.list
	{
		border-collapse:collapse;
		width: 40%;
	}
	table.list, table.list td, table.list th
	{
		border:1px solid gray;
		padding: 5px;
	}
	</style>
</head>
<body>
 
<h2>Spring-4 + Struts-3 + Hibernate Integration Demo</h2>
 
<s:form method="post" action="add">
    <table>
	    <tr>
	        <td><s:textfield key="label.firstname" name="employee.firstname"/></td> 
	    </tr>
	    <tr>
	        <td><s:textfield key="label.lastname" name="employee.lastname"/></td>
	    </tr>
	    <tr>
	        <td><s:textfield key="label.email" name="employee.email"/></td>
	    </tr>
	    <tr>
	        <td><s:textfield key="label.telephone" name="employee.telephone"/></td>
	    </tr>
	    <tr>
	        <td>
	        	<s:submit key="label.add"></s:submit>
	        </td>
	    </tr>
	</table> 
</s:form>
 
     
<h3>Employees</h3>
<c:if  test="${!empty employees}">
	<table class="list">
		<tr>
		    <th align="left">Name</th>
		    <th align="left">Email</th>
		    <th align="left">Telephone</th>
		    <th align="left">Actions</th>
		</tr>
		<c:forEach items="${employees}" var="emp">
		    <tr>
		        <td>${emp.lastname}, ${emp.firstname} </td>
		        <td>${emp.email}</td>
		        <td>${emp.telephone}</td>
		        <td><a href="delete/${emp.id}">delete</a></td>
		    </tr>
		</c:forEach>
	</table>
</c:if>
 
</body>
</html>

c) 交易

EmployeeManagerImpl.java 在getAllEmployees() 和deleteEmployee() 等方法中使用注解@Transactional。这实质上是在单个事务中运行在此方法下执行的所有数据库查询。您像这样在 beans.xml 上下文文件中声明事务依赖性。

<!-- Run SQL queries in transactions -->
<tx:annotation-driven />

<bean id="transactionManager"
	class="org.springframework.orm.hibernate3.HibernateTransactionManager">
	<property name="sessionFactory" ref="sessionFactory" />
</bean>

5)要记住的要点

a) 如果运行时无法在 lib 文件夹中找到类,则将项目依赖项中的 jar 文件添加到项目部署程序集中

b) 使在bean.xml 中定义的Action 类的作用域为“原型”。 Spring 提供的 bean 的默认范围是单例,并且必须为每个请求创建新的 struts Action 类,因为它包含用户会话特定数据。为了适应两者,将 Action 类 bean 标记为原型。

c)
在运行此应用程序之前不要忘记设置数据库。如果设置不正确,它会导致你出现几个异常。

d) 此外,请在项目运行时依赖项中包含 struts2-spring-plugin

6) 教程中使用的数据库模式

下表已在名为“test”的数据库中的 MySQL 中创建。

CREATE TABLE EMPLOYEE
(
    ID          INT PRIMARY KEY AUTO_INCREMENT,
    FIRSTNAME   VARCHAR(30),
    LASTNAME    VARCHAR(30),
    TELEPHONE   VARCHAR(15),
    EMAIL       VARCHAR(30),
    CREATED     TIMESTAMP DEFAULT NOW()
);

如果您打算自己构建应用程序,那么下面给出的此应用程序中使用的直接结构 将对您有所帮助。
