1:新建maven-archetupe-webapp項目
2:web.xml配置文件如下
<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <!-- springmvc 上下文監聽器 ContextLoaderListener --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/*.xml</param-value> </context-param> <!-- springmvc 上下文監聽器 ContextLoaderListener--> <!-- struts過濾器 --> <filter> <filter-name>SSH</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>SSH</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- struts過濾器 --> <!-- 過濾器 --> <filter> <filter-name>encodingFilter</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>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 過濾器 --> <display-name>spring-ssh</display-name> </web-app>
3：struts.xml配置如下
<?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> <!-- 請求參數的編碼方式--> <constant name="struts.i18n.encoding" value="UTF-8"/> <!-- 指定被struts2處理的請求後綴類型。多個用逗號隔開--> <constant name="struts.action.extension" value="action,do,htm,html"/> <!-- 當struts.xml改動後，是否重新加載。默認值爲false(生產環境下使用),開發階段最好打開 --> <constant name="struts.configuration.xml.reload" value="true"/> <!-- 是否使用struts的開發模式。開發模式會有更多的調試信息。默認值爲false(生產環境下使用),開發階段最好打開 --> <constant name="struts.devMode" value="false"/> <!-- 設置瀏覽器是否緩存靜態內容。默認值爲true(生產環境下使用),開發階段最好關閉 --> <constant name="struts.serve.static.browserCache" value="false" /> <!-- 指定由spring負責action對象的創建 --> <constant name="struts.objectFactory" value="spring" /> <!-- 不用註解模式 <package name="book" namespace="/" extends="struts-default"> <action name="login" class="struts2.LoginAction" method="login"> <result name="success">../views/login.jsp</result> </action> </package> --> <!-- 是否開啓動態方法調用--> <constant name="struts.enable.DynamicMethodInvocation" value="false"/> </struts>
4：spring.xml代碼如下
<?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:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd" default-lazy-init="true"> <mvc:annotation-driven /> <context:component-scan base-package="com.xiaoji.ssh"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> <context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/> </context:component-scan> <context:property-placeholder location="classpath:property/jdbc.properties"/> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="${database.driverClassName}" /> <property name="jdbcUrl" value="${database.url}" /> <property name="user" value="${database.username}" /> <property name="password" value="${database.password}" /> <!--連接池中保留的最大連接數。默認值: 15 --> <property name="maxPoolSize" value="20"/> <!-- 連接池中保留的最小連接數，默認爲：3--> <property name="minPoolSize" value="2"/> <!-- 初始化連接池中的連接數，取值應在minPoolSize與maxPoolSize之間，默認爲3--> <property name="initialPoolSize" value="2"/> <!--最大空閒時間，60秒內未使用則連接被丟棄。若爲0則永不丟棄。默認值: 0 --> <property name="maxIdleTime" value="60"/> <!--當連接池中的連接耗盡的時候c3p0一次同時獲取的連接數。默認值: 3 --> <property name="acquireIncrement" value="2"/> <!--定義在從數據庫獲取新連接失敗後重復嘗試的次數。默認值: 30 ；小於等於0表示無限次--> <property name="acquireRetryAttempts" value="0"/> <!--重新嘗試的時間間隔，默認爲：1000毫秒--> <property name="acquireRetryDelay" value="1000" /> <!--如果爲false，則獲取連接失敗將會引起所有等待連接池來獲取連接的線程拋出異常，但是數據源仍有效保留，並在下次調用getConnection()的時候繼續嘗試獲取連接。如果設爲true，那麼在嘗試獲取連接失敗後該數據源將申明已斷開並永久關閉。默認: false--> <property name="breakAfterAcquireFailure" value="false"/> </bean> <!--定義Hibernate的SessionFactory --> <!-- SessionFactory使用的數據源爲上面的數據源 --> <!-- 指定了Hibernate的映射文件和配置信息 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="annotatedClasses"> <list> <value>com.xiaoji.ssh.entity.Book</value> </list> </property> <property name="annotatedPackages"> <list> <value>com.xiaoji.ssh.entity</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="show_sql">true</prop> <prop key="hibernate.jdbc.batch_size">20</prop> </props> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- REQUIRED：支持當前事務，如果當前沒有事務，就新建一個事務。這是最常見的選擇。 SUPPORTS：支持當前事務，如果當前沒有事務，就以非事務方式執行。 MANDATORY：支持當前事務，如果當前沒有事務，就拋出異常。 REQUIRES_NEW：新建事務，如果當前存在事務，把當前事務掛起。 NOT_SUPPORTED：以非事務方式執行操作，如果當前存在事務，就把當前事務掛起。 NEVER：以非事務方式執行，如果當前存在事務，則拋出異常。 NESTED：支持當前事務，如果當前事務存在，則執行一個嵌套事務，如果當前沒有事務，就新建一個事務。 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <!-- <tx:method name="*" propagation="true" />--> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="allManagerMethod" expression="execution(* com.xiaoji.ssh.service.*.*(..))" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="allManagerMethod" /> </aop:config> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory" /> </bean> </beans>
5:jdbc.properties代碼如下
#c3p0jdbc
database.driverClassName=com.mysql.jdbc.Driver
database.url=jdbc:mysql://127.0.0.1:3306/springtest?useUnicode=true&characterEncoding=UTF-8
database.username=root
database.password=root
6:sql建表
CREATE TABLE `book` ( `book_id` int(11) NOT NULL auto_increment, `name` varchar(50) default NULL, `description` varchar(100) default NULL, PRIMARY KEY (`book_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
7:創建entity,使用hibernate-jpa註解實現數據層
package com.xiaoji.ssh.entity; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import static javax.persistence.GenerationType.IDENTITY; import javax.persistence.Id; import javax.persistence.Table; /** * Book entity. @author MyEclipse Persistence Tools */ @Entity @Table(name = "book", catalog = "springtest") public class Book implements java.io.Serializable { // Fields private Integer bookId; private String name; private String description; // Constructors /** default constructor */ public Book() { } /** full constructor */ public Book(String name, String description) { this.name = name; this.description = description; } // Property accessors @Id @GeneratedValue(strategy = IDENTITY) @Column(name = "book_id", unique = true, nullable = false) public Integer getBookId() { return this.bookId; } public void setBookId(Integer bookId) { this.bookId = bookId; } @Column(name = "name", length = 50) public String getName() { return this.name; } public void setName(String name) { this.name = name; } @Column(name = "description", length = 100) public String getDescription() { return this.description; } public void setDescription(String description) { this.description = description; } }
8:創建dao
接口：
package com.xiaoji.ssh.dao; import java.util.List; import com.xiaoji.ssh.entity.Book; public interface BookDao{ public List<Book> getBookList(); public void saveBook(Book book); public void deleteBook(int bookId); public void updateBook(Book book); public Book getBookByBookId(int bookId); }
實現類：
package com.xiaoji.ssh.dao.impl; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.orm.hibernate3.HibernateTemplate; import org.springframework.stereotype.Repository; import com.xiaoji.ssh.dao.BookDao; import com.xiaoji.ssh.entity.Book; @Repository public class BookDaoImpl implements BookDao { private HibernateTemplate hibernateTemplate; public HibernateTemplate getHibernateTemplate() { return hibernateTemplate; } @Autowired public void setHibernateTemplate(HibernateTemplate hibernateTemplate) { this.hibernateTemplate = hibernateTemplate; } public List<Book> getBookList() { List<Book> list = (List<Book>)getHibernateTemplate().find("From Book"); return list; } public void saveBook(Book book) { getHibernateTemplate().save(book); } public void deleteBook(int bookId) { getHibernateTemplate().delete(getBookByBookId(bookId)); } public void updateBook(Book book) { // TODO Auto-generated method stub getHibernateTemplate().update(book); } public Book getBookByBookId(int bookId) { Book book = (Book)getHibernateTemplate().get(Book.class, bookId); return book; } }
9:創建service
接口：
package com.xiaoji.ssh.service; import java.util.List; import com.xiaoji.ssh.entity.Book; public interface BookService { public List<Book> getBookList(); public void saveBook(Book book); public void deleteBook(int bookId); public void updateBook(Book book); public Book getBookByBookId(int bookId); }
實現類：
package com.xiaoji.ssh.service.impl; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.xiaoji.ssh.dao.BookDao; import com.xiaoji.ssh.entity.Book; import com.xiaoji.ssh.service.BookService; @Service public class BookServiceImpl implements BookService{ @Autowired private BookDao bookDao; @Override public List<Book> getBookList() { return bookDao.getBookList(); } @Override public void saveBook(Book book) { bookDao.saveBook(book); } @Override public void deleteBook(int bookId) { bookDao.deleteBook(bookId); } @Override public void updateBook(Book book) { bookDao.updateBook(book); } @Override public Book getBookByBookId(int bookId) { return bookDao.getBookByBookId(bookId); } }
10:action類源碼如下
package com.xiaoji.ssh.action; import org.apache.struts2.convention.annotation.Action; import org.apache.struts2.convention.annotation.ExceptionMapping; import org.apache.struts2.convention.annotation.ExceptionMappings; import org.apache.struts2.convention.annotation.Namespace; import org.apache.struts2.convention.annotation.ParentPackage; import org.apache.struts2.convention.annotation.Result; import org.apache.struts2.convention.annotation.Results; import com.opensymphony.xwork2.ActionSupport; /** * Struts2基於註解的Action配置 * ParentPackage 繼承父包 * Namespace命名空間 * Results跳轉頁面 * Action訪問方法 */ @ParentPackage("struts-default") @Namespace("/book") @Results( { @Result(name = "success", location = "/views/main.jsp"), @Result(name = "error", location = "/views/error.jsp") }) @ExceptionMappings( { @ExceptionMapping(exception = "java.lange.RuntimeException", result = "error") }) public class BookAction extends ActionSupport{ private String username; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } @Action(value="test") public String test(){ this.setUsername("strutsTest"); return SUCCESS; } @Action(value = "bookView", results = { @Result(name = "success", location = "/index.jsp") }) public String bookView(){ return SUCCESS; } }
11:pom.xml源碼

12:忘記了還有個測試類
package com.xiaoji.ssh.dao; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import com.xiaoji.ssh.entity.Book; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"classpath:spring/*.xml" }) public class BookDaoTest { @Autowired private BookDao bookDao; @Test public void testGetBookList(){ System.out.println("xiaoji"); } @Test public void testSaveBookList(){ System.out.println(bookDao.getBookList()); } @Test public void testUpdateBookList(){ Book book = new Book(); book.setName("ssh3"); book.setDescription("ssh3"); bookDao.saveBook(book); System.out.println("ok"); } }
註解：在src/main/webapp下面建立個view目錄，並新建main.jsp和error.jsp.如果覺的此文對你有幫助，請回復一下鼓勵下我，以後我會發布更多類似文章。
下面貼上目錄結構圖：
