首先匯入相關包：spring-beans-3.0.4.RELEASE.jar（org.springframework.beans.factory.annotation.Autowired用來注入bean）、spring-context-3.0.4.RELEASE.jar（org.springframework.stereotype.Componet 、Service、Repository等用來定義bean）。

其次需要新增相關配置：applicationContext.xml

<?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:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <description>Spring公共配置 </description> <!-- 配置資料來源 --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/> <property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:cui"/> <property name="username" value="cui"/> <property name="password" value="cui"/> </bean> <!-- 配置sessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop> <prop key="hibernate.show_sql">true</prop> </props> </property> <property name="packagesToScan"> <list> <value>com.entity</value> </list> </property> </bean> <!-- 事務管理 --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 使用annotation自動注入bean,並啟動相關處理註解的程序 --> <context:component-scan base-package="com"> <context:include-filter type="regex" expression="com/.dao.*"/> <!-- 正則表示式必須格式正確，否則無效。以下是無效的示例 <context:exclude-filter type="regex" expression="/.service/..*"/> <context:exclude-filter type="regex" expression="com/.service*"/> <context:exclude-filter type="regex" expression=".service*"/> --> <!-- 正確格式:從base-package開始 <context:exclude-filter type="regex" expression="com/.service.*"/> <context:exclude-filter type="regex" expression="com/.service/..*"/> --> </context:component-scan> </beans>

web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" 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"> <display-name>mytest</display-name> <!-- 指定spring配置檔案的位置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:/applicationContext.xml</param-value> </context-param> <!-- Struts 2 --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> <init-param> <param-name>actionPackages</param-name> <param-value>com.action</param-value> </init-param> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 自動載入applicationContext --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>

使用Hibernate JPA定義User類：

package com.entity; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table(name = "s_user") public class User { private Long id; private String username; private String password; @Id @GeneratedValue(strategy = GenerationType.AUTO) public Long getId() { return id; } public void setId(Long id) { this.id = id; } @Column(name = "name") public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } @Column(name = "pwd") public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }

Dao層：

package com.dao; import com.entity.User; public interface UserDao { public void save(User user); } package com.dao.Impl; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.hibernate.SessionFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.orm.hibernate3.HibernateTemplate; import org.springframework.stereotype.Repository; import com.dao.UserDao; import com.entity.User; @Repository("userDao") public class UserDaoImpl implements UserDao { private HibernateTemplate template; private Log log = LogFactory.getLog(UserDaoImpl.class); //使用構造子注入自動注入sessionFactory @Autowired public UserDaoImpl(SessionFactory sessionFactory) { this.template = new HibernateTemplate(sessionFactory); } public void save(User user) { template.save(user); log.debug("save user:" + user.getUsername()); } }

Service層：

package com.service; import com.entity.User; public interface UserManager { public void add(User user); } package com.service.Impl; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.dao.UserDao; import com.entity.User; import com.service.UserManager; @Service("userManager") public class UserManagerImpl implements UserManager { //自動注入userDao，也可以使用@Resource @Autowired private UserDao userDao; private Log log = LogFactory.getLog(UserManagerImpl.class); public void add(User user) { userDao.save(user); log.debug("add User:" + user.getUsername()); } }

Action：

package com.action.convention; import org.apache.struts2.convention.annotation.Result; import org.springframework.beans.factory.annotation.Autowired; import com.entity.User; import com.opensymphony.xwork2.ActionSupport; import com.service.UserManager; @Result(name = "success", location = "hello.jsp") public class UserAction extends ActionSupport { private static final long serialVersionUID = 1L; @Autowired private UserManager userManager; public String execute() { User user = new User(); user.setUsername("cuihaiyang"); user.setPassword("abcd"); userManager.add(user); return SUCCESS; } }

除錯資訊如下：

Hibernate: select hibernate_sequence.nextval from dual
Hibernate: insert into s_user (pwd, name, id) values (?, ?, ?)
2011-03-10 19:44:25,296 [http-8080-1] DEBUG [com.dao.Impl.UserDaoImpl] - save user:cuihaiyang
2011-03-10 19:44:25,296 [http-8080-1] DEBUG [com.service.Impl.UserManagerImpl] - add User:cuihaiyang
