Struts+Spring+Hibernate注解零配置整合
个人努力,请不要转载,收藏就好
本工程为Maven工程,可以下载maven-eclipse插件进行项目导入
如果在eclipse中用WTP插件配置Tomcat运行,需要把maven项目转成Eclipse工程
请下载附件,解压后在工程文件夹运行以下maven命令:
以下是工程的pom.xml文件,用来管理所有依赖的jar包:
以下是web.xml,已经配置了Struts和Spring:
Spring主配置文件applicationContext.xml:
Struts用默认配置,因此不放置struts.xml
Hibernate的Spring配置hibernate.cfg.xml文件如下:
以下这句用来指明,数据事务用Spring的声明式事务,即使用@Transactional注解
数据库的属性配置文件hibernate.properties如下:
logback日志配置文件logback.xml如下:
以上是所有的配置文件。
JSP代码不再贴出,请下载附件。
以下是java程序代码
用于接收请求的Struts的Action类:UserAction.java
处理逻辑的Service:UserService.java
因为Service只是处理增删改查,没有验证数据,所以比较简单,值得注意的是,@Transactional事务注解只能写在Service层,不能写在Action层,不然会出错,估计是对Spring3对Struts2支持的不太好
Hibernate的PO对象:User.java
不再需要用XML进行表和实体类的映射了
数据存储层通用DAO接口定义:GeneralDao.java
DAO的实现类:GeneralDAOImpl.java
这就是整个搭建框架,是一个内核。在应用时,可以配置freemarker之类的其余框架进来,用于实际开发
纯注解形式的代码有助于代码开发和管理,很代码更整洁,测试代码也可以用注解形式,也方便测试。因为注解形式把配置和代码放在一起,维护比较方便,减少了配置和代码的同步,也减少了代码量,使BUG数降低。个人推荐使用注解形式的配置
注解形式的代码,可以算一程契约形式的编程,只关心我想做什么,不关心怎么做,代码的耦合比较小,模块化比较强。JDK7也在主推模块化,这两个方向是以后的发展趋势

以下是web.xml,已经配置了Struts和Spring:
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- 加载struts2核心 --> <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> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>GBK</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>*</url-pattern> </filter-mapping> <!-- 指明spring配置文件在何处 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:applicationContext.xml</param-value> </context-param> <!-- 加载spring配置文件applicationContext.xml --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
Spring主配置文件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: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/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <context:annotation-config /> <context:component-scan base-package="com.tianlihu.projects.ssh" /> <context:property-placeholder location="classpath:hibernate.properties"/> <import resource="classpath:hibernate.cfg.xml"/> </beans>
Struts用默认配置,因此不放置struts.xml
Hibernate的Spring配置hibernate.cfg.xml文件如下:
<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- C3P0 数据源 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="${hibernate.connection.driver_class}" /> <property name="jdbcUrl" value="${hibernate.connection.url}" /> <property name="user" value="${hibernate.connection.username}" /> <property name="password" value="${hibernate.connection.password}" /> <property name="initialPoolSize" value="${hibernate.connection.initialPoolSize}" /> <property name="minPoolSize" value="${hibernate.connection.minPoolSize}" /> <property name="maxPoolSize" value="${hibernate.connection.maxPoolSize}" /> <property name="preferredTestQuery" value="select 1 from dual " /> </bean> <!-- SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="packagesToScan" value="com.tianlihu.projects.ssh.*.po" /> <property name="useTransactionAwareDataSource" value="true" /> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <prop key="hibernate.format_sql">${hibernate.format_sql}</prop> <prop key="hibernate.temp.use_jdbc_metadata_defaults">${hibernate.temp.use_jdbc_metadata_defaults}</prop> <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> <prop key="hibernate.cache.provider_class">${hibernate.cache.provider_class}</prop> <prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop> <prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop> <prop key="hibernate.connection.autocommit">false</prop> <prop key="hibernate.current_session_context_class">thread</prop> </props> </property> </bean> <!-- 配置事务管理 --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <aop:aspectj-autoproxy /> <tx:annotation-driven /> </beans>
以下这句用来指明,数据事务用Spring的声明式事务,即使用@Transactional注解
<tx:annotation-driven />
数据库的属性配置文件hibernate.properties如下:
## hibernate hibernate.dialect=org.hibernate.dialect.MySQLDialect hibernate.show_sql=true hibernate.format_sql=true hibernate.hbm2ddl.auto=create-drop hibernate.temp.use_jdbc_metadata_defaults=false ## hibernate cache hibernate.cache.provider_class=org.hibernate.cache.EhCacheProvider hibernate.cache.use_query_cache=false hibernate.cache.use_second_level_cache=true ## C3P0 configuration hibernate.connection.driver_class=com.mysql.jdbc.Driver hibernate.connection.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=GBK hibernate.connection.username=root hibernate.connection.password=root hibernate.connection.initialPoolSize=1 hibernate.connection.minPoolSize=1 hibernate.connection.maxPoolSize=3
logback日志配置文件logback.xml如下:

以上是所有的配置文件。
JSP代码不再贴出,请下载附件。
以下是java程序代码
用于接收请求的Struts的Action类:UserAction.java
package com.tianlihu.projects.ssh.account.action; import java.util.List; import org.apache.struts2.convention.annotation.Action; import org.apache.struts2.convention.annotation.Namespace; import org.apache.struts2.convention.annotation.ParentPackage; import org.apache.struts2.convention.annotation.Result; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import com.tianlihu.projects.ssh.account.po.User; import com.tianlihu.projects.ssh.account.service.UserService; @ParentPackage("struts-default") @Namespace("/account") @Component public class UserAction { @Autowired private UserService userService; private List<User> users; private String userId; private String name; private String password; private String age; private String message; @Action(value = "createUser", results = { @Result(name = "success", location = "/WEB-INF/userForm.jsp") }) public String createUser() { message = "创建用户"; return "success"; } @Action(value = "create", results = { @Result(name = "success", type = "redirect", params = { "encode", "true" }, location = "fetchUsers?message=${message}") }) public String create() { User user = getUser(); userService.createUser(user); message = "创建用户'" + userId + "'成功"; return "success"; } @Action(value = "updateUser", results = { @Result(name = "success", location = "/WEB-INF/userForm.jsp") }) public String updateUser() { User user = userService.findByUserId(userId); name = user.getName(); password = user.getPassword(); age = String.valueOf(user.getAge()); message = "修改用户'" + userId + "'"; return "success"; } @Action(value = "update", results = { @Result(name = "success", type = "redirect", params = { "encode", "true" }, location = "fetchUsers?message=${message}") }) public String update() { User user = getUser(); userService.updateUser(user); message = "修改用户'" + userId + "'成功"; return "success"; } @Action(value = "delete", results = { @Result(name = "success", type = "redirect", params = { "encode", "true" }, location = "fetchUsers?message=${message}") }) public String deleteUser() { userService.deleteUser(userId); message = "删除用户'" + userId + "'成功"; return "success"; } @Action(value = "fetchUsers", results = { @Result(name = "success", location = "/WEB-INF/users.jsp") }) public String fetchUsers() { users = userService.findAll(); return "success"; } private User getUser() { User user = new User(); user.setUserId(userId); user.setName(name); user.setPassword(password); user.setAge(Integer.parseInt(age)); return user; } public String getUserId() { return userId; } public void setUserId(String userId) { this.userId = userId; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getAge() { return age; } public void setAge(String age) { this.age = age; } public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } public List<User> getUsers() { return users; } public void setUsers(List<User> users) { this.users = users; } }
处理逻辑的Service:UserService.java
因为Service只是处理增删改查,没有验证数据,所以比较简单,值得注意的是,@Transactional事务注解只能写在Service层,不能写在Action层,不然会出错,估计是对Spring3对Struts2支持的不太好
package com.tianlihu.projects.ssh.account.service; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import com.tianlihu.projects.ssh.account.dao.GeneralDao; import com.tianlihu.projects.ssh.account.po.User; @Service public class UserService { @Autowired private GeneralDao generalDao; public User findByUserId(String userId) { return generalDao.findById(User.class, userId); } public List<User> findAll() { return generalDao.findAll(User.class); } @Transactional public void createUser(User user) { generalDao.save(user); } @Transactional public void updateUser(User user) { generalDao.update(user); } @Transactional public void deleteUser(String userId) { generalDao.deleteById(User.class, userId); } @Transactional public void deleteUser(User user) { generalDao.delete(user); } }
Hibernate的PO对象:User.java
不再需要用XML进行表和实体类的映射了
package com.tianlihu.projects.ssh.account.po; import java.io.Serializable; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Id; @Entity(name = "AC_USER") public class User implements Serializable { private static final long serialVersionUID = -1376216905288707683L; @Id @Column(name = "USER_ID", length =50, nullable = false) private String userId; @Column(name = "NAME", length = 50, nullable = false) private String name; @Column(name = "PASSWORD", length = 50, nullable = false) private String password; @Column(name = "AGE", length = 20, nullable = false) private int age; public String getUserId() { return userId; } public void setUserId(String userId) { this.userId = userId; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }
数据存储层通用DAO接口定义:GeneralDao.java
package com.tianlihu.projects.ssh.account.dao; import java.io.Serializable; import java.util.List; public interface GeneralDao { public <T> T findById(Class<T> type, Serializable id); public <T> List<T> findAll(Class<T> type); public void save(Object... entities); public void update(Object... entities); public void saveOrUpdate(Object entity); public void delete(Object... entities); public void deleteById(Class<?> type, Serializable id); public void refresh(Object... entities); public void flush(); }
DAO的实现类:GeneralDAOImpl.java
package com.tianlihu.projects.ssh.account.dao; import java.io.Serializable; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.orm.hibernate3.HibernateTemplate; import org.springframework.stereotype.Repository; @Repository public class GeneralDAOImpl implements GeneralDao { @Autowired private HibernateTemplate hibernateTemplate; @Override public <T> T findById(Class<T> type, Serializable id) { return hibernateTemplate.get(type, id); } @Override public <T> List<T> findAll(Class<T> type) { return hibernateTemplate.loadAll(type); } @Override public void save(Object... entities) { for (Object entity : entities) { hibernateTemplate.save(entity); } } @Override public void saveOrUpdate(Object entity) { hibernateTemplate.saveOrUpdate(entity); } @Override public void update(Object... entities) { for (Object entity : entities) { hibernateTemplate.update(entity); } } @Override public void delete(Object... entities) { for (Object entity : entities) { if (entity != null) { hibernateTemplate.delete(entity); } } } @Override public void deleteById(Class<?> type, Serializable id) { if (id == null) { return; } Object entity = findById(type, id); if (entity == null) { return; } delete(entity); } @Override public void refresh(Object... entities) { for (Object entity : entities) { hibernateTemplate.refresh(entity); } } @Override public void flush() { hibernateTemplate.flush(); } }
这就是整个搭建框架,是一个内核。在应用时,可以配置freemarker之类的其余框架进来,用于实际开发
纯注解形式的代码有助于代码开发和管理,很代码更整洁,测试代码也可以用注解形式,也方便测试。因为注解形式把配置和代码放在一起,维护比较方便,减少了配置和代码的同步,也减少了代码量,使BUG数降低。个人推荐使用注解形式的配置
注解形式的代码,可以算一程契约形式的编程,只关心我想做什么,不关心怎么做,代码的耦合比较小,模块化比较强。JDK7也在主推模块化,这两个方向是以后的发展趋势
