springmvc+spring4.1.6+hibernate4.3.8调整注解
今天来整合了一下spring,hibernate。
其实在前面S2sh框架整合的学习下,整合这个感觉还是比较轻松的,首先导入的jar包一下少了很多,因为springmvc本来就是spring框架的一部分,只需要将spring-webmvc跟spring-web(这个包之前好像也要加入进去)这些jar包导入进来,其他部分就是spring的一些其他的jar包跟hibernate的一些jar包,这些包的导入在这里就不描述了,可以在****上下载整个测试项目进行查看:http://download.****.net/detail/mjcreator/9526168
另外,在这里还是要说一下,在这个项目中commons-pool跟commons-dbcp这两个包还是不可以少的。
好了,jar包的导入在这里不继续记录了。
接下来帖上原代码以供以后参看吧。
web.xml文件的配置:
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>openSessionInView</filter-name> <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class> </filter> <filter-mapping> <filter-name>openSessionInView</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
applicationContext.xml文件:
<?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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <context:component-scan base-package=" cn.bdx.controller, cn.bdx.dao.impl, cn.bdx.service.impl, cn.bdx.model" /> <!-- springmvc的配置 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/" /> <property name="suffix" value=".jsp" /> </bean> <!-- 读取配置文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value> classpath:jdbc.properties </value> </list> </property> </bean> <!-- 配置数据库驱动 --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="${jdbc.driverClassName}"/> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="annotatedClasses"> <list> <value>cn.bdx.model.User</value> </list> </property> <property name="hibernateProperties"> <props> <!-- 配置时前面最好添加上 'hibernate.' --> <!-- 一个Hibernate Dialect类名允许Hibernate针对特定的关系数据库生成优化的SQL --> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <!-- 输出所有SQL语句到控制台 --> <prop key="hibernate.show_sql">true</prop> <!-- 在log和console中打印出更漂亮的SQL --> <prop key="hibernate.format_sql">true</prop> </props> </property> </bean> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate4.HibernateTemplate"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property> </bean> <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/> </beans>
jdbc.properties文件的配置:
jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url=jdbc\:mysql\://localhost\:3306/item?useUnicode\=true&characterEncoding\=utf-8&autoReconnect\=true jdbc.username=root jdbc.password=123456
好了,到这里配置文件差不多了。
User类:
package cn.bdx.model; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table(name="t_user") public class User { @Id @GeneratedValue(strategy=GenerationType.AUTO) private int id; private String name; private int age; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }
UserController类的代码:
package cn.bdx.controller; import javax.annotation.Resource; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import cn.bdx.model.User; import cn.bdx.service.intf.UserService; @Controller @RequestMapping("/user") public class UserController { @Resource private UserService userService; @RequestMapping("/add") public ModelAndView add(User user,ModelMap model) { this.userService.add(user); System.out.println("add user complete"); return new ModelAndView("index",model); } @RequestMapping("/query") public ModelAndView query(ModelMap model) { this.userService.query(); System.out.println("query user compelte"); return new ModelAndView("index",model); } public UserService getUserService() { return userService; } public void setUserService(UserService userService) { this.userService = userService; } }
UserService接口的代码:
package cn.bdx.service.intf; import java.util.List; import cn.bdx.model.User; public interface UserService { public void add(User user); public List<User> query(); }
UserServiceImpl类的代码:
package cn.bdx.service.impl; import java.util.List; import javax.annotation.Resource; import org.springframework.stereotype.Service; import cn.bdx.dao.intf.UserDao; import cn.bdx.model.User; import cn.bdx.service.intf.UserService; @Service("userService") public class UserServiceImpl implements UserService{ @Resource private UserDao userDao; @Override public void add(User user) { this.userDao.add(user); } @Override public List<User> query() { return this.userDao.query(); } public UserDao getUserDao() { return userDao; } public void setUserDao(UserDao userDao) { this.userDao = userDao; } }
UserDao接口的代码:
package cn.bdx.dao.intf; import java.util.List; import cn.bdx.model.User; public interface UserDao { public void add(User user); public List<User> query(); }
UserDaoImpl类的代码:
package cn.bdx.dao.impl; import java.util.List; import javax.annotation.Resource; import org.springframework.orm.hibernate4.HibernateTemplate; import org.springframework.stereotype.Repository; import org.springframework.transaction.annotation.Transactional; import cn.bdx.dao.intf.UserDao; import cn.bdx.model.User; @Repository("userDao") public class UserDaoImpl implements UserDao{ @Resource private HibernateTemplate hibernateTemplate; @Override @Transactional(readOnly=false) public void add(User user) { this.hibernateTemplate.save(user); } @Override public List<User> query() { List<User> userList = (List<User>)this.hibernateTemplate.find("from User"); System.out.println(userList); return userList; } public HibernateTemplate getHibernateTemplate() { return hibernateTemplate; } public void setHibernateTemplate(HibernateTemplate hibernateTemplate) { this.hibernateTemplate = hibernateTemplate; } }
好了到这里基本上的内容完毕了,接下来只需要部署并启动tomcat,访问http://localhost:8080/spring-hibernate-test/user/query或者http://localhost:8080/spring-hibernate-test/user/add进行测试即可。成功的话会跳转到index.jsp页面上去,并且在控制台有输出内容。
其实做这个项目我就是想看看一个事情,那就是我将springmvc-servlet.xml这个配置文件不要看看能不能行,事实证明是可以的,只是将需要修改几个地方。首先一个修改的地方就是web.xml文件中关于设置springmvc的servlet处:
如果需要springmvc-servlet.xml这个文件,配置的方式如下:注意"param-value"的值。
<servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:*-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
如果不需要这个文件,则需要指定一个其他的xml配置文件来完成springmvc的视图解析器bean的配置,我这里指定的是applicationContext.xml文件,这个web.xml文件关于springmvc的配置如下:注意其中的"param-value"的值。其实看这两个"param-value"的值不难看出,只是将对应xml文件的名称换了而已。
<servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
然后就是springmvc视图解析器bean的注入代码:
<!-- springmvc的配置 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/" /> <property name="suffix" value=".jsp" /> </bean>
