springMVC系列之与spring3.2 , hibernate4.1.6整合——08
摘要: 本文主要讲述整合springMVC, spring, hibernate的具体过程, 并连接上oracle进行简单的DUAL.
一: 实现功能
1、springMVC、spring、hibernate整合过程
2、实现简单的DUAL
二：具体步骤
1、springMVC、spring、hibernate整合过程
a) 引入jar包、具体jar包如下图：
b) 使用spring的bean配置关于连接数据库的一些信息、hibernate的常用配置信息、及事务的管理方式springAnnotation-hibernate.xml：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd" [ <!ENTITY contextInclude SYSTEM "org/springframework/web/context/WEB-INF/contextInclude.xml"> ]> <beans> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" /> <property name="url" value="jdbc:oracle:thin:@localhost:1521:chen" /> <property name="username" value="chen" /> <property name="password" value="chen" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <!-- 为sessionFactory注入dataSource --> <property name="dataSource" ref="dataSource" /> <!-- 常用hibernate配置 --> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hiberante.format_sql">true</prop> </props> </property> <!-- 加载用于生成数据库中表的hibernate配置文件。 --> <property name="configLocations"> <list> <value> classpath*:com/chy/ssh/web/annotation/hibernate/hibernate.cfg.test.xml </value> </list> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 事务管理 、当使用spring为每个Controller注入属性时引用此bean、为其添加事务管理 --> <bean id="transactionBese" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" lazy-init="true" abstract="true"> <property name="transactionManager" ref="transactionManager"></property> <!-- 根据不同的操作开启不同的事务管理方式 --> <property name="transactionAttributes"> <props> <prop key="add*">PROPAGATION_REQUIRED,-Exception</prop> <prop key="update*">PROPAGATION_REQUIRED,-Exception</prop> <prop key="insert*">PROPAGATION_REQUIRED,-Exception</prop> <prop key="modify*">PROPAGATION_REQUIRED,-Exception</prop> <prop key="delete*">PROPAGATION_REQUIRED,-Exception</prop> <prop key="get*">PROPAGATION_NEVER</prop> </props> </property> </bean> </beans>
c) 配置hibernate的配置文件、用于生成表。这里不是通过写每一个实体类的hibernate.hbm.xml来对应数据库中的table、而是通过注解的方式来实现的。 hibernate.cfg.test.xml：
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- 用于关联表的实体类 -->
<mapping class="com.chy.ssh.web.annotation.entity.User"/>
</session-factory>
</hibernate-configuration>
具体的entity——User：
package com.chy.ssh.web.annotation.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import org.hibernate.annotations.GenericGenerator;
@Entity
@Table(name="T_USER")
public class User {
@Id
@GeneratedValue(generator="system-uuid")
@GenericGenerator(name="system-uuid", strategy="uuid")
@Column(length=32)
private String id;
@Column(length=32)
private String userName;
@Column(length=32)
private int age;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
d) web.xml加载配置文件：
<?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" id="WebApp_ID" version="2.5"> <!-- 加载配置文件、这里在classpath下写多个不同的文件是为了在团体开发中、不同的小组有不同的配置文件、 这样就不会相互影响、减小冲突、易于管理、最后在主要的配置文件中导入各个模块的配置文件即可！ --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:config/springAnnotation-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <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*:config/springAnnotation-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <!-- encoding filter for jsp page --> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 用于session的管理、解决事务提交后再次操作数据库不能正常打开session的问题 --> <filter> <filter-name>openSession</filter-name> <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class> </filter> <filter-mapping> <filter-name>openSession</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
2、实现简单的DUAL：没有多少要说的地方、主要介绍两个类：UserDAOImpl、UserController、具体的代码中都有说明
a) UserDAOImpl：
package com.chy.ssh.web.annotation.dao;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.SessionFactory;
import com.chy.ssh.web.annotation.entity.User;
public class UserDAOImple implements UserDAO {
private SessionFactory sessionFactory;
public void addUser(User user) {
sessionFactory.getCurrentSession().save(user);
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
@SuppressWarnings("unchecked")
public List<User> getAllUser() {
String hql = "from User";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
return query.list();
}
public boolean delUser(String userId) {
String hql = "delete from User u where u.id=?";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0, userId);
return (query.executeUpdate() > 0);
}
public User getUser(String id) {
String hql = "from User u where u.id=?";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0, id);
return (User) query.uniqueResult();
}
public boolean updateUser(User user) {
String hql = "update User u set u.userName=?,u.age=? where u.id=?";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0, user.getUserName());
query.setInteger(1, user.getAge());
query.setString(2, user.getId());
return (query.executeUpdate() > 0);
}
}
b) UserController：
package com.chy.ssh.web.annotation.controller;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import com.chy.ssh.web.annotation.entity.User;
import com.chy.ssh.web.annotation.service.UserService;
@Controller
@RequestMapping("/user")
public class UserController {
@Resource(name="userManager")
private UserService userManager;
@RequestMapping("/toUser")
public String toUser(){
return "/addUser";
}
@RequestMapping("/addUser")
public String addUser(@ModelAttribute("pojo")User user){
userManager.addUser(user);
return "/success";
}
@RequestMapping("/getAllUser")
public String getAllUser(HttpServletRequest request){
List<User> userList = userManager.getAllUser();
request.setAttribute("userList", userList);
return "/userManager";
}
@RequestMapping("/delUser")
public void delUser(String id,HttpServletResponse response){
String result = "{\"result\":\"error\"}";
if(userManager.delUser(id)){
result = "{\"result\":\"success\"}";
}
PrintWriter out = null;
response.setContentType("application/json");
try {
out = response.getWriter();
out.write(result);
} catch (IOException e) {
e.printStackTrace();
}
}
@RequestMapping("/getUser")
public String getUser(String id,HttpServletRequest request){
User user = userManager.getUser(id);
request.setAttribute("user", user);
return "/editUser";
}
@RequestMapping("/updateUser")
public String updateUser(User user,HttpServletRequest request){
if(userManager.updateUser(user)){
user = userManager.getUser(user.getId());
request.setAttribute("user", user);
return "/editUser";
}else{
return "/error";
}
}
}
补充：
1、整体结构图：
2、第一次访问URL：http://localhost:8080/springMVC_spring_hibernate/user/toUser
3、addUser.jsp：

</html>
4、success.jsp：
<body> springMVC + spring + hibernate 集成成功!!! </body>
5、访问获取所有学生信息URL：http://localhost:8080/springMVC_spring_hibernate/user/getAllUser
6、userManager.jsp：
