由于没有使用maven所以直接看包结构吧!后续可能会带有maven的!
</pre><p></p><p>包有点多,但是不要在乎这些细节,多总比少好。</p><p>下面看配置文件</p><p>spring-common.xml(相当于applicationContext.xml)</p><p></p><pre name="code" class="html"><?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:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!--配置数据源 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> <property name="url" value="jdbc:mysql://localhost:3306/test"></property> <property name="username" value="root"></property> <property name="password" value="root"></property> </bean> <!--配置SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <!--配置数据库方言 --> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> </props> </property> <property name="packagesToScan"> <list> <value>com.iss.model</value> </list> </property> </bean> <!-- 配置一个事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- 配置事务,使用代理的方式 --> <bean id="transactionProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" abstract="true"> <property name="transactionManager" ref="transactionManager"></property> <property name="transactionAttributes"> <props> <prop key="add*">PROPAGATION_REQUIRED,-Exception</prop> <prop key="modify*">PROPAGATION_REQUIRED,-myException</prop> <prop key="del*">PROPAGATION_REQUIRED</prop> <prop key="*">PROPAGATION_REQUIRED</prop> </props> </property> </bean> </beans>
还有一个就是SpringMVC的配置文件
spring-mvc.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" xmlns:mvc="http://www.springframework.org/schema/mvc" 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-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <!-- 注解扫描包 --> <context:component-scan base-package="com.iss" /> <!-- 开启注解 --> <mvc:annotation-driven /> <!-- 静态资源(js/image)的访问 --> <mvc:resources location="/js/" mapping="/js/**" /> <!-- 定义视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/"></property> <property name="suffix" value=".jsp"></property> </bean> </beans>
最后是web.xml
<?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"> <display-name>json_test</display-name> <welcome-file-list> <welcome-file>login.jsp</welcome-file> </welcome-file-list> <!-- 加载所有的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:spring-*.xml</param-value> </context-param> <!-- 配置Spring监听 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置SpringMVC --> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>WEB-INF/classes/spring-mvc.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> <!-- 配置字符集 --> <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> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置Session --> <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>
好了所有的配置文件能完成了下面看逻辑代码。
com.iss.model.User.class
package com.iss.model; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table; /** * @author dell * */ @Entity @Table(name = "user") public class User { private int id; private String name; @Id @GeneratedValue(strategy = GenerationType.AUTO) 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; } }
com.iss.dao.UserDao.class
package com.iss.dao; import java.util.List; import com.iss.model.User; public interface UserDao { public User addUser(User user); public List<User> getAllUsers(); public User getUser(int userId); public void deleteUser(User user); }
com.iss.dao.impl.UserDaoImpl.class
package com.iss.dao.impl; import java.util.List; import org.hibernate.Query; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Repository; import com.iss.dao.UserDao; import com.iss.model.User; @Repository public class UserDaoImpl implements UserDao { private SessionFactory sessionFactory; @Autowired public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } public User addUser(User user) { Session session = sessionFactory.getCurrentSession(); session.saveOrUpdate(user); session.flush(); return user; } public List<User> getAllUsers() { Session session = sessionFactory.getCurrentSession(); Query query = session.createQuery("from User"); List<User> users = query.list(); session.flush(); return users; } public User getUser(int userId) { Session session = sessionFactory.getCurrentSession(); User user = (User) session.get(User.class, userId); return user; } public void deleteUser(User user) { Session session = sessionFactory.getCurrentSession(); session.delete(user); session.flush(); } }
com.iss.service.UserService.class
package com.iss.service; import java.util.List; import com.iss.model.User; public interface UserService { public User addUser(User user); public List<User> getAllUsers(); public User getUser(int userId); public void deleteUser(User user); }
com.iss.service.UserServiceImpl.class
package com.iss.service.impl; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.iss.dao.UserDao; import com.iss.model.User; import com.iss.service.UserService; @Service("UserService") public class UserServiceImpl implements UserService { private UserDao userDao; @Autowired public void setUserDao(UserDao userDao) { this.userDao = userDao; } public User addUser(User user) { // TODO Auto-generated method stub return userDao.addUser(user); } public List<User> getAllUsers() { // TODO Auto-generated method stub return userDao.getAllUsers(); } public User getUser(int userId) { // TODO Auto-generated method stub return userDao.getUser(userId); } public void deleteUser(User user) { userDao.deleteUser(user); } }
com.iss.controller.UserController
package com.iss.controller; import java.io.IOException; import java.util.List; import javax.servlet.http.HttpServletResponse; 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 com.iss.model.User; import com.iss.service.UserService; @Controller @RequestMapping("/user") public class UserController { private UserService userService; @Autowired public void setUserService(UserService userService) { this.userService = userService; } @RequestMapping("/toAddUser") public String toAddUser() { return "addUser"; } @RequestMapping("/toUpdateUser") public String toUpdateUser(int id, ModelMap modelMap) { User user = userService.getUser(id); modelMap.addAttribute("user", user); return "editUser"; } @RequestMapping("/addUser") public String addUser(User user) { userService.addUser(user); return "redirect:/user/getAllUser"; } @RequestMapping("/getAllUser") public String getAllUsers(ModelMap modelMap) { List<User> userList = userService.getAllUsers(); modelMap.addAttribute("userList", userList); return "index"; } @RequestMapping("/delUser") public String delUser(int id, HttpServletResponse response) throws IOException { User user = userService.getUser(id); System.err.println(user.getName()); userService.deleteUser(user); response.getWriter().print("success"); return null; } }
下面是几个jsp页面的代码
login.jsp
<body> <h5> <a href="user/getAllUser">进入用户管理页</a> </h5> </body>
index.jsp
<body> <h6> <a href="toAddUser">添加用户</a> </h6> <table border="1"> <tbody> <tr> <th>姓名</th> <th>年龄</th> <th>操作</th> </tr> <c:if test="${!empty userList }"> <c:forEach items="${userList }" var="user"> <tr id="tr${user.id }"> <td>${user.id }</td> <td>${user.name}</td> <td><a href="toUpdateUser?id=${user.id }">编辑</a> <a href="javascript:del(${user.id })">删除</a> </td> </tr> </c:forEach> </c:if> </tbody> </table> </body>
其中删除用了Jquery需引用?Jquery包
<script type="text/javascript" src="../js/jQuery.js"></script> <script type="text/javascript"> function del(id) { /* $.get("delUser?id=" + id, function(data) { alert(data); if ("success" == data) { alert("删除成功"); $("#tr" + id).remove(); } else { alert("删除失败"); } }); */ var url = "delUser?id=" + id; $.ajax({ type : "post", url : url, dataType : "text", success : function(data) { if ("success" == data) { alert("删除成功"); $("#tr" + id).remove(); } else { alert("删除失败"); } } }); } </script>
editUser.jsp
<h1>编辑用户</h1> <form action="addUser" name="userForm" method="post"> <input type="hidden" name="id" value="${user.id }"> 姓名:<input type="text" name="name" value="${user.name }"> <input type="submit" value="编辑"> </form>
addUser.jsp
<body> <h1>添加用户</h1> <form action="" name="userForm"> 姓名:<input type="text" name="name"> <input type="button" value="添加" onclick="addUser()"> </form> </body>
其中js代码
<script type="text/javascript"> function addUser() { var form = document.forms[0]; form.action = "addUser"; form.method = "post"; form.submit(); } </script>
以上基本完成了Spring-SpringMVC-Hibernate之间的整合并进行了基本的crud操作。当然还有许多不足之处还望轻喷!
