hibernate+spring+springMVC基本配置

web.xml

<!-- Spring配置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:config/springAnnotation-*.xml</param-value> </context-param> <!-- Spring监听 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- SpringMVC配置 --> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <!-- contextConfigLocation是个固定的参数 --> <param-name>contextConfigLocation</param-name> <!-- 加载配置文件 --> <param-value>classpath*:config/springAnnotation-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>

hibernate.cfg.test.xml模板

<hibernate-configuration> <session-factory> <mapping class="com.tgb.web.controller.entity.User"/> </session-factory> </hibernate-configuration>

映射表的类

//实体User映射到表T_USER @Entity @Table(name="T_USER") public class User { @Id //数据库中的主键生成器,值为uuid @GeneratedValue(generator = "system-uuid") @GenericGenerator(name = "system-uuid", strategy = "uuid") private String id; @Column(length=32) private String userName; @Column(length=32) private String age; public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getAge() { return age; } public void setAge(String age) { this.age = age; } public String getId() { return id; } public void setId(String id) { this.id = id; } }

springAnnotation-servlet.xml

<!-- 注解扫描包 --> <context:component-scan base-package="com.tgb.web.controller" /> <!-- 开启注解 --> <mvc:annotation-driven/> <!-- 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>

springAnnotation-core.xml 配置bean

<beans> <bean id="userDao" class="com.tgb.web.controller.dao.UserDAO"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="userManagerBase" class="com.tgb.web.controller.service.UserManager"> <property name="userDao" ref="userDao"></property> </bean> <!--parent="transactionBese" 继承transactionBese（事务管理） --> <!--ref="userManagerBase"" 实现userManagerBase --> <bean id="userManager" parent="transactionBese"> <property name="target" ref="userManagerBase"></property> </bean> </beans>

配置bean的原因：

public class UserDAO implements IUserDAO { //<bean id="userDao" class="com.tgb.web.controller.dao.UserDAO"> // <property name="sessionFactory" ref="sessionFactory"></property> //</bean> private SessionFactory sessionFactory; public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } @Override public void addUser(User user) { sessionFactory.getCurrentSession().save(user); } } public class UserManager implements IUserManager { // <bean id="userManagerBase" class="com.tgb.web.controller.service.UserManager"> //<property name="userDao" ref="userDao"></property> //</bean> private IUserDAO userDao; public void setUserDao(IUserDAO userDao) { this.userDao = userDao; } @Override public void addUser(User user) { userDao.addUser(user); }

controller

@Controller @RequestMapping("/user") public class UserController { @Resource(name="userManager") private IUserManager userManager; @RequestMapping("/toAddUser") public String toAddUser(){ return "/addUser"; }
