以下是我的项目结构: enter image description here
我有这些文件:
Web.xml的内容如下:
<display-name>Java EE Starter Application</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring-mvc-context.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>springHibernateDemo2</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springHibernateDemo2</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
spring-mvc-context.xml的内容如下:
<context:component-scan base-package="com.abhinav" />
<mvc:annotation-driven/>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>
<mvc:resources mapping="/static/**" location="/" />
<mvc:default-servlet-handler />
db-config.xml具有以下内容:
<context:property-placeholder location="classpath:database.properties"/>
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" destroy-method="close">
<property name="driverClassName" value="${database.driverClassName}" />
<property name="url" value="${database.url}" />
<property name="username" value="${database.username}" />
<property name="password" value="${database.password}" />
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<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>
</props>
</property>
<property name="packagesToScan" value="com.abhinav.data"></property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate5.HibernateTemplate">
<constructor-arg name="sessionFactory" ref="sessionFactory"/>
</bean>
<bean class="com.abhinav.data.UserDao2" />
<tx:annotation-driven transaction-manager="transactionManager" />
BaseDao.java
public class BaseDao extends HibernateDaoSupport {
@Autowired
SessionFactory sessionFactory;
@SuppressWarnings("unchecked")
public List getAll(Class clazz) {
return getHibernateTemplate().findByCriteria(DetachedCriteria.forClass(clazz));
}
}
@Repository("userDao2")
public class UserDao2 extends BaseDao {
@SuppressWarnings("unchecked")
public List<User> getAllUsers() {
String sqlQuery = "select id, first_name, email from users";
SQLQuery query = currentSession().createSQLQuery(sqlQuery);
query.addEntity(User.class);
return (List<User>)query.list();
}
}
UserController.java
@Controller
public class UserController {
@Autowired
private UserDao2 userDao2 = new UserDao2();
@RequestMapping(value="/users", method = RequestMethod.GET)
public String displayUsers (Model model) {
model.addAttribute("users",userDao2.getAllUsers());
return "users";
}
}
我收到“sessionFactory”所需的错误。无法弄清楚我哪里出错了。几天来我一直坚持不懈。
