Spring MVC3 基本配置

之前用过struts2,学习了spring mvc之后，发现还是比struts2方便一些。

首先，web.xml配置

<filter> <filter-name>springUtf8Encoding</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> </filter> <filter-mapping> <filter-name>springUtf8Encoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param>

也可以配置url-pattern为 / ，这需要在spring配置中添加<mvc:resources mapping="/resources/**" location="/resources/"/>，这个据说只在3.05版本之后支持。

然后是spring mvc配置文件：dispatcher-servlet.xml , 这个名称中的 dispatcher要和web.xml中DispatcherServlet的名称相同

<?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:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/jsp/" p:suffix=".jsp"> </bean> </beans>
然后是spring主配置文件：

启用注解

<context:annotation-config /> <context:component-scan base-package="com.sivalabs"></context:component-scan> <mvc:annotation-driven />

配置place holder，用来读取application configuration

<context:property-placeholder location="/WEB-INF/config.properties"/>

数据源、sessionfactory、事务管理器，其中的

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" p:driverClassName="${jdbc.driverClassName}" p:url="${jdbc.url}" p:username="${jdbc.username}" p:password="${jdbc.password}"> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> </props> </property> <property name="packagesToScan" value="com.sivalabs"></property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" p:sessionFactory-ref="sessionFactory"> </bean> <!-- annotate transactional method --> <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>配置message，默认放置在classpath

<!-- resource message --> <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource" p:basename="Messages"></bean>
Cotroller的写法：

@Controller public class ContactsControllers { private ContactsDAO contactsDAO; @Autowired public void setContactsDAO(ContactsDAO contactsDAO) { this.contactsDAO = contactsDAO; } @Autowired private ContactFormValidator validator; @InitBinder public void initBinder(WebDataBinder binder) { SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy"); dateFormat.setLenient(false); binder.registerCustomEditor(Date.class, new CustomDateEditor( dateFormat, true)); } @RequestMapping("/viewAllContacts") public ModelAndView getAllContacts() { ModelAndView mav = new ModelAndView("showContacts"); List contacts = contactsDAO.getAllContacts(); mav.addObject("SEARCH_CONTACTS_RESULTS_KEY", contacts); return mav; } @RequestMapping(value = "/saveContact", method = RequestMethod.GET) public ModelAndView newuserForm() { ModelAndView mav = new ModelAndView("newContact"); Contact contact = new Contact(); mav.getModelMap().put("newContact", contact); return mav; } @RequestMapping(value = "/saveContact", method = RequestMethod.POST) public String create(@ModelAttribute("newContact") Contact contact, BindingResult result, SessionStatus status) { validator.validate(contact, result); if (result.hasErrors()) { return "newContact"; } contactsDAO.save(contact); status.setComplete(); return "redirect:viewAllContacts.do"; } @RequestMapping(value = "/updateContact", method = RequestMethod.GET) public ModelAndView edit(@RequestParam("id") Integer id) { ModelAndView mav = new ModelAndView("editContact"); Contact contact = contactsDAO.getById(id); mav.addObject("editContact", contact); return mav; } }

<pre></pre>

view中使用spring mvc标签form

<form:form action="saveContact.do" method="post" commandName="newContact"> <!-- form goes here --> </form>
