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;
    }
}

view中使用spring mvc标签form

<p></p>
<pre name="code" class="html"><form:form action="saveContact.do" method="post" commandName="newContact">
