Spring MVC 放行靜態資源

使用Spring MVC 放行靜態資源有三種方法：

1.使用<mvc:resource mapping ="/staticDir/**"  location = "/src/" />

2.使用<mvc:default-servlet-handler />

3.在web.xml中配置

    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>*.jpg</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>*.js</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>*.css</url-pattern>
    </servlet-mapping>

"default" 是Tomcat的默認servlet的名稱

4.配置DispatchServle的URL匹配規則

<servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

如果使用前面倆種方法，必須配置<mvc:annotation-driven>,否則會對使用註解的@Controller產生影響，報404錯誤
