先看一下xml配置的,很多博客写出来都差不多,但是又不详细。
直接看一下老外的回答,How to handle static content in Spring MVC?
国内的博客里面一般就这样写。
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
就写出一块,其实我们可以写的再详细点,贴个完整的路径和配置出来。
WebContent/WEB-INF/web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun/xml/ns/j2ee"
xmlns:xsi="http://www.w3/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun/xml/ns/j2ee

<servlet>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
WebContent/WEB-INF/springmvc-servlet.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework/schema/beans"
xmlns:xsi="http://www.w3/2001/XMLSchema-instance" xmlns:context="http://www.springframework/schema/context"

<!-- not strictly necessary for this example, but still useful, see http://static.springsource/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-ann-controller for more information -->
<context:component-scan base-package="springmvc.web" />
<!-- the mvc resources tag does the magic -->
<mvc:resources mapping="/resources/**" location="/resources/" />
<!-- also add the following beans to get rid of some exceptions -->
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<bean
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
</bean>
<!-- JSTL resolver -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
在Spring MVC实战(一)——读《Spring in action》搭建最简单的MVC中继承AbstractAnnotationConfigDispatcherServletInitializer的类自动的配置了DispatcherServlet和
spring的应用上下文。所以我是没在web.xml中配置任何东西的。
但是我又不想在xml配置之后才能访问到静态资源和HTML,找来找去没有我想要的,那怎么办,还是看文档。http://docs.spring.io/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-config-enable
思路就是找到要搜索的关键词,static resource。
看到了文档中的HTTP caching support for static resources
@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**")
.addResourceLocations("/public-resources/")
.setCacheControl(CacheControl.maxAge(1, TimeUnit.HOURS).cachePublic());
}
}
And in XML:
<mvc:resources mapping="/resources/**" location="/public-resources/">
<mvc:cache-control max-age="3600" cache-public="true"/>
</mvc:resources>
由于CacheControl是4.2版本之后才有的,我当前是4.1版本,所以去除setCacheControl方法。
现在的整个WebConfig.java
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
@Configuration
@EnableWebMvc
@ComponentScan("spittr.web")
public class WebConfig extends WebMvcConfigurerAdapter {
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
return resolver;
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**")
.addResourceLocations("/static/");
}
}
将test.html 置于WebContent/WEB-INF/static目录
此后再访问http://localhost:8080/projectname/static/test.html即可访问,而无需在web.xml配置任何的东西。
