我是 Spring 和 Java EE 的新手。有我非常简单的应用程序:

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">

    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

mvc-调度程序-servlet.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

       <context:component-scan base-package="ru.javaheap"/>

       <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
              <property name="prefix" value="/WEB-INF/pages/"/>
              <property name="suffix" value=".jsp"/>
       </bean>

       <mvc:resources mapping="/resources/**" location="/resources/"/>

</beans>

控制器:

@Controller
@RequestMapping("/")
public class HelloController {
    @RequestMapping(method = RequestMethod.GET)
    public String printWelcome(ModelMap model) {
        List<AuthorEntity> authors = HibernateUtil.getSession().createCriteria(AuthorEntity.class).list();
            model.addAttribute("listAuthors", authors);
            return "hello";
    }
}

我使用 glassfish 4.1 和 IDEA。如果没有线

<mvc:resources mapping="/resources/**" location="/resources/"/>

然后它工作正常并打开 hello.jps 页面(没有 css 和 js 资源)。玻璃鱼日志:

当我添加此行以在我的页面中使用资源时,它不会打开页面(错误 404),但我可以打开资源(如http://localhost:8080/untitled_war_exploded/resources/blog.css)。玻璃鱼日志:

以下配置应该适合您,您基本上缺少注释驱动的元素

   <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:context="http://www.springframework.org/schema/context"
           xmlns:mvc="http://www.springframework.org/schema/mvc"
           xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

           <context:component-scan base-package="ru.javaheap"/>

           <mvc:annotation-driven/>

           <mvc:resources mapping="/resources/**" location="/resources/"/>

           <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
                  <property name="prefix" value="/WEB-INF/pages/"/>
                  <property name="suffix" value=".jsp"/>
           </bean>
    </beans>
