java – 如何将Spring MVC控制器映射到带有和不带尾部斜杠的uri？

我有一个 Spring控制器,具有不同URI的几个RequestMappings.我的servlet是“ui”. servlet的基本URI仅适用于尾部斜杠.我希望我的用户不必输入尾部的斜杠.

此URI可用：

http://localhost/myapp/ui/

这不是：

http://localhost/myapp/ui

它给我一个HTTP状态404消息.

我的web.xml中的servlet和映射是：

<servlet>
    <servlet-name>ui</servlet-name>
    <servlet-class>org.springframework.web.servlet.dispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>ui</servlet-name>
    <url-pattern>/ui/*</url-pattern>
</servlet-mapping>

我的控制器

@Controller
public class UiRootController {

    @RequestMapping(value={"","/"})
    public ModelAndView mainPage() { 
        DataModel model = initModel();
        model.setView("intro");     
        return new ModelAndView("main","model",model);
    }

    @RequestMapping(value={"/other"})
    public ModelAndView otherPage() { 
        DataModel model = initModel();
        model.setView("otherPage");     
        return new ModelAndView("other",model);
    }

}

解决方法

如果您的Web应用程序存在于Web服务器的webapps目录中,例如webapps / myapp /,则可以使用http：// localhost：8080 / myapp /来访问此应用程序上下文的根目录,假设默认的Tomcat端口.这应该可以使用或不使用尾部斜线,我认为默认情况下 – 当然是Jetty v8.1.5的情况

一旦你打了/ myapp,Spring DispatcherServlet接管,路由请求到< servlet-name>在您的web.xml中配置,在您的情况下是/ ui / *.

dispatcherServlet然后将所有请求从http：// localhost / myapp / ui /路由到@Controller.

在Controller本身中,您可以使用@RequestMapping(value =“/ *”)作为mainPage()方法,这将导致http：// localhost / myapp / ui /和http：// localhost / myapp / ui路由到mainPage().

注意：由于SPR-7064,您还应该使用Spring> = v3.0.3

为了完整,这里是我测试的文件：

的src /主/爪哇/控制器/ UIRootController.java

package controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class UiRootController {
  @RequestMapping(value = "/*")
  public ModelAndView mainPage() {
    return new ModelAndView("index");
  }

  @RequestMapping(value={"/other"})
  public ModelAndView otherPage() {
    return new ModelAndView("other");
  }
}

WEB-INF / web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
  version="3.0" Metadata-complete="false">
  <servlet>
    <servlet-name>ui</servlet-name>
    <servlet-class>org.springframework.web.servlet.dispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <!-- spring automatically discovers /WEB-INF/<servlet-name>-servlet.xml -->
  </servlet>

  <servlet-mapping>
    <servlet-name>ui</servlet-name>
    <url-pattern>/ui/*</url-pattern>
  </servlet-mapping>
</web-app>

WEB-INF / UI-servlet.xml中

<?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"
  xmlns:context="http://www.springframework.org/schema/context"
  xsi:schemaLocation="http://www.springframework.org/schema/beans
  http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
  http://www.springframework.org/schema/context
  http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<context:component-scan base-package="controllers" />

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
  p:order="2"
  p:viewClass="org.springframework.web.servlet.view.JstlView"
  p:prefix="/WEB-INF/views/"
  p:suffix=".jsp"/>
</beans>

还有2个JSP文件在WEB-INF / views / index.jsp和WEB-INF / views / other.jsp.

结果：

> http：// localhost / myapp / – >目录列表
> http：// localhost / myapp / ui和http：// localhost / myapp / ui / – >的index.jsp
> http：// localhost / myapp / ui / other和http：// localhost / myapp / ui / other / – > other.jsp

希望这可以帮助！
