Spring Web Flow和Url重写过滤器-清理URL

如何解决Spring Web Flow和Url重写过滤器-清理URL

|| 我正在研究Spring MVC + Web Flow Web应用程序。我已经将“ 0”映射到MVC Controller，将“ 1”映射到Flow Controller。要从网址中删除“ 2”，我正在尝试使用“ 3”。 MVC控制器（@Controller）中的映射可以很好地实现：

http://localhost:8080/spring/home

->渲染

home

视图。 但是，当请求发送到WebFlow Controller时，出现错误，导致出现“ 6”：

http://localhost:8080/spring/test

->重定向到

http://localhost:8080/spring/app/test?execution=e1s1

->

page not found

。 如何从URL中删除

/app

并使一切正常工作？ urlrewrite.xml：

<?xml version=\"1.0\" encoding=\"utf-8\"?>
<!DOCTYPE urlrewrite PUBLIC \"-//tuckey.org//DTD UrlRewrite 3.0//EN\" \"urlrewrite3.0.dtd\">
<urlrewrite default-match-type=\"wildcard\">
    <!-- to remove /app -->
    <rule>
        <from>/**</from>
        <to>/app/$1</to>
    </rule>
    <outbound-rule>
        <from>/app/**</from>
        <to>/$1</to>
    </outbound-rule>
</urlrewrite>

分派器servlet映射：

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/app/*</url-pattern>
</servlet-mapping>
<filter-mapping>
    <filter-name>UrlRewriteFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

简单控制器：

@Controller
public class MainController {

    @RequestMapping(value={\"/home\",\"/\"})
    public String index(Model model) {
        return \"index\";
    }

}

一些日志：

DEBUG [FlowExecutorImpl:135] : Launching new execution of flow \'test\' with input null

解决方法

我暂时使用定制的FlowHandler做到了。它有效，但是我认为它必须是一个更简单的解决方案...

package utils;
public class PrettyFlowUrlHandler extends DefaultFlowUrlHandler {

    @Override
    public String createFlowDefinitionUrl(String flowId,AttributeMap input,HttpServletRequest request) {
       return cleanUrl(super.createFlowDefinitionUrl(flowId,input,request),request);
    }

    @Override
    public String createFlowExecutionUrl(String flowId,String flowExecutionKey,HttpServletRequest request) {
       return cleanUrl(super.createFlowExecutionUrl(flowId,flowExecutionKey,request);
    }

    protected String cleanUrl(String url,HttpServletRequest request) {
       String pattern = request.getServletPath().substring(1) + \"/\";
       return url.replaceFirst(pattern,\"\");
    }
}

配置：

<bean id=\"flowMappings\" class=\"org.springframework.webflow.mvc.servlet.FlowHandlerMapping\">
    <property name=\"flowRegistry\" ref=\"flowRegistry\"/>
    <property name=\"flowUrlHandler\">
        <bean class=\"utils.PrettyFlowUrlHandler\"/>
    </property>
    <property name=\"order\" value=\"0\" />
</bean>

<bean class=\"org.springframework.webflow.mvc.servlet.FlowHandlerAdapter\">
    <property name=\"flowExecutor\" ref=\"flowExecutor\"/>
    <property name=\"flowUrlHandler\">
        <bean class=\"utils.PrettyFlowUrlHandler\"/>
    </property>
</bean>

编辑 无法使用自定义流处理程序，如下所示：

@Component(\"test\")
public class DataHandler extends AbstractFlowHandler {

    @Override
    public String handleExecutionOutcome(FlowExecutionOutcome outcome,HttpServletRequest request,HttpServletResponse response) {
        // ... checking outcome ...
        return \"/home\"; // redirect to \'404 page not found\',because of rewrite to `/app/app/home`
    }

}

    ,您是否要从网址中删除应用，例如 http://www.mydomain.com/app/home.html并将其更改为 http://www.mydomain.com/home.html 如果是，则应配置server.xml，并且应将应用程序部署为ROOT而不是public_html /或tomcat目录中的app。 这对你有用
