背景

后台接收的请求，希望把请求URL做重定向，改变原有的请求，此篇可以帮助你解决这个问题,可以用来改变常规URL重定向，也可以隐藏所访问的静态资源

代码实现部分

实现这个功能需要以下几个步骤

pom中引用jar
增加一个配制类
resource文件夹下增加一个配置文件

以下对上述步骤展开具体说明

pom中引用jar

  <!--地址重定向用-->
        <dependency>
            <groupId>org.tuckey</groupId>
            <artifactId>urlrewritefilter</artifactId>
            <version>4.0.4</version>
        </dependency>

增加一个配制类

import java.io.IOException;

import javax.servlet.FilterConfig;
import javax.servlet.ServletException;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.Resource;
import org.tuckey.web.filters.urlrewrite.Conf;
import org.tuckey.web.filters.urlrewrite.UrlRewriteFilter;

@Configuration
public class UrlRewriteFilterConfig extends UrlRewriteFilter {

    private static final String URL_REWRITE = "classpath:/urlrewrite.xml";

    // Inject the Resource from the given location
    @Value(URL_REWRITE)
    private Resource resource;

    // Override the loadUrlRewriter method, and write your own implementation
    @Override
    protected void loadUrlRewriter(FilterConfig filterConfig) throws ServletException {
        try {
            // Create a UrlRewrite Conf object with the injected resource
            Conf conf = new Conf(filterConfig.getServletContext(), resource.getInputStream(), resource.getFilename(),
                    "@@systemID@@"); //最后的参数是自己系统的标识ID即可
            checkConf(conf);
        } catch (IOException ex) {
            throw new ServletException("Unable to load URL rewrite configuration file from " + URL_REWRITE, ex);
        }
    }
}

增加需要重定向的配置文件

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 4.0//EN"
        "http://www.tuckey.org/res/dtds/urlrewrite4.0.dtd">

<urlrewrite>

    <!-- 栏目首页 -->
    <rule>
        <from>/test/</from>
        <to>/</to>
    </rule>

    <!-- 栏目列表页，注意html后面没有加$，因为后面还有若干参数 -->
    <rule>
        <from>^/test/list/(\w+)/(\w+)\.html</from>
        <to>/test/list/$1/$2/</to>
    </rule>

    <!-- 文章详情页 -->
    <rule>
        <from>^/test11/(\w+)\.html$</from>
        <to>/realTime/$1/</to>
    </rule>

    <!-- 静态网页 -->
    <rule>
        <from>^/static/(\w+)\.html$</from>
        <to>/static/$1/</to>
    </rule>

</urlrewrite>
