Spring Boot找不到URL重写。jar文件中的xml

Question

我正在使用带有嵌入式Tomcat的Spring Boot，而类UrlRewriteFilter找不到配置文件urlrewrite。xml，该类使用servletcontext。getResourceAsStream（this.confPath）和我在另一篇文章中读到，当包是jar时，该方法不起作用。有人有这个问题？

Answer 1

我用的是带Spring靴的Tuckey过滤器。我在这个堆栈溢出问题（不是答案）中遵循了最初的问题实现。我还补充说

registrationBean.addInitParameter("confPath", "urlrewrite.xml");

设置URL重写的特定路径。xml文件。在项目中，我将文件放在src/main/webapp中。

这在使用“mvn spring boot:run”时有效，我认为它满足了在jar中运行的需要。在我的项目中，我构建了一个war文件，这也适用于此。

Answer 2

下面的代码适用于我。

请使用以下依赖项：

         <dependency>
           <groupId>org.tuckey</groupId>
           <artifactId>urlrewritefilter</artifactId>
           <version>4.0.4</version>
         </dependency>

创建URL重写。资源文件夹中的xml：

 <?xml version="1.0" encoding="utf-8"?>
 <!DOCTYPE urlrewrite
    PUBLIC "-//tuckey.org//DTD UrlRewrite 3.0//EN"
    "http://www.tuckey.org/res/dtds/urlrewrite3.0.dtd">

<urlrewrite>
    <rule>
        <name>Domain Name Check</name>
        <condition name="host" operator="notequal">www.userdomain.com</condition>
        <from>^(.*)$</from>
        <to type="redirect">http://www.userdomain.com$1</to>
    </rule>
</urlrewrite>

在主ApplicationRunner中添加以下内容。爪哇：

@Bean
public FilterRegistrationBean tuckeyRegistrationBean() {
    final FilterRegistrationBean registrationBean = new FilterRegistrationBean();
    registrationBean.setFilter(new CustomURLRewriter());
    return registrationBean;
}

并创建CustomURLRewriter：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
import org.springframework.core.io.ClassPathResource;
import org.tuckey.web.filters.urlrewrite.Conf;
import org.tuckey.web.filters.urlrewrite.UrlRewriteFilter;
import org.tuckey.web.filters.urlrewrite.UrlRewriter;
import javax.servlet.*;
import java.io.InputStream;

public class CustomURLRewriter extends UrlRewriteFilter {
private UrlRewriter urlRewriter;

@Autowired
Environment env;

@Override
public void loadUrlRewriter(FilterConfig filterConfig) throws ServletException {
    try {
        ClassPathResource classPathResource = new ClassPathResource("urlrewrite.xml");
        InputStream inputStream = classPathResource.getInputStream();
        Conf conf1 = new Conf(filterConfig.getServletContext(), inputStream, "urlrewrite.xml", "");
        urlRewriter = new UrlRewriter(conf1);
    } catch (Exception e) {
        throw new ServletException(e);
    }
}

@Override
public UrlRewriter getUrlRewriter(ServletRequest request, ServletResponse response, FilterChain chain) {
    return urlRewriter;
}

@Override
public void destroyUrlRewriter() {
    if(urlRewriter != null)
        urlRewriter.destroy();
}
}

在博客文章中找到

import org.springframework.core.io.Resource;
import org.tuckey.web.filters.urlrewrite.Conf;
import org.tuckey.web.filters.urlrewrite.UrlRewriteFilter;

//Adding @Component Annotation to a Filter is enough to register the Filter, when you have no web.xml
@Component
public class MyUrlRewriteFilter extends UrlRewriteFilter {

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

    //Inject the Resource from the given location
    @Value(CONFIG_LOCATION)
    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(), "@@yourOwnSystemId@@");
            checkConf(conf);
        } catch (IOException ex) {
            throw new ServletException("Unable to load URL rewrite configuration file from " + CONFIG_LOCATION, ex);
        }
    }
}
