org.tukey.web.filters.urlrewrite.UrlRewriteFilter 错误：无法在 urlrewrite.xml 找到 urlrewrite conf 文件答案

【问题标题】：org.tuckey.web.filters.urlrewrite.UrlRewriteFilter ERROR: unable to find urlrewrite conf file at urlrewrite.xmlorg.tukey.web.filters.urlrewrite.UrlRewriteFilter 错误：无法在 urlrewrite.xml 找到 urlrewrite conf 文件

【问题描述】：

我正在尝试在我的 Spring Boot 项目中使用 Tuckey 作为 urlRewrite，但在注册 Tuckey 过滤器时出现错误：

org.tuckey.web.filters.urlrewrite.UrlRewriteFilter ERROR: unable to find urlrewrite conf file at `urlrewrite.xml` even i have `urlrewrite.xml` file under resources.

我在Configuration class 中注册了如下所示的Tucky 过滤器：

@Bean
public FilterRegistrationBean urlRewriteFilterRegistration() throws IOException {
    log.info("UrlRewriteFilter registered!");     
    FilterRegistrationBean registration = new FilterRegistrationBean();
    registration.setFilter(new UrlRewriteFilter());
    registration.setName("UrlRewriteFilter"); 
    List<String> urlPatterns = new ArrayList<>();
    urlPatterns.add("/urlmap");
    registration.setUrlPatterns(urlPatterns); 
    registration.getInitParameters().put("confPath","/urlrewrite.xml");
    return registration;
}

即使我曾经像下面这样注册过滤器：

FilterRegistration.Dynamic urlRewriteFilter = servletContext.addFilter("urlRewriteFilter",  new UrlRewriteFilter());
    urlRewriteFilter.setInitParameter("confPath", "urlrewrite.xml");
    urlRewriteFilter.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST, DispatcherType.FORWARD), false, "/*");

它在无引导版本中工作！我的配置有什么问题。

【解决方案1】：

最近遇到了同样的问题。找到这个帖子有一个答案： Spring boot cannot find urlrewrite.xml inside jar file

TL;DR：创建了一个扩展 UrlRewriteFilter 的类并覆盖了 loadUrlRewriterMethod 以允许将配置加载为 org.springframework.core.io.Resource

请适应您的需求：

public class BootCompliantUrlRewriteFilter extends UrlRewriteFilter {

    private Resource resource;

    public BootCompliantUrlRewriteFilter(Resource config){
        this.resource = config;
    }

    //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 " + this.resource, ex);
        }
    }
}

在应用程序类中：

public static final String REWRITE_FILTER_NAME = "rewriteFilter";
public static final String REWRITE_FILTER_CONF_PATH = "urlrewrite.xml";

@Bean
public FilterRegistrationBean rewriteFilterConfig() {
    FilterRegistrationBean reg = new FilterRegistrationBean();
    reg.setName(REWRITE_FILTER_NAME);
    reg.setFilter(new BootCompliantUrlRewriteFilter(new ClassPathResource(REWRITE_FILTER_CONF_PATH)));

    //reg.addInitParameter("confPath", REWRITE_FILTER_CONF_PATH);
    reg.addInitParameter("confReloadCheckInterval", "-1");
    reg.addInitParameter("statusPath", "/redirect");
    reg.addInitParameter("statusEnabledOnHosts", "*");
    reg.addInitParameter("logLevel", "WARN");
    return reg;
}
