删除Druid下方的阿里云广告

目前druid-1.1.14的web控制台依然存在阿里云的广告，本文通过过滤器将广告文本拦截。定位问题产生广告的JS文件在 druid-1.1.14.jar/support/http/resources/js/common.js。查看源码可知是buildFooter方法进行植入，由init方法调用。解决问题/** * Druid的配置类 * * @author BBF /@Configuration@AutoConfigureAfter(DruidDataSourceAutoConfigure.class)public class DruidConfig { /* * 带有广告的common.js全路径，druid-1.1.14 / private static final String FILE_PATH = “support/http/resources/js/common.js”; /* * 原始脚本，触发构建广告的语句 / private static final String ORIGIN_JS = “this.buildFooter();”; /* * 替换后的脚本 / private static final String NEW_JS = “//this.buildFooter();”; /* * 去除Druid监控页面的广告 * * @param properties DruidStatProperties属性集合 * @return {@link org.springframework.boot.web.servlet.FilterRegistrationBean} / @Bean @ConditionalOnWebApplication @ConditionalOnProperty(name = “spring.datasource.druid.stat-view-servlet.enabled”, havingValue = “true”) public FilterRegistrationBean<RemoveAdFilter> removeDruidAdFilter( DruidStatProperties properties) throws IOException { // 获取web监控页面的参数 DruidStatProperties.StatViewServlet config = properties.getStatViewServlet(); // 提取common.js的配置路径 String pattern = config.getUrlPattern() != null ? config.getUrlPattern() : “/druid/”; String commonJsPattern = pattern.replaceAll("\*", “js/common.js”); // 获取common.js String text = Utils.readFromResource(FILE_PATH); // 屏蔽 this.buildFooter(); 不构建广告 final String newJs = text.replace(ORIGIN_JS, NEW_JS); FilterRegistrationBean<RemoveAdFilter> registration = new FilterRegistrationBean<>(); registration.setFilter(new RemoveAdFilter(newJs)); registration.addUrlPatterns(commonJsPattern); return registration; } /** * 删除druid的广告过滤器 * * @author BBF */ private class RemoveAdFilter implements Filter { private final String newJs; public RemoveAdFilter(String newJS) { this.newJs = newJS; } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { chain.doFilter(request, response); // 重置缓冲区，响应头不会被重置 response.resetBuffer(); response.getWriter().write(newJs); } }}
