一,Druid是什么?
Druid是Java语言中最好的数据库连接池。Druid能够提供强大的监控和扩展功能。
二, 在哪里下载druid
maven中央仓库: http://central.maven.org/maven2/com/alibaba/druid/
三, 怎么获取Druid的源码
Druid是一个开源项目,源码托管在github上,源代码仓库地址是 https://github.com/alibaba/druid。同时每次Druid发布正式版本和快照的时候,都会把源码打包,你可以从上面的下载地址中找到相关版本的源码

@Bean
public FilterRegistrationBean filterRegistrationBean() {
FilterRegistrationBean bean = new FilterRegistrationBean<>();
bean.setFilter(new WebStatFilter());
Map map = new HashMap<>();
//移除这些监听
map.put(WebStatFilter.PARAM_NAME_EXCLUSIONS, "*.js,*.css,/druid/*,*.gif,*.jpg,*.png");
bean.setInitParameters(map);
//拦截所有请求,全部都要走druid监听
bean.setUrlPatterns(Collections.singletonList("/*"));
return bean;
}
}
测试配置url白名单
如果工程中配置了Apache Shiro,需要在配置类中添加白名单
