Spring Boot 中 Druid 的監控頁面配置

Druid的性能相比HikariCp等其他數據庫連接池有一定的差距，但是數據庫的相關屬性的監控，別的連接池可能還追不上，如圖：

今天寫一下 Spring Boot 中監控頁面的配置，我是直接將seata中的相關Druid的Servlet 和 Filter的配置粘貼出來。

import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;

@Configuration
public class DruidConfig {

    /**
     * 注冊一個StatViewServlet
     *
     * @return servlet registration bean
     */
    @Bean
    public ServletRegistrationBean druidStatViewServlet() {
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(
            new StatViewServlet(), "/druid/*");

        servletRegistrationBean.addInitParameter("loginUsername", "admin");
        servletRegistrationBean.addInitParameter("loginPassword", "123456");
        servletRegistrationBean.addInitParameter("resetEnable", "false");
        return servletRegistrationBean;
    }

    /**
     * 注冊一個：filterRegistrationBean
     *
     * @return filter registration bean
     */
    @Bean
    public FilterRegistrationBean druidStatFilter() {

        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(
            new WebStatFilter());

        // 添加過濾規則.
        filterRegistrationBean.addUrlPatterns("/*");

        // 添加不需要忽略的格式信息.
        filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
        return filterRegistrationBean;
    }
}

以供參考
