使用druid的来监控SQL

配置Servlet

如下是在SpringBoot项目中基于注解的配置，如果是web.xml配置，按规则配置即可。

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

import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;

/**
 * Created by p.ww on 2017-12-27.
 * druid监控页面
 */
@SuppressWarnings("serial")
@WebServlet(urlPatterns = "/druid/*",
        initParams={
                @WebInitParam(name="allow",value="192.168.1.72,127.0.0.1"),// IP白名单(没有配置或者为空，则允许所有访问)
                @WebInitParam(name="deny",value="192.168.1.73"),// IP黑名单 (存在共同时，deny优先于allow)
                @WebInitParam(name="loginUsername",value="ruoshan"),// 用户名
                @WebInitParam(name="loginPassword",value="mynameisruoshan"),// 密码
                @WebInitParam(name="resetEnable",value="false")// 禁用HTML页面上的“Reset All”功能
        })
public class DruidStatViewServlet extends StatViewServlet {

}

 

配置Filter

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

import javax.servlet.annotation.WebFilter;
import javax.servlet.annotation.WebInitParam;

/**
 * Created by p.ww on 2017-12-27.
 *
 */
@WebFilter(filterName="druidWebStatFilter",urlPatterns="/*",
        initParams={
                @WebInitParam(name="exclusions",value="*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*")// 忽略资源
        })
public class DruidStatFilter extends WebStatFilter {

}

最后在App.java类上加上注解：@ServletComponentScan是的spring能够扫描到我们自己编写的servlet和filter。

然后启动项目后访问 http://127.0.0.1:8080/druid/index.html 即可查看数据源及SQL统计等。 

 

第二种:

import org.springframework.boot.context.embedded.FilterRegistrationBean;
import org.springframework.boot.context.embedded.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;

/**
 * druid 配置.
 * @author  p.ww 2017-12-27
 */
@Configuration
public class DruidConfiguration {

    /**
     * 注册一个StatViewServlet
     * @return
     */
    @Bean
    public ServletRegistrationBean DruidStatViewServle(){
        //org.springframework.boot.context.embedded.ServletRegistrationBean提供类的进行注册.

        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");

        //添加初始化参数：initParams
        //白名单：
//        servletRegistrationBean.addInitParameter("allow","127.0.0.1");
        //IP黑名单 (存在共同时，deny优先于allow) : 如果满足deny的话提示:Sorry, you are not permitted to view this page.
//        servletRegistrationBean.addInitParameter("deny","192.168.1.73");
        //登录查看信息的账号密码.
        servletRegistrationBean.addInitParameter("loginUsername","admin");
        servletRegistrationBean.addInitParameter("loginPassword","123456");
        //是否能够重置数据.
        servletRegistrationBean.addInitParameter("resetEnable","false");
        return servletRegistrationBean;
    }


    /**
     * 注册一个：filterRegistrationBean
     * @return
     */
    @Bean
    public FilterRegistrationBean druidStatFilter(){
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
        //添加过滤规则.
        filterRegistrationBean.addUrlPatterns("/*");
        //添加不需要忽略的格式信息.
        filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid2/*");
        return filterRegistrationBean;
    }
}

根据相应的数据能够访问
