Spring Boot使用Druid和监控配置

修改pom

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.0</version>
        </dependency>

修改配置文件

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=123456

方式一

新建filter

package com.example.demo.servlet;

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

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

/**
 * druid过滤器.
 *
 * @author :小虎
 * @date :2017/12/26
 */

@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 {

}

新建servlet

package com.example.demo.servlet;

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

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

/**
 * druid数据源状态监控.
 *
 * @author :小虎
 * @date :2017/12/26
 */


@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 = "admin"),// 用户名
                @WebInitParam(name = "loginPassword", value = "123456"),// 密码
                @WebInitParam(name = "resetEnable", value = "false")// 禁用HTML页面上的“Reset All”功能
        }
)
public class DruidStatViewServlet extends StatViewServlet {
    private static final long serialVersionUID = 1L;

}

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。

方式二

新建config

package com.example.demo.config;

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

/**
 * druid 配置.
 * 这样的方式不需要添加注解：@ServletComponentScan
 * @author :小虎
 * @date :2017/12/26
 */


@Configuration
public class DruidConfiguration {

    /**
     * 注册一个StatViewServlet
     * @return
     */
    @Bean
    public ServletRegistrationBean DruidStatViewServle2(){
        //org.springframework.boot.context.embedded.ServletRegistrationBean提供类的进行注册.
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid2/*");

        //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","admin2");
        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 druidStatFilter2(){

        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;
    }

}
