druid监控配置

大家好，又见面了，我是你们的朋友全栈君。

maven依赖:

    <dependency>
      <groupId>com.alibaba</groupId>
      <artifactId>druid-spring-boot-starter</artifactId>
      <version>1.1.10</version>

spring.datasource.password = root
spring.datasource.driver-class-name = com.mysql.jdbc.Driver
#连接池的配置信息
#初始化大小，最小，最大
spring.datasource.druid.initialSize=2
spring.datasource.druid.minIdle=2
spring.datasource.druid.maxActive=3
#配置获取连接等待超时的时间
spring.datasource.druid.maxWait=6000
#配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
spring.datasource.druid.timeBetweenEvictionRunsMillis=60000
#超过时间限制是否回收
spring.datasource.druid.removeAbandoned=true
#超过时间限制多长
spring.datasource.druid.removeAbandonedTimeout=1800
#指定发生removeabandoned的时候，是否记录当前线程的堆栈信息到日志中
spring.datasource.druid.logAbandoned=true
#配置一个连接在池中最小生存的时间，单位是毫秒
spring.datasource.druid.minEvictableIdleTimeMillis=300000
#用来检测连接是否有效的sql，要求是一个查询语句
spring.datasource.druid.validationQuery=SELECT 1 FROM DUAL
#申请连接的时候检测
spring.datasource.druid.testWhileIdle=true
# 申请连接时执行validationQuery检测连接是否有效，配置为true会降低性能
spring.datasource.druid.testOnBorrow=false
#归还连接时执行validationQuery检测连接是否有效，配置为true会降低性能
spring.datasource.druid.testOnReturn=false
#打开PSCache，并且指定每个连接上PSCache的大小
spring.datasource.druid.poolPreparedStatements=true
spring.datasource.druid.maxPoolPreparedStatementPerConnectionSize=20
#配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙
spring.datasource.druid.filters=stat,wall
#通过connectProperties属性来打开mergeSql功能；慢SQL记录
spring.datasource.druid.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

            LOGGER.error("druid configuration initialization filter", e);
        }
        return datasource;

}

DruidStatFilter:

package com.xinjianqiao.mian.druid;

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

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

@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 {
}

DruidStatViewServlet:

package com.xinjianqiao.mian.druid;

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

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

@WebServlet(urlPatterns="/druid/*",
        initParams={
                @WebInitParam(name="allow",value=""),// IP白名单(没有配置或者为空，则允许所有访问)
                /* @WebInitParam(name="deny",value="192.168.188.130"),*/// IP黑名单 (存在共同时，deny优先于allow)

                @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 = -2688872071445249539L;
}

启动类添加扫描注解:

package com.xinjianqiao.mian;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.boot.web.support.SpringBootServletInitializer;

/**
 *
 * @author Administrator
 * @date 2018/12/6
 */
@ServletComponentScan
@SpringBootApplication
@MapperScan(value = "com.xinjianqiao.mian.dao")
public class SpringbootStart extends SpringBootServletInitializer {
    public static void main(String[] args){
        SpringApplication.run(SpringbootStart.class,args);
    }
}
