德鲁依连接池的数据监控

引入依赖：

 

<dependency>
　　<groupId>com.alibaba</groupId>
　　<artifactId>druid</artifactId>
　　<version>1.1.6</version>
</dependency>

 

编写配置类：DuridConfig

 

package com.frost.config;

import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.boot.context.properties.ConfigurationProperties;
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 javax.sql.DataSource;
import java.util.Arrays;
import java.util.HashMap;

@Configuration
public class DruidConfig {

    //配置德鲁依数据库连接池的信息
    //把yml文件中的属性注入进来
    @ConfigurationProperties(prefix="spring.datasource")
    @Bean
    public DataSource druid(){
        return   new DruidDataSource();
    }
    
    //1.配置servlet
    @Bean
    public ServletRegistrationBean statViewServlet(){
        //进入网战的地址
        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        HashMap<Object, Object> hashMap = new HashMap<>();
        //配置连接的信息
        //用户名
        hashMap.put("loginUsername", "admin");
        //密码
        hashMap.put("loginPassword", "1234");
        //允许访问所有
        hashMap.put("allow","");
        bean.setInitParameters(hashMap);
        return bean;
    }

    //2.配置Filter
    @Bean
    public FilterRegistrationBean webStatFilter() {
        //配置拦截的信息
        FilterRegistrationBean bean = new FilterRegistrationBean(new WebStatFilter());
        HashMap<Object, Object> hashMap = new HashMap<>();
        //不拦截那些信息
        hashMap.put("exclusions", "*.js,*css,/druid/*");
        bean.setInitParameters(hashMap);
        //要过滤那些属性
        bean.setUrlPatterns(Arrays.asList("/*"));
        return bean;
    }
}

 

配置数据库信息：

# 配置数据库连接信息
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/exam?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8
    username: root
    password: root
    type: com.alibaba.druid.pool.DruidDataSource
    initialSize: 5
    minIdle: 5
    maxActive: 20
    maxWait: 60000
    timeBetweenEvictionRunsMillis: 60000
    minEvictableIdleTimeMillis: 300000
    validationQuery: SELECT 1 FROM DUAL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    poolPreparedStatements: true
    #   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
    filters: stat,wall,log4j
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

最后的是时候是在项目的端口号后面加上 durid/login.html 然后账号是：admain 密码是：1234
