2.DruidConfig配置

package com.cloudtech.web.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;
import java.util.Map;

@Configuration
public class DruidConfig {

    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druid(){
        return  new DruidDataSource();
    }

    //配置Druid的監控
    //1、配置一個管理後臺的Servlet
    @Bean
    public ServletRegistrationBean<StatViewServlet> statViewServlet(){
        ServletRegistrationBean<StatViewServlet> bean = new ServletRegistrationBean<StatViewServlet>(new StatViewServlet(), "/druid/*");
        Map<String,String> initParams = new HashMap<>();

        initParams.put("loginUsername","admin");
        initParams.put("loginPassword","123456");
        initParams.put("allow","");//預設就是允許所有訪問
        initParams.put("deny","192.168.15.21");

        bean.setInitParameters(initParams);
        return bean;
    }


    //2、配置一個web監控的filter
    @Bean
    public FilterRegistrationBean<WebStatFilter> webStatFilter(){
        FilterRegistrationBean<WebStatFilter> bean = new FilterRegistrationBean<WebStatFilter>();
        bean.setFilter(new WebStatFilter());

        Map<String,String> initParams = new HashMap<>();
        initParams.put("exclusions","*.js,*.css,/druid/*");

        bean.setInitParameters(initParams);

        bean.setUrlPatterns(Arrays.asList("/*"));

        return  bean;
    }
}
 

3.application.yml配置

spring:
    datasource:
    #   資料來源基本配置
        url: jdbc:mysql://192.168.1.139:3306/sclimate?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
        username: root
        password: root
        driver-class-name: com.mysql.jdbc.Driver
        type: com.alibaba.druid.pool.DruidDataSource
    #   資料來源其他配置
        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
    #   配置監控統計攔截的filters，去掉後監控介面sql無法統計，'wall'用於防火牆
        filters: stat,wall,log4j
        maxPoolPreparedStatementPerConnectionSize: 20
        useGlobalDataSourceStat: true
        connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
 

啟動後的地址為http://localhost:8080/climate/druid/

climate為專案名，如果spring boot對應的配置沒有增加專案對映，地址中無需增加專案名
