额外配置

application.yml

    #SpringBoot默认是不注入这些的，需要自己绑定
    #druid数据源专有配置
    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

    #配置监控统计拦截的filters，stat：监控统计、log4j：日志记录、wall：防御sql注入
    #如果允许报错，java.lang.ClassNotFoundException: org.apache.Log4j.Properity
    #则导入log4j 依赖就行
    filters: stat,wall,log4j
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true
    connectionoProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

新建一个config的目录，新建一个类

package com.xuwen.config;

import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import org.springframework.boot.context.properties.ConfigurationProperties;
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.HashMap;

/**

@Configuration
public class DruidConfig {

    //yml和配置文件绑定,1放在bean里面，2ConfigurationProperties绑前缀
    //自定义属性需要绑定
    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druidDataSource(){
        return new DruidDataSource();
    }

    //后台监控-->固定代码,方法,web.xml
    @Bean
    public ServletRegistrationBean StatViewServlet(){
        ServletRegistrationBean<StatViewServlet> bean = new ServletRegistrationBean<>(new StatViewServlet(), "/druid/*");
        //后台需要有人登陆，账号密码设置，固定
        HashMap<String, String> initParameters = new HashMap<>();
        //增加配置,登陆的key，和password写法是固定的，错一个字母，报错
        initParameters.put("loginUsername","admin");
        initParameters.put("loginPassword","123456");

        //允许谁可以访问
        initParameters.put("allow","");

        //禁止谁访问，initParameters.put("xxxx","192.168.0.1");




        bean.setInitParameters(initParameters);//设置初始化参数
        return bean;
    }




}
