关于druid的一些设置（idea版本）

关于druid的一些设置（idea版本）

1、首先是加入依赖

		<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.2.4</version>
        </dependency>
        

2、applocation.properties

spring.datasource.username=root//账号密码根据自己需求来
spring.datasource.password=z1314520
spring.datasource.url=jdbc:mysql://localhost:3306/mybatis?useSSL=true&serverTimezone=GMT%2B8
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
#Spring Boot默认是不注入这些属性值的，需要自己绑定
#druid数据源专有配固
spring.datasource.initialsize=5
spring.datasource.minIdle=5
spring.datasource.maxActive= 20
spring.datasource.maxwait= 60000
spring.datasource.timeBetweenEvictionRunsMillis= 60000
spring.datasource.minEvictableIdleTimeMillis= 300000
spring.datasource.validationQuery= SELECT 1 FROM DUAL
spring.datasource.testWhileIdle= true
spring.datasource.testOnBorrow= false
spring.datasource.testOnReturn= false
spring.datasource.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
#如果允许时报错java. lang. ClassNotFoundException: org. apache. log4j. Priority
#则导入Log4j 依赖即可，Maven 地址: https://mvnrepository. com/artifact/log4j/log4j
spring.datasource.filters= stat, wall, log4j
spring.datasource.maxPoolPreparedStatementPerConnectionSize= 20
spring.datasource.useGlobalDataSourceStat= true
spring.datasource.connectionProperties= druid.stat.mergeSql=true; druid.stat.slowSqlMillis=500

3、MyDuridConfig.java

package com.biubiu.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;

/**
 * @author z2424
 */
@Configuration
public class MyDruidConfig {

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource druiddatasource(){
        return  new DruidDataSource();
    }
    //后台监控
    @Bean
    public ServletRegistrationBean statViewServletServletRegistrationBean (){
         ServletRegistrationBean<StatViewServlet> Bean = new ServletRegistrationBean<>(new StatViewServlet(), "/druid/*");
         //配置后台账号密码
         HashMap<String, String> Map = new HashMap<>();
        //loginUsername是固定的
         Map.put("loginUsername","admin");
        //loginPassword是固定的
        Map.put("loginPassword","admin");
        // 访问权限
        // map.put("allow","localhost");
        // 只允许本机访问
        Map.put("allow", "");
        // 所有人都可以访问
        // deny拒绝访问
        // map.put("deny","192.168.1.1"); // ip会被拒绝访问
        //设置servlet的初始化参数
       Bean.setInitParameters(Map);
        return Bean;
    }
}

学的不精，
