# springboot集成druid连接池配置 #

在开发项目中如果数据库选型为mysql，很大概率下连接池会使用druid  
这里介绍springboot集成durid

springboot : 2.1.9  
druid : 1.1.10

## springboot集成druid配置 ##

需要引入的pom

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

需要在application.yaml中添加一些配置

spring:
      datasource:
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        platform: mysql
        url: jdbc:mysql://127.0.0.1:3306/xxx?useUnicode=true&characterEncoding=utf8&autoReconnect=true&useSSL=false
        username: root
        password: 123456
        initialSize: 5
        minIdle: 5
        maxActive: 20
        maxWait: 60000
        timeBetweenEvictionRunsMillis: 60000
        minEvictableIdleTimeMillis: 300000
        validationQuery: SELECT1FROMDUAL
        testWhileIdle: true
        testOnBorrow: false
        testOnReturn: false
        filters: stat,wall,log4j
        logSlowSql: true

到此springboot就集成的druid的配置 可以直接使用

## springboot添加druid监控平台配置类 ##

**DruidConfiguration**

    import com.alibaba.druid.support.http.WebStatFilter;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;

    import org.springframework.boot.web.servlet.ServletRegistrationBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    /**
     * 数据库链接池druid监控平台的配置
     * 访问路径 http://localhost:8080/druid/index.html
     *
     */
    @Configuration
    public class DruidConfiguration {
    
        private static final Logger logger = LoggerFactory.getLogger(DruidConfiguration.class);
    
        @Bean
        public ServletRegistrationBean druidServlet() {
            logger.info("init Druid Servlet Configuration ");
            ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
            // IP白名单
    //        servletRegistrationBean.addInitParameter("allow", "*");
            // IP黑名单(共同存在时，deny优先于allow)
    //        servletRegistrationBean.addInitParameter("deny", "192.168.1.100");
            //控制台管理用户
            servletRegistrationBean.addInitParameter("loginUsername", "admin");
            servletRegistrationBean.addInitParameter("loginPassword", "admin");
            //是否能够重置数据 禁用HTML页面上的“Reset All”功能
            servletRegistrationBean.addInitParameter("resetEnable", "false");
            return servletRegistrationBean;
        }
        @Bean
        public FilterRegistrationBean filterRegistrationBean() {
            FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
            filterRegistrationBean.addUrlPatterns("/*");
            filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
            return filterRegistrationBean;
        }
    }
