spring Boot 集成阿里数据连接池 druid

1.pom.xml 添加坐标

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.10</version>
        </dependency>

        <!--自启动Druid管理后台-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.10</version>
        </dependency>

2. 在yml配置文件添加配置

       datasource:
		  url: jdbc:mysql://47.110.250.68:3306/nslyd?serverTimezone=Asia/Shanghai
		  username: root
		  password: 123456
		  driver-class-name: com.mysql.cj.jdbc.Driver
		  type: com.alibaba.druid.pool.DruidDataSource
		  # 下面为连接池的补充设置，应用到上面所有数据源中
		  # 初始化大小，最小，最大
		  initial-size: 5
		  min-idle: 5
		  max-active: 20
		# 配置获取连接等待超时的时间
		  max-wait: 60000
		# 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
		  time-between-eviction-runs-millis: 60000
		# 配置一个连接在池中最小生存的时间，单位是毫秒
		  min-evictable-idle-time-millis: 300000
		  validation-query: SELECT 1 FROM DUAL
		  test-while-idle: true
		  test-on-borrow: false
		  test-on-return: false
		# 打开PSCache，并且指定每个连接上PSCache的大小
		  pool-prepared-statements: 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
		  max-pool-prepared-statement-per-connection-size: 20
		  filters: stat,wall
		  use-global-data-source-stat: true
		# 通过connectProperties属性来打开mergeSql功能；慢SQL记录
		  connect-properties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

3. 编写config配置类

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


@Configuration
public class DruidConfiguration {

    private final Logger logger = LoggerFactory.getLogger(DruidConfiguration.class);

    @Bean
    public ServletRegistrationBean druidServlet() {
        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", "123456");
        //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;
    }

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