springboot使用druid连接池,并配置数据源监控
作者:互联网
1.创建一个springboot项目
2.引用依赖,引用log4j是因为需要用到
<!--druid--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.10</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!--druid-->
3.在配置文件application.yml中添加
spring:
datasource:
username: root
password: root
url: jdbc:mysql://localhost:3306/sys?autoReconnect=true&useSSL=false
driver-class-name: com.mysql.jdbc.Driver
type: com.alibaba.druid.pool.DruidDataSource
# 数据源其他配置
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
filters: stat,wall,log4j
maxPoolPreparedStatementPerConnectionSize: 20
useGlobalDataSourceStat: true
connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
4.创建配置文件DruidConfig
package com.fengshun.controller; 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 { // 将所有前缀为spring.datasource下的配置项都加载到DataSource中 @ConfigurationProperties(prefix = "spring.datasource") @Bean public DataSource druidDataSource() { return new DruidDataSource(); } @Bean public ServletRegistrationBean druidStatViewServlet() { ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*"); Map<String, String> initParams = new HashMap<>(); // 可配的属性都在 StatViewServlet 和其父类下 initParams.put("loginUsername", "admin-druid"); initParams.put("loginPassword", "111111"); servletRegistrationBean.setInitParameters(initParams); return servletRegistrationBean; } @Bean public FilterRegistrationBean druidWebStatFilter() { FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter()); Map<String, String> initParams = new HashMap<>(); initParams.put("exclusions", "*.js,*.css,/druid/*"); filterRegistrationBean.setInitParameters(initParams); filterRegistrationBean.setUrlPatterns(Arrays.asList("/*")); return filterRegistrationBean; } }
5.访问druid监控页面,http://localhost:8080/druid/
