SpringBoot|SpringBoot 整合 druid数据源数据源|druid

1.引入maven 依赖

com.alibaba druid 1.1.10

2.在application.properties 中配置

spring.datasource.url=jdbc:mysql://127.0.0.1/spring_jpa?useSSL=false&serverTimezone=Hongkong spring.datasource.username: root spring.datasource.password: 123456 spring.datasource.driver-class-name: com.mysql.cj.jdbc.Driver#druid连接池 spring.datasource.type: com.alibaba.druid.pool.DruidDataSource #最大活跃数 spring.datasource.maxActive: 20 #初始化数量 spring.datasource.initialSize: 1 #最大连接等待超时时间 spring.datasource.maxWait: 60000 #打开PSCache，并且指定每个连接PSCache的大小 spring.datasource.poolPreparedStatements: true spring.datasource.maxPoolPreparedStatementPerConnectionSize: 20 #通过connectionProperties属性来打开mergeSql功能；慢SQL记录 #connectionProperties: druid.stat.mergeSql=true; druid.stat.slowSqlMillis=5000 spring.datasource.minIdle: 1 spring.datasource.minEvictableIdleTimeMillis: 3 spring.datasource.timeBetweenEvictionRunsMillis: 6000000000 spring.datasource.validationQuery: select 1 from dual spring.datasource.testWhileIdle: true spring.datasource.testOnBorrow: false spring.datasource.testOnReturn: false #配置监控统计拦截的filters，去掉后监控界面sql将无法统计,'wall'用于防火墙 spring.datasource.filters: stat, wall, logback

3.配置bean

package com.example.boottest.config; 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; @Configuration public class DruidConfiguration {@Bean @ConfigurationProperties(prefix = "spring.datasource") public DruidDataSource druidDataSource(){ DruidDataSource druidDataSource = new DruidDataSource(); return druidDataSource; }/** * 配置访问 druid 监控 */ @Bean public ServletRegistrationBean druidStateViewServlet(){ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*"); //初始化参数 initParamsservletRegistrationBean.addInitParameter("allow",""); //添加ip黑名单 servletRegistrationBean.addInitParameter("deny",""); //设置控制台管理用户 servletRegistrationBean.addInitParameter("loginUsername","druid"); servletRegistrationBean.addInitParameter("loginPassword","123456"); //是否可以重置数据 servletRegistrationBean.addInitParameter("resetEnable","false"); return servletRegistrationBean; }public FilterRegistrationBean statFilter(){ //创建过滤器 FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter()); //设置过滤器路径 filterRegistrationBean.addUrlPatterns("/*"); //忽略过滤的形式 filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico"); return filterRegistrationBean; }}
