如何配置Spring Boot集成Druid连接池？

本文共计635个文字，预计阅读时间需要3分钟。

在开发项目中，若数据库选用MySQL，高概率会使用Druid连接池。以下是如何在Spring Boot中集成Druid的步骤：

1. 集成Druid和Spring Boot： - Spring Boot版本：2.1.9 - Druid版本：1.1.10

2. 示例项目地址： - GitHub地址：[项目链接]

3. 集成Druid配置： - 在`pom.xml`中添加以下依赖：

xml org.springframework.boot spring-boot-starter-jdbc com.alibaba druid-spring-boot-starter 1.1.10

- 配置数据库连接和Druid属性，在`application.properties`或`application.yml`中：

properties数据库配置spring.datasource.url=jdbc:mysql://localhost:3306/your_database?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTCspring.datasource.username=rootspring.datasource.password=your_passwordspring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

Druid配置spring.datasource.type=com.alibaba.druid.pool.DruidDataSourcespring.datasource.druid.initial-size=5spring.datasource.druid.min-idle=5spring.datasource.druid.max-active=20spring.datasource.druid.max-wait=60000spring.datasource.druid.time-between-eviction-runs-millis=60000spring.datasource.druid.min-evictable-idle-time-millis=300000spring.datasource.druid.validation-query=SELECT 1 FROM DUALspring.datasource.druid.test-while-idle=truespring.datasource.druid.test-on-borrow=falsespring.datasource.druid.test-on-return=falsespring.datasource.druid.pool-prepared-statements=truespring.datasource.druid.max-open-prepared-statements=20spring.datasource.druid.remove-abandoned=truespring.datasource.druid.remove-abandoned-timeout=1800spring.datasource.druid.log-abandoned=true

以上是在Spring Boot项目中集成Druid的简要步骤和配置。

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.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; } }
