SpringBoot整合Mybatis（二）使用Druid数据库连接池

在上一篇文章 SpringBoot整合Mybatis（一）中，进行了SpringBoot与Mybatis的整合，本文将在其基础引入对数据库连接池Druid的支持。

准备

整合

1、添加依赖

druid-spring-boot-starter:1.1.3

在pom.xml中添加对Druid的依赖

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.3</version>
</dependency>

2、配置

• Druid数据源配置

spring.datasource.druid.initial-size=1
spring.datasource.druid.max-active=20
spring.datasource.druid.min-idle=1
spring.datasource.druid.max-wait=60000
spring.datasource.druid.pool-prepared-statements=true
spring.datasource.druid.max-pool-prepared-statement-per-connection-size= -1
spring.datasource.druid.test-on-borrow=false
spring.datasource.druid.test-on-return=false
spring.datasource.druid.test-while-idle=true
spring.datasource.druid.time-between-eviction-runs-millis=60000
spring.datasource.druid.min-evictable-idle-time-millis=300000
spring.datasource.druid.filters=stat

• WebStatFilter配置

spring.datasource.druid.web-stat-filter.enabled=true
spring.datasource.druid.web-stat-filter.url-pattern=/*
spring.datasource.druid.web-stat-filter.exclusions=*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*
spring.datasource.druid.web-stat-filter.session-stat-enable=false
spring.datasource.druid.web-stat-filter.session-stat-max-count=1000
spring.datasource.druid.web-stat-filter.principal-session-name=
spring.datasource.druid.web-stat-filter.principal-cookie-name=
spring.datasource.druid.web-stat-filter.profile-enable=true

• StatViewServlet配置

spring.datasource.druid.stat-view-servlet.enabled=true
spring.datasource.druid.stat-view-servlet.url-pattern=/druid/*
spring.datasource.druid.stat-view-servlet.reset-enable=true
spring.datasource.druid.stat-view-servlet.login-username=admin
spring.datasource.druid.stat-view-servlet.login-password=admin
spring.datasource.druid.stat-view-servlet.allow=
spring.datasource.druid.stat-view-servlet.deny=

• Spring关联监控配置，配置在service层

spring.datasource.druid.aop-patterns=com.demo.service

测试

1、登录Druid监控后台

启动应用后，访问 http://localhost:8080/druid/ 即可看到Druid监控后台的登录页面，登录帐号密码分别使用上面的StatViewServlet配置中的

spring.datasource.druid.stat-view-servlet.login-username=admin
spring.datasource.druid.stat-view-servlet.login-password=admin
