springboot+druid(使用druid-spring-boot-starter配置)

参考:

https://github.com/alibaba/druid/tree/master/druid-spring-boot-starter

1.基础配置:

添加依赖:

<project xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>alibaba-druid-test</groupId>
	<artifactId>alibaba-druid-test</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<!-- 继承默认值为Spring Boot -->
	<parent>
		<groupId> org.springframework.boot </groupId>
		<artifactId> spring-boot-starter-parent </artifactId>
		<version> 2.0.3.RELEASE </version>
	</parent>

	<dependencies>

		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>druid-spring-boot-starter</artifactId>
			<version>1.1.14</version>
		</dependency>

		<!-- 添加Web应用程序的典型依赖项 -->

			<artifactId> spring-boot-starter-web </artifactId>
		</dependency>

		<dependency>
			<groupId>org.mybatis.spring.boot</groupId>
			<artifactId>mybatis-spring-boot-starter</artifactId>
			<version>1.3.2</version>
		</dependency>

		<!-- mysql 依赖 -->
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
		</dependency>


		<dependency>

			<scope>true</scope>
		</dependency>



	</dependencies>
	<!-- 打包为可执行jar -->
	<build>
		<plugins>
			<plugin>
				<groupId> org.springframework.boot </groupId>
				<artifactId> spring-boot-maven-plugin </artifactId>

		</plugins>
	</build>




</project>

application.properties:

#Druid Spring Boot Starter 配置属性的名称完全遵照 Druid，你可以通过 Spring Boot 配置文件来配置Druid数据库连接池和监控，如果没有配置则使用默认值。
#JDBC 配置
#spring.datasource.druid.url= jdbc:mysql://localhost:3306/shiro?useUnicode=true&characterEncoding=utf-8&useSSL=false
#spring.datasource.druid.username= root
#spring.datasource.druid.password= 123456
#spring.datasource.druid.driver-class-name= com.mysql.jdbc.Driver

######################等同以上配置##########################
spring.datasource.url= jdbc:mysql://localhost:3306/shiro?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.username= root
spring.datasource.password= 123456
spring.datasource.driver-class-name= com.mysql.jdbc.Driver

到这里就配置完了,没错配置完了,就是这么骚,接下来运行项目检查下:
springboot+druid(使用druid-spring-boot-starter配置)

控制台出现以上信息,说明已经整合成功,接下来删除druid依赖重新运行项目,可以看到以下信息:
springboot+druid(使用druid-spring-boot-starter配置)
这时项目已经使用了springboot默认的数据库连接池,为什么添加依赖就能改变数据库连接池呢,我们来看看源码:

我们进入红框中DataSourceProperties,会发现以下信息:

通过上边的图可以发现druid-spring-boot-starter已经默认配置好了这些属性(spring.dataSource==spring.datasource.druid),你只需添加依赖即可,一切操作和以前一样处理

2.监控配置:

#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
spring.datasource.druid.filters= stat,wall

# WebStatFilter配置，说明请参考Druid Wiki，配置_配置WebStatFilter

到这里整合就完了,有什么不对请多多指导…
