## 配置使用Druid数据库连接池 ##

### 添加依赖 ###

*  Gradle

compile('com.alibaba:druid-spring-boot-starter:${version}')

*  Maven

<groupId>com.alibaba</groupId>
        <artifactId>druid</artifactId>
        <version>${version}</version>

### 配置数据库连接 ###

> 数据库配置和默认配置基本一样，按照正常配置就可以，具体可以参考[https://github.com/alibaba/druid/blob/master/druid-spring-boot-starter/README.md][https_github.com_alibaba_druid_blob_master_druid-spring-boot-starter_README.md]

*  JDBC 配置

spring.datasource.druid.url= # 或spring.datasource.url= 
    spring.datasource.druid.username= # 或spring.datasource.username=
    spring.datasource.druid.password= # 或spring.datasource.password=
    spring.datasource.druid.driver-class-name= #或 spring.datasource.driver-class-name=

*  连接池配置

spring.datasource.druid.initial-size=
    spring.datasource.druid.max-active=
    spring.datasource.druid.min-idle=
    spring.datasource.druid.max-wait=
    spring.datasource.druid.pool-prepared-statements=
    spring.datasource.druid.max-pool-prepared-statement-per-connection-size= 
    spring.datasource.druid.max-open-prepared-statements= #和上面的等价
    spring.datasource.druid.validation-query=
    spring.datasource.druid.validation-query-timeout=
    spring.datasource.druid.test-on-borrow=
    spring.datasource.druid.test-on-return=
    spring.datasource.druid.test-while-idle=
    spring.datasource.druid.time-between-eviction-runs-millis=
    spring.datasource.druid.min-evictable-idle-time-millis=
    spring.datasource.druid.max-evictable-idle-time-millis=
    spring.datasource.druid.filters= #配置多个英文逗号分隔
    ....//more

*  监控配置

# WebStatFilter配置，说明请参考Druid Wiki，配置_配置WebStatFilter
    spring.datasource.druid.web-stat-filter.enabled= #是否启用StatFilter默认值true
    spring.datasource.druid.web-stat-filter.url-pattern=
    spring.datasource.druid.web-stat-filter.exclusions=
    spring.datasource.druid.web-stat-filter.session-stat-enable=
    spring.datasource.druid.web-stat-filter.session-stat-max-count=
    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=
    
    # StatViewServlet配置，说明请参考Druid Wiki，配置_StatViewServlet配置
    spring.datasource.druid.stat-view-servlet.enabled= #是否启用StatViewServlet默认值true
    spring.datasource.druid.stat-view-servlet.url-pattern=
    spring.datasource.druid.stat-view-servlet.reset-enable=
    spring.datasource.druid.stat-view-servlet.login-username=
    spring.datasource.druid.stat-view-servlet.login-password=
    spring.datasource.druid.stat-view-servlet.allow=
    spring.datasource.druid.stat-view-servlet.deny=
    
    # Spring监控配置，说明请参考Druid Github Wiki，配置_Druid和Spring关联监控配置
    spring.datasource.druid.aop-patterns= # Spring监控AOP切入点，如x.y.z.service.*,配置多个英文逗号分隔
    # 如果spring.datasource.druid.aop-patterns要代理的类没有定义interface请设置spring.aop.proxy-target-class=true

> 配置好了之后启动应用就可以正常使用了，查看统计信息可以访问 [http://localhost:8080/druid/index.html][http_localhost_8080_druid_index.html]
