SpringBoot-配置Druid-yml方式

1.首先導入依賴

<properties>
    <java.version>1.8</java.version>
    <mysql.version>5.1.47</mysql.version>
    <druid.version>1.1.14</druid.version>
</properties>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>org.junit.vintage</groupId>
                <artifactId>junit-vintage-engine</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jdbc</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>${mysql.version}</version>
    </dependency>

    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid-spring-boot-starter</artifactId>
        <version>${druid.version}</version>
    </dependency>
</dependencies>

2.application.yml配置文件

spring:
  datasource:
    url: jdbc:mysql://ip:port/dbname?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8&useSSL=false
    username: root
    password: password
    driver-class-name: com.mysql.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      #初始化大小
      initialSize: 5
      #最小值
      minIdle: 5
      #最大值
      maxActive: 20
      #最大等待時間，配置獲取連接等待超時，時間單位都是毫秒ms
      maxWait: 60000
      #配置間隔多久才進行一次檢測，檢測需要關閉的空閑連接
      timeBetweenEvictionRunsMillis: 60000
      #配置一個連接在池中最小生存的時間
      minEvictableIdleTimeMillis: 300000
      validationQuery: SELECT 1 FROM DUAL
      testWhileIdle: true
      testOnBorrow: false
      testOnReturn: false
      poolPreparedStatements: true
      # 配置監控統計攔截的filters，去掉后監控界面sql無法統計，
      #'wall'用於防火牆，SpringBoot中沒有log4j，我改成了log4j2
      filters: stat,wall,log4j2
      #最大PSCache連接
      maxPoolPreparedStatementPerConnectionSize: 20
      useGlobalDataSourceStat: true
      # 通過connectProperties屬性來打開mergeSql功能；慢SQL記錄
      connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
      # 配置StatFilter
      web-stat-filter:
        #默認為false，設置為true啟動
        enabled: true
        url-pattern: "/*"
        exclusions: "*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*"
      #配置StatViewServlet
      stat-view-servlet:
        url-pattern: "/druid/*"
        #允許那些ip
        allow: 127.0.0.1
        login-username: admin
        login-password: 123456
        #禁止那些ip
        deny: 192.168.1.102
        #是否可以重置
        reset-enable: true
        #啟用
        enabled: true

3.然后輸入你配置的url、賬號、密碼進入這里(比如輸入http://localhost:8080/druid)
