druid 是阿里開源的數據庫連接池。

開發時整合? ?druid 數據源過程。

1.修改pom.xml

<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.0.26</version></dependency>

增加上面的配置。

2.編輯配置數據源代碼。

package com.neo.conf;import javax.sql.DataSource;import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.boot.web.servlet.FilterRegistrationBean; import org.springframework.boot.web.servlet.ServletRegistrationBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.PropertySource;import com.alibaba.druid.pool.DruidDataSource; import com.alibaba.druid.support.http.StatViewServlet; import com.alibaba.druid.support.http.WebStatFilter;@Configuration @ConfigurationProperties(value = "classpath:druid.properties") public class DruidConfiguration {@Bean(destroyMethod = "close", initMethod = "init")@ConfigurationProperties(prefix = "spring.datasource")public DataSource druidDataSource() {DruidDataSource druidDataSource = new DruidDataSource();return druidDataSource;}/*** 注冊一個StatViewServlet* @return*/@Beanpublic ServletRegistrationBean druidStatViewServlet(){//org.springframework.boot.context.embedded.ServletRegistrationBean提供類的進行注冊.ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");//添加初始化參數：initParams//白名單：servletRegistrationBean.addInitParameter("allow","127.0.0.1,192.168.31.77");//IP黑名單 (存在共同時，deny優先于allow) : 如果滿足deny的話提示:Sorry, you are not permitted to view this page.servletRegistrationBean.addInitParameter("deny","192.168.1.73");//登錄查看信息的賬號密碼.servletRegistrationBean.addInitParameter("loginUsername","admin");servletRegistrationBean.addInitParameter("loginPassword","123456");//是否能夠重置數據.servletRegistrationBean.addInitParameter("resetEnable","false");return servletRegistrationBean;}/*** 注冊一個：filterRegistrationBean* @return*/@Beanpublic FilterRegistrationBean druidStatFilter(){FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());//添加過濾規則.filterRegistrationBean.addUrlPatterns("/*");//添加不需要忽略的格式信息.filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");return filterRegistrationBean;} }

3.編寫配置文件 druid.properties

spring.datasource.driverClassName=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/mycine?useUnicode=true&characterEncoding=utf8&autoReconnect=true spring.datasource.username=root spring.datasource.password=root #-------------------------- # 下面為連接池的補充設置，應用到上面所有數據源中 # 初始化大小，最小，最大 spring.datasource.initialSize=5 spring.datasource.minIdle=5 spring.datasource.maxActive=50 # 配置獲取連接等待超時的時間 spring.datasource.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，單位是毫秒 spring.datasource.timeBetweenEvictionRunsMillis=60000 # 配置一個連接在池中最小生存的時間，單位是毫秒 spring.datasource.minEvictableIdleTimeMillis=300000 spring.datasource.validationQuery=SELECT 1 spring.datasource.testWhileIdle=true spring.datasource.testOnBorrow=false spring.datasource.testOnReturn=false # 打開PSCache，并且指定每個連接上PSCache的大小 spring.datasource.poolPreparedStatements=false #spring.datasource.maxPoolPreparedStatementPerConnectionSize=20 # 配置監控統計攔截的filters，去掉后監控界面sql無法統計，'wall'用于防火墻 #spring.datasource.filters=stat,wall,log4j spring.datasource.filters=stat # 通過connectProperties屬性來打開mergeSql功能；慢SQL記錄 spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000 # 合并多個DruidDataSource的監控數據 #spring.datasource.useGlobalDataSourceStat=true

4.啟動程序查看效果
