1.修改pom.xml
MySQL mysql-connector-java com.alibaba druid 1.0.26
增加上面的配置。
2.编辑配置数据源代码
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; } /** * 注册一个StatViewServlet * @return */ @Bean public ServletRegistrationBean druidStatViewServlet(){ //org.springframework.boot.context.embedded.ServletRegistrationBean提供类的进行注册. ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*"); //添加初始化参数:initParams //白名单: servletRegistrationBean.addInitParameter("allow","127.0.0.1,192.168.31.77"); //IP黑名单 (存在共同时,deny优先于allow) : 如果满足deny的话提示:Sorry, you are not permitted to view this page. servletRegistrationBean.addInitParameter("deny","192.168.1.73"); //登录查看信息的账号密码. servletRegistrationBean.addInitParameter("loginUsername","admin"); servletRegistrationBean.addInitParameter("loginPassword","123456"); //是否能够重置数据. servletRegistrationBean.addInitParameter("resetEnable","false"); return servletRegistrationBean; } /** * 注册一个:filterRegistrationBean * @return */ @Bean public FilterRegistrationBean druidStatFilter(){ FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter()); //添加过滤规则. 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.编写配置文件 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 #-------------------------- # 下面为连接池的补充设置,应用到上面所有数据源中 # 初始化大小,最小,最大 spring.datasource.initialSize=5 spring.datasource.minIdle=5 spring.datasource.maxActive=50 # 配置获取连接等待超时的时间 spring.datasource.maxWait=60000 # 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒 spring.datasource.timeBetweenEvictionRunsMillis=60000 # 配置一个连接在池中最小生存的时间,单位是毫秒 spring.datasource.minEvictableIdleTimeMillis=300000 spring.datasource.validationQuery=SELECT 1 spring.datasource.testWhileIdle=true spring.datasource.testOnBorrow=false spring.datasource.testOnReturn=false # 打开PSCache,并且指定每个连接上PSCache的大小 spring.datasource.poolPreparedStatements=false #spring.datasource.maxPoolPreparedStatementPerConnectionSize=20 # 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.filters=stat,wall,log4j spring.datasource.filters=stat # 通过connectProperties属性来打开mergeSql功能;慢SQL记录 spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000 # 合并多个DruidDataSource的监控数据 #spring.datasource.useGlobalDataSourceStat=true
