SpringBoot 2.1.1.RELEASE 集成Druid
详情：
http://www.qchcloud.cn/system/article/show/68
配置依赖：
mysql
mysql-connector-java
com.alibaba
druid
1.1.4
配置applicaton.properties
spring.datasource.driverClassName = com.mysql.cj.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/iot?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username = root
spring.datasource.password = 1234
### log4j配置
logging.config=classpath:log4j2.xml
### 数据源类别
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
### 初始化大小，最小，最大
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
### 配置获取连接等待超时的时间，单位是毫秒
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 FROM DUAL
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=true
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
### 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
配置监控：
@Configuration
public class DruidConfiguration {
@Bean
public ServletRegistrationBean druidStatViewServle(){
//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");
//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","192.168.1.7");
//登录查看信息的账号和密码.
servletRegistrationBean.addInitParameter("loginUsername","admin");
servletRegistrationBean.addInitParameter("loginPassword","123456");
//是否能够重置数据.
servletRegistrationBean.addInitParameter("resetEnable","false");
return servletRegistrationBean;
}
@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;
}
}
