篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Spring Boot 整合 Druid && 配置数据源监控相关的知识,希望对你有一定的参考价值。
1. 导入 Druid 包
<dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.12</version> </dependency>
2. application 配置文件配置 druid 数据源
spring: datasource: username: root password: root url: jdbc:mysql://127.0.0.1:3306/springboot?serverTimezone=GMT%2B8 driver-class-name: com.mysql.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource # 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 initialSize: 1 minIdle: 3 maxActive: 20 # 配置获取连接等待超时的时间 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 timeBetweenEvictionRunsMillis: 60000 # 配置一个连接在池中最小生存的时间,单位是毫秒 minEvictableIdleTimeMillis: 30000 #validationQuery: select ‘x‘ testWhileIdle: false testOnBorrow: false testOnReturn: false # 打开PSCache,并且指定每个连接上PSCache的大小 poolPreparedStatements: true 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 filters: stat,wall,slf4j # 通过connectProperties属性来打开mergeSql功能;慢SQL记录 connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000 # 合并多个DruidDataSource的监控数据 useGlobalDataSourceStat: true

/*** * Druid 配置类 */ @Configuration public class DruidConfig { /** * 绑定Druid数据源 * @return */ @ConfigurationProperties(prefix = "spring.datasource") @Bean public DataSource druid(){ return new DruidDataSource(); } // 配置druid的监控 @Bean public ServletRegistrationBean statViewServlet(){ ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*"); Map<String,String> map = new HashMap<>(); map.put("loginUsername","admin"); map.put("loginPassword","admin"); map.put("allow",""); servletRegistrationBean.setInitParameters(map); return servletRegistrationBean; } public FilterRegistrationBean WebStatFilter(){ FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(); filterRegistrationBean.setFilter(new WebStatFilter()); Map<String,String> map = new HashMap<>(); map.put("exclusions","*.js,*,css,/druid/*"); filterRegistrationBean.setInitParameters(map); filterRegistrationBean.setUrlPatterns(Arrays.asList("/*")); return filterRegistrationBean; } }
