springboot中默认是使用的tomcat的连接池,如果我们想要第三方的连接池,我们这么配置呢?
首先在application.yml文件中注释掉之前数据库的配置,重新用druid的方式配置:
#spring: #datasource: # driver-class-name: com.mysql.jdbc.Driver # url: jdbc:mysql://127.0.0.1:3306/house #username: root #password: root mybatis.config-location = classpath:/mybatis/mybatis-config.xml spring.druid.url = jdbc:mysql://127.0.0.1:3306/house spring.druid.username = root spring.druid.password = root spring.druid.driverClassName = com.mysql.jdbc.Driver spring.druid.initialSize=5 spring.druid.minIdle=5 spring.druid.maxActive=20 spring.druid.maxWait=10000 spring.druid.timeBetweenEvictionRunsMillis=60000 spring.druid.minEvictableIdleTimeMillis=300000 spring.druid.validationQuery=SELECT 1 FROM DUAL spring.druid.testWhileIdle=true
在pom文件中配置依赖库:
<dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.8</version> </dependency> <dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>18.0</version> <!--特别注意这个地方版本也不能乱 --> </dependency>
新建DruidConfig配置文件:
@Configuration public class DruidConfig { @ConfigurationProperties(prefix="spring.druid") //将配置文件中spring.druid.*配置到DruidDataSource中 @Bean(initMethod="init",destroyMethod="close") public DruidDataSource dataSource(Filter statFilter) throws SQLException{ DruidDataSource dataSource = new DruidDataSource(); dataSource.setProxyFilters(Lists.newArrayList(statFilter())); return dataSource; } //配置慢连接过滤 @Bean public Filter statFilter(){ StatFilter filter = new StatFilter(); filter.setSlowSqlMillis(5000); filter.setLogSlowSql(true); filter.setMergeSql(true); return filter; } //添加监控,可以帮助我们分析慢sql和每个sql的执行时间 @Bean public ServletRegistrationBean servletRegistrationBean(){ return new ServletRegistrationBean(new StatViewServlet(), "/druid/*"); } }
然后启动项目,在浏览器中输入地址http://127.0.0.1:8080/user对数据库中的user表进行查询后,再访问http://127.0.0.1:8080/druid将会显示页面如下,可以对数据源、sql监控等进行查询:
