这篇文章主要介绍了springboot整合druid连接池的步骤，帮助大家更好的理解和学习springboot框架，感兴趣的朋友可以了解下
使用springboot默认的连接池
导入springboot data-jdbc依赖
org.springframework.bootspring-boot-starter-data-jdbc
配置文件配置连接池
spring: datasource: username: root password: 5201314 url: jdbc:mysql:///jqmb?serverTimezone=UTC driver-class-name: com.mysql.cj.jdbc.Driver
springboot默认的连接池
@Autowired DataSource dataSource; @Test void contextLoads() { System.out.println(dataSource.getClass()); System.out.println("____________________________________"); }
使用连接池druid
导入druid依赖
com.alibabadruid1.0.18
配置文件配置druid的属性
spring: datasource: username: root password: 5201314 url: jdbc:mysql:///jqmb?serverTimezone=UTC driver-class-name: com.mysql.cj.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource initialSize: 5 minIdle: 5 maxActive: 20 maxWait: 60000 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: SELECT 1 FROM DUAL testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true filters: stat,wall,log4j maxPoolPreparedStatementPerConnection<strong style="color:transparent">来源gaodaima#com搞(代@码网</strong>Size: 20 useGlobalDataSourceStat: true connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
配置类中对druid属性进行绑定
@Configuration public class DataSource_Druid_Configure { @ConfigurationProperties(prefix = "spring.datasource") @Bean public DruidDataSource getDataSour(){ return new DruidDataSource(); }
配置Druid的监控后台
//配置Druid的监控 //1、配置一个管理后台的Servlet @Bean public ServletRegistrationBean statViewServlet(){ ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*"); Map initParams = new HashMap(); initParams.put("loginUsername","admin");//登录用户名 initParams.put("loginPassword","123456");//登录密码 initParams.put("allow","");//默认就是允许所有访问 initParams.put("deny","192.168.15.21");//拒绝访问 bean.setInitParameters(initParams); return bean; } //2、配置一个web监控的filter @Bean public FilterRegistrationBean webStatFilter(){ FilterRegistrationBean bean = new FilterRegistrationBean(); bean.setFilter(new WebStatFilter()); Map initParams = new HashMap(); initParams.put("exclusions","*.js,*.css,/druid/*"); bean.setInitParameters(initParams); bean.setUrlPatterns(Arrays.asList("/*")); return bean; }
访问http://localhost:8090/druid/login.html
如果sql监控失效需要导入log4j 依赖
log4jlog4j1.2.17
