集成Druid连接池

spring boot默认是使用tomcat jdbc连接池

application.properties注释掉spring.datasource配置

引入依赖

<!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.1.8</version>
</dependency>

配置datasource类

 1 package com.xiaoping.house.config;
 2 
 3 import com.alibaba.druid.filter.Filter;
 4 import com.alibaba.druid.filter.stat.StatFilter;
 5 import com.alibaba.druid.pool.DruidDataSource;
 6 import com.alibaba.druid.support.http.StatViewServlet;
 7 import com.google.common.collect.Lists;
 8 import org.springframework.boot.context.properties.ConfigurationProperties;
 9 import org.springframework.boot.web.servlet.ServletRegistrationBean;
10 import org.springframework.context.annotation.Bean;
11 import org.springframework.context.annotation.Configuration;
12 
13 @Configuration
14 public class DruidConfig {
15     //绑定application.properties的spring.druid的属性为datasource
16     @ConfigurationProperties(prefix = "spring.druid")
17     @Bean(initMethod = "init",destroyMethod = "close")
18     public DruidDataSource dataSource(){
19         DruidDataSource druidDataSource = new DruidDataSource();
20         druidDataSource.setProxyFilters(Lists.newArrayList(statFilter()));
21         return druidDataSource;
22     }
23     //慢日志输出
24     @Bean
25     public Filter statFilter(){
26         StatFilter statFilter = new StatFilter();
27         statFilter.setSlowSqlMillis(1);
28         statFilter.setLogSlowSql(true);
29         statFilter.setMergeSql(true);
30         return statFilter;
31     }
32     //监控:localhost:8080/druid
33     @Bean
34     public ServletRegistrationBean servletRegistrationBean(){
35         return new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
36     }
37 }

application.properties配置相关属性值

 1 spring.druid.driverClassName=com.mysql.jdbc.Driver
 2 spring.druid.url=jdbc:mysql://localhost:33062/test?characterEncoding=UTF-8
 3 spring.druid.username=root
 4 spring.druid.password=766774
 5 spring.druid.maxActive=30
 6 spring.druid.minIdle=5
 7 spring.druid.maxWait=10000
 8 #解决Mysql8小时的问题
 9 spring.druid.validationQuery=SELECT 'x'
10 spring.druid.minEvictableIdleTimeMillis=300000
11 spring.druid.timeBetweenEvictionRunsMillis=60000

监控可以通过访问：http://localhost:8080/druid/
