导入Druid数据源
<!--引入druid数据源-->
<!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.10</version>
</dependency>
 application.yaml文件

spring:
datasource:
data-username: xxxx
data-password: xxxxx
url: jdbc:mysql://localhost:3306/xxxxdb
driver-class-name: com.mysql.cj.jdbc.Driver
# 切换数据源
type: com.alibaba.druid.pool.DruidDataSource

# 数据源其他配置
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
# 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
maxPoolPreparedStatementPerConnectionSize: 20
useGlobalDataSourceStat: true
connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
 

配置数据源监控
@Configuration
public class DruidConfig

@ConfigurationProperties(prefix = "spring.datasource")
@Bean
public DataSource druid()
return new DruidDataSource(http://www.my516.com);


//配置监控
//1.配置一个管理后台的servlet
@Bean
public ServletRegistrationBean staViewServlet()
ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
Map<String,Object> initParams = new HashMap<>();
initParams.put("loginUsername", "admin");//自己编写
initParams.put("loginPassword", "123456");//自己编写
initParams.put("allow", "");
// initParams.put("deny", "");
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<String,Object> initParams = new HashMap<>();
initParams.put("exclusions", "*.js,*.css,/druid/*");

bean.setInitParameters(initParams);
bean.setUrlPatterns(Arrays.asList("/*"));

return bean;
