1、配置application.yml

spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://192.168.93.101:3306/jdbc_test?useUnicode=true&characterEncoding=utf-8&relaxAutoCommit=true&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true
    driver-class-name: com.mysql.cj.jdbc.Driver
    initialization-mode: always
#   指定数据源的类型
    type: com.alibaba.druid.pool.DruidDataSource
#    schema:
#        - classpath:employee.sql

    # 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

2、进行测试数据源

@Test
    void contextLoads() throws SQLException {
        System.out.println(dataSource.getClass()); //class com.alibaba.druid.pool.DruidDataSource

3、自定义

DruidConfig配置类

@ConfigurationProperties(prefix="spring.datasource") //来获取application.yml配置的属性

@Configuration
public class DruidConfig {

    @ConfigurationProperties(prefix="spring.datasource") //来获取application.yml配置的属性
    @Bean
    public DruidDataSource druidDataSource(){
        return new DruidDataSource();
    }

4、配置一个管理后台的servlet

查看源码进行设置

//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<String,String> initParams = new HashMap<>();
        initParams.put("loginUsername", "admin");
        initParams.put("loginPassword", "1234");
        initParams.put("allow", ""); //默认运行所有访问
        initParams.put("deny", "192.168.0.105");
        bean.setInitParameters(initParams);
        return bean;
    }

5、配置一个web监控的filter

//配置一个web监控的filter
    public FilterRegistrationBean webStatFilter() {
        FilterRegistrationBean bean = new FilterRegistrationBean();
        bean.setFilter(new WebStatFilter());
        Map<String,String> initParams = new HashMap<>();

        initParams.put("exclusions", "*.js, *.css, *.images, /druid/*");
        bean.setInitParameters(initParams);

        bean.setUrlPatterns(Arrays.asList("/*"));
        return bean;
    }

6、启动，访问http://localhost:8080/druid/
