application.yml

spring:
  datasource:
#   数据源基本配置
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/estore?useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
    type: com.alibaba.druid.pool.DruidDataSource

    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,stat
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
# 端口
server:
  port: 8080
  servlet:
    context-path: /szs

导入Druid数据源

@Configuration
public class DruidConfig {
    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druid(){
        return new DruidDataSource();
    }

    //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<>(10);
        initParams.put("loginUsername", "admin");
        initParams.put("loginPassword", "123456");
        //默认允许所有的进行访问
        initParams.put("allow", "");

        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,String> initParams = new HashMap<>(6);
        initParams.put("exclusions","*.js,*.css,/druid/*");
        bean.setInitParameters(initParams);

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

}

进行登录,如图,我配置了context-path: /szs;

进入后输入 " public ServletRegistrationBean statViewServlet()"中的loginUsername和loginPassword即可进入.
