DruidConfig配置类

@Configuration
public class DruidConfig {
    @Bean
    ServletRegistrationBean regisDruid() {
        //固定写法，配置访问路径
        ServletRegistrationBean<StatViewServlet> bean = new ServletRegistrationBean<>(new StatViewServlet(), "/druid/*");
        //配置登录信息，固定写法
        HashMap<String, String> initParams = new HashMap<>();
        //账号和密码的key是固定的
        initParams.put("loginUsername", "admin");
        initParams.put("loginPassword", "xxx");

        //允许谁可以访问
        initParams.put("allow", "127.0.0.1");
        bean.setInitParameters(initParams);
        return bean;
    }
}
