重写配置类

@Configuration
public class DruidConfig {
    /**
     * 配置监控服务器
     * @return
     */
    @Bean
    public ServletRegistrationBean statViewServle(){
        //后台监控地址
        ServletRegistrationBean servletRegistrationBean=new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
        servletRegistrationBean.addInitParameter("allow","192.168.3.54,192.168.3.45，127.0.0.1");
        servletRegistrationBean.addInitParameter("deny","192.168.3.102");
        //设置没登录用户名以及密码
        servletRegistrationBean.addInitParameter("loginUsername","druid");
        servletRegistrationBean.addInitParameter("loginPassword","123456");
        servletRegistrationBean.addInitParameter("resetEnable","false");
        return servletRegistrationBean;
    }
    @Bean
    public FilterRegistrationBean filterStat(){
        FilterRegistrationBean filterRegistrationBean=new FilterRegistrationBean(new WebStatFilter());
        filterRegistrationBean.addUrlPatterns("/*");
        filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.png,*.jpg,*.css,*.ico,/druid/*");
        return filterRegistrationBean;
    }
}

在主类中允许自动配置

可以加入@EnableAutoConfiguration或者@SpringBootApplication

@SpringBootApplication注解等价于以默认属性使用@Configuration，@EnableAutoConfiguration和@ComponentScan

效果

在本项目路径下的/druid/index.html页面下可以利用自己配置的而登陆名以及密码进行登录！
