3.driud配置类

package com.lyj.cache.config;

import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;

/**
 * druid监控控制台配置
 */
@Configuration
public class DruidConfig {
     
    // 主要实现web监控的配置处理
    @Bean
    public ServletRegistrationBean druidServlet() {
     
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        //servletRegistrationBean.addInitParameter("allow", "127.0.0.1,192.168.202.233");//白名单
        //servletRegistrationBean.addInitParameter("deny", "192.168.202.234");//黑名单
        servletRegistrationBean.addInitParameter("loginUsername", "root");//用户名
        servletRegistrationBean.addInitParameter("loginPassword", "root");//密码
        servletRegistrationBean.addInitParameter("resetEnable", "false");//是否可以重置数据源
        return servletRegistrationBean;

    }

    //过滤
    @Bean
    public FilterRegistrationBean filterRegistrationBean() {
     
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        filterRegistrationBean.setFilter(new WebStatFilter());
        filterRegistrationBean.addUrlPatterns("/*");//所有请求进行监控处理
        filterRegistrationBean.addInitParameter("exclusions", "/static/*,*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");//排除
        return filterRegistrationBean;
    }

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource druidDataSource() {
     
        return new DruidDataSource();
    }
}
