SpringBoot2.0 集成Druid

一、引入依赖

 <!--druid-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.13</version>
        </dependency>

二、在properties文件中添加配置-我这里其实就只加了一行（spring.datasource.druid.filters=stat,wall）

server.port=8080
server.servlet.context-path=/

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/rbac?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true&autoReconnect=true&failOverReadOnly=false&&useSSL=false&serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=12345
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.druid.filters=stat,wall
# stat：Druid内置提供一个StatFilter,用于统计监控信息。
# wall：Druid防御SQL注入攻击的WallFilter就是通过Druid的SQL Parser分析。Druid提供的SQL Parser可以在JDBC层拦截SQL做相应处理，比如说分库分表、审计等。
# log4j：这个就是日志记录的功能，可以把sql语句打印到log4j供排查问题。
#spring.datasource.druid.filters=stat,wall,log4j

三、写配置类

package com.kf.config;

import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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;

@Configuration
public class DruidConfig {

    private static final Logger logger = LoggerFactory.getLogger(DruidConfig.class);

    @Bean
    public ServletRegistrationBean druidServlet() {
        logger.info("init Druid Servlet Configuration ");
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        // IP白名单
        //servletRegistrationBean.addInitParameter("allow", "*.");
        // IP黑名单(共同存在时，deny优先于allow)
        //servletRegistrationBean.addInitParameter("deny", "139.158.xxx.xxx");
        //控制台管理用户
        servletRegistrationBean.addInitParameter("loginUsername", "admin");
        servletRegistrationBean.addInitParameter("loginPassword", "admin");
        //是否能够重置数据 禁用HTML页面上的“Reset All”功能
        servletRegistrationBean.addInitParameter("resetEnable", "true");
        return servletRegistrationBean;
    }

    /**
     * 注册一个：filterRegistrationBean
     *  没有这个类的话，则URI监控、session监控、web应用都出不来
     * @return
     */
    @Bean
    public FilterRegistrationBean druidStatFilter2(){
        System.out.println("filterRegistrationBean configure start.");
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
        //添加过滤规则.
        filterRegistrationBean.addUrlPatterns("/*");
        //添加不需要忽略的格式信息.
        filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
        return filterRegistrationBean;
    }


}
