spring boot 配置 druid

一:引包

com.alibaba
druid
1.1.9

二:配置config

注意DruidConfiguration文件要和springBoot启动类 在同一目录层级

import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
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 DruidConfiguration {

@Bean
public ServletRegistrationBean statViewServlet(){
//创建servlet注册实体
ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
//设置ip白名单
servletRegistrationBean.addInitParameter("allow","127.0.0.1");
//设置ip黑名单，如果allow与deny共同存在时,deny优先于allow
servletRegistrationBean.addInitParameter("deny","192.168.0.19");
//设置控制台管理用户
servletRegistrationBean.addInitParameter("loginUsername","druid");
servletRegistrationBean.addInitParameter("loginPassword","123456");
//是否可以重置数据
servletRegistrationBean.addInitParameter("resetEnable","false");
return servletRegistrationBean;
}

@Bean
public FilterRegistrationBean statFilter(){
    //创建过滤器
    FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
    //设置过滤器过滤路径
    filterRegistrationBean.addUrlPatterns("/*");
    //忽略过滤的形式
    filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
    return filterRegistrationBean;
    }
}

三:配置application.properties

SpringBoot 1.5版本 默认使用的是tomcat连接池,所有有别的连接池,最好是注释掉  改成自己的 数据库配置 

#mysql#spring.datasource.url=jdbc:mysql://192.168.88.160:3306/sx_exam?useSSL=false&useUnicode=true&characterEncoding=utf-8
spring.datasource.url=jdbc:mysql://localhost:3306/test?useSSL=false&useUnicode=true&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name: com.mysql.jdbc.Driver

#druid连接池spring.datasource.type: com.alibaba.druid.pool.DruidDataSource#最大活跃数spring.datasource.maxActive: 20#初始化数量spring.datasource.initialSize: 1#最大连接等待超时时间spring.datasource.maxWait: 60000#打开PSCache，并且指定每个连接PSCache的大小spring.datasource.poolPreparedStatements: true
spring.datasource.maxPoolPreparedStatementPerConnectionSize: 20#通过connectionProperties属性来打开mergeSql功能；慢SQL记录#connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000spring.datasource.minIdle: 1spring.datasource.timeBetweenEvictionRunsMillis: 60000spring.datasource.minEvictableIdleTimeMillis: 300000spring.datasource.validationQuery: select 1 from dual
spring.datasource.testWhileIdle: true
spring.datasource.testOnBorrow: false
spring.datasource.testOnReturn: false
#配置监控统计拦截的filters，去掉后监控界面sql将无法统计,'wall'用于防火墙filters: stat, wall, log4j

四:访问

http://127.0.0.1:8080/druid/login.html 

账号密码在config类里

补充知识：

首先我们得下载一个druid-1.0.16.jar的包

其次键入命令 java -cp druid-1.0.16.jar com.alibaba.druid.filter.config.ConfigTools your_password

这时候会生成privatekey，publickey，以及password，相关的截图如下

 如果要生成  用 密码 代替 root  就可以了。
