SpringBoot整合Druid数据库连接池的方法

SpringBoot整合Druid数据库连接池的方法

一，Druid是什么？

Druid是java语言中最好的数据库连接池。Druid能够提供强大的监控和扩展功能。

二， 在哪里下载druid

maven中央仓库: http://central.maven.org/maven2/com/alibaba/druid/

三， 怎么获取Druid的源码

Druid是一个开源项目，源码托管在github上，源代码仓库地址是 https://github.com/alibaba/druid。同时每次Druid发布正式版本和快照的时候，都会把源码打包，你可以从上面的下载地址中找到相关版本的源码

配置JdbcConfig

package zhw.example.zhw.loginModule.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;

import java.util.Collections;

import java.util.HashMap;

import java.util.Map;

@Configuration

public class JdbcConfig {

@ConfigurationProperties(prefix = "spring.datasource")

@Bean

public DataSource dataSource(){

return new DruidDataSource();

}

/**

* 配置Druid监控

*

* @return StatViewServlet

*/

@Bean

public ServletRegistrationBean servletRegistrationBean() {

ServletRegistrationBean bean = new ServletRegistrationBean<>(new StatViewServlet(), "/druid/*");

Map map = new HashMap<>();

//访问的用户名密码

map.put(StatViewServlet.PARAM_NAME_USERNAME, "root");

map.put(StatViewServlet.PARAM_NAME_PASSWORD, "root");

//允许访问的ip，默认是所有ip

map.put(StatViewServlet.PARAM_NAME_ALLOW, "");

//禁止访问的ip

map.put(StatViewServlet.PARAM_NAME_DENY, "192.168.1.1");

bean.setInitParameters(map);

return bean;

}

/**

* 配置一个监控的filter

*

* @return WebStatFilter

*/

@Bean

public FilterRegistrationBean filterRegistrationBean() {

FilterRegistrationBean bean = new FilterRegistrationBean<>();

bean.setFilter(new WebStatFilter());

Map map = new HashMap<>();

//移除这些监听

map.put(WebStatFilter.PARAM_NAME_EXCLUSIONS, "*.js,*.css,/druid/*,*.gif,*.jpg,*.png");

bean.setInitParameters(map);

//拦截所有请求，全部都要走druid监听

bean.setUrlPatterns(Collections.singletonList("/*"));

return bean;

}

}

测试配置url白名单

如果工程中配置了Apache Shiro，需要在配置类中添加白名单
