SpringBoot三种方式配置Druid(包括纯配置文件配置)

编程

因为druid monitor 监控页面没做访问控制,下次一定记得,特收集了几种配置方式供参考!

记录一下在项目中用纯 YML(application.yml 或者 application.properties)文件、Java 代码配置 Bean 和注解三种方式配置 Alibaba Druid 用于监控或者查看 SQL 状况:

1. 纯配置文件 .yml 或者 .properties

(1)pom.xml 添加相关依赖

 

<!-- SPRINGBOOT WEB -->

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

<!-- SPRINGBOOT DRUID -->

<dependency>

<groupId>com.alibaba</groupId>

<artifactId>druid-spring-boot-starter</artifactId>

<version>1.1.10</version>

</dependency>

<!-- SPRINGBOOT JDBC -->

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-jdbc</artifactId>

</dependency>

<!-- MYSQL -->

<dependency>

<groupId>mysql</groupId>

<artifactId>mysql-connector-java</artifactId>

<scope>${mysql-connector-java.version}</scope>

</dependency>

<!-- LOG4J -->

<dependency>

<groupId>log4j</groupId>

<artifactId>log4j</artifactId>

<version>1.2.16</version>

<scope>compile</scope>

</dependency>

 

(2)配置 application.yml 或者 application.properties 文件,本次配置文件为 application.yml

 

spring:

# 数据源配置

datasource:

type: com.alibaba.druid.pool.DruidDataSource

   # MYSQL 5 驱动:com.mysql.jdbc.Driver,MYSQL 6+ 驱动:com.mysql.cj.jdbc.Driver

driver-class-name: com.mysql.cj.jdbc.Driver

url: jdbc:mysql://127.0.0.1:3306/test?autoReconnect=true&useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=CONVERT_TO_NULL&useSSL=false&serverTimezone=GMT%2B8

username: root

password: 123456

# 连接池配置

druid:

# 初始化大小,最小,最大

initial-size: 5

min-idle: 5

max-active: 20

# 配置获取连接等待超时的时间

max-wait: 60000

# 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位毫秒

time-between-eviction-runs-millis: 60000

# 配置一个连接在池中最小生存时间

min-evictable-idle-time-millis: 300000

validation-query: SELECT 1 FROM sys_user

test-while-idle: true

test-on-borrow: false

test-on-return: false

# 打开 PSCache,并且指定每个连接上 PSCache 的大小

pool-prepared-statements: true

max-pool-prepared-statement-per-connection-size: 20

# 配置监控统计拦截的 Filter,去掉后监控界面 SQL 无法统计,wall 用于防火墙

filters: stat,wall,log4j

# 通过 connection-properties 属性打开 mergeSql 功能;慢 SQL 记录

connection-properties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

# 配置 DruidStatFilter

web-stat-filter:

enabled: true

url-pattern: /*

exclusions: .js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*

# 配置 DruidStatViewServlet

stat-view-servlet:

url-pattern: /druid/*

# IP 白名单,没有配置或者为空,则允许所有访问

allow: 127.0.0.1

# IP 黑名单,若白名单也存在,则优先使用

deny: 192.168.31.253

# 禁用 HTML 中 Reset All 按钮

reset-enable: false

# 登录用户名/密码

login-username: root

login-password: 123

 

(3)启动 SpringBoot 项目访问地址 http://localhost:8080/druid/login.html 进行登录,若出现一下界面则配置成功

 

2. Java 代码配置 Bean

(1)pom.xml 依赖

<dependency>

<groupId>com.alibaba</groupId>

<artifactId>druid</artifactId>

<version>1.1.10</version>

</dependency>

(2)在配置文件 application.yml 中添加 Druid 配置

 

spring:

datasource:

type: com.alibaba.druid.pool.DruidDataSource

# 数据源的其他配置

initialSize: 5

minIdle: 5

maxActive: 20

maxWait: 60000

timeBetweenEvictionRunsMillis: 60000

minEvictableIdleTimeMillis: 300000

validationQuery: SELECT 1 FROM DUAL

testWhileIdle: true

testOnBorrow: false

testOnReturn: false

poolPreparedStatements: true

# 配置监控统计拦截的 filters,去掉后监控界面 sql 无法统计,"wall"用于防火墙

filters: stat,wall,log4j

maxPoolPreparedStatementPerConnectionSize: 20

useGlobalDataSourceStat: true

connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

 

(3)添加 DruidConfig.java 配置文件

 

import javax.servlet.Filter;

import javax.servlet.Servlet;

import javax.sql.DataSource;

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 com.alibaba.druid.pool.DruidDataSource;

import com.alibaba.druid.support.http.StatViewServlet;

import com.alibaba.druid.support.http.WebStatFilter;

@Configuration

publicclass DruidConfig {

@Bean

// 将所有前缀为spring.datasource下的配置项都加载DataSource中

@ConfigurationProperties(prefix = "spring.datasource")

public DataSource druidDataSource() {

returnnew DruidDataSource();

}

@Bean

public ServletRegistrationBean<Servlet> druidServlet() {

// 进行 druid 监控的配置处理

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

// 白名单

srb.addInitParameter("allow", "127.0.0.1");

// 黑名单

srb.addInitParameter("deny", "192.168.31.253");

// 用户名

srb.addInitParameter("loginUsername", "root");

// 密码

srb.addInitParameter("loginPassword", "root");

// 是否可以重置数据源

srb.addInitParameter("resetEnable", "false");

return srb;

}

@Bean

public FilterRegistrationBean<Filter> filterRegistrationBean() {

FilterRegistrationBean<Filter> frb = new FilterRegistrationBean<>();

frb.setFilter(new WebStatFilter());

// 所有请求进行监控处理

frb.addUrlPatterns("/*");

// 排除名单

frb.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.css,/druid/*");

return frb;

}

}

 

(4)启动 SpringBoot 项目访问地址 http://localhost:8080/druid/login.html 进行查看登录

 

3. 注解

(1)pom.xml 文件中添加 Druid 依赖(同方式二)

(2)配置文件添加信息(同方式二)

(3)配置 WebServlet

 

import javax.servlet.annotation.WebInitParam;

import javax.servlet.annotation.WebServlet;

import com.alibaba.druid.support.http.StatViewServlet;

@WebServlet(urlPatterns = "/druid/*",

initParams={

@WebInitParam(name="allow",value="192.168.16.110,127.0.0.1"),// IP白名单 (没有配置或者为空,则允许所有访问)

@WebInitParam(name="deny",value="192.168.16.111"),// IP黑名单 (存在共同时,deny优先于allow)

@WebInitParam(name="loginUsername",value="admin"),// 用户名

@WebInitParam(name="loginPassword",value="admin"),// 密码

@WebInitParam(name="resetEnable",value="false")// 禁用HTML页面上的“Reset All”功能

})

publicclass DruidServlet extends StatViewServlet {

privatestaticfinallong serialVersionUID = 1L;

}

 

(4)配置 WebFilter

import javax.servlet.annotation.WebFilter;

import javax.servlet.annotation.WebInitParam;

import com.alibaba.druid.support.http.WebStatFilter;

@WebFilter(filterName="druidWebStatFilter",urlPatterns="/*",

initParams={

@WebInitParam(name="exclusions",value="*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*")// 忽略资源

})

publicclass DruidFilter extends WebStatFilter {

}

 

(5)配置启动文件 SpringBootApplication 用于扫描我们配置的类

  添加 @ServletComponentScan 注解进行扫描

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.web.servlet.ServletComponentScan;

@SpringBootApplication

@ServletComponentScan("com.uy.servlet")

publicclass SpringBootApplication{

publicstaticvoid main(String[] args) {

SpringApplication.run(SpringBootApplication.class, args); } }

 

(6)启动 SpringBoot 项目访问地址 http://localhost:8080/druid/login.html 进行查看登录
