1、pom檔案加入

<dependency>
   <groupId>com.alibaba</groupId>
   <artifactId>druid-spring-boot-starter</artifactId>
   <version>1.1.10</version>
</dependency>

2、新增Java類

package com.ps.uzkefu.common;

import com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceBuilder;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.AutoConfigureBefore;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.boot.autoconfigure.jdbc.DataSourceProperties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DatabaseDriver;
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;

@Configuration
@ConditionalOnClass(com.alibaba.druid.pool.DruidDataSource.class)
@ConditionalOnProperty(name = "spring.datasource.type", havingValue = "com.alibaba.druid.pool.DruidDataSource", matchIfMissing = true)
public class DruidDataSource {

    /**
     * @see
     
     * @return DruidDataSource
     */
    @Bean
    @ConfigurationProperties("spring.datasource.druid")
    public DataSource dataSourceOne(){
        return DruidDataSourceBuilder.create().build();
    }

}
 

3、配置druid

• JDBC 配置

spring.datasource.druid.url=jdbc:mysql://192.168.32.139:3306/uzkefu?useUnicode=true&characterEncoding=UTF-8
spring.datasource.druid.username=root
spring.datasource.druid.password=zsj381599113_QQ

• 連線池配置

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.druid.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.druid.initial-size=5
spring.datasource.druid.max-active=100
spring.datasource.druid.min-idle=5
spring.datasource.druid.max-wait=60000
spring.datasource.druid.pool-prepared-statements=true
spring.datasource.druid.max-pool-prepared-statement-per-connection-size=20
spring.datasource.druid.validation-query=SELECT 1 FROM DUAL
spring.datasource.druid.validation-query-timeout=60000
spring.datasource.druid.test-on-borrow=false
spring.datasource.druid.test-on-return=false
spring.datasource.druid.test-while-idle=true
spring.datasource.druid.time-between-eviction-runs-millis=60000
spring.datasource.druid.min-evictable-idle-time-millis=100000
        
 

• 監控配置

# WebStatFilter配置，說明請參考Druid Wiki，配置_配置WebStatFilter
spring.datasource.druid.web-stat-filter.enabled=true
spring.datasource.druid.web-stat-filter.url-pattern=/*
spring.datasource.druid.web-stat-filter.exclusions=*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*


# StatViewServlet配置，說明請參考Druid Wiki，配置_StatViewServlet配置
spring.datasource.druid.stat-view-servlet.enabled= true
spring.datasource.druid.stat-view-servlet.url-pattern= /druid/*
spring.datasource.druid.stat-view-servlet.reset-enable= false
spring.datasource.druid.stat-view-servlet.login-username= admin
spring.datasource.druid.stat-view-servlet.login-password= admin
spring.datasource.druid.stat-view-servlet.allow= 127.0.0.1
spring.datasource.druid.stat-view-servlet.deny= 192.168.32.139 #訪問黑名單
 

如何配置 Filter

# 配置StatFilter
spring.datasource.druid.filter.stat.db-type=mysql
spring.datasource.druid.filter.stat.log-slow-sql=true
spring.datasource.druid.filter.stat.slow-sql-millis=5000

# 配置WallFilter
spring.datasource.druid.filter.wall.enabled=true
spring.datasource.druid.filter.wall.db-type=mysql
spring.datasource.druid.filter.wall.config.delete-allow=false
spring.datasource.druid.filter.wall.config.drop-table-allow=false

  不使用以上配置的話可以再程式碼中配置，datasource的配置還是要保留，監控的配置可以去掉，在程式碼中配置

package com.ps.uzkefu.common;

import com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceBuilder;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.AutoConfigureBefore;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.boot.autoconfigure.jdbc.DataSourceProperties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DatabaseDriver;
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;

@Configuration
@ConditionalOnClass(com.alibaba.druid.pool.DruidDataSource.class)
@ConditionalOnProperty(name = "spring.datasource.type", havingValue = "com.alibaba.druid.pool.DruidDataSource", matchIfMissing = true)
public class DruidDataSourceConfig {



    @Bean
    @ConfigurationProperties("spring.datasource.druid")
    public DataSource dataSourceOne(){
        return DruidDataSourceBuilder.create().build();
    }

    /**
     * 註冊一個StatViewServlet
     * @return
     */
    @Bean
    public ServletRegistrationBean druidStatViewServlet(){
        //org.springframework.boot.context.embedded.ServletRegistrationBean提供類的進行註冊.
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
        //新增初始化引數：initParams
        //白名單：
        servletRegistrationBean.addInitParameter("allow","127.0.0.1");
        //IP黑名單 (存在共同時，deny優先於allow) : 如果滿足deny的話提示:Sorry, you are not permitted to view this page.
        servletRegistrationBean.addInitParameter("deny","192.168.1.73");
        //登入檢視資訊的賬號密碼.
        servletRegistrationBean.addInitParameter("loginUsername","admin");
        servletRegistrationBean.addInitParameter("loginPassword","123456");
        //是否能夠重置資料.
        servletRegistrationBean.addInitParameter("resetEnable","false");
        return servletRegistrationBean;
    }

    /**
     * 註冊一個：filterRegistrationBean
     * @return
     */
    @Bean
    public FilterRegistrationBean druidStatFilter(){
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
        //新增過濾規則.
        filterRegistrationBean.addUrlPatterns("/*");
        //新增不需要忽略的格式資訊.
        filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
        return filterRegistrationBean;
    }


}
