SpringBoot配置Druib

1、导入依赖

 1         
 2         
 3             com.alibaba
 4             druid
 5             1.1.21
 6         
 7 
 8         
 9             org.springframework.boot
10             spring-boot-starter-jdbc
11         
12 
13         
14         
15             log4j
16             log4j
17             1.2.17
18         
19         
20         
21             mysql
22             mysql-connector-java
23             runtime
24         

2、配置数据源

 1 spring:
 2   datasource:
 3     username: xxxx
 4     password: xxxx
 5     url: jdbc:mysql://xxxx:3306/yidai?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true
 6     driver-class-name: com.mysql.cj.jdbc.Driver
 7     type: com.alibaba.druid.pool.DruidDataSource
 8 
 9     initialSize: 5
10     minIdle: 5
11     maxActive: 20
12     maxWait: 60000
13     timeBetweenEvictionRunsMillis: 60000
14     minEvictableIdleTimeMillis: 300000
15     validationQuery: SELECT 1 FROM DUAL
16     testWhileIdle: true
17     testOnBorrow: false
18     testOnReturn: false
19     poolPreparedStatements: true
20     #   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
21     filters: stat,wall,log4j
22     maxPoolPreparedStatementPerConnectionSize: 20
23     useGlobalDataSourceStat: true
24     connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

3、DruibConifg配置类

package com.example.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.servlet.ServletRegistration;
import javax.sql.DataSource;
import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;

/**

 */


@Configuration
public class DruidConfig {

    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druib(){
        return new DruidDataSource();
    }

    @Bean
    public ServletRegistrationBean statViewServlet() {
        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        Map initParams = new HashMap<>();

        initParams.put("loginUsername", "admin");
        initParams.put("loginPassword", "123456");
        initParams.put("allow", "");// 默认就是允许所有访问
        initParams.put("deny", "10.18.172.124");

        bean.setInitParameters(initParams);
        return bean;
    }


    @Bean
    public FilterRegistrationBean webStatFilter() {
        FilterRegistrationBean bean = new FilterRegistrationBean();
        bean.setFilter(new WebStatFilter());

        Map initParams = new HashMap<>();
        initParams.put("exclusions", "*.js,*.css,/druid/*");

        bean.setInitParameters(initParams);

        bean.setUrlPatterns(Arrays.asList("/*"));

        return bean;
    }


}

4、页面访问

　http://localhost:8080/druid/
