1.引入druid

以上需要注意的时druid的版本问题，我之前引入了最新的druid相关依赖，此时启动程序后，控制台不报错，但是当访问druid时，页面404，后来查证，是因为版本不兼容问题。所以更换了1.1.10版本。
也有说自1.1.10以后。是否启用StatViewServlet默认值false，是不开启监控页面展示的。 所以你需要配置文件增加配置：spring.datasource.druid.stat-view-servlet.enabled=true就展示了，这种方法，我尝试了几次都没有成功，所以我最终还是选择了1.1.10版本的。
2.application.yml内容如下：
spring:
datasource:
username: root
password: root
url: jdbc:mysql://192.168.0.115:3306/jdbc
type: com.alibaba.druid.pool.DruidDataSource
# druid 数据源其他配置 当添加了如下配置，我们需要在程序中增加configuration配置来将这些配置映射到系统默认配置参数上去。
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
driver-class-name: com.mysql.cj.jdbc.Driver
# 自动加载数据库
# schema:
# - classpath:camera.sql
# initialization-mode: always
3.log4.properties配置文件
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
4.DruidConfig.java
package com.seegot.springboot.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.lang.reflect.Array; import java.util.Arrays; import java.util.HashMap; import java.util.Map; /** * @program: spring-boot-06-data-jdbc * @description: * @author: PP Zhang * @create: 2020-04-20 16:09 */ @Configuration public class DruidConfig {
// @Bean @ConfigurationProperties(prefix = "spring.datasource") public DataSource druid(){ return new DruidDataSource(); } // 配置druid的监控 // 1.配置管理后台的servlet public ServletRegistrationBean statViewServlet(){ ServletRegistrationBean<StatViewServlet> registrationBean = new ServletRegistrationBean<>(new StatViewServlet(), "/druid/*"); Map<String,String> initParams = new HashMap<>(); initParams.put("loginUsername","admin"); initParams.put("loginPassword","123456"); initParams.put("allow","localhost"); // 默认是允许所有的访问 initParams.put("deny","192.168.1.106"); // 拒绝谁访问 registrationBean.setInitParameters(initParams); return registrationBean; } // 2.配置监控的filter @Bean public FilterRegistrationBean webStatFilter(){ FilterRegistrationBean bean = new FilterRegistrationBean(); bean.setFilter(new WebStatFilter()); Map<String,String> initParams = new HashMap<>(); initParams.put("exclusions","*.js,*.css,/druid/*"); bean.setInitParameters(initParams); bean.setUrlPatterns(Arrays.asList("/*")); return bean; } }
