Springboot集成Druid方案:一个是在POM中直接配置druid-spring-boot-starter,不用写任何代码;一个是配置druid,写几行代码,可以加入;在方案一基础上加入stat、wall后进行验证登录。
测试环境是:SpringBoot2.1.4.RELEASE。
一、直接使用druid-spring-boot-starter
1、POM配置
<dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.10</version> </dependency> <!--自启动Druid管理后台--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.10</version> </dependency>
2、application.properties配置
### db config ### spring.datasource.type=com.alibaba.druid.pool.DruidDataSource spring.datasource.driverClassName=org.postgresql.Driver spring.datasource.url=jdbc:postgresql://localhost:5432/XXX?useUnicode=true&characterEncoding=utf8¤tSchema=public spring.datasource.username=postgres spring.datasource.password=XXX spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect spring.jpa.properties.hibernate.hbm2ddl.auto=update #config druid #连接池的设置 #初始化时建立物理连接的个数 spring.datasource.druid.initial-size=5 #最小连接池数量 spring.datasource.druid.min-idle=5 #最大连接池数量 maxIdle已经不再使用 spring.datasource.druid.max-active=20 #获取连接时最大等待时间,单位毫秒 spring.datasource.druid.max-wait=60000 #申请连接的时候检测,如果空闲时间大于timeBetweenEvictionRunsMillis,执行validationQuery检测连接是否有效。 spring.datasource.druid.test-while-idle=true #既作为检测的间隔时间又作为testWhileIdel执行的依据 spring.datasource.druid.time-between-eviction-runs-millis=60000 #销毁线程时检测当前连接的最后活动时间和当前时间差大于该值时,关闭当前连接 spring.datasource.druid.min-evictable-idle-time-millis=30000 #用来检测连接是否有效的sql 必须是一个查询语句 #mysql中为 select 'x' #oracle中为 select 1 from dual spring.datasource.druid.validation-query=select 'x' #申请连接时会执行validationQuery检测连接是否有效,开启会降低性能,默认为true spring.datasource.druid.test-on-borrow=false #归还连接时会执行validationQuery检测连接是否有效,开启会降低性能,默认为true spring.datasource.druid.test-on-return=false #当数据库抛出不可恢复的异常时,抛弃该连接 spring.datasource.druid.exception-sorter=true #是否缓存preparedStatement,mysql5.5+建议开启 #spring.datasource.druid.pool-prepared-statements=true #当值大于0时poolPreparedStatements会自动修改为true spring.datasource.druid.max-pool-prepared-statement-per-connection-size=20 #配置扩展插件 spring.datasource.druid.filters=stat,wall #通过connectProperties属性来打开mergeSql功能;慢SQL记录 spring.datasource.druid.connection-properties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500 #合并多个DruidDataSource的监控数据 spring.datasource.druid.use-global-data-source-stat=true #设置访问druid监控页的账号和密码,默认没有 #spring.datasource.druid.stat-view-servlet.login-username=admin #spring.datasource.druid.stat-view-servlet.login-password=admin ### mybatis config ### mybatis.config-locations=classpath:mybatis/mybatis-config.xml mybatis.mapper-locations=classpath:mybatis/mapper/*.xml mybatis.type-aliases-package=com.jrsc.supervisor.model ### log config ### logging.config=classpath:logback-spring.xml
3、输入http://localhost:9091/druid/webapp.html后,即可看到Druid监控面板
PS:广告无处不在
二、使用代码,可验证登录的方案
1、POM配置,删除:druid-spring-boot-starter
<dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.10</version> </dependency> <!--自启动Druid管理后台--> <!-- <dependency>--> <!-- <groupId>com.alibaba</groupId>--> <!-- <artifactId>druid-spring-boot-starter</artifactId>--> <!-- <version>1.1.10</version>--> <!-- </dependency>-->
2、application.properties配置不变
3、新建一个类:DruidConfig,注意包的引入,特别是:
package com.jrsc.supervisor.druid;
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;
3、DruidConfig具体实现如下:
@Configuration public class DruidConfig { @Bean @ConfigurationProperties(prefix = "spring.datasource") public DataSource getDataSource() { return new DruidDataSource(); } @Bean public ServletRegistrationBean druidStatViewServlet() { //ServletRegistrationBean提供类的进行注册 ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*"); //添加初始化参数:initParams //白名单: servletRegistrationBean.addInitParameter("allow", "127.0.0.1"); //IP黑名单(同时存在时,deny优先于allow) //如果满足deny,就提示:sorry,you are not permitted to view this page servletRegistrationBean.addInitParameter("deny", "192.168.1.73"); //登录查看信息的账号和密码 servletRegistrationBean.addInitParameter("loginUsername", "admin"); servletRegistrationBean.addInitParameter("loginPassword", "123456"); servletRegistrationBean.addInitParameter("resetEnable", "false"); return servletRegistrationBean; } @Bean public FilterRegistrationBean druidStatFilter() { FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter()); //添加过滤规则 filterRegistrationBean.addUrlPatterns("/*"); //添加需要忽略的格式信息 filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif," + "*.jpg,*.png, *.css,*.ico,/druid/*"); return filterRegistrationBean; }
4、对于SpringBoot的启动类,加入注解:@ServletComponentScan
5、输入:http://localhost:9091/druid/sql.html,观察Druid监控面板
三、通过在方案一基础上加入如下代码,实现验证登录
#设置访问druid监控页的账号和密码,默认没有 ## Druid WebStatFilter配置,说明请参考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=*.gif,*.png,*.jpg,*.html,*.js,*.css,*.ico,/druid/* # Druid StatViewServlet配置,说明请参考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=true spring.datasource.druid.stat-view-servlet.login-username=admin spring.datasource.druid.stat-view-servlet.login-password=123456 spring.datasource.druid.stat-view-servlet.allow= spring.datasource.druid.stat-view-servlet.deny=
四、测试
