2.项目结构
3.pom.xml文件
org.springframework.boot spring-boot-starter-jdbc mysql mysql-connector-java runtime com.alibaba druid 1.1.8 log4j log4j 1.2.17 org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-maven-plugin
4.application.yml配置文件
spring: datasource: username: root password: wangqing url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai driver-class-name: com.mysql.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource # 数据源其他配置 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 # 合并多个DruidDataSource的监控数据 #useGlobalDataSourceStat: true mybatis: # 指定全局配置文件位置 #config-location: classpath:mybatis/mybatis-config.xml # 指定sql映射文件位置 mapper-locations: classpath:mapper/*.xml #如src/main/resources下的mappers文件下的TUserMapper.xml # schema: # - classpath:sql/department.sql #根据department.sql 的sql语句创建表 # - classpath:sql/employee.sql
5.创建一个DruidConfig的配置类,实例化Druid Datasource
package com.qingfeng.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.util.Arrays; import java.util.HashMap; import java.util.Map; @Configuration public class DruidConfig { //指定加载appliction.yml文件里面的spring.datasource开头的 // DruidDataSource类里面的属性与appliction.yml文件里面的spring.datasource开头的对应映射 @ConfigurationProperties(prefix = "spring.datasource") @Bean public DataSource druid(){ return new DruidDataSource(); } //配置Druid的监控 //1、配置一个管理后台的Servlet @Bean public ServletRegistrationBean statViewServlet(){ ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*"); MapinitParams = 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",""); bean.setInitParameters(initParams); return bean; } //2、配置一个web监控的filter @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; } }
6.创建一个UserController类测试
package com.qingfeng.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.jdbc.core.JdbcTemplate; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.ResponseBody; import java.util.List; import java.util.Map; @Controller public class UserController { @Autowired JdbcTemplate jdbcTemplate; @ResponseBody @GetMapping("/query") public Mapmap(){ List
7.运行项目,通过浏览器访问 http://localhost:8080/query
8.我们DruidConfig类里配置的下面代码可以帮我们实现监控
//配置Druid的监控 //1、配置一个管理后台的Servlet @Bean public ServletRegistrationBean statViewServlet(){ ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*"); MapinitParams = 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",""); bean.setInitParameters(initParams); return bean; }
9.我们启动项目,打开网址:http://localhost:8080/druid/login.html 可以通过登录,查看druid数据源状态监控
我们上面设置的是用户名:admin 密码:123456
