Spring Boot配置druid监控页功能

1.导入坐标

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.4.1</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.hao</groupId><artifactId>spring-boot-jdbc</artifactId><version>0.0.1-SNAPSHOT</version><name>spring-boot-jdbc</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version><mysql.version>8.0.19</mysql.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-jdbc</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.1.2</version></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

2.在application.ymal中配置数据源

spring:datasource:url: jdbc:mysql://localhost:3306/jdbc?serverTimezone=UTCusername: rootdriver-class-name: com.mysql.cj.jdbc.Driverpassword: hao20001010

3.编写配置类

@Configuration
public class MyDataSourceConfig {@ConfigurationProperties("spring.datasource")//与配置文件进行绑定@Beanpublic DruidDataSource druidDataSource(){return new DruidDataSource();}
//配置监控页功能@Beanpublic ServletRegistrationBean statsViewServlet(){StatViewServlet statViewServlet = new StatViewServlet();ServletRegistrationBean<StatViewServlet> bean = new ServletRegistrationBean<>(statViewServlet, "/druid/*");return bean;}
}

Spring中内置的有数据库连接池，如果使用Druid连接池，需要将该组件导入到容器中

4.运行访问http://localhost:8080/druid

结果：

接着通过查询数据库查看SQL监控

编写Controller类

/*** @author:抱着鱼睡觉的喵喵* @date:2020/12/23* @description:*/
@RestController
public class SqlController {@AutowiredJdbcTemplate jdbcTemplate;@GetMapping("/sql")public String control(){Long query= jdbcTemplate.queryForObject("select count(*) from admin", Long.class);return "query";}
}

*更改配置类，开启监控功能

@Configuration
public class MyDataSourceConfig {@ConfigurationProperties("spring.datasource")@Beanpublic DruidDataSource druidDataSource() throws SQLException {DruidDataSource dataSource = new DruidDataSource();//加入监控功能dataSource.setFilters("stat");return dataSource;}@Beanpublic ServletRegistrationBean statsViewServlet(){StatViewServlet statViewServlet = new StatViewServlet();ServletRegistrationBean<StatViewServlet> bean = new ServletRegistrationBean<>(statViewServlet, "/druid/*");return bean;}
}

1.访问http://localhost:8080/druid，点开SQL监控
2.打开另外一个页面访问http://localhost:8080/sql
3.刷新监控页出现如下

开启Web应用监控

在配置类中导入开启Web应用的组件

/*** @author:抱着鱼睡觉的喵喵* @date:2020/12/23* @description:*/@Configuration
public class MyDataSourceConfig {@ConfigurationProperties("spring.datasource")@Beanpublic DruidDataSource druidDataSource() throws SQLException {DruidDataSource dataSource = new DruidDataSource();//加入监控功能dataSource.setFilters("stat");return dataSource;}@Beanpublic ServletRegistrationBean statsViewServlet(){StatViewServlet statViewServlet = new StatViewServlet();ServletRegistrationBean<StatViewServlet> bean = new ServletRegistrationBean<>(statViewServlet, "/druid/*");return bean;}/*** WebStatFilter 用于采集web-jdbc关联监控的数据* @return*/@Beanpublic FilterRegistrationBean webStatFilter(){WebStatFilter webStatFilter = new WebStatFilter();FilterRegistrationBean<WebStatFilter> filterFilter=new FilterRegistrationBean<>(webStatFilter);filterFilter.setUrlPatterns(Arrays.asList("/*"));//拦截所有资源//以下资源不拦截*.js,*.gif,*.jpg,*.css等filterFilter.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.css,*.ico,/druid/*");return filterFilter;}
}

2.运行测试
访问http://localhost:8080/sql

查看Web应用监控数据

开启防火墙

在filter中添加wall

启动访问http://localhost:8080/druid，点击SQL防火墙

访问http://localhost:8080/sql

再次刷新监控页面

开启druid登录功能

在配置类中增加
运行访问http://localhost:8080/druid

可以在配置文件进行配置

============================================================================================================================================================================================================================================
下面使用ymal配置文件进行配置
导入坐标

         <dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>1.2.4</version></dependency>

spring:datasource:url: jdbc:mysql://localhost:3306/jdbc?serverTimezone=UTCusername: rootdriver-class-name: com.mysql.cj.jdbc.Driverpassword: hao20001010druid:filters: stat,wallaop-patterns: com.hao.boot.*stat-view-servlet:enabled: truelogin-username: adminlogin-password: adminreset-enable: falseweb-stat-filter:enabled: trueurl-pattern: /*exclusions: '*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*'filter:stat:slow-sql-millis: 1000log-slow-sql: trueenabled: truewall:enabled: true
