今天小編給大家分享一下SpringBoot怎么進行整合Druid數據源的相關知識點，內容詳細，邏輯清晰，相信大部分人都還太了解這方面的知識，所以分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后有所收獲，下面我們一起來了解一下吧。
使用自定義方式整合Druid
在pom.xml添加相關依賴
<!--數據庫相關--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jdbc</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.6</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.2.6</version> </dependency> </dependencies>
application.properties
server.port=8080
spring.datasource.url=jdbc:mysql://localhost:3306/db_springtest?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
配置Druid的監控頁功能：
Druid內置提供了一個StatViewServlet用于展示Druid的統計信息。官方文檔 - 配置StatViewServlet
這個StatViewServlet的用途包括：
提供監控信息展示的html頁面
提供監控信息的JSON API
Druid內置提供一個StatFilter，用于統計監控信息。官方文檔 - 配置_StatFilter
WebStatFilter用于采集web-jdbc關聯監控的數據，如SQL監控、URI監控。官方文檔 - 配置WebStatFilter
Druid提供了WallFilter，它是基于SQL語義分析來實現防御SQL注入攻擊的。官方文檔 - 配置 wallfilter
DataSourceConfig
package com.limi.springboottest2.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.sql.SQLException;
import java.util.Arrays;
@Configuration
public class DataSourceConfig {
@Bean
@ConfigurationProperties("spring.datasource")//復用配置文件的數據源配置, 這樣就不用寫代碼一個一個set了
public DataSource dataSource() throws SQLException {
DruidDataSource druidDataSource = new DruidDataSource();
//加入監控和防火墻功能功能
druidDataSource.setFilters("stat,wall");
return druidDataSource;
}
/**
* 配置 druid的監控頁功能
* @return
*/
@Bean
public ServletRegistrationBean statViewServlet(){
StatViewServlet statViewServlet = new StatViewServlet();
ServletRegistrationBean<StatViewServlet> registrationBean =
new ServletRegistrationBean<>(statViewServlet, "/druid/*");
//監控頁賬號密碼：
registrationBean.addInitParameter("loginUsername","admin");
registrationBean.addInitParameter("loginPassword","123456");
return registrationBean;
}
/**
* WebStatFilter 用于采集web-jdbc關聯監控的數據。
*/
@Bean
public FilterRegistrationBean webStatFilter(){
WebStatFilter webStatFilter = new WebStatFilter();
FilterRegistrationBean<WebStatFilter> filterRegistrationBean = new FilterRegistrationBean<>(webStatFilter);
filterRegistrationBean.setUrlPatterns(Arrays.asList("/*"));
filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
return filterRegistrationBean;
}
}HelloController
package com.limi.springboottest2.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;
@Controller
public class HelloController {
@Autowired
private JdbcTemplate jdbcTemplate;
@ResponseBody
@GetMapping("/sql")
public String test1(){
String sql = "select count(*) from t_user";
Long i = jdbcTemplate.queryForObject(sql, Long.class);
return i.toString();
}

使用場景啟動器整合druid, 效果和自定義方式一樣, 但更加方便
在pom.xml添加相關依賴
