SpringBoot整合Druid（阿里巴巴）数据源

（1）、添加相关依赖

 1         <dependency>
 2             <groupId>org.springframework.boot</groupId>
 3             <artifactId>spring-boot-starter-jdbc</artifactId>
 4         </dependency>
 5 
 6         <dependency>
 7             <groupId>mysql</groupId>
 8             <artifactId>mysql-connector-java</artifactId>
 9             <version>8.0.14</version>
10         </dependency>
11 
12         <dependency>
13             <groupId>com.alibaba</groupId>
14             <artifactId>druid</artifactId>
15             <version>1.1.12</version>
16         </dependency>

（2）、配置配置文件

1 spring.datasource.username=root
2 spring.datasource.password=123456
3 spring.datasource.url=jdbc:mysql://localhost:3306/JdbcDemo?serverTimezone=UTC
4 spring.datasource.driver-class-name=com.mysql.jdbc.Driver
5 spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

（3）将配置文件自定义属性和自定义数据源绑定（我配置文件中没有自定义属性），配置Druid监控

 1 package cn.coreqi.config;
 2 
 3 import com.alibaba.druid.pool.DruidDataSource;
 4 import com.alibaba.druid.support.http.StatViewServlet;
 5 import com.alibaba.druid.support.http.WebStatFilter;
 6 import org.springframework.boot.context.properties.ConfigurationProperties;
 7 import org.springframework.boot.web.servlet.FilterRegistrationBean;
 8 import org.springframework.boot.web.servlet.ServletRegistrationBean;
 9 import org.springframework.context.annotation.Bean;
10 import org.springframework.context.annotation.Configuration;
11 
12 import javax.sql.DataSource;
13 import java.util.Arrays;
14 import java.util.HashMap;
15 import java.util.Map;
16 
17 @Configuration
18 public class DruidConfig {
19     @Bean
20     @ConfigurationProperties(prefix = "spring.datasource")
21     public DataSource druid(){
22         return new DruidDataSource();
23     }
24 
25     //配置Druid监控
26 
27     //配置Druid管理后台的Servlet
28     //还记得如何在SpringBoot中注册Servlet吗？
29     @Bean
30     public ServletRegistrationBean statViewServlet(){
31         ServletRegistrationBean registrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
32         Map<String,String> initParams = new HashMap<>();
33         initParams.put("loginUsername","admin");
34         initParams.put("loginPassword","admin");
35         registrationBean.setInitParameters(initParams);
36         return registrationBean;
37     }
38 
39     //配置Druid监控的Filter
40     //还记得如何在SpringBoot中注册Filter吗？
41     @Bean
42     public FilterRegistrationBean webStatFilter(){
43         FilterRegistrationBean registrationBean = new FilterRegistrationBean(new WebStatFilter());
44         Map<String,String> initParams = new HashMap<>();
45         initParams.put("exclusions","*.js,*.css,/druid/*");
46         registrationBean.setInitParameters(initParams);
47         registrationBean.setUrlPatterns(Arrays.asList("/*"));
48         return registrationBean;
49     }
50 }

（4）访问http://localhost:8080/druid
