SpringBoot整合Druid
Druid是个十分强大的后端管理工具，具体的功能和用途请问阿里爸爸
1. 在pom.xml中导入包
<!-- alibaba 的druid数据库连接池 -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid-spring-boot-starter</artifactId>
<version>1.1.18</version>
</dependency>
2. 配置Druid
package xxx.xxx.xxx.config;
import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.beans.factory.annotation.Value;
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.Collections;
import java.util.HashMap;
import java.util.Map;
/**
* 配置 Druid
*
* @author axiang
*/
@Configuration
public class DruidConfig {
/* 设置Druid配置的默认前缀为 spring.datasource */
@ConfigurationProperties(prefix = "spring.datasource")
@Bean
public DataSource druid() {
return new DruidDataSource();
}
/* 自定义配置Druid管理界面的访问账户名 */
@Value("${xxx.config.druid.name}")
private String name;
/* 自定义配置Druid管理界面的访问密码 */
@Value("${xxx.config.druid.pwd}")
private String pwd;
/**
* 配置Druid的监控
* 配置一个管理后台的servlet
*
* @return
*/
@Bean
public ServletRegistrationBean statViewServlet() {
ServletRegistrationBean<StatViewServlet> bean = new ServletRegistrationBean<>(new StatViewServlet(), "/druid/*");
Map<String, String> initParams = new HashMap<>(10);
//账号
initParams.put("loginUsername", name);
//密码
initParams.put("loginPassword", pwd);
//默认允许所有
initParams.put("allow", "");
//不允许的黑名单ip
initParams.put("deny", "");
bean.setInitParameters(initParams);
return bean;
}
/**
* 配置一个监控的filter
*
* @return
*/
@Bean
public FilterRegistrationBean webStatFilter() {
FilterRegistrationBean bean = new FilterRegistrationBean();
bean.setFilter(new WebStatFilter());
Map<String, String> initParams = new HashMap<>(10);
initParams.put("exclusions", "*.js,*.css,/druid/*");
bean.setInitParameters(initParams);
bean.setUrlPatterns(Collections.singletonList("/*"));
return bean;
}
}
3. 访问和测试
输入下面的IP，进入页面访问Druid内容
