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

http://[IP地址]:[端口号]/[项目部署名]/druid/index.html
