Spring Boot项目配置Druid数据源(druid)

本章中使用的druid依赖是

<dependency>
　　<groupId>com.alibaba</groupId>
　　<artifactId>druid</artifactId>
　　<version>1.1.15</version>
</dependency>

不是

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.22</version>
</dependency

两种依赖的配置方式不同, 如果你使用的是druid-spring-boot-starter的依赖方式, 请看(Spring Boot项目配置Druid数据源(druid-spring-boot-starter))[https://www.cnblogs.com/no-celery/p/14381542.html]

yml文件配置

具体配置也可以参考(Spring Boot项目配置Druid数据源(druid-spring-boot-starter))[https://www.cnblogs.com/no-celery/p/14381542.html]

spring:
  datasource:
    username: root
    password: XXX
    url: jdbc:mysql://XXX.XX.XX.XXX:33306/数据库名?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=Asia/Shanghai
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    #   数据源其他配置
    initialSize: 5
    minIdle: 5
    maxActive: 20
    maxWait: 60000
    timeBetweenEvictionRunsMillis: 60000
    minEvictableIdleTimeMillis: 300000
    validationQuery: SELECT 'x'
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    poolPreparedStatements: true
    #   配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙
    filters: stat,wall,slf4j
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

Druid Config

druid依赖的方式还需要创建对应的config类

@Configuration
public class DruidConfig {
 
    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druid() {
        return new DruidDataSource();
    }
}

配置Durid的监控

/**
 * 数据库链接池druid监控平台的配置
 * 访问路径 http://localhost:8080/druid/index.html
 *
 */
@Configuration
@Slf4j
public class DruidConfiguration {

    @Bean
    public ServletRegistrationBean druidServlet() {
        logger.info("init Druid Servlet Configuration ");
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        // IP白名单
//        servletRegistrationBean.addInitParameter("allow", "*");
        // IP黑名单(共同存在时，deny优先于allow)
//        servletRegistrationBean.addInitParameter("deny", "127.0.0.1");
        //控制台管理用户
        servletRegistrationBean.addInitParameter("loginUsername", "admin");
        servletRegistrationBean.addInitParameter("loginPassword", "admin");
        //是否能够重置数据 禁用HTML页面上的“Reset All”功能
        servletRegistrationBean.addInitParameter("resetEnable", "false");
        return servletRegistrationBean;
    }
    @Bean
    public FilterRegistrationBean filterRegistrationBean() {
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
        filterRegistrationBean.addUrlPatterns("/*");
        filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
        return filterRegistrationBean;
    }
}
