這篇文章主要介紹了shardingjdbc之配置druid數(shù)據(jù)庫連接池過程,具有很好的參考價值,希望對大家有所幫助,如有錯誤或未考慮完全的地方,望不吝賜教

shardingjdbc配置druid數(shù)據(jù)庫連接池

1、yml配置

  shardingsphere:
    datasource:
      names: cfdb0, cfdb1, cfdb2
      cfdb0:
        type: com.alibaba.druid.pool.DruidDataSource
        initialSize: 5   #連接池初始化連接數(shù)
        minIdle: 3       #連接池最小連接數(shù)
        maxActive: 20   #連接池最大連接數(shù)
        driver-class-name: com.mysql.jdbc.Driver
        url: jdbc:mysql://XX.xx.xx.xxx:3306/cfdb_0?useUnicode=true&characterEncoding=UTF-8&useSSL=false
        username: xxx
        password: xxxx

2、監(jiān)控配置類

@Configuration
public class DruidConfiguration {
 
	/**
	 * 注冊一個StatViewServlet
	 * @return
	 */
    @Bean
    public ServletRegistrationBean DruidStatViewServle(){
 
       //org.springframework.boot.context.embedded.ServletRegistrationBean提供類的進行注冊.
       ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
 
       //添加初始化參數(shù)：initParams
 
       //白名單：
       servletRegistrationBean.addInitParameter("allow","127.0.0.1");
 
       //IP黑名單 (存在共同時，deny優(yōu)先于allow) : 如果滿足deny的話提示:Sorry, you are not permitted to view this page.
       servletRegistrationBean.addInitParameter("deny","192.168.0.114");
 
       //登錄查看信息的賬號密碼.
       servletRegistrationBean.addInitParameter("loginUsername","admin");
       servletRegistrationBean.addInitParameter("loginPassword","123456");
 
       //是否能夠重置數(shù)據(jù).
       servletRegistrationBean.addInitParameter("resetEnable","false");
       return servletRegistrationBean;
    }
 
    /**
     * 注冊一個：filterRegistrationBean
     * @return
     */
    @Bean
    public FilterRegistrationBean druidStatFilter(){
       FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
 
       //添加過濾規(guī)則.
       filterRegistrationBean.addUrlPatterns("/*");
 
       //添加不需要忽略的格式信息.
       filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
 
       return filterRegistrationBean;
    }
}

3、添加pom依賴

     <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.3</version>
        </dependency>
