SpringBoot整合Druid

首先介绍一下Druid

整合过程！

1、首先引入maven依赖

        
        
            com.alibaba
            druid
            1.1.8
        

2、在yml或者properties中配置druid属性（此处给出了全部的属性配置）

spring:
  datasource:
    username: root
    password: ****
    url: jdbc:mysql://192.111.111.111/JDBC
    driver-class-name: com.mysql.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 1 FROM DUAL
    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,log4j
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

3、编写config文件

@Configuration
public class DruidConfig {

    // 配置yml属性
    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druid(){
        return new DruidDataSource();
    }

    // 配置监控
    // 1、配置一个管理后台的servlet
    @Bean
    public ServletRegistrationBean statViewServlet(){
        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
        Map initParams = new HashMap<>();
        initParams.put("loginUsername","admin");
        initParams.put("loginPassword","111111");
        initParams.put("allow","localhost");// 默认允许所有
//        initParams.put("deny","111111");
        bean.setInitParameters(initParams);

        return bean;
    }
    // 2、配置一个filter
    @Bean
    public FilterRegistrationBean webStatFilter(){
        FilterRegistrationBean bean = new FilterRegistrationBean();
        bean.setFilter(new WebStatFilter());
        Map initParams = new HashMap<>();
        initParams.put("exclusions","*.js,*.css,/druid/*");
//        initParams.put("loginPassword","111111");
//        initParams.put("allow","localhost");// 默认允许所有
        bean.setInitParameters(initParams);
        bean.setUrlPatterns(Arrays.asList("/*"));
        return bean;

    }


}

配置完成。

这个时候再浏览器中输入  localhost:8080/druid/  便可以访问druid管理界面了

工具十分强大。感谢阿里爸爸
