SpringBoot配置Druid

Druid是Java语言中最好的数据库连接池。Druid能够提供强大的监控和扩展功能。关于详细介绍可查看http://www.iteye.com/magazines/90

SpringBoot中集成Druid非常简单

一：yml中添加配置链接

spring:
  #MySQL数据库
  datasource:
    url: jdbc:mysql://182.254.221.58:3306/test?useSSL=false&&characterEncoding=utf8
    username: root
    password: Zoulu19900206@
    driver-class-name: com.mysql.jdbc.Driver
    #配置监控统计拦截的filters，去掉后监控界面sql将无法统计，wall用于防火墙
    filters: stat,wall,log4j
    #最大活跃数
    maxActive: 20
    #初始化数量
    initialSize: 1
    #最大连接等待超时时间
    maxWait: 60000
    #打开PSCache，并且指定每个连接PSCache的大小
    poolPreparedStatements: true
    maxPoolPreparedStatementPerConnectionSize: 20
    #通过connectionProperties属性打开mergeSql功能；慢sql记录
    connectionProperties: druid.stat.mergeSql=true;druif.stat.slowSqlMillis=5000
    minldle: 1
    timeBetweenEvictionRunsMillis: 60000
    minEvictableTimeMillis: 300000
    validationQuery: select 1 from dual
    testWhileldle: true
    testOnBorrow: false
    testOnReturn: false

  #JPA
  jpa:
    properties:
      hibernate:
        hbm2ddl.auto: true
        dialect: org.hibernate.dialect.MySQL5InnoDBDialect
    show-sql: true

二：添加DruidConfiguration配置类

@Configuration
public class DruidConfiguration {
    @Bean
    public ServletRegistrationBean statViewServlet(){
        //创建servlet注册实体
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
        //设置ip白名单
        servletRegistrationBean.addInitParameter("allow","127.0.0.1");
        //设置ip黑名单，如果allow与deny共同存在时,deny优先于allow
        servletRegistrationBean.addInitParameter("deny","192.168.0.19");
        //设置控制台管理用户
        servletRegistrationBean.addInitParameter("loginUsername","xiaopotian");
        servletRegistrationBean.addInitParameter("loginPassword","123456");
        //是否可以重置数据
        servletRegistrationBean.addInitParameter("resetEnable","false");
        return servletRegistrationBean;
    }

    @Bean
    public FilterRegistrationBean statFilter(){
        //创建过滤器
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
        //设置过滤器过滤路径
        filterRegistrationBean.addUrlPatterns("/*");
        //忽略过滤的形式
        filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
        return filterRegistrationBean;
    }

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource druidDataSource(){
        return new DruidDataSource();
    }
}

三：运行http://localhost:8080/druid进入登陆界面，用上面配置的用户名密码登录即可

非常的简单
