Springboot 下 Druid 的使用

搭了一个Springboot + jpa + druid的架子，记录一下druid 的配置。
Mybatis 下类似。

1.引入依赖

 <dependency>
     <groupId>com.alibabagroupId>
     <artifactId>druidartifactId>
     <version>1.0.29version>
 dependency>

2.注解配置

@Configuration
public class DruidConfiguration {

    //使用连接池dataSource
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource() {
        DruidDataSource druidDataSource = new DruidDataSource();
        return druidDataSource;
    }


    @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", "192.168.0.1");
        // 设置控制台管理用户
        servletRegistrationBean.addInitParameter("loginUsername", "admin");
        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
    public JdkRegexpMethodPointcut druidStatPointcut() {
        JdkRegexpMethodPointcut druidStatPointcut = new JdkRegexpMethodPointcut();
        String patterns = "com.rock.geological.web.*.service.*";
        //可以set多个
        druidStatPointcut.setPatterns(patterns);
        return druidStatPointcut;
    }

    @Bean
    public Advisor druidStatAdvisor() {
        return new DefaultPointcutAdvisor(druidStatPointcut(), druidStatInterceptor());
    }

    @Bean
    public DruidStatInterceptor druidStatInterceptor() {
        return new DruidStatInterceptor();
    }


}

3.yml 配置文件

spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/geological
    username: root
    password: drq2028701
    driver-class-name: com.mysql.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    testOnReturn: false
    testOnBorrow: false
    testWhileIdle: true
    # 下面为连接池的补充设置，应用到上面所有数据源中
    # 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
    dbcp2:
       min-idle: 5
       initial-size: 5
       max-total: 5
       max-wait-millis: 200
    # 通过connectProperties属性来打开mergeSql功能；慢SQL记录
    #connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
