springboot項(xiàng)目中如何實(shí)現(xiàn)訪問(wèn)druid內(nèi)置監(jiān)控頁(yè)面

發(fā)布時(shí)間:2021-06-21 10:47:09 來(lái)源:億速云 閱讀:1064 作者:小新 欄目:開(kāi)發(fā)技術(shù)

小編給大家分享一下springboot項(xiàng)目中如何實(shí)現(xiàn)訪問(wèn)druid內(nèi)置監(jiān)控頁(yè)面,相信大部分人都還不怎么了解,因此分享這篇文章給大家參考一下,希望大家閱讀完這篇文章后大有收獲,下面讓我們一起去了解一下吧!

springboot 訪問(wèn)druid內(nèi)置監(jiān)控頁(yè)面

1、首先加入druid依賴

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.9</version>
</dependency>

2、設(shè)置配置文件:

# 數(shù)據(jù)庫(kù)訪問(wèn)配置
# 主數(shù)據(jù)源,默認(rèn)的
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=123456
 
# 下面為連接池的補(bǔ)充設(shè)置,應(yīng)用到上面所有數(shù)據(jù)源中
# 初始化大小,最小,最大
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
# 配置獲取連接等待超時(shí)的時(shí)間
spring.datasource.maxWait=60000
# 配置間隔多久才進(jìn)行一次檢測(cè),檢測(cè)需要關(guān)閉的空閑連接,單位是毫秒
spring.datasource.timeBetweenEvictionRunsMillis=60000
# 配置一個(gè)連接在池中最小生存的時(shí)間,單位是毫秒
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
# 打開(kāi)PSCache,并且指定每個(gè)連接上PSCache的大小
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
# 配置監(jiān)控統(tǒng)計(jì)攔截的filters,去掉后監(jiān)控界面sql無(wú)法統(tǒng)計(jì),'wall'用于防火墻
spring.datasource.filters=stat,wall,log4j
# 通過(guò)connectProperties屬性來(lái)打開(kāi)mergeSql功能;慢SQL記錄
spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
# 合并多個(gè)DruidDataSource的監(jiān)控?cái)?shù)據(jù)
#spring.datasource.useGlobalDataSourceStat=true

3、啟動(dòng)項(xiàng)目后

訪問(wèn)頁(yè)面http://127.0.0.1:8001/druid/sql.html,就可以訪問(wèn)監(jiān)控頁(yè)面了,其中ip和端口號(hào)為項(xiàng)目的ip和端口號(hào)。

頁(yè)面效果如下:

4、設(shè)置druid訪問(wèn)頁(yè)面的用戶名和密碼

只需要在springboot啟動(dòng)類(lèi)中加入@bean配置即可:

@Bean
public ServletRegistrationBean<StatViewServlet> druidStatViewServlet() {
	ServletRegistrationBean<StatViewServlet> registrationBean = new ServletRegistrationBean<>(new StatViewServlet(),  "/druid/*");
	registrationBean.addInitParameter("allow", "127.0.0.1");// IP白名單 (沒(méi)有配置或者為空,則允許所有訪問(wèn))
	registrationBean.addInitParameter("deny", "");// IP黑名單 (存在共同時(shí),deny優(yōu)先于allow)
	registrationBean.addInitParameter("loginUsername", "root");
	registrationBean.addInitParameter("loginPassword", "1234");
	registrationBean.addInitParameter("resetEnable", "false");
	return registrationBean;
}

druid監(jiān)控頁(yè)面的配置和使用

Druid運(yùn)用背景

Druid是由阿里巴巴團(tuán)隊(duì)開(kāi)發(fā)的,能夠提供強(qiáng)大的監(jiān)控和擴(kuò)展功能的數(shù)據(jù)庫(kù)連接池。github地址

本項(xiàng)目的項(xiàng)目框架為SpringBoot+Mybatis+Security,并將druid到項(xiàng)目中,作為一個(gè)輔助工具幫助提升項(xiàng)目的性能。

Druid配置

1、設(shè)置項(xiàng)目依賴

<dependency>
 <groupId>com.alibaba</groupId>
     <artifactId>druid-spring-boot-starter</artifactId>
     <version>1.1.10</version>
 </dependency>

2、application.yml中配置Druid數(shù)據(jù)源,并設(shè)置監(jiān)控參數(shù)。YAML文件格式化校驗(yàn)(https://old.qqe2.com/jsontool/yaml.php)

spring:
    #####DruidDataSource配置#####################
    type: com.alibaba.druid.pool.DruidDataSource
    initialSize: 5
    minIdle: 5
    maxActive: 20
    # 配置獲取連接等待超時(shí)的時(shí)間
    maxWait: 60000
    # 配置間隔多久才進(jìn)行一次檢測(cè),檢測(cè)需要關(guān)閉的空閑連接,單位是毫秒
    timeBetweenEvictionRunsMillis: 60000
    # 配置一個(gè)連接在池中最小生存的時(shí)間,單位是毫秒
    minEvictableIdleTimeMillis: 300000
    validationQuery: SELECT 1 FROM DUAL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    # 打開(kāi)PSCache,并且指定每個(gè)連接上PSCache的大小
    poolPreparedStatements: true
    maxPoolPreparedStatementPerConnectionSize: 20
    # 配置監(jiān)控統(tǒng)計(jì)攔截的filters,去掉后監(jiān)控界面sql無(wú)法統(tǒng)計(jì),'wall'用于防火墻
    filters: stat,wall,slf4j
    # 通過(guò)connectProperties屬性來(lái)打開(kāi)mergeSql功能;慢SQL記錄
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
    #合并多個(gè)DruidDataSource的監(jiān)控?cái)?shù)據(jù)
    useGlobalDataSourceStat: true

3、設(shè)置druid訪問(wèn)頁(yè)面的用戶名和密碼,只需要在springboot啟動(dòng)類(lèi)中加入@bean配置即可:

  /**                                                                                                            
   * @description 注冊(cè)一個(gè)StatViewServlet,進(jìn)行druid監(jiān)控頁(yè)面配置                                                               
   * @return servlet registration bean                                                                           
   */                                                                                                            
  @Bean                                                                                                          
  public ServletRegistrationBean druidStatViewServlet() { 
     //先配置管理后臺(tái)的servLet,訪問(wèn)的入口為/druid/                                                       
      ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(                             
             new StatViewServlet(), "/druid/*");
      // IP白名單 (沒(méi)有配置或者為空,則允許所有訪問(wèn))
      servletRegistrationBean.addInitParameter("allow", "127.0.0.1");
      // IP黑名單 (存在共同時(shí),deny優(yōu)先于allow)                                                      
   servletRegistrationBean.addInitParameter("deny", "");           
      servletRegistrationBean.addInitParameter("loginUsername", "admin");                                        
      servletRegistrationBean.addInitParameter("loginPassword", "sdb3309");                                      
      servletRegistrationBean.addInitParameter("resetEnable", "false");                                          
      return servletRegistrationBean;                                                                            
  }

4、注冊(cè)一個(gè)過(guò)濾器,允許Druid監(jiān)控頁(yè)面的正常瀏覽

 /**                                                                                                                      
  * @description 注冊(cè)一個(gè)過(guò)濾器,允許頁(yè)面正常瀏覽                                                                   
  * @return filter registration bean                                                                                      
  */                                                                                                                      
 @Bean                                                                                                                    
 public FilterRegistrationBean druidStatFilter(){                                                                         
     FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(                                          
             new WebStatFilter());                                                                                        
     // 添加過(guò)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;                                                                                       
 }

5、啟動(dòng)項(xiàng)目后,訪問(wèn)頁(yè)面http://ip:port/druid/sql.html(其中ip和端口號(hào)為項(xiàng)目的ip和端口號(hào)),使用配置的用戶名與密碼登錄,就可以訪問(wèn)監(jiān)控頁(yè)面了。

Druid詳細(xì)配置

開(kāi)啟慢sql監(jiān)控

SQL監(jiān)控中,有一項(xiàng)關(guān)于sql執(zhí)行最慢執(zhí)行時(shí)間的統(tǒng)計(jì),但是只有一個(gè)值,就是一條sql語(yǔ)句最慢的執(zhí)行時(shí)間記錄,其他執(zhí)行時(shí)間是看不到的,只能通過(guò)總時(shí)間來(lái)進(jìn)行粗略的估計(jì);一旦項(xiàng)目重啟,這些記錄就全部消失,因此需要制定相應(yīng)的日志輸出策略。

具體步驟:

1、配置慢sql及日志攔截器

 /**                          
  * @description 配置慢sql攔截器        
  * @return                   
  */                          
  @Bean(name = "statFilter")                                                 
  public StatFilter statFilter(){                                            
      StatFilter statFilter = new StatFilter();                              
      //慢sql時(shí)間設(shè)置,即執(zhí)行時(shí)間大于200毫秒的都是慢sql                                         
      statFilter.setSlowSqlMillis(30);                                       
      statFilter.setLogSlowSql(true);
      statFilter.setMergeSql(true);                                        
      return statFilter;                                                     
  }                                                                          
   /**                          
  * @description 配置日志攔截器        
  * @return                   
  */                                                                         
  @Bean(name = "logFilter")                                                  
  public Slf4jLogFilter logFilter(){                                         
      Slf4jLogFilter slf4jLogFilter = new Slf4jLogFilter();                  
      slf4jLogFilter.setDataSourceLogEnabled(true);                          
      slf4jLogFilter.setStatementExecutableSqlLogEnable(true);               
      return slf4jLogFilter;                                                 
  }

2、修改application.yml,增加慢sql日志的輸出策略

  logging:
   pattern: #配置日志格式 %d:日期 , %msg:日志信息 ,%n換行
    console: "%d - %msg%n" #設(shè)置控制臺(tái)打印格式
   file: "%d{yyyy/MM/dd-HH:mm} %-5level %logger- %msg%n"
 level:
  root: INFO
     org:
       springframework:
       security: ERROR
       web: ERROR
       hhu.yu: INFO
 file:
  name: YU.log
     max-history: 30

3、修改數(shù)據(jù)源配置,設(shè)置慢sql攔截器和sql攔截器

@Bean                                                                    
 @Primary                      
 @Qualifier("mainDataSource")                                             
 @ConfigurationProperties(prefix = "spring.datasource.main")              
 DataSource mainConfig() throws SQLException{                             
     DruidDataSource build = DruidDataSourceBuilder.create().build();     
     List<Filter> filters = new ArrayList<>();                            
     filters.add(statFilter());                                           
     filters.add(logFilter());                                            
     build.setProxyFilters(filters);                                      
     return build;

重啟系統(tǒng)后查看druid監(jiān)控后臺(tái),由于設(shè)置了慢sql的時(shí)間為大于200毫秒,所以執(zhí)行時(shí)間大于200毫秒的都會(huì)被紅色標(biāo)注。查看日志文件,可以看到日志文件中存在慢sql記錄的數(shù)據(jù)(包括慢sql以及這條sql語(yǔ)句執(zhí)行的時(shí)間)

開(kāi)啟Spring監(jiān)控

在監(jiān)控面板中開(kāi)啟spring監(jiān)控功能

@Configuration
@EnableAspectJAutoProxy(proxyTargetClass = true)
public class DruidAspectConfig {
    @Bean
    public DruidStatInterceptor druidStatInterceptor() {
        DruidStatInterceptor dsInterceptor = new DruidStatInterceptor();
        return dsInterceptor;
    }
    @Bean
    @Scope("prototype")
    public JdkRegexpMethodPointcut druidStatPointcut() {
        JdkRegexpMethodPointcut pointcut = new JdkRegexpMethodPointcut();
        pointcut.setPatterns("com.qa.cloud.mapper.*","com.qa.cloud.service.*");
        return pointcut;
    }
    @Bean
    public DefaultPointcutAdvisor druidStatAdvisor(DruidStatInterceptor druidStatInterceptor, JdkRegexpMethodPointcut druidStatPointcut) {
        DefaultPointcutAdvisor defaultPointAdvisor = new DefaultPointcutAdvisor();
        defaultPointAdvisor.setPointcut(druidStatPointcut);
        defaultPointAdvisor.setAdvice(druidStatInterceptor);
        return defaultPointAdvisor;
    }
