爬虫学习记录<1>-----Quartz

Quartz是什么

Quartz是一个强大的任务调度框架
简而言之就是:在某一个特定的时间点干某件事,并且时间的触发条件可以非常复杂,复杂到需要一个专门的框架来干这个事。 Quartz就是这样一个框架,你给它定义一个触发条件,它负责在特定时间点触发相应的Job。

一个Quartz工程

1.建立一个maven项目

参考:Maven(一)如何用Eclipse创建一个Maven项目

2.引入quartz的依赖

使用Quartz,仅需要在maven的pom文件中添加依赖即可。我使用的是版本2.3.0,大家可以在maven的仓库获取到最新的版本依赖,地址:http://mvnrepository.com/artifact/org.quartz-scheduler/quartz

<!-- https://mvnrepository.com/artifact/org.quartz-scheduler/quartz -->
<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>2.3.0</version>
</dependency>
3.简单实例

参考:Quartz的基本使用之入门(2.3.0版本)
示例中使用了两种Trigger:SimpleTrigger/CronTrigger。简单的定时任务,可以采用SimpleTrigger,复杂的任务一般采用CronTrigger.cronTrigger。后者不仅可以设定简单的触发时间表,更可以设定非常复杂的触发时间表。

4.cron表达式编写规则

简单的使用可以用在线生成:http://cron.qqe2.com/
注:cron表达式中不区分大小写

  • Quartz Cron 表达式支持7个域,分别是秒/分/时/日/月/周/年。其中年是非必须项。
名称是否必须允许值特殊字符
0-59, - * /
0-59, - * /
0-23, - * /
1-31, - * ? / L W C
1-12 或 JAN-DEC, - * /
1-7 或 SUN-SAT, - * ? / L C #
空 或 1970-2099, - * /

星号(*):可用在所有字段中,表示对应时间域的每一个时刻。例如,在分钟字段时,表示“每分钟”;

问号(?):该字符只在日期和星期字段中使用,它通常指定为“无意义的值”,相当于点位符;

减号(-):表达一个范围,如在小时字段中使用“10-12”,则表示从10到12点,即10,11,12;

逗号(,):表达一个列表值,如在星期字段中使用“MON,WED,FRI”,则表示星期一、星期三和星期五;

斜杠(/):x/y表达一个等步长序列,x为起始值,y为增量步长值。如在分钟字段中使用0/15,则表示为0,15,30和45秒,而5/15在分钟字段中表示5,20,35,50。也可以使用*/y,等同于0/y;

L:该字符只在日期和星期字段中使用,代表“Last”的意思,但它在两个字段中意思不同。L在日期字段中,表示这个月份的最后一天,如一月的31号,非闰年二月的28号;如果L用在星期中,则表示星期六,等同于7。但是,如果L出现在星期字段里,而且在前面有一个数值X,则表示“这个月最后的星期x”。例如,6L表示该月最后的星期五;

W:该字符只能出现在日期字段里,是对前导日期的修饰,表示离该日期最近的工作日。例如15W表示离该月15号最近的工作日,如果该月15号是星期六,则匹配14号星期五;如果15日是星期日,则匹配16号星期一;如果15号是星期二,那结果就是15号星期二。但必须注意关联的匹配日期不能够跨月,如你指定1W,如果1号是星期六,结果匹配的是3号星期一,而非上个月最后的那天。W字符串只能指定单一日期,而不能指定日期范围;

LW组合:在日期字段可以组合使用LW,它的意思是当月的最后一个工作日;

井号(#):该字符只能在星期字段中使用,表示当月某日。如6#3表示当月的第三个星期五(6表示星期五,#3表示当前的第三个),而4#5表示当月的第五个星期三,假设当月没有第五个星期三,忽略不触发;

C:该字符只在日期和星期字段中使用,代表“Calendar”的意思。它的意思是计划所关联的日期,如果日期没有被关联,则相当于日历中所有日期。例如5C在日期字段中就相当于日历5日以后的第一天。1C在星期字段中相当于星期日后的第一天。

Cron表达式对特殊字符的大小写不敏感,对代表星期的缩写英文大小写也不敏感。

如下是一些官方案例

<think>我们有两个修改点:1.在<build>的<plugins>中,将maven-compiler-plugin添加版本号3.11.02.在<repositories>中,添加Maven中央仓库(central)并调整阿里云仓库(aliyun)的配置,同时移除jitpack.io(因为之前尝试从jitpack.io下载失败,而且我们更换了依赖,现在使用中央仓库和阿里云仓库应该足够)注意:原pom.xml中已经有一个<repositories>,里面包含了jitpack.io和aliyun。我们要将其替换为新的配置(添加central,保留aliyun,移除jitpack.io)。具体步骤:-替换<repositories>标签内的内容为提供的新的仓库配置。-在<build><plugins>中,为maven-compiler-plugin添加<version>3.11.0</version>。另外,我们已经将ksoap2的依赖更换为:<dependency><groupId>com.google.code.ksoap2</groupId><artifactId>ksoap2-j2se-core</artifactId><version>3.6.2</version></dependency>下面我们将修改后的完整pom.xml给出。</think>###

2. **编译器插件修复**: - 添加了版本号 `3.11.0` 解决警告 - 保持 Java 1.8 兼容性 - 保留了原有的编译器参数配置 3. **依赖项更新**: - 使用 `ksoap2-j2se-core:3.6.2` 替代之前不可用的依赖 - 保留了其他所有依赖项不变 ### 验证和使用建议 1. **强制更新依赖**: ```bash mvn clean package -U ``` 2. **如果仍遇到问题**: - 清除本地仓库缓存: ```bash rm -rf ~/.m2/repository/com/google/code/ksoap2/ ``` - 使用依赖树分析: ```bash mvn dependency:tree -Dverbose -Dincludes=com.google.code.ksoap2 ``` 3. **长期维护建议**: - 统一 Spring 版本(目前有多个不同版本) - 升级 Log4j 到 2.x 版本(解决安全漏洞) - 使用 Maven 的 dependencyManagement 管理版本 ### 项目健康检查建议 ```xml <!-- 在 <properties> 中添加 --> <properties> <spring.version>4.3.30.RELEASE</spring.version> <log4j.version>2.17.1</log4j.version> </properties> <!-- 在 <dependencyManagement> 中管理版本 --> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-framework-bom</artifactId> <version>${spring.version}</version> <type>pom</type> <scope>import</scope> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-bom</artifactId> <version>${log4j.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> ``` ###
