篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了spring注解配置quartz应用相关的知识，希望对你有一定的参考价值。
项目中会经常用到定时器，因此，其quartz的使用，我们必须要掌握。下面就以例子来讲解如何在spring中整合quartz，
使用注解配置的方式来实现定时执行任务。
一、引入jar包
项目中需引入quartz的jar包，由于整合到spring中，肯定也引入了spring的相关jar包。
例子中引用的是quartz-2.1.1版本，使用maven管理项目，pom文件需引入quartz依赖
二、spring配置文件中配置 （applicationContext.xml）
1） xmlns和 xsi:schemaLocation配置
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsd "
2）task任务扫描注解
<!-- 加载定时任务 -->
<task:annotation-driven/>
3）扫描的位置
<!-- 自动扫描 -->
<context:component-scan base-package="com.hik.quartz"/>
4）写任务实现类及配置任务定时执行方式
使用spring注解配置quartz，非常方便实用。
下面给出配置spring配置文件配置

同时给出quartz的CronExpression类的源码，可以知道并理解怎样去配置自己想要的定时执行任务方式

For example, "*" 102 * in the minute field means "every minute". 103 * <P> 104 * The \'?\' character is allowed for the day-of-month and day-of-week fields. It 105 * is used to specify \'no specific value\'. This is useful when you need to 106 * specify something in one of the two fields, but not the other. 107 * <P> 108 * The \'-\' character is used to specify ranges For example "10-12" in 109 * the hour field means "the hours 10, 11 and 12". 110 * <P> 111 * The \',\' character is used to specify additional values. For example 112 * "MON,WED,FRI" in the day-of-week field means "the days Monday, 113 * Wednesday, and Friday". 114 * <P> 115 * The \'/\' character is used to specify increments. For example "0/15" 116 * in the seconds field means "the seconds 0, 15, 30, and 45". And 117 * "5/15" in the seconds field means "the seconds 5, 20, 35, and 118 * 50". Specifying \'*\' before the \'/\' is equivalent to specifying 0 is 119 * the value to start with. Essentially, for each field in the expression, there 120 * is a set of numbers that can be turned on or off. For seconds and minutes, 121 * the numbers range from 0 to 59. For hours 0 to 23, for days of the month 0 to 122 * 31, and for months 1 to 12. The "/" character simply helps you turn 123 * on every "nth" value in the given set. Thus "7/6" in the 124 * month field only turns on month "7", it does NOT mean every 6th 125 * month, please note that subtlety. 126 * <P> 127 * The \'L\' character is allowed for the day-of-month and day-of-week fields. 128 * This character is short-hand for "last", but it has different 129 * meaning in each of the two fields. For example, the value "L" in 130 * the day-of-month field means "the last day of the month" - day 31 131 * for January, day 28 for February on non-leap years. If used in the 132 * day-of-week field by itself, it simply means "7" or 133 * "SAT". But if used in the day-of-week field after another value, it 134 * means "the last xxx day of the month" - for example "6L" 135 * means "the last friday of the month". You can also specify an offset 136 * from the last day of the month, such as "L-3" which would mean the third-to-last 137 * day of the calendar month. <i>When using the \'L\' option, it is important not to 138 * specify lists, or ranges of values, as you\'ll get confusing/unexpected results.</i> 139 * <P> 140 * The \'W\' character is allowed for the day-of-month field. This character 141 * is used to specify the weekday (Monday-Friday) nearest the given day. As an 142 * example, if you were to specify "15W" as the value for the 143 * day-of-month field, the meaning is: "the nearest weekday to the 15th of 144 * the month". So if the 15th is a Saturday, the trigger will fire on 145 * Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the 146 * 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th. 147 * However if you specify "1W" as the value for day-of-month, and the 148 * 1st is a Saturday, the trigger will fire on Monday the 3rd, as it will not 149 * \'jump\' over the boundary of a month\'s days. The \'W\' character can only be 150 * specified when the day-of-month is a single day, not a range or list of days. 151 * <P> 152 * The \'L\' and \'W\' characters can also be combined for the day-of-month 153 * expression to yield \'LW\', which translates to "last weekday of the 154 * month". 155 * <P> 156 * The \'#\' character is allowed for the day-of-week field. This character is 157 * used to specify "the nth" XXX day of the month. For example, the 158 * value of "6#3" in the day-of-week field means the third Friday of 159 * the month (day 6 = Friday and "#3" = the 3rd one in the month). 160 * Other examples: "2#1" = the first Monday of the month and 161 * "4#5" = the fifth Wednesday of the month. Note that if you specify 162 * "#5" and there is not 5 of the given day-of-week in the month, then 163 * no firing will occur that month. If the \'#\' character is used, there can 164 * only be one expression in the day-of-week field ("3#1,6#3" is 165 * not valid, since there are two expressions). 166 * <P> 167 * <!--The \'C\' character is allowed for the day-of-month and day-of-week fields. 168 * This character is short-hand for "calendar". This means values are 169 * calculated against the associated calendar, if any. If no calendar is 170 * associated, then it is equivalent to having an all-inclusive calendar. A 171 * value of "5C" in the day-of-month field means "the first day included by the 172 * calendar on or after the 5th". A value of "1C" in the day-of-week field 173 * means "the first day included by the calendar on or after Sunday".--> 174 * <P> 175 * The legal characters and the names of months and days of the week are not 176 * case sensitive. 177 * 178 * <p> 179 * <b>NOTES:</b> 180 * <ul> 181 * <li>Support for specifying both a day-of-week and a day-of-month value is 182 * not complete (you\'ll need to use the \'?\' character in one of these fields). 183 * </li> 184 * <li>Overflowing ranges is supported - that is, having a larger number on 185 * the left hand side than the right. You might do 22-2 to catch 10 o\'clock 186 * at night until 2 o\'clock in the morning, or you might have NOV-FEB. It is 187 * very important to note that overuse of overflowing ranges creates ranges 188 * that don\'t make sense and no effort has been made to determine which 189 * interpretation CronExpression chooses. An example would be 190 * "0 0 14-6 ? * FRI-MON". </li> 191 * </ul> 192 * </p> 193 * 194 * 195 * @author Sharada Jambula, James House 196 * @author Contributions from Mads Henderson 197 * @author Refactoring from CronTrigger to CronExpression by Aaron Craven 198 */ 199 public final class CronExpression implements Serializable, Cloneable { 200 201 private static final long serialVersionUID = 12423409423L; 202 203 protected static final int SECOND = 0; 204 protected static final int MINUTE = 1; 205 protected static final int HOUR = 2; 206 protected static final int DAY_OF_MONTH = 3; 207 protected static final int MONTH = 4; 208 protected static final int DAY_OF_WEEK = 5; 209 protected static final int YEAR = 6; 210 protected static final int ALL_SPEC_INT = 99; // \'*\' 211 protected static final int NO_SPEC_INT = 98; // \'?\' 212 protected static final Integer ALL_SPEC = ALL_SPEC_INT; 213 protected static final Integer NO_SPEC = NO_SPEC_INT; 214 215 protected static final Map<String, Integer> monthMap = new HashMap<String, Integer>(20); 216 protected static final Map<String, Integer> dayMap = new HashMap<String, Integer>(60); 217 static { 218 monthMap.put("JAN", 0); 219 monthMap.put("FEB", 1); 以上是关于spring注解配置quartz应用的主要内容，如果未能解决你的问题，请参考以下文章
