使用XML通过字符串以外的属性来配置Spring Bean（使用属性文件）

Question

I have a Spring Bean defined as:

<bean id="loyaltyPointsExpiringJobTrigger"  class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="name" value="Loyalty Points Expiring Job Trigger" />
        <property name="jobDetail" ref="loyaltyPointsExpiringJobDetail" />
        <property name="cronExpression" value="${prop.loyalty.expiring.points.job.cron}"/>
        <property name="timeZone" value="${prop.loyalty.expiring.points.timezone}"/>
    </bean>

However, the property prop.loyalty.expiring.points.timezone is causing TypeMismatchException with the message:

org.springframework.beans.TypeMismatchException: Failed to convert property value of type 'java.lang.String' to required type 'java.util.TimeZone' for property 'timeZone'; nested exception is java.lang.IllegalArgumentException: Invalid time zone specification '${prop.loyalty.expiring.points.timezone}'

Please guide.

Answer 1

这很简单，您可能需要为timeZone对象定义一个bean，并找出使用字符串的构造函数，并传递所需的值。
