Question

需要有关Quartz调度程序的帮助。这是我到目前为止所做的。

Spring定义

<bean id="firstClass" class="com.my.sample.FirstClass">
    // some properties
</bean>

<bean id="secondClass" class="com.my.sample.SecondClass">
    // some properties
</bean>

<bean id="myJob" class="org.springframework.scheduling.quartz.JobDetailBean">
    <property name="jobClass" value="com.my.sample.quartz.job.MyJob" />
    <property name="jobDataAsMap">
        <map>
            <entry key="firstClass" value-ref="firstClass" />
            <entry key="secondClass" value-ref="secondClass" />
        </map>
    </property>
</bean>

<bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
    <property name="jobDetail" ref="myJob" />
    <property name="repeatInterval" value="10000" />
    <property name="startDelay" value="1000" />
</bean>

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="quartzProperties" ref="quartzProperties" />
    <property name="jobDetails">
        <list><ref bean="myJob" /></list>
    </property>
    <property name="triggers">
        <list><ref bean="simpleTrigger" /></list>
    </property>
</bean>

类实现

public class MyJob extends QuartzJobBean {

    private static final Logger LOGGER = LoggerFactory.getLogger(MyJob.class);

    private FirstClass firstClass;
    private SecondClass secondClass;

    @Override
    protected void executeInternal(final JobExecutionContext jobExecutionContext) throws JobExecutionException {
        LOGGER.info("Executing job...");

        final AbcClass abcClass = firstClass.getAbc();
        secondClass.testMethod(abcClass);

    }

    public void setFirstClass(final FirstClass firstClass) {
        this.firstClass = firstClass;
    }

    public void setSecondClass(final SecondClass secondClass) {
        this.secondClass = secondClass;
    }
}

public interface MyParent {

    AbcClass getAbc();

}

public class FirstClass implements MyParent, Serializable {

    AbcClass getAbc() {
        // generate abcClass from db

        return abcClass;
    }

}

但是我收到了这样的错误

org.springframework.beans.factory.BeanCreationException：在URL [bundle：//343.0：0 / META-INF / spring / osgi]中定义名称为'org.springframework.scheduling.quartz.SchedulerFactoryBean＃0'的bean创建错误.xml]：调用init方法失败;嵌套异常是org.quartz.JobPersistenceException：无法为'dataSyncJob'作业存储触发器'simpleTrigger'：com.my.sample.MyParent [请参阅嵌套异常：java.lang.ClassNotFoundException：com.my.sample.MyParent] 在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean（AbstractAutowireCapableBeanFactory.java:1455）[428：org.springframework.beans：3.1.4.RELEASE] ...

项目结构

com.my
    |-sample
        |-MyParent.java
        |-FirstClass.java
        |-SecondClass.java
        |-quartz.job
            |-MyJob.java
    |-other

捆绑配置

<configuration>
    <instructions>
        <Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
        <Import-Package>
            org.quartz.impl.jdbcjobstore.oracle,
            org.quartz.simpl,
            org.quartz.impl.jdbcjobstore,
            *
        </Import-Package>
        <Export-Package>com.my.*</Export-Package>
        <excludeDependencies>*;scope=provided|runtime</excludeDependencies>
        <DynamicImport-Package>
            org.apache.cxf.*,
            org.springframework.beans.*
        </DynamicImport-Package>
    </instructions>
</configuration>

看起来你正在做osgi，你需要确保：

已部署包含com.my.sample.MyParent类的包。
使用MyParent类的bundle在Import-Package部分下的MANIFEST.MF文件中导入包com.my.sample。

如果您使用的是Maven，则可以使用Apache Felix maven-bundle-plugin操作MANIFEST.MF文件。

在Quartz调度程序中存储触发器时ClassNotFoundException
