ssh使用 TimerTask空指针错误

TimerTask run里面调用这个类方法的地方的代码发出来看下. 你是怎么获取当前类实例的(AutoComment2)

不好意思，看不太懂。。
Spring里我是这么配置的。

    <bean id="synchroDataTimerTask" class="com.surfkj.wlgzbx.action.AutoComment2"/>

    
    <bean id="scheduledDayDataTimerJob" class="org.springframework.scheduling.timer.ScheduledTimerTask">
        <property name="timerTask">
            <ref bean="synchroDataTimerTask" />
        </property>
        <property name="delay">
            <value>10000</value>
        </property>
        <property name="period">
            <value>1000000</value>
        </property>
    </bean>

    
    <bean class="org.springframework.scheduling.timer.TimerFactoryBean">
        <property name="scheduledTimerTasks">
            <list>
                <ref bean="scheduledDayDataTimerJob"/>
            </list>
        </property>
    </bean>
</beans>整个autocomment2是这样的。

        e.printStackTrace();

}
    }

public void setErrorApply(ErrorApplyInfo errorApply) {
this.errorApply = errorApply;
}
public IErrorApplyService getErrorApplyService() {
return errorApplyService;
}
public void setErrorApplyService(IErrorApplyService errorApplyService) {
this.errorApplyService = errorApplyService;
}}我是直接开启服务器就调用这个run。

synchroDataTimerTask 里面没有注入errorApplyService.加个@Autowired注解试下,不行就在
<bean id="synchroDataTimerTask" class="com.surfkj.wlgzbx.action.AutoComment2"></bean>里面把errorApplyService属性加上

肯定是 errorApplyService 没注入

另外建议不要开启服务器就调用这个run

嗯。是没有注入。已经改好了。十分谢谢。
顺便问下。我想做的是自动评价，就是服务器后台自动搜索符合条件的，然后修改数据库里评价这个字段。如果不是开启服务器就调用这个run，该怎么操作比较好?

调试易
