BeanInitializationException：bean需要属性

时间：2014-05-13 19:28:41

标签： spring spring-batch job-scheduling spring-scheduled

我得到了：

BeanInitializationException: Property 'job' is required for bean 'jobScheduler'

即使我有一个正确定义的“batch：job”bean，我也有一个指向它的属性声明，如下所示：

<batch:job id="userSummary">
    ...
</batch:job>

<bean id="jobScheduler" class="cc.glance.server.business.fact.JobScheduler">
    <property name="job" ref="userSummary" />
</bean>

注意：“userSummary”的定义应该没有问题，因为它之前工作正常，当我通过Web控制器调用它而不是调度时。

JobScheduler类：

public class JobScheduler
{
    @Autowired
    private JobLauncher jobLauncher;

    private Job job;

    private final Logger logger = LoggerFactory.getLogger(getClass());

    @Required
    public void setJob(Job job)

正如@AndreiStefan建议的那样，问题在于如何加载spring XML文件。

我没有加载我在这里复制的XML（使用＆＃34; userSummary＆＃34; job和＆＃34; jobScheduler＆＃34; bean）。它只是从另一个XML引用，将其设置为＆＃34; AutomaticJobRegistrar＆＃34;它扫描它的工作（只有工作，没有其他豆）。这就是我在网页控制器中工作的原因，正如我在问题中所说的那样。现在＆＃34; jobScheduler＆＃34;我定义的bean没有工作，所以它没有按照我想要的属性集加载。

现在我已将JobScheduler类注释为@Component。这就是上下文仍然加载它的原因，尽管没有必需的属性，从而引发了异常。

为解决这个问题，我移动了＆＃34; jobScheduler＆＃34;定义到上下文正在加载的另一个XML（它是在applicationContext.xml导入的文件夹上）。

答案 1 :(得分：0)

回答与@Vituel类似的问题。为了更具体一点，我既加载了XML文件和中定义的bean，又指定为@Component。即使我正在适当地定义属性，它们也会按需要出现，而不是指定：

<bean id="newMappingFileController" class="...NewMappingFileController">
    <property name="sasMappingBO" ref="sasMappingBO" />
</bean>
...
Error...
Caused by: ...BeanInitializationException: Property 'sasMappingBO' is required...

对我来说，解决方案只是从类中删除@Component注释，并且工作正常。
