红帽全球峰会319.4. 使用方法
当 Spring Batch 组件收到消息时，它会触发作业执行。该作业将使用 org.springframework.batch.core.launch.JobLaucher 实例按照以下算法解析：
-
如果在组件上手动设置
JobLauncher，则使用它。 -
如果在组件上设置了
jobLauncherRef选项，则使用给定名称搜索 Camel Registry for theJobLauncher。弃用并将在 Camel 3.0 中删除！ -
如果在 Camel Registry 中注册了
Job Launcher名称，则使用它。 -
如果以上步骤都不允许解析
JobLauncher，且 Camel Registry 中只有一个JobLauncher实例，则使用它。
消息中找到的所有标头都作为作业参数传递给 JobLauncher。字符串,Long,Double 和 java.util.Date 值被复制到 org.springframework.batch.core.JobParametersBuilder - other 数据类型转换为 Strings。
