spring-batch - 如何在没有 java 配置而不是 XML 的情况下使用 CommandLineJobRunner 启动 Spring 批处理

问题描述

我在 java 配置文件中有一个作业定义。当我尝试从 gradle 任务运行作业时，我得到 IOException parsing XML Document from class path。如何在没有 XML 配置的情况下使用 CommandLineJobRunner 运行作业？

摇篮

task executeJob(type: JavaExec) {
    main = 'org.springframework.batch.core.launch.support.CommandLineJobRunner'
    classpath = sourceSets.test.runtimeClasspath
    args = ["--job_path", "C:\\dev\\git\\ncf-bulk-order\\src\\main\\java\\com\\shelter\\NCFBulkOrder\\Jobs\\NCFBulkOrderConfig.java",
            "--job_id", "Response",
            "--next",
            "--customParam", "value"]
}

解决方案

CommandLineJobRunner需要 XML 文件或 Java 配置类，其中包含定义您的作业的 Spring 应用程序上下文。这是一个带有 Java 配置类的示例：

java -cp your/class/path \
     org.springframework.batch.core.launch.support.CommandLineJobRunner \
     com.example.MyJobConfiguration \
     myJob

所以在你的命令中，你不需要传递--job_path标志。
