Question

我正在从http://www.mkyong.com/spring-batch/spring-batch-example-csv-file-to-database/开发相同的 Spring Batch 代码（尚未定制），但使用所有当前最新的依赖项。

运行具有最新依赖项的代码时，会出错。

Answer 1

元数据表是自动初始化的，但不是业务表（RAW_REPORT）。默认的DDL（schema-mysql.sql和schema-drop-mysql.sql）只有Spring-Batch表。

检查下面的Spring-Batch源文件夹，了解* .sql包含的内容。

弹簧分批芯\ SRC \主\资源\有机\ springframework的\批次\芯\

您可以为业务数据定义新的DDL脚本，然后在database.xml配置中将其添加如下;

<!-- create job-meta tables automatically -->
<jdbc:initialize-database data-source="dataSource">
    <jdbc:script location="org/springframework/batch/core/schema-drop-mysql.sql" />
    <jdbc:script location="org/springframework/batch/core/schema-mysql.sql" />
    <jdbc:script location="schema-business-mysql.sql" />

schema-business-mysql.sql将具有 CREATE TABLE RAW_REPORT（....

Answer 2

错误非常明显。

Table 'test.raw_report' doesn't exist

您必须手动创建表。就像下面的方式

CREATE TABLE `schema_name`.`raw_report` (
`id` INT NOT NULL AUTO_INCREMENT,
`date` VARCHAR(45) NULL,
`impressions` VARCHAR(45) NULL,
`clicks` VARCHAR(45) NULL,
`earning` VARCHAR(45) NULL,
PRIMARY KEY (`id`));

这将解决您的问题。
