当我使用 H2 数据库时，此方法在我的 Spring Boot 应用程序中运行良好：
方法
@Bean
public JdbcBatchItemWriter<PE> writer() {
JdbcBatchItemWriter<PE> itemWriter = new JdbcBatchItemWriter<PE>();
itemWriter.setDataSource(dataSource());
itemWriter.setSql("INSERT INTO PETABLE (TASK_ID, TASK_DESCRIPTION, ORIGINAL_DATE, POLICY_NO, BRAND_DESC, LOAN_NO, LINE_OF_BUSINESS, LAST_NAME, BUSINESS_RULE, BUSINESS_RULE_DESC) VALUES (:taskid, :taskdescription, :originaldate, :policyno, :branddescription, :loannumber, :lineofbusiness, :lastname, :businessrule, :businessruledescription)");
itemWriter.setItemSqlParameterSourceProvider(new BeanPropertyItemSqlParameterSourceProvider<PE>());
return itemWriter;
}
但是当我使用 SQL Server 时，它会抛出错误的 SQL 语法/无效的对象名称“BATCH_JOB_INSTANCE”错误。我在 SQL Server 中手动创建了 PETABLE。
SQL Server 数据库配置：
@Bean
public DataSource dataSource() {
DataSourceBuilder dataSourceBuilder = DataSourceBuilder.create();
dataSourceBuilder.driverClassName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
dataSourceBuilder.url("jdbc:sqlserver://termineserver:1433;databaseName=termineserverdatabase");
dataSourceBuilder.username("***");
dataSourceBuilder.password("***");
return dataSourceBuilder.build();
}
H2 数据库配置：
@Bean
public DataSource dataSource(){
EmbeddedDatabaseBuilder embeddedDatabaseBuilder = new EmbeddedDatabaseBuilder();
return embeddedDatabaseBuilder.addScript("classpath:org/springframework/batch/core/schema-drop-h2.sql")
.addScript("classpath:org/springframework/batch/core/schema-h2.sql")
.addScript("classpath:petable.sql")
.setType(EmbeddedDatabaseType.H2)
.build();
}
表创建
CREATE TABLE PETABLE (
TASK_ID VARCHAR(10),
TASK_DESCRIPTION VARCHAR(500),
ORIGINAL_DATE VARCHAR(100) ,
POLICY_NO VARCHAR(100),
BRAND_DESC VARCHAR(100),
LOAN_NO VARCHAR(100),
LINE_OF_BUSINESS VARCHAR(100),
LAST_NAME VARCHAR(100),
BUSINESS_RULE VARCHAR(100),
BUSINESS_RULE_DESC VARCHAR(100)
) ;
使用 MS-SQL 数据库时出错：

您需要创建 Spring Batch 所需的所有表。
