我在应用程序中陷入了Spring Boot的困境，不想运行架构或表，仅连接到数据库SQL Server和查询信息，因此我在文件application.properties中禁用了这一行
spring.batch.initialize-schema=never
spring.datasource.initialization-mode=never
但是不起作用，我不知道出了什么问题，已经配置了我的数据源，在此先感谢您， 我希望有人能帮助我，对不起我的英语不好。
我正在使用Spring Boot 2.2.6，我的DataSourceConfiguration代码
.....
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
public class DataSourceConfiguration {
@Bean
@Primary
@Qualifier("jobsDataSource")
public DataSource hsqldbDataSource() throws SQLException {
final SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
dataSource.setDriver(new org.hsqldb.jdbcDriver());
dataSource.setUrl("jdbc:hsqldb:mem:mydb");
dataSource.setUsername("sa");
dataSource.setPassword("");
return dataSource;
}
@Bean
public JdbcTemplate jdbcTemplate(final DataSource dataSource) {
return new JdbcTemplate(dataSource);
}
@Bean
@Qualifier("sqlserverDataSource")
public DataSource sqlserverDataSource() throws SQLException {
final SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
dataSource.setDriver(new net.sourceforge.jtds.jdbc.Driver());
dataSource.setUrl("jdbc:jtds:sqlserver://x.y.z.t:1433/mydb");
dataSource.setUsername("usersqlserver");
dataSource.setPassword("xxxxxx");
return dataSource;
}
@Bean
public JdbcTemplate sqlJdbcTemplate(@Qualifier("sqlserverDataSource") final DataSource dataSource) {
return new JdbcTemplate(dataSource);
}
public PlatformTransactionManager transactionManager(){
return new ResourcelessTransactionManager();
}
@Bean
public BatchConfigurer configurer(@Qualifier("sqlserverDataSource") DataSource dataSource){
return new DefaultBatchConfigurer(){
@Override
protected JobRepository createJobRepository() throws Exception {
JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
factory.setDataSource(dataSource);
factory.setTransactionManager(transactionManager());
return factory.getObject();
// MapJobRepositoryFactoryBean mapJobRepositoryFactoryBean = new MapJobRepositoryFactoryBean(transactionManager());
// mapJobRepositoryFactoryBean.setTransactionManager(transactionManager());
// return mapJobRepositoryFactoryBean.getObject();
}
@Override
protected JobLauncher createJobLauncher() throws Exception {
SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
jobLauncher.setJobRepository(createJobRepository());
jobLauncher.setTaskExecutor(new SimpleAsyncTaskExecutor());
jobLauncher.afterPropertiesSet();
return jobLauncher;
}
};
}
}
这是错误

好的，我已经删除了这一行，并且按照您的建议进行了操作，并且它起作用了，只是dao是NullpointerException，它的接口并在Itemprocessor中使用：
@Bean
public BatchConfigurer configurer(@Qualifier("sqlserverDataSource") DataSource dataSource){
return new DefaultBatchConfigurer(){
// @Override
// protected JobRepository createJobRepository() throws Exception {
// JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
// factory.setDataSource(dataSource);
// factory.setTransactionManager(transactionManager());
// // factory.setIsolationLevelForCreate("ISOLATION_READ_COMMITTED");
// //factory.setTablePrefix("dbo.tmpAccWebServ");
// //factory.setDatabaseType("SQLSERVER");
// //factory.setMaxVarCharLength(1000);
// return factory.getObject();
//// MapJobRepositoryFactoryBean mapJobRepositoryFactoryBean = new MapJobRepositoryFactoryBean(transactionManager());
//// mapJobRepositoryFactoryBean.setTransactionManager(transactionManager());
//// return mapJobRepositoryFactoryBean.getObject();
// }
//
// @Override
// protected JobLauncher createJobLauncher() throws Exception {
// SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
// jobLauncher.setJobRepository(createJobRepository());
// jobLauncher.setTaskExecutor(new SimpleAsyncTaskExecutor());
// jobLauncher.afterPropertiesSet();
// return jobLauncher;
// }
@Override
public void setDataSource(DataSource dataSource) {
// override to do not set datasource even if a datasource exist.
// initialize will use a Map based JobRepository (instead of database)
} //
};
}//
@Bean
public BatchConfigurer configurer(@Qualifier("sqlserverDataSource") DataSource dataSource){
return new DefaultBatchConfigurer(){
// @Override
// protected JobRepository createJobRepository() throws Exception {
// JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
// factory.setDataSource(dataSource);
// factory.setTransactionManager(transactionManager());
// // factory.setIsolationLevelForCreate("ISOLATION_READ_COMMITTED");
// //factory.setTablePrefix("dbo.tmpAccWebServ");
// //factory.setDatabaseType("SQLSERVER");
// //factory.setMaxVarCharLength(1000);
// return factory.getObject();
//// MapJobRepositoryFactoryBean mapJobRepositoryFactoryBean = new MapJobRepositoryFactoryBean(transactionManager());
//// mapJobRepositoryFactoryBean.setTransactionManager(transactionManager());
//// return mapJobRepositoryFactoryBean.getObject();
// }
//
// @Override
// protected JobLauncher createJobLauncher() throws Exception {
// SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
// jobLauncher.setJobRepository(createJobRepository());
// jobLauncher.setTaskExecutor(new SimpleAsyncTaskExecutor());
// jobLauncher.afterPropertiesSet();
// return jobLauncher;
// }
@Override
public void setDataSource(DataSource dataSource) {
// override to do not set datasource even if a datasource exist.
// initialize will use a Map based JobRepository (instead of database)
} //
};
}//
这是CustomerItemProcessor的代码
public class CustomerItemProcessor implements ItemProcessor<beangenerico,ThreadLocal<CopyOnWriteArrayList<beanCustomer>>> {
@Autowired
private CustomerDAO customerDAO;
private ThreadLocal<CopyOnWriteArrayList<beanCustomer>> listbean = new ThreadLocal<CopyOnWriteArrayList<beanCustomer>>();
public ThreadLocal<CopyOnWriteArrayList<beanCustomer>> process(beangenerico rangos) throws Exception {
System.out.println("entro a customitemprocessor");
listbean.set(new CopyOnWriteArrayList<beanCustomer>());
System.out.println("rangos:"+rangos.getIni()+"-"+rangos.getFin());
listbean = customerDAO.getAccAgentes(rangos);
if(listbean != null) {
//customer.setId(currentCustomer.getId());
return listbean;
} else {
return null;
}
}
@Autowired
public void setCustomerDAO(CustomerDAOImpl customerDAO) {
this.customerDAO = customerDAO;
}
}
这是接口的代码
public class CustomerItemProcessor implements ItemProcessor<beangenerico,ThreadLocal<CopyOnWriteArrayList<beanCustomer>>> {
@Autowired
private CustomerDAO customerDAO;
private ThreadLocal<CopyOnWriteArrayList<beanCustomer>> listbean = new ThreadLocal<CopyOnWriteArrayList<beanCustomer>>();
public ThreadLocal<CopyOnWriteArrayList<beanCustomer>> process(beangenerico rangos) throws Exception {
System.out.println("entro a customitemprocessor");
listbean.set(new CopyOnWriteArrayList<beanCustomer>());
System.out.println("rangos:"+rangos.getIni()+"-"+rangos.getFin());
listbean = customerDAO.getAccAgentes(rangos);
if(listbean != null) {
//customer.setId(currentCustomer.getId());
return listbean;
} else {
return null;
}
}
@Autowired
public void setCustomerDAO(CustomerDAOImpl customerDAO) {
this.customerDAO = customerDAO;
}
}
这是如果CustomerDAOImpl的代码
public interface CustomerDAO {
ThreadLocal<CopyOnWriteArrayList<beanCustomer>> getAccAgentes(beangenerico bean);
}
public interface CustomerDAO {
ThreadLocal<CopyOnWriteArrayList<beanCustomer>> getAccAgentes(beangenerico bean);
}
预先感谢您的帮助。

Spring Batch需要数据库中的一些表才能运行。因此，您需要预先手动创建这些表，或者告诉Spring Boot为您完成这些工作。
由于您已告诉Spring Boot不要通过设置spring.batch.initialize-schema=never为您创建这些表，因此您需要在目标数据源中自行创建它们。
因此，在您的情况下，您需要先运行DDL script在SQL Server实例上创建前创建Spring Batch表。
