我正在尝试设置Spring Batch作业，该作业从Oracle DB读取然后写入xml。但它不会比阅读过程更进一步，我得到了这个例外：

引起：java.sql.SQLException：ORA-01453：SET TRANSACTION必须是第一个事务声明
我已经像这样实现了读者bean：
@Configuration
@EnableBatchProcessing
@Import(DataSourceConfiguration.class)
public class BatchConfiguration {
@Autowired
public DataSource dataSource;
@Bean
public JdbcCursorItemReader<LeaveBalanceDTO> reader(){
JdbcCursorItemReader<LeaveBalanceDTO> reader = new JdbcCursorItemReader<>();
String sql = "SELECT * FROM sapleave";
reader.setDataSource(dataSource);
reader.setSql(sql);
reader.setRowMapper(new BeanPropertyRowMapper<>(LeaveBalanceDTO.class));
return reader;
}
数据源配置如下所示
@PropertySource(value=("classpath:application.properties"))
public class DataSourceConfiguration {
@Autowired
Environment environment;
@Bean
public DataSource dataSource() {
return DataSourceBuilder
.create()
.driverClassName(environment.getProperty("CDL.driverClassName"))
.url(environment.getProperty("CDL.url"))
.username(environment.getProperty("CDL.username"))
.password(environment.getProperty("CDL.password"))
.build();
}
我认为SpringManagement是由Spring Batch使用@EnableBatchProcessing自动完成的。而且我也不认为选择查询甚至需要交易。有人知道出了什么问题？提前谢谢！
编辑而不是DataSourceBuilder我已经像这样实现了OracleDataSource：
@Bean
public DataSource dataSource() throws SQLException {
OracleDataSource dataSource = new OracleDataSource();
dataSource.setUser(environment.getProperty("CDL.username"));
dataSource.setPassword(environment.getProperty("CDL.password"));
dataSource.setURL(environment.getProperty("CDL.url"));
return dataSource;
}
但现在我收到了这个错误：
Caused by: org.springframework.dao.DataAccessResourceFailureException: Could not obtain sequence value; nested exception is java.sql.SQLSyntaxErrorException: ORA-02289: sequence does not exist
在启动应用程序时，我看到spring正在运行一个sql脚本，我想创建一个临时数据库：
2017-03-29 15:43:57.200 INFO 19332 --- [ main] o.s.jdbc.datasource.init.ScriptUtils : Executing SQL script from class path resource [org/springframework/batch/core/schema-oracle10g.sql]
2017-03-29 15:43:57.285 INFO 19332 --- [ main] o.s.jdbc.datasource.init.ScriptUtils : Executed SQL script from class path resource [org/springframework/batch/core/schema-oracle10g.sql] in 85 ms.
似乎有些序列正在那里创建。我不知道它是否与此问题有关，但我使用的是Oracle 9i来检索我的数据。对可能解决方案的任何想法谢谢！
答案 0 :(得分：0)
我通过阻止spring批处理将作业存储库存储在Oracle DB中来自行修复它。我所做的是让Spring创建一个嵌入式hsqldb来存储其作业仓库。我是基于这2个帖子做到的：
