我正在處理spring應用程序。我現在面臨的問題與數據庫連接，以獲得records.Below是例外：嘗試獲取數據時發生SQLException
Error org.springframework.jdbc.BadSqlGrammarException: StatementCallback; bad SQL grammar [SELECT dstoreNumber, details, VALUE FROM dstore.table1 where value='400s' ]; nested exception is java.sql.SQLException: ORA-00942: table or view does not exist
我連接到分別位於兩個不同的數據庫服務器，兩個不同的模式。
我在一個類中創建了兩個JdbcTemplate對象。以下是我的代碼。
spring-beans.properties
##### dstore Datasource #####
dstore.dataSource.url=jdbc:oracle:thin:@dstore1.dev.xyz.com:5150:dstore
dstore.dataSource.username=dstore
dstore.dataSource.password=password
##### dscon Datasource #####
dscon.dataSource.url=jdbc:oracle:thin:@dscon.dev.xyz.com:5150:dscon
dscon.dataSource.username=dscon
dscon.dataSource.password=password

Java類：在下面的類myDAO.getMethod2（）執行成功，但是當我打電話myDAO .getMethod1（），拋出異常「表或視圖不存在」。
@component
class LoadData{
@Inject
private MyDAO myDAO;
//Gets values from database
@PostConstruct
public void loadListCodes()
{
final List<MyDTO> listValues = myDAO.getMethod2(); //successfully connected to database
try {
final List<MyDTO> listValue = myDAO.getMethod1(); //unable to connect to Database, exception is thrown
LOG.info("Method1 : " + listValue);
} catch (Exception e) {
LOG.info("exception " + e);
System.out.println("exception is :: " + e);
}
//logic goes here
}
}
Java類：
@Repository
public class MyDAOJDBCImpl implements MyDAO
{
@Inject
@Qualifier("jdbcTemplateServicedstore")
private JdbcTemplate jdbcTemplate1;
@Inject
@Qualifier("jdbcTemplateServicedscon")
private JdbcTemplate jdbcTemplate2;
private static final String SQL1 = "SELECT dstoreNumber, details, VALUE FROM dstore.table1 "
+ "WHERE value = '400S' ";
private static final String SQL2 = "SELECT dsconNumber, details, VALUE FROM dscon.table1 "
+ "WHERE value = '700S' ";
public List<MyDTO> getMethod1()
{
//unable to connect to database, throwing exception
List<MyDTO> listValues = null;
LOG.info("Retrieving data..");
try
{
listValues = jdbcTemplate1.query(SQL1,
new RowMapper<ListValueDTO>()
{
public MyDTO mapRow(final ResultSet rs, final int rowNum) throws SQLException
{
final MyDTO listValueDTO = new MyDTO();
listValueDTO.setdstoreNumber(rs.getString("dstoreNumber));
listValueDTO.setDetails(rs.getString("details"));
listValueDTO.setValue(rs.getString("value"));
return listValueDTO;
}
});
}
catch (Exception e)
{
LOG.error("Error :" + e);
}
return listValues;
}
public List<MyDTO> getMethod2()
{
List<MyDTO> listValues = null;
LOG.info("Retrieving data..");
try
{
listValues = jdbcTemplate2.query(SQL2,
new RowMapper<ListValueDTO>()
{
public MyDTO mapRow(final ResultSet rs, final int rowNum) throws SQLException
{
final MyDTO listValueDTO = new MyDTO();
//code goes here
return listValueDTO;
}
});
}
catch (Exception e)
{
LOG.error("Error :" + e);
}
return listValues;
}
}
PS：我連接到分別位於兩個不同的數據庫服務器和不同的模式兩個不同的表。我想當我調用getMethod1（）時，它無法找到架構或無法連接到其他數據庫服務器。我該如何解決這個問題？任何人都需要面對這個問題。我需要在一個java類中調用並執行不同服務器中存在的不同數據庫表。
您是否使用TOAD和您的APP使用相同的Oracle用戶？ – reos
是的，你的意思是連接數據庫的憑據？@reos – Ran
是的，如果你可以在TOAD上執行語句，那麼你可以在你的應用程序中執行語句。可能您正在使用不同的用戶，或者您正在執行不同的聲明。 – reos
