Java 尝试获取数据时发生SQLException

我正在研究spring应用程序。我面临连接数据库以获取记录的问题。以下是例外情况：

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

我正在连接两个不同的模式，它们位于两个不同的数据库服务器中。

我在一个类中创建了两个JdbcTemplate对象。下面是我的代码

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

PS：我连接到两个不同的表，它们位于两个不同的数据库服务器和不同的模式中找不到架构或无法连接到其他数据库服务器。如何解决此问题？以前有人遇到过此问题。我需要在单个java类中调用并执行不同服务器中的不同数据库表。

异常

ORA-00942:表或视图不存在

通常意味着表不存在，例如例如，您在表名中犯了错误，或者您没有权限从此表中选择。

我有一个表，我有权限。.我可以在TOAD中执行查询并获得结果。.我猜我上面提到的代码中的某些映射是错误的。您在TOAD和您的应用程序中使用的是同一个Oracle用户吗？是的，您的意思是要使用的凭据连接到数据库？@reosys，如果您可以在TOAD上执行该语句，那么您可能会在应用程序中执行该语句。可能您使用的是其他用户或执行的是其他语句。
