Spring Boot with Spring Data JPA为Oracle数据库上的findOne(…)提供了无效字

Question

我的设置：Spring引导，使用Spring数据jpa，Oracle 11g。我有相同的设置在这里提到的网址，

http://spring.io/guides/gs/accessing-data-jpa/

它适用于hsqldb。我想与Oracle合作。因此，我在Oracle数据库中创建了该表。但是，当我从内存/文件系统中的hsqldb切换到Oracle时。这给了我问题。

它生成的选择查询可以在sqldeveloper中执行！有人能帮我吗？

更新1

更新了上面存储库的详细堆栈跟踪.findByName（"test"）.

我使用自己的数据源EntityManagerFactory&TransactionManager配置。

如果我运行findAll，它会起作用。我还发现，当我执行诸如之类的裸选择查询时

从客户中选择*，其中name="测试"

它有效！

但是，当我使用namedParameterJdbcTemplate并传递参数时，它会出现上面的"无效字符"问题！

String sql = "select * from customer where name = :name";
Map<String, Object> paramMap = new HashMap<String, Object>();
paramMap.put("name", "test");
List<Map<String,Object>> objList = namedParameterJdbcTemplate.queryForList(sql, paramMap);

Answer 1

看起来，我在数据源属性集上有一些额外的配置。

processEscapes->设置为false。

当我打开这个时，它给了我实际的问题。问题是，我对其中一列的命名（驼色大小写）与表中的不同（基于下划线）。

所以，在修复了hibernate实体中的名称，使其成为基于下划线的名称后，它终于成功了！

在@Entity中定义的列名为firstName。在表中，列名为first_name。

只是因为我用设置了DriverManagerDataSource->setConnectionPropertiesprocessEscapes=错误

它给了我错误的信息！当我把它变成true时，它给了我列标识符丢失的问题。这让我修复了它：）

Answer 2

如果在内部选择中使用位置参数（$1，$2），也会导致此错误。如

... FROM tablename WHERE keyfield= $1 and insert_date = ( select min (create_date) from tablename WHERE keyfield = $1)

从位置参数更改为命名参数可以解决问题，即…其中关键字字段= :paramName
