【中文标题】带有 Spring Data JPA 的 Spring Boot 为 Oracle 数据库上的 findOne(...) 提供了无效字符问题【英文标题】：Spring Boot with Spring Data JPA gives invalid character issue for findOne(…) on Oracle database 【发布时间】：2014-12-28 08:39:20 【问题描述】：我的设置：Spring Boot，使用 spring-data-jpa，Oracle 11g。我在 url 上提到了相同的设置，
http://spring.io/guides/gs/accessing-data-jpa/
它适用于 hsqldb。我想与 Oracle 合作。所以，我在 Oracle db 中创建了表。 但是，当我从内存/文件系统 hsqldb 切换到 Oracle 时。它给了我问题。

它生成的选择查询，可以在sqldeveloper中执行！谁能帮我解决这个问题？
更新 1
更新了上面 repository.findByName("test") 的详细堆栈跟踪。
我有一个带有我自己的数据源、EntityManagerFactory 和 TransactionManager 配置的 Spring Boot 设置。
如果我运行 findAll，它会起作用。 我还发现，当我执行裸选择查询时，例如
select * from customer where name = 'test'
有效！
但是，当我使用 namedParameterJdbcTemplate 并传递参数时，它会出现上述“无效字符”的问题！
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);
【问题讨论】：
您介意添加完整的堆栈跟踪吗？ 当然......添加堆栈跟踪和我收集的更多信息。 我建议您调试 Hibernate 类，并可能向他们提交一张票。似乎它正在生成无效的 SQL。 谢谢奥利弗。这有帮助。我发现了问题！它处于休眠状态。 【参考方案1】：看来，我对数据源属性集进行了一些额外的配置。
processEscapes -> 设置为 false。
当我打开它时，它给了我实际的问题。问题是，我命名的列之一（驼峰式）与表中（基于下划线）不同。
因此，在修复了休眠实体中的名称，使其基于下划线的名称之后，它终于起作用了！
@Entity 中定义的列名是 firstName。 而在表中，列名是 first_name。
只是因为我设置了 DriverManagerDataSource -> setConnectionProperties processEscapes = false
它给了我错误的信息！ 当我将其设置为 true 时，它给了我列标识符丢失的问题。这导致我修复它:)
【讨论】：
我设置了 hibernate.naming_strategy。 'ImprovedNamingStrategy' 但它似乎不适用于列命名！【参考方案2】：如果您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 keyfield = :paramName
