为什么Eclipse建议将“Object”作为数据类型“Text”的默认映射类型？

标签： mysql eclipse java-ee dali

使用Eclipse（适用于Java EE开发人员的Juno 4.2）从表生成JPA实体时，它建议Object作为我设置为Text的属性的默认映射类型。
这非常烦人，因为我必须手动将它们全部设置为String 有人遇到过那种问题，知道该怎么办？这是一个错误吗？ Eclipse Indigo的行为并不像那样。

这是来自/runtime/vendors/MySql_5.1/MySql_5.1.xmi的{​​{1}} :(但根据此文件org.eclipse.datatools.enablement.mysql.dbdefinition_1.0.4.v201109022331.jar应该映射到Text这必须是错误的文件 - 但是如何查找出正确的？）

String

Dali（生成JPA实体的Eclipse部分）使用DTP（Eclipse的另一部分）来确定特定数据类型的Java属性类型。这些映射是特定于数据库平台的，并在各种DTP插件的.xmi文件中指定。

例如，在Juno中，对于PostgreSQL，数据类型ABSTIME被映射到文件中的Java类型java.lang.Object /runtime/vendors/postgresql/postgresql_8.x.xmi 在插件罐中 ./plugins/org.eclipse.datatools.enablement.postgresql.dbdefinition_1.0.2.v201110070445.jar。

根据您的数据库平台以及您安装的其他插件，这些设置可能在Indigo和Juno之间发生了变化。您可以提取相应的.xmi文件，对其进行编辑，然后将其返回到jar中，这应该会改变实体的生成方式。
