[英]How to remove data source warnings in Spring Jpa and Intellij Idea?
After new update Intellij, I have red warnings in entity classes.新更新 Intellij 后,我在实体类中有红色警告。 For example:
例如:
@OneToMany(fetch = FetchType.LAZY)
@JoinTable(name = "poll_answers", joinColumns = @JoinColumn(name = "poll_id"))
private Set<String> answers;
I have warning lines under "poll_answers" and "poll_id" "cannot resolve table/column" and offers me press "assign data source".我在“poll_answers”和“poll_id”下有警告行“无法解析表/列”并让我按“分配数据源”。
Since your Spring project uses JPA and you are defining object-relational-mappings (ORM) using annotations:由于您的 Spring 项目使用 JPA,并且您正在使用注释定义对象关系映射 (ORM):
@JoinTable(name = "poll_answers", joinColumns = @JoinColumn(name = "poll_id"))
IntelliJ is intelligent and tries to validate the specified tables and columns against the database . IntelliJ 是智能的,它尝试根据数据库验证指定的表和列。
You can get an idea of the magic from this tutorial , although the topic is slightly going into another direction.您可以从本教程 中了解魔术,尽管该主题稍微转向了另一个方向。
You did not really provide the settings/setup (JPA Facet, etc.) that you are using within your IntelliJ project.您并未真正提供您在 IntelliJ 项目中使用的设置/设置(JPA Facet 等)。 It would be ideal if you can provide more information or a screenshot.
如果您能提供更多信息或屏幕截图,那将是理想的。
Since you apparently have no database/data-source assigned within your IntelliJ Database Tools window, the above explained validation fails and the reported warning is shown:由于您的IntelliJ 数据库工具窗口中显然没有分配数据库/数据源,因此上述验证失败并显示报告的警告:
cannot resolve table/column
无法解析表/列
A solution may be, to add the Data Source as the warning popup suggests already.一个解决方案可能是,按照警告弹出窗口的建议添加数据源。
Maybe this tutorial can help you to setup a new Data Source within IntelliJ Database Tools .也许本教程可以帮助您在IntelliJ 数据库工具中设置新的数据源。 You can use your JDBC connetion-string (starting with
jdbc://
) from your mentioned application.properties
to configure your database-connection.您可以使用您提到的
application.properties
的JDBC 连接字符串(以jdbc://
开头)来配置数据库连接。
In my comment to your question I also pointed you to this answer here, which pictorally describes how to Assign Data Sources via the IntelliJ menu: View -> Tool Windows -> Persistence .在我对您的问题的评论中,我还向您指出了这个答案,它以图解方式描述了如何通过 IntelliJ 菜单分配数据源: View -> Tool Windows -> Persistence 。
If you want to ignore such warnings without having to configure a data-source inside IntelliJ you can do that by removing the particular inspection in Settings under : Editor > Inspections
.如果您想忽略此类警告而不必在 IntelliJ 中配置数据源,您可以通过删除 Settings 下的特定检查来做到这一点:
Editor > Inspections
。
The proper selector should be under: JPA > Unresolved database references in annotations
正确的选择器应该在:
JPA > Unresolved database references in annotations
