Spring Data JPA智能无法在Intellij中运行

Question

我已经使用Spring Data JPA设置了一个spring boot项目,但我没有看到Spring数据jpa的智能.

屏幕截图显示问题,我的餐厅实体有一个变量调用restaurantAddress,我试图让intelliJ帮助我完成编码,但没有智能显示.

我的项目设置如下:

申请类:

@SpringBootApplication
@ComponentScan(basePackages = {"com.mycompany"})
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

POM:

我在IntelliJ 15上安装了Spring Data插件,prject设置:

我通过添加JavaEE Persistence框架支持解决了这个问题.只需右键单击项目,选择Add Framework Support然后向下滚动以查找JavaEE Persistence,然后启用复选框并单击确定:

^{添加JavaEE Persistence Facet}

它会添加一个persistence.xml文件,你可以删除它.最后,您的自动完成将返回:

^{片刻的真相}

更新您还可以JPA在中启用构面Project Structure.首先,按Ctrl Alt Shift S或转到Files > Project Structure.点击Add按钮,然后在菜单中选择JPA:

^{添加JPA Facet}

终于打了OK.
