Question

我定义了一些实体，并希望现在生成表格。

我使用Eclipselink 2.5（JPA 2.1）和Glassfish 4.0，我的程序使用JKD7。

当我构建应用程序时，会出现以下消息：

warning: Supported source version 'RELEASE_6' from annotation processor 'org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor' less than -source '1.7'

Note: Creating static metadata factory ...

Note: Optional file was not found: META-INF/orm.xml continuing with generation.
Note: Optional file was not found: META-INF/eclipselink-orm.xml continuing with generation.

我不知道我现在需要做什么......

我有最新的EclipseLink版本
最新版本的glassfish
jkd 7
只是标准德比数据库（随glassfish 4.0提供）

我该如何解决这个问题？

<properties>
  <property name="eclipselink.ddl-generation" value="drop-and-create-tables"/>
  <property name="eclipselink.ddl-generation.output-mode" value="database"/>
</properties>

Answer 1

将这些行放在persistance.xml中：

<property name="eclipselink.ddl-generation" value="create-tables" />
<property name="eclipselink.ddl-generation.output-mode" value="database" />
<property name="eclipselink.ddl-generation-mode" value="ddl_database_generation" />

Answer 2

我遇到了同样的问题，找到了解决方案 here。在 netbeans 上更改此设置：
def generate_fft_data(data,labels, n_seconds_split=3): x = 256 * n_seconds_split y = 16 z = 48 * int(6/n_seconds_split) data = data.transpose(2,0,1).reshape(x,y,z).transpose(2,0,1) fft_data = [] for electrode in range(data.shape[2]): y_t = fft(data[:,:,electrode]) fft_data.append(np.abs(y_t)) sum_of_ffts = np.add.reduce(fft_data) return sum_of_ffts

EclipseLink不生成表
