Question

当我尝试配置我的会话工厂时，我收到此错误，根据google的结果将javaee-api放在提供的范围内应解决问题，但它不会：/ 在您的特殊情况下，看起来javax.validation接口库在测试中是不可用的。可能他们没有在javaee-api中包含。如果是这种情况，请添加：

 <dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>1.0.0.GA</version>
    <scope>test</scope>

您必须提供验证API的实现：

import pandas as pd
import numpy as np

x = np.array([[  0.00000000e+00,   0.00000000e+00,   3.71301945e-01],
       [  0.00000000e+00,   1.00000000e+00,   3.17619162e-01],
       [  0.00000000e+00,  -1.00000000e+00,   3.11078923e-01],
       [  1.00000000e+00,   0.00000000e+00,   4.01434455e-01],
       [  1.00000000e+00,   1.00000000e+00,   3.16000976e-01],
       [  1.00000000e+00,  -1.00000000e+00,   2.82564558e-01],
       [  2.00000000e+00,   1.00000000e+00,   3.61490457e-01],
       [  2.00000000e+00,   0.00000000e+00,   3.24832048e-01],
       [  2.00000000e+00,  -1.00000000e+00,   3.13677513e-01]])

df = pd.DataFrame(x, columns=["id", "class", "p"])
df.pivot(index="id", columns="class", values="p")

您的版本可能会有所不同。

问候。

Answer 2

引起：java.lang.ClassFormatError：方法中缺少Code属性......

表示您使用的jar只包含类和方法签名，但不包含方法实现。见this
