使用ClassLoader.class加载密钥时出现错误，为什么？
UnitTest路径=“ /..../资源/..../key.der
版本部署路径= classLoader.getResource（AESKeyPath）;
（aESKeyPath =“ key.der”）
private void loadKey(final String AESKeyPath, final String privateKeyFileDerPath) {
Properties prop = new Properties();
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
InputStream input = classLoader.getResourceAsStream("foo.properties");
prop.load(input);
final String classpath = prop.getProperty("test.foo");
File aESKeyFile = null;
File privateKeyFile = null;
// My version deployed using the if.
if (classpath.equals("local")) {
URL aesKeyPath = classLoader.getResource(AESKeyPath);
if (aesKeyPath != null) {
aESKeyFile = new File(aesKeyPath.toURI());
}
URL privateKeyURL = classLoader.getResource(privateKeyFileDerPath);
if (privateKeyURL != null) {
privateKeyFile = new File(privateKeyURL.toURI());
}
// The tests used the else
} else {
aESKeyFile = new File(AESKeyPath);
privateKeyFile = new File(privateKeyFileDerPath);
}
byte[] encodedKey = new byte[(int) privateKeyFile.length()];
new FileInputStream(privateKeyFile).read(encodedKey);
PKCS8EncodedKeySpec privateKeySpec = new PKCS8EncodedKeySpec(encodedKey);
KeyFactory kf = KeyFactory.getInstance("RSA");
PrivateKey pk = kf.generatePrivate(privateKeySpec); <---- Error
pkCipher.init(Cipher.DECRYPT_MODE, pk);
aesKey = new byte[AES_Key_Size / 8];
CipherInputStream is = new CipherInputStream(new FileInputStream(AESKeyFile), pkCipher);
is.read(aesKey);
aeskeySpec = new SecretKeySpec(aesKey, "AES");
}
我的单元测试通过了，但是当我部署并使用'ClassLoader加载文件时，它给了我这个错误：

我比较前10个字节，并且相等。并且最后也具有相同的尺寸。
我使用以下命令生成密钥：
openssl genrsa -out private.pem 2048
openssl pkcs8 -topk8 -in private.pem -outform DER -out private.der -nocrypt
openssl rsa -in private.pem -pubout -outform DER -out public.der
我的问题是Maven。Maven对我的密钥进行编码。我通过在pom.xml中添加用于资源的过滤器解决了我的问题。然后我更改代码。
<resources>
<resource>
<directory>src/main/resources/foo</directory>
<filtering>true</filtering>
<excludes>
<exclude>**/key/*</exclude>
</excludes>
</resource>
<resource>
<directory>src/main/resources/foo/key</directory>
</resource>
</resources>
String keyDerPath = getClass().getResource(privateKeyFileDerPath).getFile();
String AESKeyPathResource = getClass().getResource(AESKeyPath).getFile();
aESKeyFile = new File(AESKeyPathResource );
privateKeyFile = new File(keyDerPath );
