Question

我在线程＆＃34;主要＆＃34;中获得了异常。 java.lang.NoSuchMethodError：org.bouncycastle.asn1.ASN1InputStream.readObject（）Lorg / bouncycastle / asn1 / ASN1Primitive;

这是我的TestSign.java

我已经尝试了所有版本的bcprov-jdk15on和bcmail-jdk15on，你能帮助我吗，我在这个问题上被困了一个星期？

我已经复制了此Exemple

中的代码

Answer 1

您在此版本的iText中使用了错误版本的BouncyCastle。

我建议您使用iText 5.5.11和BouncyCastle 1.49的组合，如iText POM中所示：https://github.com/itext/itextpdf/blob/5.5.11/itext/pom.xml

  <artifactId>itextpdf</artifactId>
  <version>5.5.11</version>

  <dependencies>
    <dependency>
      <groupId>org.bouncycastle</groupId>
      <artifactId>bcprov-jdk15on</artifactId>
      <version>1.49</version>
      <optional>true</optional>
    </dependency>
    <dependency>
      <groupId>org.bouncycastle</groupId>
      <artifactId>bcpkix-jdk15on</artifactId>
      <version>1.49</version>
      <optional>true</optional>
    </dependency>
  </dependencies>

另外请确保您只有一个版本的BouncyCastle。
