java - NoSuchMethodError org.bouncycaSTLe.asn1.ASN1InputStream.readObject()Lorg/bouncycaSTLe/asn1/ASN1Primitive

Question

我在线程“主”java.lang.NoSuchMethodError 中遇到异常: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，你能帮帮我吗，我在这个问题上被困了大约一个星期？

我从这个 Exemple 复制了代码

Answer 1

您为这个版本的 iText 使用了错误版本的 BouncyCaSTLe。

我建议您结合使用 iText 5.5.11 和 BouncyCaSTLe 1.49，如您在 iText POM 中所见: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>

还要确保您只有一个版本的 BouncyCaSTLe。
