java.lang.NoClassDefFoundError：使用 Java 11 解码 JWT 令牌时的 javax/xml/bind/DatatypeConverter

Question

When calling this method for decoding a JWT token javax.xml.bind.DatatypeConverter.parseBase64Binary(encoded) I get this exception:

org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter

I have this external libraries on the project among others:

implementation "jakarta.xml.bind:jakarta.xml.bind-api:3.0.1"
  implementation "org.glassfish.jaxb:jaxb-runtime:3.0.2"
  io.jsonwebtoken:jjwt:0.9.1
javax.xml.bind:jaxb-api:2.3.1

In the external library javax.xml.bind:jaxb-api:2.3.1 I can find the javax/xml/bind/DatatypeConverter used in the code so I don't understand why I'm getting the NoClassDefFoundError.

I use Java 11 on the project and spring boot.

Thanks for the help.

Answer 1

Add this line in gradle.

implementation 'javax.xml.bind:jaxb-api:2.4.0-b180830.0359'

Downgrade your javax.xml.bind:jaxb-api With specific version.

Answer 2

Add this class to your program for now until new versions of io.jsonwebtoken that work with jakarta are ready.

The path of this class must be io.jsonwebtoken.impl

package io.jsonwebtoken.impl;

import jakarta.xml.bind.DatatypeConverter;

public class Base64Codec extends AbstractTextCodec {
    public Base64Codec() {
    }

    public String encode(byte[] data) {
        return DatatypeConverter.printBase64Binary(data);
    }

    public byte[] decode(String encoded) {
        return DatatypeConverter.parseBase64Binary(encoded);
    }
}
