错误：包 io.jsonwebtoken.impl.compression 不存在

Question

当我将

jsonwebtoken

依赖项升级到版本

0.12.5

时，我开始收到以下错误 知道如何解决这个问题吗？

错误：

package io.jsonwebtoken.impl.compression does not exist

。

这是我的 Maven 依赖项：

 <dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt-api</artifactId>
    <version>0.12.5</version>
</dependency>
<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt-impl</artifactId>
    <version>0.12.5</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt-jackson</artifactId>
    <version>0.12.5</version>
    <scope>runtime</scope>
</dependency>

Java 导入：

import io.jsonwebtoken.impl.compression.GzipCompressionCodec;

Answer 1

从

'io.jsonwebtoken:jjwt-impl:0.12.0'

开始，Gzip压缩编解码器已被删除。

相反，引入了类似的类 GzipCompressionAlgorithm。

您可以在以下链接找到更多详细信息。

package io.jsonwebtoken.impl.compression;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

/**

 */
public class GzipCompressionAlgorithm extends AbstractCompressionAlgorithm {

    private static final String ID = "GZIP";

    public GzipCompressionAlgorithm() {
        super(ID);
    }

    @Override
    protected OutputStream doCompress(OutputStream out) throws IOException {
        return new GZIPOutputStream(out);
    }

    @Override
    protected InputStream doDecompress(InputStream is) throws IOException {
        return new GZIPInputStream(is);
    }
}

如果您想使用GzipCompressionCodec，您需要使用0.11.5或更早版本的io.jsonwebtoken。
