Java 使用JsonSchema验证Json时未发现类异常

我是Java新手

我试图用JsonSchema验证Json。我已经提到。。我尝试了#Tihamer代码，得到了一个JsonParserException，但我没有使用它

下面是我的代码

        try{

            JsonNode dataNode = JsonLoader.fromString(jsonData);
            JsonSchemaFactory factory = JsonSchemaFactory.byDefault();
            JsonSchema schema = factory.getJsonSchema(schemaNode);
            report = schema.validate(dataNode);
        }
        catch(Exception ex){
            ex.printStackTrace();

Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.core.JsonParseException

    ...

它清楚地表明
错误是由包
com.fasterxml.jackson.core
的类
JsonParseException
引起的，JVM试图加载该包，但由于它不在类路径中，因此找不到它

只需在类路径中添加
com.fasterxml.jackson.core
jar文件。
添加jackson-annotations.jar
从下载

如果是maven项目，则添加此依赖性

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>2.6.3</version>
</dependency>


com.fasterxml.jackson.core

对于第二个错误：添加此（替换版本）
下载jar并添加


com.fasterxml.jackson.core
杰克逊核心
${jackson.version}
Thank you@thegauravmahawar..你的回答帮助我解决了这个错误。你能帮我解决我在同一个问题中提到的另一个错误吗？谢谢你…我下载了jar文件并解决了这个错误..谢谢你的帮助检查我的第二次更新error@VedantKekan我的不是maven项目。那么我可以添加depen吗密度？？检查已更新answer@VedantKekan谢谢你，问题解决了，唯一缺少的就是罐子，我把所有的罐子都加了进去，结果出来了。
