我正在尝试使用jackson库objectmapper计算json字符串。我在pom.xml文件中添加了具有相同版本的jackson注解、jackson databind和jackson core依赖项。但是代码给出了以下错误。我检查了类似的问题,但没有版本不匹配。
Exception in thread "main" java.lang.NoClassDefFoundError: com/fasterxml/jackson/annotation/JsonView

我的代码如下:
try{
ObjectMapper objectMapper=new ObjectMapper();
String jString=objectMapper.writeValueAsString(requestMap);
JsonNode jsonNode=objectMapper.readTree(jString);
System.out.println("From jsonNode:"+jsonNode.get("name"));
}catch (JsonGenerationException e){
e.printStackTrace();
}catch (JsonMappingException e){
e.printStackTrace();
}catch (IOException e){
e.printStackTrace();
}

你能试着把这个添加到pom.xml吗
