更新JSON：
如果您可以控制JSON数据，确保只包含已知的字段，或者更新JSON结构以匹配MainLeadsDTO类的预期格式。
忽略未知字段：
如果您希望在JSON解析过程中忽略未知字段，可以配置Jackson ObjectMapper来忽略未知属性。您可以在MainLeadsDTO类上添加@JsonIgnoreProperties(ignoreUnknown = true)注解，或者直接配置ObjectMapper。
修改类定义：
如果"imPremodelCode"字段确实是应该包含在MainLeadsDTO类中的有效字段，您需要在类定义中添加相应的属性。确保属性名称与字段名称完全匹配，并考虑添加任何必要的注解或getter/setter方法。
