import com.fasterxml.jackson.annotation.JsonProperty;
import java.util.Set;
公共类MyPojo {
@JsonProperty("name")
private Set<String> names;
@JsonProperty("country")
private String country;
public Set<String> getNames() {
return names;
}
public void setNames(Set<String> names) {
this.names = names;

从json反序列化为Java对象时，出现以下错误：

相反，我尝试导入org.codehaus.jackson.annotate.JsonProperty，现在它可以正常工作且没有错误。一种版本的debian计算机上会发生这种现象。另一台机器，codehaus和fasterxml都可以正常工作！
我无法找到问题的根本原因。请帮忙。
