java - org.codehaus.jackson.map.JsonMappingException : Conflicting setter definitions for property "matchColumn": com. sun.rowset.JdbcRowSetImpl

Question

我正在使用 Jackson 反序列化 com.sun.rowset.JdbcRowSetImpl 类的对象:

public class Main {

static String jsonInput = "{\"@class\":\"com.sun.rowset.JdbcRowSetImpl\", \"dataSourceName\":\"ldap://localhost:10389/ldap://localhost:10389/cn=apartment16,dc=example,dc=com\", \"autoCommit\":true}";


      public static void main(String[] args) throws Exception{
          ObjectMapper mapper = new ObjectMapper();
          mapper.enableDefaultTyping();
          Object o = mapper.readValue(jsonInput, JdbcRowSetImpl.class);
          System.out.println(o.getClass());
      }
  }

但我遇到以下异常:

Exception in thread "main" org.codehaus.jackson.map.JsonMappingException: Conflicting setter definitions for property "matchColumn": com.sun.rowset.JdbcRowSetImpl#setMatchColumn(1 params) vs com.sun.rowset.JdbcRowSetImpl#setMatchColumn(1 params)

我猜这是因为 Jackson 不知道应该对“matchColumn”字段使用哪个 setter(有 4 个)。但我不知道为什么它甚至尝试设置该字段，因为我没有在 JSON 中声明任何“matchColumn”属性...有什么想法吗？

问题已解决:我使用的是旧版本的 jackson。 2.7 版本对我来说效果很好
