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());
      }
  }

但我得到以下例外：

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)

我想这是因为杰克逊并不知道它应该用于哪个二传手？＃34; matchColumn＆＃34; （其中有4个）。但我不知道为什么它甚至试图设置这个领域，因为我没有宣布任何＆＃34; matchColumn＆＃34; JSON中的属性...... 有什么想法吗？

问题解决了：我使用的是旧版杰克逊。 2.7版本适用于我
