错误代码

  1. IndexRequest ir=new IndexRequest(EsIndexs.NBA_LATEST).id(id).source(nbaPlayer);

nbaPlayer对象不能直接传输需要转成Map

正确代码

  1. IndexRequest ir=new IndexRequest(EsIndexs.NBA_LATEST).id(id).source(FunctionUtils.beanToMap(nbaPlayer));

对象转Map函数

  1. public class FunctionUtils {
  3.     public static <T> Map<String, Object> beanToMap(T bean) {
  4.        Map<String, Object> map = new HashMap<>();
  5.        if (bean != null) {
  6.            BeanMap beanMap = BeanMap.create(bean);
  7.            for (Object key : beanMap.keySet()) {
  8.                if(beanMap.get(key) != null)
  9.                    map.put(key + "", beanMap.get(key));
  10.            }
  11.        }
  12.        return map;
  13.    }
  15. }
