 错误代码

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

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

对象转Map函数

public class FunctionUtils {
	
	public static  Map beanToMap(T bean) {
       Map map = new HashMap<>();
       if (bean != null) {
           BeanMap beanMap = BeanMap.create(bean);
           for (Object key : beanMap.keySet()) {
               if(beanMap.get(key) != null)
                   map.put(key + "", beanMap.get(key));
           }
       }
       return map;
   }

}
