** 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 <T> Map<String, Object> beanToMap(T bean) {
           Map<String, Object> 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;
       }
    
    }
