查询评论表 而评论表和商品表是多对一的关系，商品表和分类表.地区表多对一的关系，
死循环原因：json无法对comments表的goods属性进行转换
解决办法：
在comments实体类上加注解@JsonIgnoreProperties(value={"goods"})
@JsonIgnoreProperties(value={"goods"})
public class Comments implements java.io.Serializable {
// Fields
/**
*
*/
private static final long serialVersionUID = 6666646538881797793L;
private Integer commentid;
private Goods goods;
private User user;
private String comment;
private String time;
