1，实体类上加注解

@Builder

2，试用build构造器进行赋值

        // 创建默认分组
        MatchInfoGroupEntity matchInfoGroupEntity = MatchInfoGroupEntity.builder()
                .matchInfoId(dto.getId())
                .groupName("默认分组")
                .matchType(dto.getGroupType())
                .lev(dto.getGroupLev())
                .matchPeople(dto.getMatchPeople())
                .build();
