Spring Data Sql IN 用法

	
	@Override
	public List<Creditinfo> findByMultiAndPage(final String[] orgacode,final String timeStart, final String timeEnd) {
		List<Creditinfo> CreditinfoList = creditinfoDao.findAll(
				new Specification<Creditinfo>() {
					@Override
					public Predicate toPredicate(Root<Creditinfo> root,
							CriteriaQuery<?> query, CriteriaBuilder cb) {
						// TODO Auto-generated method stub
						Predicate predicate = cb.conjunction();
						List<Expression<Boolean>> expressions = predicate
								.getExpressions();

//						if (StringUtils.isNotBlank(creditinfo.getCreditcode())) {
//							expressions.add(cb.equal(root.<String> get("creditcode"),creditinfo.getCreditcode())); // 机构信用代码
//						}
						if (orgacode!=null&&orgacode.length>0) {
							expressions.add(cb.and(root.<String>get("orgacode").in(orgacode))); // 机构信用代码
						}
				
						if (StringUtils.isNotBlank(timeStart)||StringUtils.isNotBlank(timeEnd)) {
							expressions.add(cb.between(root.<String> get("inputdate"),timeStart,timeEnd)); // 机构信用代码
						}
						
						
						return predicate;
					}
				});

 总结，方法要学会变通……
