Spring-data-jpa 之Specification in的用法

 构建简单的Predicate示例：

            Predicate p1=cb.like(root.get(“name”).as(String.class), “%”+uqm.getName()+“%”);

            Predicate p2=cb.equal(root.get("uuid").as(Integer.class), uqm.getUuid());

            Predicate p3=cb.gt(root.get("age").as(Integer.class), uqm.getAge());

        构建组合的Predicate示例：

           Predicate p = cb.and(p3,cb.or(p1,p2)); 

//根据竞买人客户名称进行查询
            In<Long> in = cb.in(root.get(BailPay_.customerId));
            
            if(customerName != null && !customerName.isEmpty()){
                List<Customer> customerList = customerRepository.findAllByCustomerName(customerName);
                if (customerList != null && customerList.size()>0) {
                    for (Customer customer : customerList) {
                        if (customer != null) {
                            in.value(customer.id());
                        }
                    }
                    predicates.add(in);
                }else{
                    Predicate predicateCustomerId = cb.equal(root.get(BailPay_.customerId), 0L);
                    predicates.add(predicateCustomerId);
                }
            }
