Java8中List的removeif()函数的使用示例

代码：

import java.util.List;
import java.util.function.Predicate;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import com.anbank.eva.po.RptEbankMerchantDetail;
import com.anbank.eva.service.RptEbankMerchantDetailService;

@RestController
@RequestMapping("/RPT_EBANK_MERCHANT_DETAIL")
public class RptEbankMerchantDetailController {

	@Autowired
    private RptEbankMerchantDetailService rptEbankMerchantDetailService;
	
    @RequestMapping("/all")
    public List<RptEbankMerchantDetail> getAllRptEbankMerchantDetails() {
        List<RptEbankMerchantDetail> list = this.rptEbankMerchantDetailService.getAllRptEbankMerchantDetails();
        return list;
    }
    
    @RequestMapping("/result")
    public List<RptEbankMerchantDetail> getRptEbankMerchantDetails(@RequestParam(value="orgId", required=false)  String orgId,
															    		@RequestParam(value="startDate", required=false) String startDate,
																	    @RequestParam(value="endDate", required=false) String endDate,
																	    @RequestParam(value="merId", required=false) String merId
    										) {
    	List<RptEbankMerchantDetail> list = this.rptEbankMerchantDetailService.getAllRptEbankMerchantDetails();
    	Predicate<RptEbankMerchantDetail> predicate = (ele) -> {
    		if (orgId != null && orgId.equals(ele.getORG_CODE()) == false)
    			return true;
			if (startDate != null && startDate.compareTo(ele.getCREATE_DT()) > 0)
				return true;
			if (endDate != null && endDate.compareTo(ele.getCREATE_DT()) < 0)
				return true;
			if (merId != null && merId.equals(ele.getMER_ID()) == false)
				return true;
			return false;
    	};
    	list.removeIf(predicate);
    	return list;
    }
}
