spring注入web端校验类

首先这是针对于SPRING3.0的例子（注解）；再次也是批量校验的方式：
1.配置好附件内容
2.validate类：

package com.guohualife.rcms.riskGrade.web.controller.validate;

import java.util.List;

import org.apache.commons.lang.StringUtils;
import org.springframework.stereotype.Component;

import com.guohualife.rcms.common.api.utils.CheckValidate;
import com.guohualife.rcms.common.web.validate.Errors;
import com.guohualife.rcms.common.web.validate.WebValidator;
import com.guohualife.rcms.common.web.validate.rule.NullableRule;
import com.guohualife.rcms.common.web.validate.rule.StringLengthRule;
import com.guohualife.rcms.riskGrade.api.util.ConstantEnum;
import com.guohualife.rcms.riskGrade.dto.GradeIndexPropertyDTO;
import com.guohualife.rcms.riskGrade.dto.QualitativeRuleDTO;

@Component("gradeRuleValidate")
public class GradeRuleValidate extends WebValidator {

	@SuppressWarnings("unchecked")
	@Override
	protected void baseValidate() {
		NullableRule nullableRule = null;// 基础校验:非空
		StringLengthRule stringLengthRule = null;// 基础校验:长度
	}

	@Override
	protected void validate(Object obj, Errors errors) {
		GradeIndexPropertyDTO gradeIndexPropertyDTO = (GradeIndexPropertyDTO) obj;
		String gradeIndexType = gradeIndexPropertyDTO.getGradeIndexType();

		if (StringUtils.equals(gradeIndexType, ConstantEnum.GRADE_INDEX_TYPE_DL)) {
			List salechnlList = gradeIndexPropertyDTO.getSalechnlList();
			for (int i = 0; i < salechnlList.size(); i++) {
				
			}

		} else if (StringUtils.equals(gradeIndexType, ConstantEnum.GRADE_INDEX_TYPE_DX)) {
			String gradeScore= gradeIndexPropertyDTO.getGradeScore();
			double gradeScoreDou = 0 ;
			if(StringUtils.isNotEmpty(gradeScore)){
				gradeScoreDou =Double.parseDouble(gradeScore);				
			}
			List qualitativeRuleList = gradeIndexPropertyDTO.getQualitativeRuleList();

			double allQuestItemScore = 0 ;
			double eqQualitativeScore = 0;
			
			String eqQuestionBankId ="";
			/*====begin 计算题目总分之和的参数====*/
			double allQualitativeScore = 0;
			/*====end 计算题目总分之和的参数====*/		
			for (int i = 0; i < qualitativeRuleList.size(); i++) {			
				boolean checkOneFlag  = false;
				boolean checkTwoFlag = false;
				QualitativeRuleDTO qualitativeRuleDTO = (QualitativeRuleDTO) qualitativeRuleList.get(i);
				String rowSpan = qualitativeRuleDTO.getOptionNum();
				String qualitativeScore = qualitativeRuleDTO.getQualitativeScore();
				boolean  checkIsNotNullFlag = this.checkIsNotNullMethod(errors, qualitativeRuleDTO, i);
				String questionBankId = qualitativeRuleDTO.getQuestionBankId();
				if(!checkIsNotNullFlag){
					//校验业务逻辑
					String qualitativeScoreObj ="";
					double qualitativeScoreDou =0;
					double questItemScoreDou = 0 ;
					if (StringUtils.isNotEmpty(rowSpan)) {
						qualitativeScoreObj = "qualitativeRuleList[" + i + "].qualitativeScore";
						qualitativeScoreDou =Double.parseDouble(qualitativeScore);
						if( qualitativeScoreDou > gradeScoreDou){
							errors.rejectValue(qualitativeScoreObj, "不能大于总分值");
							checkOneFlag  = true;
						}
						eqQuestionBankId = questionBankId;
						if (StringUtils.isNotEmpty(qualitativeScore)) {
							eqQualitativeScore = Double.parseDouble(qualitativeScore);
						}
					}
	
					String questItemScore = qualitativeRuleDTO.getQuestItemScore();
					String questItemScoreObj ="qualitativeRuleList[" + i + "].questItemScore";
	
					questItemScoreDou =Double.parseDouble(questItemScore);
					if( questItemScoreDou > eqQualitativeScore){
						errors.rejectValue(questItemScoreObj, "单条选项不能大于当前题目分值");
						checkOneFlag  = true;
					}
					if(!checkOneFlag){
						/*====begin 计算题目总分之和====*/
						allQualitativeScore = allQualitativeScore + qualitativeScoreDou;
						/*====end 计算题目总分之和====*/
						
						checkTwoFlag = true ;
					}

					
					/*====begin 计算题目选项总分之和====				
					if(StringUtils.equals(eqQuestionBankId , questionBankId)){
						allQuestItemScore = allQuestItemScore + questItemScoreDou;
					}else{
						System.out.println("    题目选项总分="+allQuestItemScore);
						if( allQuestItemScore > eqQualitativeScore){
							errors.rejectValue("qualitativeRuleList[" + (i-1) + "].qualitativeScore", "题目分值不能小于选项分值总和");
						}
						allQuestItemScore =0;
					}
					====end 计算题目选项总分之和====*/	
				}
			}
			//for 循环结束后
			if(allQualitativeScore > gradeScoreDou){
				errors.rejectValue("gradeScore", "不能小于题目分值之和");
			}
			System.out.println("题目总分="+allQualitativeScore);
		}
	}
	
	/**

	private boolean checkIsNotNullMethod(Errors errors,QualitativeRuleDTO qualitativeRuleDTO,int i){

				errors.rejectValue(questItemScoreObj, "只能输入整数或两位小数点");
				checkResult  = true;
			}
		}
		return checkResult;
	}
	
}

3.controller中注入validate校验类：

    @Resource(name = "gradeRuleValidate")
    private Validator validator;
