springmvc 处置lsit类型的请求参数

springmvc 处理lsit类型的请求参数

<table align="center"  cellspacing="10">
  				<tr>
  					<td>
  					          母码数目:<input type="text" name="uidCodeGenNumParamList[0].superCodeGenNum"  style="width:180px;" class="textbox" maxlength="24"/>
  					        
  					        子码数目:<input type="text" name="uidCodeGenNumParamList[0].childCodeGenNum" style="width:180px;" class="textbox" maxlength="24" /> 					    
  					</td>
  				</tr>
 				<tr>
  					<td>
  					          母码数目:<input type="text" name="uidCodeGenNumParamList[1].superCodeGenNum"  style="width:180px;" class="textbox" maxlength="24"/>
  					        
  					        子码数目:<input type="text" name="uidCodeGenNumParamList[1].childCodeGenNum" style="width:180px;" class="textbox" maxlength="24" /> 					    
  					</td>
  				</tr>		
  			</table>

这是html页面请求提交到服务器的表单代码,注意文本框的属性name为:

name="uidCodeGenNumParamList[1].superCodeGenNum"

这是在服务端定义的实体:

public class UidCodeGenNumParam extends EntityBase {

	private String superCodeGenNum;
	private String childCodeGenNum;

	public String getSuperCodeGenNum() {
		return superCodeGenNum;
	}

	public void setSuperCodeGenNum(String superCodeGenNum) {
		this.superCodeGenNum = superCodeGenNum;
	}

	public String getChildCodeGenNum() {
		return childCodeGenNum;
	}

	public void setChildCodeGenNum(String childCodeGenNum) {
		this.childCodeGenNum = childCodeGenNum;
	}

}

必须要将这个类型作为list类型的属性包装在 bean 中:

public class UidCodeGenNumParamFormList extends EntityBase {

	private List<UidCodeGenNumParam> uidCodeGenNumParamList;

	public List<UidCodeGenNumParam> getUidCodeGenNumParamList() {
		return uidCodeGenNumParamList;
	}

	public void setUidCodeGenNumParamList(
			List<UidCodeGenNumParam> uidCodeGenNumParamList) {
		this.uidCodeGenNumParamList = uidCodeGenNumParamList;
	}



}

在controller中,获取list参数:

@RequestMapping(value="/add")
	public Object addUidCode(@ModelAttribute UidCodeGenNumParamFormList genNumList,
			HttpServletRequest req,HttpServletResponse resp) throws Exception{
		for(UidCodeGenNumParam genNum:genNumList.getUidCodeGenNumParamList()){
			System.out.println(genNum.getSuperCodeGenNum()+";"+genNum.getChildCodeGenNum());
		}
		Map<String,Object> busResult  = uidCodeBusiness.add(req,genNumList);	  
	    return CommonUtils.controlResult(busResult, resp);
	}
