**1.重写实体类Bean的equals()和hashCode()方法**

package com.wsbs.modules.personal.entity;
    
    import com.ect.cloud.common.persistence.DataEntity;
    
    /**
     * 
     * 此类描述的是：个人基本信息
     */
    public class PersonalBasicListBean extends DataEntity<PersonalBasicListBean>{
    
    	private static final long serialVersionUID = 1L;
    	private String grbh;//个人编号
    	private String dwmc;//单位名称
    	private String sfzh;//身份证号
    	private String xm;//姓名
    	private String xb;//性别
    	private String mz;//民族
    	private String cjgzsj;//参加工作日期
    	private String ryzt;//人员状态
    	private String cbzt;//参保状态
    	private String ssqh;//所属区号
    	private String kh;//社会保障卡卡号
    	private String ltxsj;//离退休日期

    	private String ybcnsj;//医保参保时间
    	private String ybjfys;//医保缴费月数
    	private String ybzhye;//医保账户余额
    	private String ylcnsj;//养老参保时间
    	private String yljfsj;//养老月数
    	private String yljfys;//养老账户总额
    	private String aab324;//统筹区 341801
    
    	@Override //重写equals方法 
    	public boolean equals(Object obj) {  
    	PersonalBasicListBean s=(PersonalBasicListBean)obj;   
    	return grbh.equals(s.grbh) && 
    		   dwmc.equals(s.dwmc) &&

    		   ybcnsj.equals(s.ybcnsj) &&
    		   ybjfys.equals(s.ybjfys) &&
    		   ybzhye.equals(s.ybzhye) &&
    		   ylcnsj.equals(s.ylcnsj) &&
    		   yljfsj.equals(s.yljfsj) &&
    		   yljfys.equals(s.yljfys);   
    	}  
    	
    	@Override  //重写hashCode方法
    	public int hashCode() {  
    	String in = grbh + dwmc + sfzh + xm + xb + mz+

    	public void setAab324(String aab324) {
    		this.aab324 = aab324;
    	}
    
    }

**2.用此bean接收实体类List集合接收数据，用hashSet方法进行去重得到新集合，并对新集合进行测试**

//用list<Bean>接受数据
    List<PersonalBasicListBean> pbList = 
                    personalBasicService.getGrjbxxList(login.getUuid(), login.getAac002(), 
                    login.getAac003(), Global.getConfig("token"));
    //使用hashSet进行对象中元素的去重，获得新对象集合list
    Set<PersonalBasicListBean> ts = new HashSet<PersonalBasicListBean>();  
    ts.addAll(pbList);  
    //循环打印测试
    System.out.println("循环打印出不重复的对象.........");
    for (PersonalBasicListBean pbl : ts) {  
    	ystem.out.println(pbl);  
    } 
    //将去重后的List集合放入视图中
    model.addAttribute("personalBasicBeanList", ts);

**3.在jsp页面上对List<Bean>集合进行长度判断和循环**

<c:forEach items="${personalBasicBeanList}" var="personalBasicBean">
    	        <c:if test="${fn:length(personalBasicBeanList)>1}">
                <span style="font-weight:bold;color:green;font-size:14px"> ${personalBasicBean.xm}</span>
    	        <span style="color:#157ab5;font-size:14px;font-weight:bold">在参保区 </span>
    	        <span style="font-weight:bold;color:green;font-size:14px">${fns:getDictLabel(personalBasicBean.ssqh, "aab324", "")} </span>
    	        <span style="font-weight:bold;color:#157ab5;font-size:14px">的个人基本信息</span>
    	        </c:if>
    	        
    	        <table class="table table-striped table-bordered table-condensed">
