SpringMVC如何绑定多选选项元素

Question

我有四个选择选项列表两个用数据库填充数据，两个是多选择绑定到POJO。然后我使用java脚本将数据库选择选项列表中的选项添加到绑定选择选项列表中，但是当我提交给控制器时，如果返回表单有错误并且选择选项列表中包含数据，则数据将丢失。

如果验证发现任何错误，只有当表单发布到控制器时，列表项才能正确获取数据，如果这些字段的数据丢失，则返回表单。

我可能要为类中的列表项编写一个CustomCollectionEditor，如何才能完成？

Crime.java

public class Crime {

    private int crimeRecNo;
    private String crimeDetails;
    private double crimeLatLocation;
    private double crimeLongLocation;
    private String crimeStreetLn1;
    private String crimeStreetLn2;
    private Date crimeDate;
    private String crimeTime;
    private List<Citizens> victims;
    private List<Citizens> criminals;   
    private String recordedById;

//setters and getters

JSP：

<ol>
<li><label>Victims List</label><button id="addVictimBtn">+/button>

<form:select path="" id="dbvictims" title="Victims Of Crime" class="victimLst">
<form:options items="${dbvictims.dbvictimList}" itemValue="socialSecurityNumber" itemLabel="name"/>
</form:select>                      

<label>Victims In Crime</label><button id="removeVictimBtn">-</button> 
<form:select path="victims" id="victims" title="Victims Of Crime"  multiple="multiple" class="victimLst">
<form:options items="${victims.victimList}" itemValue="socialSecurityNumber" itemLabel="name"/>
</form:select><form:errors path="victims" class="errors" />                            
</li>
</ol>                           

<ol>
<li>
<label>Criminals List</label><button id="addCriminalBtn">+</button>
<form:select path="" id="dbcriminals" title="Criminals Of Crime" class="criminalsLst">
<form:options items="${dbcriminals.dbcriminalList}" itemValue="socialSecurityNumber" itemLabel="name"/>
</form:select>  

<label>Criminals In Crime</label><button id="removeCriminalBtn">-</button> 
<form:select path="criminals" id="criminals" title="Criminals Of Crime"  multiple="multiple" class="criminalsLst">
<form:options items="${criminals.criminalList}" itemValue="socialSecurityNumber" itemLabel="name"/>
</form:select><form:errors path="criminals" class="errors" />                           
</li>
</ol>

Jquery的 这用于将dblist中的项添加到from绑定列表元素

    $('#addVictimBtn').click(function(event){
        event.preventDefault();
        var victimId = $('#dbvictims option:selected').val();
        var victimName = $('#dbvictims option:selected').text();
        var options = '<option value="'+ victimId +'">' + victimName +'</option>';
        var exists = false;

    $('#victims option').each(function(){
        //alert($(this).val());
        if(this.value == victimId){

            exists = true;
        }                               
    });         

    if(!exists){
        $('#victims').append(options);              
    }           
    return false;           
});


$('#addCriminalBtn').click(function(event){
    event.preventDefault();
    var criminalId = $('#dbcriminals option:selected').val();
    var criminalName = $('#dbcriminals option:selected').text();
    var options = '<option value="'+ criminalId +'">' + criminalName +'</option>';
    var exists = false;

    $('#criminals option').each(function(){
        //alert($(this).val());
        if(this.value == criminalId){

            exists = true;
        }                               
    });         

    if(!exists){
        $('#criminals').append(options);            
    }           
    return false;           
});

验证

try{
   if(crime.getCriminals().isEmpty()){
    errors.rejectValue("criminals", "criminals.required");
   }                    

}catch(Exception e){
     errors.rejectValue("criminals", "criminals.required");
}


try{
   if(crime.getVictims().isEmpty()){
    errors.rejectValue("victims", "victims.required");
   }
}catch(Exception e){
    errors.rejectValue("victims", "victims.required");
}

错误

在多列表中如果我选择选项然后发布表单我收到以下错误消息

无法将类型为java.lang.String []的属性值转换为属性受害者所需的java.util.List类型;嵌套异常是java.lang.IllegalStateException：无法将类型[java.lang.String]的值转换为属性受害者[0]所需的类型[com.crimetrack.business.Citizens]：找不到匹配的编辑器或转换策略 无效的受害者名单
