struts2 action如何接收页面传来的布尔值

action:public class ClazzAction {
        /**
     * 是否删除 
     */
    private Boolean deleted;
    public Boolean getDeleted() {
        return deleted;
    }    public void setDeleted(Boolean deleted) {
        this.deleted = deleted;
    }
}
部分jsp:
 <s:select name="deleted" list="#{'false':'正常','true':'已删除'}" listKey="key" listValue="value"/>
