bboss mvc忽略对bean属性进行参数绑定方法

bboss mvc忽略对bean属性进行参数绑定方法非常简单，通过在bean的属性上添加@IgnoreBind注解即可，参考示例如下：

import org.frameworkset.util.annotations.IgnoreBind;
public class ExampleBean
{
	@IgnoreBind
	private String name = null;

	
	public String getName()
	{
	
		return name;
	}

	
	public void setName(String name)
	{
	
		this.name = name;
	}

}

@IgnoreBind另外的一个作用：如果对象存在自引用关系，可以用来防止mvc参数绑定时出现死循环导致堆栈溢出的问题，例如对象结构为：

public class UserBusinessBean {

    private String id;// 主键id

    private String userId;// 用户id

    private String userRealname;// 用户名称

    private String modelId;// 设备型号id

    private String equipmentModel;// 设备型号

    private String geographicalPosition;// 地理位置

    private String faultId;// 故障部位id

    private String faultPosition;// 故障部位

    @IgnoreBind
    private List<UserBusinessBean> businessList;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public String getModelId() {
        return modelId;
    }

    public void setModelId(String modelId) {
        this.modelId = modelId;
    }

    public String getGeographicalPosition() {
        return geographicalPosition;
    }

    public void setGeographicalPosition(String geographicalPosition) {
        this.geographicalPosition = geographicalPosition;
    }

    public String getFaultId() {
        return faultId;
    }

    public void setFaultId(String faultId) {
        this.faultId = faultId;
    }

    public String getEquipmentModel() {
        return equipmentModel;
    }

    public void setEquipmentModel(String equipmentModel) {
        this.equipmentModel = equipmentModel;
    }

    public String getFaultPosition() {
        return faultPosition;
    }

    public void setFaultPosition(String faultPosition) {
        this.faultPosition = faultPosition;
    }

    public String getUserRealname() {
        return userRealname;
    }

    public void setUserRealname(String userRealname) {
        this.userRealname = userRealname;
    }

    
    public List<UserBusinessBean> getBusinessList() {
        return businessList;
    }

    
    public void setBusinessList(List<UserBusinessBean> businessList) {
        this.businessList = businessList;
    }


}

UserBusinessBean对象中定义了以下属性businessList：
@IgnoreBind
    private List<UserBusinessBean> businessList;
如果不加 @IgnoreBind注解，那么mvc在绑定UserBusinessBean类型的参数时，就导致堆栈溢出，加上就没问题，以下是可能出现的堆栈溢出错误信息以供参考：
