数据库中是以int形式存储,页面需要显示其对应信息的方法(例如性别,状态)

此处以班级状态为例:

班级实体:

public class Team {
	public static final Integer STATE_NOTBEGIN = 1;
	public static final String STATE_NOTBEGIN_VIEW = "未开课";
	public static final Integer STATE_BEGIN = 2;
	public static final String STATE_BEGIN_VIEW = "已开课";
	public static final Integer STATE_FINISH = 3;
	public static final String STATE_FINISH_VIEW = "已结课";
	
	private Integer id;
	private String tname;
	private Integer state;//0无效,1未开课,2已开课,3已结课,默认1

	//提供对应map集合用于下拉框或单选框显示
	public static final Map<Integer,String> stateMap = new HashMap<Integer,String>(3);
	static{
		stateMap.put(STATE_NOTBEGIN, STATE_NOTBEGIN_VIEW);
		stateMap.put(STATE_BEGIN, STATE_BEGIN_VIEW);
		stateMap.put(STATE_FINISH, STATE_FINISH_VIEW);
	}

	//提供状态显示get方法
	public String getStateView(){
		String stateView = null;
		if(this.state == STATE_NOTBEGIN){
			stateView = STATE_NOTBEGIN_VIEW;
		}else if(this.state == STATE_BEGIN){
			stateView = STATE_BEGIN_VIEW;
		}else if(this.state == STATE_FINISH){
			stateView = STATE_FINISH_VIEW;
		}else{
			stateView = "错误状态";
		}
		return stateView;
	}
} 

此处均使用struts标签:

jsp页面显示状态信息:

<s:property value="team.stateView"/>

下拉框与单选框显示:

<s:select name="team.state" list="@cn.xxxxxx.crm.domain.Team@stateMap"/>

<s:radio name="team.state" list="@cn.xxxxxx.crm.domain.Team@stateMap"/>
