15.3.3. JSON

JSON 攔截器

			
	<action name="withdraw" class="cn.netkiller.api.action.Report" method="getHistory">
		<interceptor-ref name="defaultStack" />
		<interceptor-ref name="json">
			<param name="enableSMD">true</param>

15.3.3.1. enableGZIP 壓縮傳輸

				
		<result name="success" type="json">
			<param name="enableGZIP">true</param>
		</result>

15.3.3.2. excludeProperties 排除 Properties

				
		<result name="success" type="json">
			<param name="excludeProperties">.*direction</param>
		</result>

15.3.3.3.

15.3.4. 傳遞 Timestamp 變數

Struts 從URL傳遞 Timestamp 類型的變數 StartDate

			
http://www.netkiller.cn/api/report/history.do?LoginName=888666&StartDate=2016-01-01&EndDate=2016-02-29

解決方法參考 setStartDate / setEndDate 兩個方法，以字元串方式傳入，然後轉換為Timestamp類型

			
package cn.netkiller.api.action;

import java.sql.Timestamp;
import java.util.Calendar;
import org.apache.struts2.json.annotations.JSON;
import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionSupport;
			
public class Report extends ActionSupport {
	private static final long serialVersionUID = 6484202866632836225L;

	private String loginName;
	private Timestamp startDate = null;
	private Timestamp endDate = null;

	public Report() {

	}

	public String execute() {
		return Action.SUCCESS;
	}

	public String getLoginName() {
		return loginName;
	}

	public void setLoginName(String loginName) {
		this.loginName = loginName;
	}

	public Timestamp getStartDate() {
		return startDate;
	}

	public void setStartDate(String startDate) {
		this.startDate = Timestamp.valueOf(startDate + " 00:00:00");
	}

	public Timestamp getEndDate() {
		return endDate;
	}

	public void setEndDate(String endDate) {
		this.endDate = Timestamp.valueOf(endDate + " 00:00:00");
	}
	
}
