Openxava：將Url參數保存到會話對象

Question

我使用會話來保存url參數year（例如。http://localhost:8080/CkSurvey/m/Sport?Year=2016）。我已經爲會話編寫了所有代碼，但它僅適用於上載圖像之前的第一個條目。更改url後，會話對象holded無法檢索和加載。

這裏是我的嘗試：

Sport.java

package org.survey.model; 

import java.math.*; 
import java.util.*; 
import javax.persistence.*; 
import org.openxava.annotations.*; 
import org.openxava.calculators.*; 
import org.survey.actions.*; 
import org.survey.calculators.*; 

@Table(name="T_SPORT") 

@View(members= "title; date; estimatedCost; attendance; remark; image; year") 

@Entity 
public class Youth { 

    //******************************FORM ID******************************// 
    @Id 
    @Hidden 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    @Column(name="YOUTH_ID", length=10, unique = true, nullable = false, updatable = false) 
    private int youthId; 

    //******************************TYPE/CATEGORY*** 
    //******************************TITLE******************************// 
    @Column(name="YOUTH_TITLE", precision=2000) 
    @Required 
    private String title; 

    //******************************DATE******************************// 
    // @Stereotype("DATE") 
    @Column(name="YOUTH_DATE") 
    @Required 
    private Date date; 

    //******************************ESTIMATED COST******************************// 
    @Hidden 
    @Stereotype("MONEY") 
    @Column(name="YOUTH_EST_COST") 
    @Required 
    private BigDecimal estimatedCost; // Include the import java.math.* BigDecimal is typically used for money 

    //******************************ESTIMATED ATTENDEES******************************// 
    @Hidden 
    @Column(name="YOUTH_ATTENDANCE", length=10) 
    @Required 
    private int attendance; 

    //******************************REMARK******************************// 
    @Hidden 
    @Editor("TextAreaNoFrame") 
    @Stereotype("MEMO") 
    @Column(name="YOUTH_REMARK", precision=2000) 
    private String remark; 

    @Stereotype("PHOTO") 
    @Column(name="YOUTH_IMAGE") 
    private byte [] image; 

    //******************************URL PARAMETER (Year)******************************// 
    //@Hidden 
    @ReadOnly 
    //@DefaultValueCalculator(YearCalculator.class) 
    //@OnChange(GetParameterValueAction.class) 
    @Column(name="YOUTH_YEAR", length=4) 
    private String year; 

    //******************************GETTERS AND SETTERS FOR ALL PROPERTIES******************************// 

    public int getYouthId() { 
     return youthId; 
    } 

    public void setYouthId(int youthId) { 
     this.youthId = youthId; 
    } 

    public String getTitle() { 
     return title; 
    } 

    public void setTitle(String title) { 
     this.title = title; 
    } 

    public Date getDate() { 
     return date; 
    } 

    public void setDate(Date date) { 
     this.date = date; 
    } 

    public BigDecimal getEstimatedCost() { 
     return estimatedCost; 
    } 

    public void setEstimatedCost(BigDecimal estimatedCost) { 
     this.estimatedCost = estimatedCost; 
    } 

    public int getAttendance() { 
     return attendance; 
    } 

    public void setAttendance(int attendance) { 
     this.attendance = attendance; 
    } 

    public String getRemark() { 
     return remark; 
    } 

    public void setRemark(String remark) { 
     this.remark = remark; 
    } 

    public String getYear() { 
     return year; 
    } 

    public void setYear(String year) { 
     this.year = year; 
    } 

    public byte[] getImage() { 
     return image; 
    } 

    public void setImage(byte[] image) { 
     this.image = image; 
    } 

} 

SessionUrlParamsAction.java

package org.survey.actions; 

import javax.inject.*; 

import org.openxava.actions.*; 

public class SessionUrlParamsAction extends SaveAction { 

    @Inject @Named("CkSurveysessionYear") 
    private String sessionYear; 

    private String uid; 

    @Override 
    public void execute() throws Exception { 

     sessionYear = getRequest().getParameter("Year"); 

     getView().setValue("year", sessionYear); 

     super.execute(); 

     System.out.println("year============" + sessionYear); 

    } 

} 

controllers.xml（動作）

<action name="save" mode="detail" 
      by-default="if-possible" 
      class="org.survey.actions.SessionUrlParamsAction" 
      image="save.gif" 
      icon="content-save" 
      on-init="true" 
      keystroke="Control S"/> 

什麼樣的變化，我應該對蘇有效握住並檢索會話對象？

問題通過添加initAction和saveAction解決。 initAction獲取url參數值，而saveAction將值設置爲各自的屬性字段。
