Openxava根據登錄用戶篩選數據

Question

作爲上述標題，我希望僅從登錄用戶獲取分離的數據。例如，同時或不同時，user1加載他/她自己的數據，而user2加載他/她自己的數據，這兩個用戶不共享相同的數據輸出。

Answer 1

下面的代碼是獲取url參數值和過濾用戶數據的解決方案。

Activity.java

... 

    @Hidden 
    @ReadOnly 
    @OnChange(GetParameterValueAction.class) 
    @Column(name="AKA_LOC_ID", length=10) 
    private String locId; 

    ... 

    Getters and Setters 

GetParameterValueAction.java

... 

public class GetParameterValueAction extends OnChangePropertyBaseAction { 

    @Override 
    public void execute() throws Exception { 

     String locId = getRequest().getParameter("LocId"); 

     getView().setValue("locId", locId); 

    } 

} 

OnEachRequestFilteredTabAction.java

... 

public class OnEachRequestFilteredTabAction extends BaseAction{ 

    @Inject @Named("application_locId") 
    private String locId; 

    @Inject 
    private Tab tab; 

    @Override 
    public void execute() throws Exception { 
     locId = getRequest().getParameter("LocId"); 
     if (!Is.empty(locId)) tab.setBaseCondition("${locId}='" + locId + "'"); 
     else tab.setBaseCondition("${locId}='ERROR'"); 
    } 

    public String getLocId() { 
     return locId; 
    } 

    public void setLocId(String locId) { 
     this.locId = locId; 
    } 

    public Tab getTab() { 
     return tab; 
    } 

    public void setTab(Tab tab) { 
     this.tab = tab; 
    } 



    }
