我正在使用struts2-jquery-grid-3.7.0插件尝试使用Struts jQuery 网格进行CRUD 操作,如showcase Grid (Editable/Multiselect) 上所示。

这是表格:

<s:form namespace="/admin_side" action="Test" validate="true" id="dataForm" name="dataForm">
    <s:url id="remoteurl" action="TestGrid" namespace="/admin_side"/>
    <s:url id="editurl" action="EditTest"/>
    <sjg:grid
        id="gridmultitable"
        caption="Example (Editable/Multiselect)"
        dataType="json"
        href="%{remoteurl}"
        pager="true"
        navigator="true"
        navigatorSearchOptions="{sopt:['eq','ne','lt','gt']}"
        navigatorEdit="true"
        navigatorView="true"
        navigatorAddOptions="{height:280, width:500, reloadAfterSubmit:true}"
        navigatorEditOptions="{height:280, width:500, reloadAfterSubmit:false}"                
        navigatorViewOptions="{height:280, width:500}"
        navigatorDelete="true"
        navigatorDeleteOptions="{height:280, width:500,reloadAfterSubmit:true}"
        gridModel="gridModel"
        rowList="5,10,15"
        rowNum="5"
        rownumbers="true"                
        editurl="%{editurl}"
        editinline="true"
        multiselect="true"
        onSelectRowTopics="rowselect">

        <sjg:gridColumn name="countryId" index="countryId" title="Id" formatter="integer" editable="false" dataType="Long" sortable="true" search="true" sorttype="integer" searchoptions="{sopt:['eq','ne','lt','gt']}"/>
        <sjg:gridColumn name="countryName" index="countryName" title="Country Name" editable="true" sortable="true" search="true" sorttype="text"/>
        <sjg:gridColumn name="countryCode" index="countryCode" title="Country Code" sortable="true" search="true" editable="true" sorttype="text"/>

    </sjg:grid>
</s:form>

映射相应动作类中的一个方法,调用该方法,同时执行行的添加、删除和编辑等操作。

@Namespace("/admin_side")
@ResultPath("/WEB-INF/content")
@ParentPackage(value = "json-package")
@InterceptorRefs(
    @InterceptorRef(value = "store", params = {"operationMode", "AUTOMATIC"}))
public final class TestAction extends ActionSupport implements Serializable, ModelDriven<Country>
{
    @Autowired
    private final transient CountryService countryService=null;
    private static final long serialVersionUID = 1L;

    private Country entity=new Country();
    private List<Country> gridModel=new ArrayList<Country>();

    private String oper; //Getter and setter.

    @Action(value = "EditTest",
    results = {
        @Result(name = ActionSupport.SUCCESS, location = "Test.jsp"),
        @Result(name = ActionSupport.INPUT, location = "Test.jsp")},
    interceptorRefs = {
        @InterceptorRef(value = "defaultStack", params = {"validation.validateAnnotatedMethodOnly", "true", "validation.excludeMethods", "load"})})
    public String edit() throws Exception {
        System.out.println(entity.getCountryId()+" : "+entity.getCountryName()+" : "+entity.getCountryCode()+" : "+oper);

        if(oper.equalsIgnoreCase("add")) {
             //Adding a row.   
        }
        else if(oper.equalsIgnoreCase("edit")) {
             //Editing/updating a row. 
        }
        else if(oper.equalsIgnoreCase("del")) {
             //Deleting a row.
        }
        return ActionSupport.SUCCESS;
    }

    @Override
    public Country getModel() {
        return entity;
    }

    @Action(value = "Test",
    results = {
        @Result(name = ActionSupport.SUCCESS, location = "Test.jsp"),
        @Result(name = ActionSupport.INPUT, location = "Test.jsp")},
    interceptorRefs = {
        @InterceptorRef(value = "defaultStack", params = {"validation.validateAnnotatedMethodOnly", "true", "validation.excludeMethods", "load"})})
    public String load() throws Exception {
        //This method is required to return an initial view on page load. Nothing to see here. Leave  it empty.
        return ActionSupport.SUCCESS;
    }
}

删除时,ID(在本例中countryId为 )始终为null

编辑时,countryId为空,因为我设置editable="false"为网格的相应列。当它设置为 时true,它会被检索,但由于它是countryId数据库中的主键,因此不应对其进行编辑。

删除和编辑时如何获取此ID(编辑时不应编辑)?

这不再特别相关ModelDriven


编辑:

在编辑和删除id操作类中的字符串类型字段时,例如,

private String id;

public String getId() {
    return id;
}

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

被初始化为相关网格的行 ID(选定行的)。

在删除多行时,将其初始化为由选定 ID 组成的逗号分隔字符串。

基于网格的行 ID 执行操作是不可靠的。它们应该基于数据库中的主键值来完成。这可能吗?

默认情况下,网格使用id实体的字段(如果有)作为行的唯一键。但是,如果您的实体没有这样的名称,您可以使用key网格列标记的属性将列名称指定为键,该键用于在应用编辑或删除操作时传递给操作。例如

<sjg:gridColumn name="countryId"
                index="countryId"
                title="Id"
                formatter="integer"
                editable="false"
                dataType="Long"
                key="true"
                sortable="true"
                search="true"
                sorttype="integer"
                searchoptions="{sopt:['eq','ne','lt','gt']}"/>

countryId用作表中行的键值,并且该值将在操作期间填充。

就放

loadonce="true"

和搜索操作工作。
