스트럿츠 형태의 멀티 액션

Question

스트럿 폼에 3 개의 버튼을 추가하고 싶습니다. 내 코드는 다음과 같습니다 JSP에서

@Action("/admin/product/insert") 
public String insert() throws Exception { 
    if(upload.hasFile()){ 
     model.setImage(upload.getFileFileName()); 
     upload.saveTo("../images/customers/"); 
    } 
    else{ 
     model.setImage("product.png"); 
    } 
    XHibernate.save(model); 
    return "new"; 
} 

@Action("/admin/product/update") 
public String update() throws Exception { 
    if(upload.hasFile()){ 
     model.setImage(upload.getFileFileName()); 
     upload.saveTo("../images/customers/"); 
    } 
    System.out.println("update"); 
    XHibernate.update(model); 
    return "input"; 
} 

@Action("/admin/product/delete") 
public String delete() throws Exception { 
    XHibernate.delete(model); 
    return "new"; 
} 

:

<s:form enctype="multipart/form-data" theme="simple" role="form"> 

    <div class="form-group col-md-4"> 
     <label for="id">Product Id</label> 
     <s:textfield id="productId" name="id" cssClass="form-control" /> 
    </div> 

    <div class="form-group col-md-4"> 
     <label for="name">Product Name</label> 
     <s:textfield name="name" cssClass="form-control" /> 
    </div> 

    <div class="form-group col-md-4"> 
     <label for="unitPrice">Unit Price</label> 
     <s:textfield name="unitPrice" cssClass="form-control" /> 
    </div> 

    <div class="form-group col-md-4"> 
     <label for="unitBrief">Unit Description</label> 
     <s:textfield name="unitBrief" cssClass="form-control" /> 
    </div> 

    <div class="form-group col-md-4"> 
     <label for="discount">Discount</label> 
     <s:textfield name="discount" cssClass="form-control" /> 
    </div> 

    <div class="form-group col-md-4"> 
     <label for="quantity">Quantity</label> 
     <s:textfield name="quantity" cssClass="form-control" /> 
    </div> 

    <div class="form-group col-md-4"> 
     <label for="productDate">Product Date</label> 
     <s:textfield name="productDate" cssClass="form-control" /> 
    </div> 

    <div class="form-group col-md-4"> 
     <label for="supplier.id">Supplier</label> 
     <s:select name="supplier.id" list="suppliers" listKey="id" 
      listValue="name" cssClass="form-control" /> 
    </div> 

    <div class="form-group col-md-4"> 
     <label for="category.id">Category</label> 
     <s:select name="category.id" list="categories" listKey="id" 
      listValue="name" cssClass="form-control" /> 
    </div> 

    <div class="form-group col-md-4"> 
     <label>Features</label> 
     <div> 
      <label><s:checkbox name="available" /> Available</label> <label><s:checkbox 
        name="special" /> Special</label> <label><s:checkbox 
        name="latest" /> latest</label> 
     </div> 
    </div> 

    <div class="form-group col-md-4"> 
     <label for="image">Image</label> <input id="image" type="file" 
      name="upload.file"> 
     <s:hidden name="image" /> 
    </div> 

    <div class="form-group col-md-12"> 
     <label for="description">Description</label> 
     <s:textarea id="index_description" name="description" rows="30" 
      cssClass="form-control" /> 
    </div> 

    <div class="col-md-12"> 
     <s:submit value="Thêm mới" action="admin/product/insert" 
      cssClass="btn btn-default" /> 
     <s:submit value="Cập nhật" action="admin/product/update" 
      cssClass="btn btn-default" /> 
     <s:submit value="Xóa" action="admin/product/delete" cssClass="btn btn-default" /> 
     <a href="product/index" class="btn btn-default">Nhập lại</a> 
    </div> 
</s:form> 

문제는 그것이 정확하게 조치를 호출 할 수있다.

"네임 스페이스/admin/제품 및 작업 이름 admin/product/update에 매핑 된 작업이 없습니다."라는 오류가 항상 나타납니다.

3 가지 형식으로 나누어야합니까? 또는 내 코드처럼 3 개의 동작에 3 개의 버튼이있는 방법이 있습니까? 어떤 도움이라도 좋을 것입니다. DEVMODE를 사용하도록 설정하면

Answer 1

현재 문제를 해결하려면, 당신은 struts.xml에서

<constant name="struts.enable.SlashesInActionNames" value="true"/> 

을 추가해야합니다, 그것은 기본적으로 거짓이며, 소요됩니다 액션 이름 대신 네임 스페이스로 마지막 슬래시 앞에있는 모든 부분. BTW이 부작용이 있습니다

액션

@Namespace("/admin/product") 
public class YourAction extends ActionSupport 

    @Action("insert") 
    public String insert() throws Exception { 
     /* .... */ 
    } 

    @Action("update") 
    public String update() throws Exception { 
     /* .... */ 
    } 

    @Action("delete") 
    public String delete() throws Exception { 
     /* .... */ 
    } 

JSP

:

Action Names With Slashes

If your action names have slashes in them (for example,
<action name="admin/home" class="tutorial.Admin"/>) you need to specifically allow slashes in your action names via a constant in the struts.xml file by specifying

<constant name="struts.enable.SlashesInActionNames" value="true"/> .

See JIRA Issue WW-1383 for discussion as there are side effects to setting this property to true.

문제 올바른 방법를 해결하기를, 당신은 네임 스페이스의 올바른 사용을해야

<s:submit value="Thêm mới" action="insert" cssClass="btn btn-default" /> 
<s:submit value="Cập nhật" action="update" cssClass="btn btn-default" /> 
<s:submit value="Xóa"  action="delete" cssClass="btn btn-default" /> 

네임 스페이스 구조를 따르도록 Actions 및 JSP의 패키지 구조도 리팩터링해야합니다.

<constant name="struts.mapper.action.prefix.enabled" value="true"/>

경우] :

PS : 당신이 Struts2 버전보다 높은 2.3.15.2를 사용하는 경우 this answer에 설명 된대로 행동 접두사가 사용 설정 기억 namespace은 JSP를 표시하는 데 사용하는 동작이 이 아니며은 작업과 동일합니다. cal 주도 (이 경우, /admin/product에), 당신이 <s:form> 태그를 지정해야합니다

<s:form namespace = "/admin/product" 
      enctype = "multipart/form-data" 
      theme = "simple" 
      role = "form"> 

과을 (당신이 Struts2 버전보다 높은 2.3.15.2를 사용하는 경우), 스트럿에서 다음 속성을 설정합니다. xml :

<constant name="struts.mapper.action.prefix.crossNamespaces" value="true"/> 

기본값으로 비활성화되어 있기 때문에 due to security reason.
