gwt別名資源與maven插件

Question

我使用gwt與maven插件。我web.xml看起來是這樣的：

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
      http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"> 

<!-- Servlets --> 
<servlet> 
    <servlet-name>queryServiceImpl</servlet-name> 
    <servlet-class>com.vo.search.server.QueryServiceImpl</servlet-class> 
</servlet> 

<servlet-mapping> 
    <servlet-name>queryServiceImpl</servlet-name> 
    <url-pattern>/admin/queryService</url-pattern> 
</servlet-mapping> 

<!-- Default page to serve --> 
<welcome-file-list> 
    <welcome-file>Admin.html</welcome-file> 
</welcome-file-list> 
</web-app> 

而我的模塊Admin.gwt.xml看起來是這樣的：

<module rename-to='admin'> 
<!-- Inherit the core Web Toolkit stuff. --> 
<inherits name="com.google.gwt.core.Core" /> 
<inherits name='com.google.gwt.user.User' /> 
<inherits name="com.google.gwt.i18n.I18N" /> 
<inherits name="com.google.gwt.i18n.CldrLocales" /> 
<inherits name="com.google.gwt.user.theme.clean.CleanResources" /> 

<!-- Enable debug ID. --> 
<inherits name="com.google.gwt.user.Debug" /> 
<set-property name="gwt.enableDebugId" value="true" /> 

<!-- We need the JUnit module in the main module, --> 
<!-- otherwise eclipse complains (Google plugin bug?) --> 
<!-- <inherits name='com.google.gwt.junit.JUnit' /> --> 

<!-- Inherit the default GWT style sheet. You can change --> 
<!-- the theme of your GWT application by uncommenting --> 
<!-- any one of the following lines. --> 
<inherits name='com.google.gwt.user.theme.clean.Clean' /> 
<!-- <inherits name='com.google.gwt.user.theme.standard.Standard'/> --> 
<!-- <inherits name='com.google.gwt.user.theme.chrome.Chrome'/> --> 
<!-- <inherits name='com.google.gwt.user.theme.dark.Dark'/> --> 

<!-- Other module inherits --> 

<!-- Specify the app entry point class. --> 
<entry-point class='com.vo.search.client.Admin' /> 

<!-- Specify the app entry point class. --> 

<!-- Specify the paths for translatable code --> 
<source path='client' /> 
<source path='shared' /> 


</module> 

最後，我pom.xml看起來是這樣的：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

構建和運行項目工作正常。當試圖訪問我在控制檯中看到的頁面：

[WARN] Aliased resource: file:/C:/workspaces/search/admin-mvn/search-admin/src/main/webapp/admin/admin.nocache.js==file:/C:/workspaces/search/admin-mvn/search-admin/src/main/webapp/Admin/Admin.nocache.js 
[WARN] Aliased resource: file:/C:/workspaces/search/admin-mvn/search-admin/src/main/webapp/admin/admin.nocache.js==file:/C:/workspaces/search/admin-mvn/search-admin/src/main/webapp/Admin/Admin.nocache.js 
[WARN] 404 - GET /admin/admin.nocache.js (127.0.0.1) 1408 bytes 
    Request headers 
     Host: 127.0.0.1:8888 
     Connection: keep-alive 
     User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.4 (KHTML, like  Gecko) Chrome/22.0.1229.39 Safari/537.4

    Response headers 
     Content-Type: text/html; charset=iso-8859-1 
     Content-Length: 1408 

我認爲問題是，它看起來文件admin.nocache.js在admin DIR但是生成的目錄實際上是Admin即使我rename-to屬性是admin模塊中配置文件。更改rename-to屬性以匹配沒有幫助。

這是一個被gwt-maven-plugin archetype創建了項目組織：

Answer 1

請檢查您的Admin.html。我認爲admin.nocache.js應該是：

<script type="text/javascript" language="javascript" src="../admin/admin.nocache.js"></script> 

您的文件 ... search-admin/src/main/webapp/Admin/Admin.nocache.js

應該在這裏： ... search-admin/src/main/Admin/Admin.nocache.js

Answer 2

如果你使用谷歌Eclipse插件（而不是mvn gwt:run）推出DevMode的，然後按照這些規則：https://developers.google.com/eclipse/docs/faq#gwt_with_maven

特別是，最重要的是，不要選擇src/main/webapp作爲WAR目錄，這就是爲什麼DevMode的在那裏產生的文件，它只能導致你的問題：GWT module may need to be (re)compiled REDUX
