java - GWT java.io.File 服务器包

Question

我已经找了几个小时了，但找不到我要找的东西。我知道 GWT 客户端包不支持 java.io.File。我想在服务器包中使用它。编译应用程序时出现以下错误:

Compiling module com.xxx.yyy.GWTApp
      Validating units:
  [ERROR] Errors in 'file:/.../workspace/GWTApp/src/com/xxx/yyy/server/Class1.java'
     [ERROR] Line 26: No source code is available for type java.io.File; did you forget to inherit a required module?
  [ERROR] Errors in 'file:/.../workspace/GWTApp/src/com/xxx/yyy/server/Class2.java'
     [ERROR] Line 104: No source code is available for type java.io.BufferedReader; did you forget to inherit a required module?
     [ERROR] Line 104: No source code is available for type java.io.FileReader; did you forget to inherit a required module?
     ...

任何想法可能是错误的？

编辑 *.gwt.xml 文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.5.1//EN"
  "http://google-web-toolkit.googlecode.com/svn/tags/2.5.1/distro-source/core/src/gwt-module.dtd">
<module rename-to='yyy'>
  <inherits name='com.google.gwt.user.User'/>
  <inherits name='com.google.gwt.user.theme.clean.Clean'/>
  <entry-point class='com.xxx.yyy.client.Yyy'/>
  <source path='client'/>
  <source path='shared'/>
  <source path='server'/>
  <inherits name="com.smartgwt.SmartGwt"/>
</module>

Answer 1

从您的 *.gwt.xml 中删除这一行:

<source path='server'/>

source标签用于标识需要编译成javascript的包。不应包括服务器包。
