激活资源过滤后的编码错误 [英] Wrong encoding after activating resource filtering

问题描述

我正在开发一个基于maven的Web项目。在我的Web模块中，我使用不同的语言特定的资源包（德语，西班牙语，....）。
我所有的来源都是以UTF-8为基础，而且这些都可以正常工作。
现在有必要使用maven资源过滤来替换一些配置，具体取决于不同的maven配置文件。

我的pom.xml：

  ..... 
< project xmlns =http://maven.apache.org/POM/4.0.0xmlns：xsi =http://www.w3.org/2001/XMLSchema-instance
 xsi：schemaLocation =http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd\"> 
 ..... 
 
< properties> 
< project.build.sourceEncoding> UTF-8< /project.build.sourceEncoding> 
< / properties> 
< build> 
< resources> 
< resource> 
< directory> src / main / resources< / directory> 
< filtering> true< / filtering> 
< / resource> 
< / resources> 
 .... 
  

从这一刻起，我的war文件包含编码错误的资源包。例如德语变音符不再显示在我的Web应用程序中。
当我禁用资源过滤时，一切都很好。

我发现唯一的解决方案是将property.build.sourceEncoding属性设置为'ISO-8859 -1'

 <属性> 
< project.build.sourceEncoding> ISO-8859-1< /project.build.sourceEncoding> 
< / properties> 
  

但我不明白为什么这是必要的？我所有的来源都是UTF-8，我的应用程序是基于UTF-8的？
如果我需要添加一个资源包（例如日文字符）会发生什么？

我正在使用Eclipse 4.2和Maven 3开发linux， p>

解决方案

确定您的资源包（.properties）正在使用 UTF-8 ？

java.util.Properties 假定 ISO-8859-1 用于资源束编码，请参见 http://docs.oracle.com/javase/6/docs/api/java/util/Properties.html#load（java.io.Reader），我认为Eclipse（as以及IntelliJ IDEA）为这些文件（.properties）授予这种默认编码。

所以，使用文本编辑器检查项目源代码树中这些文件的当前编码，在Windows 记事本2 中可以帮助您

然后配置 maven-resources-plugin 如下所示在maven中配置不同文件类型的编码？

I am developing a maven based web project. In my web module I am using different language specific resource bundles (german, spain, ....). All my sources are based on UTF-8 and erverything works fine. Now it was necessary to acitvate maven resouce filtering to replace some configurations depending on different maven profiles.

my pom.xml:

.....
 <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/xsd/maven-4.0.0.xsd">
.....

 <properties>
     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
 </properties>    
 <build>
 <resources>
    <resource>
    <directory>src/main/resources</directory>
        <filtering>true</filtering>             
    </resource>      
 </resources>
 ....

From this moment my war file contains resource bundles with wrong encoding. For example German umlauts are no longer displayed in my web application correctly. When I disable the resource filtering everything is well again.

The only solution I found was to set the property project.build.sourceEncoding to 'ISO-8859-1'

<properties>
  <project.build.sourceEncoding>ISO-8859-1</project.build.sourceEncoding>
</properties>

But I can not understand why this is necessary? All my sources are UTF-8 and also my application is based on UTF-8? What will happen if I need to add a resource bundle with - for example Japanese characters?

I am developing on linux using Eclipse 4.2 and Maven 3

解决方案

Are you sure your resource bundles (.properties) are using UTF-8?

java.util.Properties assumes ISO-8859-1 for resource bundles encoding, see http://docs.oracle.com/javase/6/docs/api/java/util/Properties.html#load(java.io.Reader), and I think Eclipse (as well as IntelliJ IDEA) honors this default encoding for these files (.properties).

So go and check with a text editor the current encoding for these files in your project source tree, in Windows Notepad 2 can help you with this.

And then configure maven-resources-plugin like indicated here Configure encoding for different filetypes in maven?
