maven-war-plugin的encoding

    因为编程环境一直是linux，我一直采用的是UTF-8万能编码。

最近svn co了一个GB18030的项目。mvn war:war打包部署发现了很多配置文件中文乱码，导致启动时解析出错。

我一直以为是maven-resource-plugin的问题，

 

/**
     * <b>If wrappers is null or empty, the file will be copy only if to.lastModified() < from.lastModified()</b>
     * @param from the file to copy
     * @param to the destination file
     * @param encoding the file output encoding (only if wrappers is not empty)
     * @param wrappers array of {@link FilterWrapper}
     * @throws IOException if an IO error occurs during copying or filtering
     */
    public static void copyFile( File from, File to, String encoding, FilterWrapper[] wrappers )
        throws IOException
    {
        copyFile( from, to, encoding, wrappers, false );
    }

  反复查看了这个plugin的源代码之后发现它确实是采用pom里的encoding过滤文件。但是出war包里就是乱码，没天理啊。

 

很久之后我才想到可能是maven-war-plugin的问题。google一搜在官网发现了一个todo 

org.apache.maven.plugin.war.packaging.AbstractWarPackagingTask Line

add encoding support (null mean platform encoding)

 

看了下源代码

 

        if ( context.getWebappStructure().registerFile( sourceId, targetFilename ) )
        {
            final File targetFile = new File( context.getWebappDirectory(), targetFilename );
            try
            {
                // fix for MWAR-36, ensures that the parent dir are created first
                targetFile.getParentFile().mkdirs();
                // TODO: add encoding support (null mean platform encoding)
                context.getMavenFileFilter().copyFile( file, targetFile, true, context.getFilterWrappers(), null );
            }
            catch ( MavenFilteringException e )
            {
                throw new MojoExecutionException( e.getMessage(), e );
            }
            // Add the file to the protected list
            context.getLog().debug( " + " + targetFilename + " has been copied (filtered)." );
            return true;
        }
        else
        {
            context.getLog().debug(
                " - " + targetFilename + " wasn't copied because it has already been packaged (filtered)." );
            return false;
        }
    }

 

  context.getMavenFileFilter().copyFile( file, targetFile, true, context.getFilterWrappers(), null );

encoding是null啊，默认用环境的encoding，坑爹啊
