效果就是改源码。

啥时候改？可以通过插件直接改，也可以通过maven phase 改

怎么改？目标文本文件中包含 ${...}

如何控制范围？通过include exclude 进行配置

Required Parameters

Name	Type	Since	Description
outputDirectory	`File`	`-`	The output directory into which to copy the resources. Default value is: `${project.build.outputDirectory}`.

Optional Parameters

Name	Type	Since	Description
delimiters	`List`	`2.4`	Set of delimiters for expressions to filter within the resources. These delimiters are specified in the form 'beginTokenendToken'. If no '' is given, the delimiter is assumed to be the same for start and end. So, the default filtering delimiters might be specified as: <delimiters> <delimiter>${}</delimiter> <delimiter>@</delimiter> </delimiters> Since the '@' delimiter is the same on both ends, we don't need to specify '@@' (though we can).
encoding	`String`	`-`	The character encoding scheme to be applied when filtering resources. Default value is: `${project.build.sourceEncoding}`. User property is: `encoding`.
escapeString	`String`	`2.3`	Expression preceded with the String won't be interpolated \${foo} will be replaced with ${foo} User property is: `maven.resources.escapeString`.
escapeWindowsPaths	`boolean`	`2.4`	Whether to escape backslashes and colons in windows-style paths. Default value is: `true`. User property is: `maven.resources.escapeWindowsPaths`.
filters	`List`	`-`	The list of extra filter properties files to be used along with System properties, project properties, and filter properties files specified in the POM build/filters section, which should be used for the filtering during the current mojo execution. Normally, these will be configured from a plugin's execution section, to provide a different set of filters for a particular execution. For instance, starting in Maven 2.2.0, you have the option of configuring executions with the id's `default-resources` and `default-testResources` to supply different configurations for the two different types of resources. By supplying `extraFilters`configurations, you can separate which filters are used for which type of resource.
includeEmptyDirs	`boolean`	`2.3`	Copy any empty directories included in the Resources. Default value is: `false`. User property is: `maven.resources.includeEmptyDirs`.
mavenFilteringHints	`List`	`2.4`	List of plexus components hint which implements `MavenResourcesFiltering.filterResources()`. They will be executed after the resources copying/filtering.
nonFilteredFileExtensions	`List`	`2.3`	Additional file extensions to not apply filtering (already defined are : jpg, jpeg, gif, bmp, png)
overwrite	`boolean`	`2.3`	Overwrite existing files even if the destination files are newer. Default value is: `false`. User property is: `maven.resources.overwrite`.
supportMultiLineFiltering	`boolean`	`2.5`	stop searching endToken at the end of line Default value is: `false`. User property is: `maven.resources.supportMultiLineFiltering`.
useBuildFilters	`boolean`	`2.4`	If false, don't use the filters specified in the build/filters section of the POM when processing resources in this mojo execution. See also: `ResourcesMojo.buildFilters` and `ResourcesMojo.filters` Default value is: `true`.
useDefaultDelimiters	`boolean`	`2.4`	(no description) Default value is: `true`. 解释一下，如果是true则可以额外使用默认的两种'@' 和 '${*}' ，如果是false 则不可以使用默认的

关于delimiters 如何自定义：

元素中值的格式：开始符*结束符

如果没有星号，则认为给定的值是开始符，并且也是结束符

举例：

奇怪的问题，执行后 ${} 没有被替换，-X 详细日志发现 resource.delimiter=@

原因：没有指定 useDefaultDelimiters ，指定后还是 @ 不过${}可以被替换了，怪异！保险起见可以主动指定<delimiter>${*}</delimiter>

注意：如果想要使用'{{*}}' 不要配置成'{{' ，因为不对称，实际使用时是'{{someproperty}}' ，而不是'{{someproperty{{'

方式一：使用默认'@'和'${*}' ，不推荐，容易和spring 中的混淆

                </configuration>
            </plugin>
        </plugins>
    </build>

执行 mvn resources:resources
