在maven构建阶段更新jsp脚本标记 [英] updating jsp script tag during maven build phase
问题描述
我想更新src / main / webapp / jsp下的jsp文件中所有脚本标签内的内容。
如何在maven构建阶段执行此操作？
I want to update content inside all script tags in jsp files present under src/main/webapp/jsp. How to do this during maven build phase?
我使用的是java + spring + maven堆栈。
I am using java+spring+maven stack.
好的，这是我想要实现的例子：
Ok here is example of what I want to achieve:
源代码：
<%@ page contentType="text/html; charset=utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@ taglib prefix="s" uri="/struts-tags" %>
<script type="text/javascript" src="js/core/validator.js"></script>
<script type="text/javascript" src="js/app/util/core-util.js"></script>
<div id="dataContainer">
</div>
在maven构建之后，这应该出现在目标文件夹中
After maven build, this should be present in target folder
<%@ page contentType="text/html; charset=utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@ taglib prefix="s" uri="/struts-tags" %>
<script type="text/javascript" src="js/core/validator.js?version='<MD5SUM-of-js/core/validator.js>'"></script>
<script type="text/javascript" src="js/app/util/core-util.js?version='<MD5SUM-of-js/app/util/core-util.js>'"></script>
<div id="dataContainer">
</div>
请注意src =末尾的版本参数。
Please note the version parameter at the end of src="".
更新：最后，我能够按照以下方式开展工作。如果有的话，请随意建议替代。
Update: Finally, I was able to make it work following way. Feel free to suggest alternative if any.

准备shell脚本以生成类似这样的属性文件
Prepared shell script to generate properties file something like this
js / core / validator.js = js / core / validator.js？version \ = MD5SUM-of-js / core / validator.js
js / app / util / core-util.js = js / app / util / core-util.js？version \ = MD5SUM-of-js / app / util / core-util.js
js/core/validator.js=js/core/validator.js?version\=MD5SUM-of-js/core/validator.js
js/app/util/core-util.js=js/app/util/core-util.js?version\=MD5SUM-of-js/app/util/core-util.js
配置maven-replacer-plugin以将此属性文件用作标记值映射并过滤target / app / jsp文件夹下的所有jsp文件。
Configured maven-replacer-plugin to use this properties file as token value map and filter all the jsp files present under target/app/jsp folder.
推荐答案
你没有告诉你需要什么样的替代品，但是......
You didn't tell what kind of replacement you need, but...
对于很多情况，你可以使用常规的maven资源插件并打开过滤。这样它将用maven运行时属性替换任何 $ {values} 。
For lot of the cases, you can just use regular maven resources plugin and turn filtering on. That way it will replace any ${values} with maven runtime properties.
对于.jsps，您可能已经在使用war插件。使用war插件就像
For .jsps, you are possibly already using war plugin. With war plugin it is something like
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.2</version>
<configuration>
<webResources>
<resource>
<filtering>true</filtering>
<targetPath>WEB-INF</targetPath>
<directory>src/main/resources/WEB-INF</directory>
<includes>
<include>*.jsp</include>
</includes>
</resource>
</webResources>
</configuration>
</plugin>
然后你的JSP中有这样的东西：
Then you'd have something like this in your JSPs:
<script src="${mypath}/test.js"></script>
在maven pom中：
And in maven pom:
<properties>
<mypath>testpath</mypath>
</properties>
取决于您的项目配置。 （例如，经常使用src / main / webapp）
Depending on your project configuration. (src/main/webapp is often used as well, for example)
编辑：您在评论中添加了你有一个计算md5的shell脚本，你想使用它。我不知道这样做的优雅方式，所以建议一种不那么优雅的方式：使用groovy插件来执行脚本并获取属性的值。
you have added in the comments that you have a shell script counting md5 and you want to use that. I don't know an elegant way of doing that, so suggesting a less elegant way: use groovy plugin to execute the script and get the value to a property.
<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>gmaven-plugin</artifactId>
<version>1.5</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<providerSelection>2.0</providerSelection>
<properties>
<script>path/to/your/shell-script.sh</script>
</properties>
<!-- if the script prints its result to stdout -->
<source>
def command = project.properties.script
def process = command.execute()
process.waitFor()
def result = process.in.text.trim()
project.properties.md5Value = result
</source>
<!-- if the script prints the result to a file -->
<!-- note that you have to define this result file name somewhere -->
<source>
def command = project.properties.script
def process = command.execute()
process.waitFor()
def resultfile = new File(project.properties.result_file)
project.properties.md5Value = resultfile.getText()
</source>
<!-- only use one or the other script block! -->
</configuration>
</execution>
</executions>
</plugin>
