Maven：自定义web-app项目的web.xml [英] Maven: Customize web.xml of web-app project

问题描述

我有一个Web应用程序Maven项目，我想根据正在运行的配置文件自定义web.xml文件。我正在使用Maven-War-plugin，它允许我定义一个资源目录，可以过滤文件。但是，单独过滤对我来说还不够。

更详细地说，我想包含（或排除）关于安全性的整个部分，取决于我正在运行的配置文件。这是部分：

  .... 
 .... 
 
< security-constraint> 
 
< web-resource-collection> 
< web-resource-name> protected< / web-resource-name> 
< url-pattern> / pages / * .xhtml< / url-pattern> 
< url-pattern> / pages / * .jsp< / url-pattern> 
< / web-resource-collection> 
 
< auth-constraint> 
< role-name> *< / role-name> 
< / auth-constraint> 
 
< / security-constraint> 
< login-config> 
< auth-method> $ {web.modules.auth.type}< / auth-method> 
< realm-name> MyRealm< / realm-name> 
< / login-config> 
 
< security-constraint> 
 
 .... 
 .... 
  

如果这是不容易做到的，有没有办法有两个web.xml文件，并根据配置文件选择适当的？

是的，在每个配置文件中，您可以添加 maven-war-plugin 并将每个配置为指向不同的 web.xml 。

 < profiles> 
< profile> 
< id> profile1< / id> 
< build> 
< plugins> 
< plugin> 
< groupId> org.apache.maven.plugins< / groupId> 
< artifactId> maven-war-plugin< / artifactId> 
< configuration> 
< webXml> / path / to / webXml1< / webXml> 
< / configuration> 
< / plugin> 
 ... 
  

作为必须指定 maven-war-plugin 每个配置文件中的配置，你可以在POM的主要部分提供默认配置，然后只为特定的配置文件覆盖它。

或者更简单，在主<$ c您的POM的$ c>< build>< plugins> ，使用属性来引用 webXml 属性，然后只需更改它的值在不同的个人资料中

 < properties> 
< webXmlPath> path / to / default / webXml< / webXmlPath> 
< / properties> 
< profiles> 
< profile> 
< id> profile1< / id> 
< properties> 
< webXmlPath>路径/到/ custom / webXml< / webXmlPath> 
< / properties> 
< / profile> 
< / profiles> 
< build> 
< plugins> 
< plugin> 
< groupId> org.apache.maven.plugins< / groupId> 
< artifactId> maven-war-plugin< / artifactId> 
< configuration> 
< webXml> $ {webXmlPath}< / webXml> 
< / configuration> 
< / plugin> 
 ... 
  

I have a web application Maven project, and I want to customize the web.xml file depending on the Profile that is running. I am using the Maven-War-plugin, which allows me to define a "resources" directory, where the files may be filtered. However, filtering alone is not sufficient for me.

In more detail, I want to include (or exclude) the whole section on security, depending on the profile I an running. This is the part:

....
....

<security-constraint>

    <web-resource-collection>
        <web-resource-name>protected</web-resource-name>
        <url-pattern>/pages/*.xhtml</url-pattern>
        <url-pattern>/pages/*.jsp</url-pattern>
    </web-resource-collection>

    <auth-constraint>
        <role-name>*</role-name>
    </auth-constraint>

    </security-constraint>
        <login-config>
        <auth-method>${web.modules.auth.type}</auth-method>
        <realm-name>MyRealm</realm-name>
    </login-config>

<security-constraint>

....
....

If this is not done easily, is there a way to have two web.xml files and select the appropriate one depending on the profile?

Yes, within each profile you can add a configuration of the maven-war-plugin and configure each to point at a different web.xml.

<profiles>
    <profile>
        <id>profile1</id>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-war-plugin</artifactId>
                    <configuration>
                        <webXml>/path/to/webXml1</webXml>
                    </configuration>
                </plugin>
                 ...

As an alternative to having to specify the maven-war-plugin configuration in each profile, you can supply a default configuration in the main section of the POM and then just override it for specific profiles.

Or to be even simpler, in the main <build><plugins> of your POM, use a property to refer to the webXml attribute and then just change it's value in different profiles

<properties>
    <webXmlPath>path/to/default/webXml</webXmlPath>
</properties>
<profiles>
    <profile>
        <id>profile1</id>
        <properties>
            <webXmlPath>path/to/custom/webXml</webXmlPath>
        </properties>
    </profile>
</profiles>
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <configuration>
                <webXml>${webXmlPath}</webXml>
            </configuration>
        </plugin>
        ...
