YUI Compressor Maven插件压缩 js、css并输出war包
YUI Compressor是一款非常强大JS混淆和压缩工具。目前很多Javascript框架都使用YUI Compressor进行了代码压缩。据说鼎鼎有名的Jquery框架也是使用YUI Compressor进行压缩。YUI Compressor压缩的好处是不仅大大减少js、css的体积,同时在对javascript代码的混淆压缩中对属性命名的替换,使得压缩过的js不易阅读,能起到源码的保护作用。本文主要介绍YUI Compressor的使用方法和技巧。
一、在Maven pom.xml文件中,添加YUI Compressor 插件。代码如下:
<plugin> <groupId>net.alchim31.maven</groupId> <artifactId>yuicompressor-maven-plugin</artifactId> <version>1.3.0</version> <executions> <execution> <goals> <goal>compress</goal> </goals> </execution> </executions> <configuration> <skip>false</skip> <!-- 读取js,css文件采用UTF-8编码 --> <encoding>UTF-8</encoding> <jswarn>false</jswarn> <!-- 若存在已压缩的文件,会先对比源文件是否有改动。有改动便压缩,无改动就不压缩 --> <force>false</force> <!-- <suffix>.min</suffix> --> <nosuffix>true</nosuffix> <!-- 在指定的列号后插入新行 --> <linebreakpos>-1</linebreakpos> <!-- 压缩之前先执行聚合文件操作 --> <preProcessAggregates>true</preProcessAggregates> <aggregations> <aggregation> <removeIncluded>true</removeIncluded> <insertNewLine>true</insertNewLine> <inputDir>${project.build.directory}/${project.build.finalName}/resources/static/js </inputDir> <output>${project.build.directory}/${project.build.finalName}/build/js/basic.min.js </output> <includes> <include>jquery-1.7.2.js</include> <include>everycoding.js</include> <include>front.js</include> </includes> </aggregation> <aggregation> <insertNewLine>true</insertNewLine> <inputDir>${project.build.directory}/${project.build.finalName}/resources/static/css </inputDir> <output>${project.build.directory}/${project.build.finalName}/build/css/basic.min.css </output> <includes> <include>common.css</include> <include>front.css</include> </includes> </aggregation> </aggregations> </configuration></plugin>
aggregations:管理需要分类合并的Js、Css
二、使用Maven命令执行压缩:
mvn yuicompressor:compress
三、打war时,如果需要排除未压缩的js、css文件,可使用如下方法:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.4</version> <configuration> <warSourceExcludes>**/*.js,**/*.css</warSourceExcludes> </configuration></plugin>

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.

HTML is the cornerstone of building web page structure. 1. HTML defines the content structure and semantics, and uses, etc. tags. 2. Provide semantic markers, such as, etc., to improve SEO effect. 3. To realize user interaction through tags, pay attention to form verification. 4. Use advanced elements such as, combined with JavaScript to achieve dynamic effects. 5. Common errors include unclosed labels and unquoted attribute values, and verification tools are required. 6. Optimization strategies include reducing HTTP requests, compressing HTML, using semantic tags, etc.

HTML is a language used to build web pages, defining web page structure and content through tags and attributes. 1) HTML organizes document structure through tags, such as,. 2) The browser parses HTML to build the DOM and renders the web page. 3) New features of HTML5, such as, enhance multimedia functions. 4) Common errors include unclosed labels and unquoted attribute values. 5) Optimization suggestions include using semantic tags and reducing file size.
