Maven plugin wro4j-maven-plugin compression, merge JS, css detailed

1. In the Pom.xml file, introduce the Wro4j-maven-plugin plugin

2. <plugin>

6. <artifactId>wro4j-maven-plugin</artifactId>
8. <version>${wro4j.version}</version>

24. </goals>
26. </execution>

32. <configuration>
34. <ignoreMissingResources>false</ignoreMissingResources>
36. <jsDestinationFolder>
38. ${project.build.directory}/${project.build.finalname}/static/js
40. </jsDestinationFolder>
42. <cssDestinationFolder>
44. ${project.build.directory}/${project.build.finalname}/static/css
46. </cssDestinationFolder>
48. <wroManagerFactory>
50. Ro.isdc.wro.maven.plugin.manager.factory.ConfigurableWroManagerFactory
52. </wroManagerFactory>
54. </configuration>
56. </plugin>

2. Configure the merge, compression policy, new file/web-inf/wro.xml, for example, the configuration content is:

2. <? XML version="1.0" encoding="UTF-8"?>
4. <groups xmlns="Http://www.isdc.ro/wro" xmlns:xsi="http://www.w3.org/ 2001/xmlschema-instance "
6. xsi:schemalocation="Http://www.isdc.ro/wro wro.xsd">
8. <group name="Basic">
10. <css>/static/css/front.css</css>
12. <js>/static/js/jquery.js</js>
14. <js>/static/js/jquery.paging.min.js</js>
16. <js>/static/js/front/global.js</js>
18. <js>/static/js/front/search.js</js>
20. </group>
24. <group name="Custom">
26. <css>/static/css/front.css</css>
28. <css>/static/css/comment/comment.css</css>
30. <css>/static/plugins/syntaxhighlighter/shcore.css</css>
32. <js>/static/js/front/coding.js</js>
34. </group>
38. </groups>

3. Configure wro4j related properties and create a new web-inf/wro.properties, for example, the configuration content is:
Configuration attribute meaning See also: http://everycoding.com/coding/68.html

1. cacheupdateperiod=0
2. modelupdateperiod= 0
3. debug=true
4. disablecache=
5. gzipresources= true
6. ignoremissingresources=false

This plugin must be configured with Wro.properties. Otherwise, the following exception will be reported when the package command is executed: Clean packages:
Src\main\webapp\web-inf\wro.properties (the system cannot find the file specified.) ), [Help 1]

4. Execute MAVEN command: Clean package packaging
We will find that the policies configured according to the Wro.xml
${project.build.directory}/${project.build.finalname}/static/js
The ${PROJECT.BUILD.DIRECTORY}/${PROJECT.BUILD.FINALNAME}/STATIC/CSS directory generates a
Basic.css, Basic.js, Custom.css, custom.js, etc. merge compressed files.
