- build中resource解释:对资源文件进行复制时的选项。正常情况下maven只会将src/main/resource下的资源文件复制到jar包中,但是有时我们会在src/main/java下放文件如xxx.xml,此时需要进行配置达到一起打进jar包的目的。
(1)includes:包含文件;excludes:不包含文件
(2)targetPath:指定build资源到哪个目录
(3)directory:指定属性文件的目录,build的过程需要找到它,并且将其放到targetPath下
(4)filtering:表示资源文件在复制到目标目录时,是否选择替换占位符。当filtering = true时替换资源文件中的占位符;当filtering = false时不进行占位符的替换。
比如:
<build>
.......
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
</resources>
......
</build>
<!-- 上面的配置,解释如下:-->
<!--
将"src/main/java"目录下的所有的.properties和.xml文件进行打包,
并替换所有的.properties和.xml文件中的占位符。
占位符:${name}这样的符号
-->
- build中plugins的spring-boot-maven-plugin,加入repackage后的作用:
(1)在原始Maven打包形成的jar包基础上,进行重新打包,新形成的jar包不但包含应用类文件和配置文件,而且还会包含应用所依赖的jar包以及Springboot启动相关类(loader等),以此来满足Springboot独立应用的特性;
(2)将原始Maven打包的jar重命名为XXX.jar.original作为原始文件 - profiles,用来在多环境时使用,一般有dev、test、prod环境,配置好以后可以在application文件和pom文件中引用。在IDEA的maven -> Profiles中可以选择启动服务时用哪个环境;maven打包时用 -Ptest 可以打对应的包。
