三、应用配置引用 maven、gradle 里的变量
这是编译工具的功能。通过 resources 处理配置,添加需要被渲染的资源:
1、配置参考
- maven
<properties>
<demo.env>local</demo.env>
</properties>
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>*.yml</include>
</includes>
</resource>
<resource>
<directory>src/main/resources</directory>
<filtering>false</filtering>
<excludes>
<exclude>*.yml</exclude>
</excludes>
</resource>
</resources>
</build>
当有 "resource" 配置时,需要把所有资源都包括进去。
- gradle
ext {
demo_env = "local"
}
import org.apache.tools.ant.filters.ReplaceTokens
processResources {
filesMatching('app.yml') {
def tokens = [:]
project.properties.each { key, value ->
if (value != null) {
tokens[key] = value.toString()
}
}
filter(ReplaceTokens, tokens: tokens)
}
}
2、引用方式
- yaml
solon.env: @demo.env@
- properties
solon.env=@demo.env@
