这里有点不知所措。我有一个示例应用程序/概念验证,我试图使用以下配置:
第1层:利用Spring组件的库,远离最终用户库/应用程序。
第2层:引入上述库的库,但在其他方面是非Spring实现的。足够聪明以自动建立Spring上下文,但隐藏了库的用户的详细信息。
第3层:使用"中间件"的应用程序第2层中的库,也是非Spring感知的。
我所有这一切都按预期工作,甚至能够设置活动配置文件(spring.profiles.active)并从第3层应用程序的类路径中获取正确的属性文件。这是奇怪的:
如果我从IDE(IntelliJ)运行应用程序并让它在命令行上传递活动配置文件,则所有操作都按预期工作。我从我的"生产"加载的值属性文件覆盖默认属性文件中的属性文件。也就是说,application.properties
中的键X值会覆盖java -Dspring.profiles.active=production -jar my-app-1.0-SNAPSHOT-full.jar
中的X值。
一切都好,对吗?好的,尝试从命令行运行jar做同样的事情(application.properties
)。我在调试日志中看到"生产"拾取属性文件,但默认文件优先。也就是说,正在使用application-production.properties
中的值,即使Spring上下文明确指出" production"是活动的,它找到并加载william@jessie:/mnt/builds/william/src/mixed-spring-legacy-app$ java -Dspring.profiles.active=production -jar example-app/target/example-app-1.0-SNAPSHOT-full.jar

就好了。
呃,WAT?!
有没有其他人经历过这种情况,如果是,有任何解决方法吗?我正在使用Spring IO Platform Brussels-SR5,其中包括版本4.3.11.RELEASE的spring-core,spring-context等。应用程序的jar是一个包含所有依赖项的阴影jar。两个图书馆罐子没有阴影。

Hi, Jack!
因此,您可以在此处看到特定于配置文件的属性文件被设置为低于catch-all属性文件的优先级。此外,
{{1}}
在我实际调用bean的地方,我添加了代码以显示哪些配置文件处于活动状态,以及属性值包含的内容。
正如我之前所说,从我的IDE运行时,这可以正常工作,但不能从jar文件运行。
编辑#2
所以我尝试从jar中删除属性文件并在当前目录中运行它们。结果相同。将jar转储到一个文件夹,将属性文件添加到该文件夹...就像它应该的那样工作。所以它绝对与混合罐中的东西有关。
答案 0 :(得分:1)
所以我终于想出了一个解决方法。至于为什么它与文件夹中的所有类/属性文件一起使用而不是在jar中,我可以给出的最佳答案是“紫色,因为外星人不戴帽子。”
无论如何,我必须做的是添加另一个特定于“默认”配置文件的“profiled”属性类。这将接收“application-default.properties”文件中的任何内容,并且只有在未激活其他配置文件时才会激活。 “application.properties”文件不应包含基于活动配置文件覆盖的数据。
这是如何工作的代码示例...
Catch-all / root配置
package tech.chihuahua.examples.config;
import org.springframework.context.annotation.*;
import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
import tech.chihuahua.examples.service.GreetingService;
@Configuration
@ComponentScan("tech.chihuahua.examples")
public class LibraryContext {
@Configuration
@PropertySources({
@PropertySource(
value = "${spring.config.location}/application.properties",
ignoreResourceNotFound = true),
@PropertySource(
value = "classpath:application.properties",
ignoreResourceNotFound = true)
})
static class ApplicationProperties {}
@Bean
GreetingService greetingService() {
return new GreetingService();
}
@Bean
static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
}
默认值,适用于没有配置文件处于活动状态的
package tech.chihuahua.examples.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import org.springframework.context.annotation.PropertySource;
import org.springframework.context.annotation.PropertySources;
@Configuration
public class LibraryDefaultContext {
@Profile("default")
@Configuration
@PropertySources({
@PropertySource(
value = "${spring.config.location}/application-default.properties",
ignoreResourceNotFound = true),
@PropertySource(
value = "classpath:application-default.properties",
ignoreResourceNotFound = true)
})
static class DefaultProperties {}
}
生产资料有效
package tech.chihuahua.examples.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import org.springframework.context.annotation.PropertySource;
import org.springframework.context.annotation.PropertySources;
import tech.chihuahua.examples.Profiles;
@Configuration
public class LibraryProductionContext {
@Profile(Profiles.PRODUCTION)
@Configuration
@PropertySources({
@PropertySource(
value = "${spring.config.location}/application-production.properties",
ignoreResourceNotFound = true),
@PropertySource(
value = "classpath:application-production.properties",
ignoreResourceNotFound = true)
})
static class ProductionProperties {}
}
暂存资料
package tech.chihuahua.examples.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import org.springframework.context.annotation.PropertySource;
import org.springframework.context.annotation.PropertySources;
import tech.chihuahua.examples.Profiles;
@Configuration
public class LibraryStagingContext {
@Profile(Profiles.STAGING)
@Configuration
@PropertySources({
@PropertySource(
value = "${spring.config.location}/application-staging.properties",
ignoreResourceNotFound = true),
@PropertySource(
value = "classpath:application-staging.properties",
ignoreResourceNotFound = true)
})
static class StagingProperties {}
}
有了所有这些,建立超级罐。如果需要,请在jar中包含属性文件,或者确保它们在计算机上的文件夹中可用(例如/ etc / my-app)。
# The general application configuration settings go here.
/etc/my-app/application.properties
# The default configuration settings go here
# (e.g. configure the application to use an in-memory database)
/etc/my-app/application-default.properties
# The production configuration settings go here
# (e.g. configure the application to use your production database)
/etc/my-app/application-production.properties
# The staging configuration settings go here
# (e.g. configure the application to use a staging/test database)
/etc/my-app/application-staging.properties
使用默认设置执行应用
如果未指定其他配置文件,Spring将自动将“默认”配置文件设置为活动状态。所以这里将拾取“application-default.properties”文件,并将使用其配置。
# Using the properties files in the classpath in the jar
java -jar my-app-1.0-SNAPSHOT-full.jar
# Using the properties files on the file system
java -Dspring.config.location=file:///etc/my-app \
-jar my-app-1.0-SNAPSHOT-full.jar
执行生产资料激活的应用
启用“生产”配置文件后,将不会激活“默认”配置文件。因此,将忽略“application-default.properties”,并加载“application-production.properties”。
# Using the properties files in the classpath in the jar
java -Dspring.profiles.active=production \
-jar my-app-1.0-SNAPSHOT-full.jar
# Using the properties files on the file system
java -Dspring.profiles.active=production \
-Dspring.config.location=file:///etc/my-app \
-jar my-app-1.0-SNAPSHOT-full.jar
执行启用了暂存资料的应用
与之前相同,只使用“登台”配置文件而不是“生产”。
# Using the properties files in the classpath in the jar
java -Dspring.profiles.active=staging \
-jar my-app-1.0-SNAPSHOT-full.jar
# Using the properties files on the file system
java -Dspring.profiles.active=staging \
-Dspring.config.location=file:///etc/my-app \
-jar my-app-1.0-SNAPSHOT-full.jar
希望这有助于节省时间和恶化。
答案 1 :(得分:-1)
将属性名称括在下面的引号中,然后尝试。这应该起作用:
java -D"spring.profiles.active"=production -jar example-app/target/example-app-1.0-SNAPSHOT-full.jar
请确认建议的更改是否可以解决问题。
