java - spring boot 在命令行上运行时不读取 application.properties 文件但在 STS 中工作

问题描述

我正在使用 STS 4 IDE 开发一个带有 Spring Boot 的桌面应用程序。在 STS 中一切正常，我有不同的属性文件用于不同的配置文件，主属性文件 application.properties 都在资源文件夹中

src/main/resources
application.properties
application-dev.properties
application-prod.properties

在application.properties中，我定义了要扫描的环境和包，以查找两个应用程序数据库的实体：

spring.profiles.active=dev
wms.basepackage=com.wms
app.basepackage=es.app

我使用引导仪表板运行应用程序，一切正常。问题是在导出 JAR 时，我使用指令从命令中执行它

java -jar -Dspring.profiles.active=dev RunableApp4.jar

应用程序失败并出现以下错误：

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [es.app.InterfaceApplication]; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'wms.basepackage' in value "${wms.basepackage}"

我在日志中注意到从命令行运行应用程序的步骤与使用 STS 运行时的步骤不同：

STS 步骤（使用引导仪表板）：

es.app.InterfaceApplication      Starting InterfaceApplication on matias-pc with PID 27945 (/home/matias/desarrollo/InterfaceApp/bin/main started by matias in /home/matias/desarrollo/InterfaceApp)
es.app.InterfaceApplication      The following profiles are active: dev
o.s.boot.SpringApplication                 Loading source class es.app.InterfaceApplication

o.s.b.c.c.ConfigFileApplicationListener    Profiles already activated, '[dev]' will not be applied
o.s.b.c.c.ConfigFileApplicationListener    Loaded config file 'file:/home/matias/desarrollo/InterfaceApp/bin/main/application.properties' (classpath:/application.properties)

m.s.d.r.c.RepositoryConfigurationDelegate   Bootstrapping Spring Data JPA repositories in DEFAULT mode.
m.s.d.r.c.RepositoryConfigurationDelegate   Finished Spring Data repository scanning in 8ms. Found 4 JPA repository interfaces.

ConfigFileApplicationListener进入场景，加载主 application.properties文件 和 application-dev.properties环境文件。然后RepositoryConfigurationDelegate正确加载存储库

命令行步骤：

java -jar -Dspring.profiles.active=dev RunableApp4.jar
13:07:49.453 [main] DEBUG org.springframework.core.env.PropertySourcesPropertyResolver - Found key 'spring.profiles.active' in PropertySource 'systemProperties' with value of type String

Read candidate components

ConfigFileApplicationListener和RepositorConfigurationDelegate没有到达现场，AnnotationConfigApplicationContext 开始扫描组件，由于无法解析属性值而失败。

我已经尝试将属性文件作为参数发送，但结果是一样的：

java -jar -Dspring.profiles.active=dev  -Dspring.config.location=file:/InterfaceApp/src/main/resources/application.properties RunableApp4.jar

主要课程有：

@SpringBootApplication
@Import(ConfigInterfaceApp.class)
@EnableScheduling
public class InterfaceApp  {

    public static void main(String[] args) {
        SpringApplication.run(InterfaceApp.class, args);
    }


@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages = {"${wms.basepackage}", "${app.basepackage}"})
public class ConfigInterfaceApp {

}

我究竟做错了什么？

解决方案

阅读application.properties您的应用程序，如下所示：

ClassLoader.class.getResourceAsStream("/path/to/application.properties");

或者，

ClassLoader.getResourceAsStream("/application.properties");
