java - Spring Boot应用程序(特定于配置文件).properties返回null

Question

我正在尝试使用 springboot 将配置文件特定的属性文件值加载到我的 @webservice 类。我按照以下步骤操作，

1)

created application.properties with profile to be active
spring.profiles.active=dev

2)

Created application-dev.properties with following values
username = XXXXXXX
password = XXXXXXX
host = XXXXXXX
port = XXXXXXX
welcome.message = Development

3)

 Created @Springbootapplication class

4)

Created @configuration class for appconfig

5) 使用开始读取 appconfig 类中 application-dev.properties 的值

代码:

public class AppConfig {
@Value("${welcome.message}")
 private String welcomeMsg;
 @Profile("dev")
@Bean
public MessageSource messageSourceDev() {
System.out.println("****Dev Profile called*****"+welcomeMsg);

当我从 spring 工具套件运行时，第一次在控制台中成功打印欢迎消息。

“****开发人员简介称为*****开发”

但是当我尝试通过soap UI 从我创建的@webservice 类读取属性值时，

代码:

@WebService(serviceName = "SampleIF", endpointInterface   = "com.tc.services.sample.cxf.SampleIF")
public class SampleIFImpl implements SampleIF {
@Value("${welcome.message}")
private String welcomeMsg;
    @Override
public Contact CreateContract(Details details) {
    System.out.println("****Welcome Message Val*****"+welcomeMsg);

要么在 appconfig.class 处失败，抛出以下异常

1)

   org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'appConfig': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'welcome.message' in value "${welcome.message}"

2) 或带有 null 值的 @webservice 类

请帮我解决这个问题。

Answer 1

我重现了场景，但我在实现中做了一些更改

这是我的 application.yml

spring:
  profiles:
    active:
    - dev

这是我的 application-dev.yml

welcome:
  message: Development

最后，我直接使用需要该值的类中的变量

@Value("${welcome.message}")
private String welcomeMsg;
