使用spring.application.json爲application.properties文件中的春天開機

我試圖從春天文檔使用命令-Dspring.application.json='{"foo":{"bar":"spam"}}'但是當看到它在的IntelliJ的運行命令它總是失敗，Could not resolve placeholder使用spring.application.json爲application.properties文件中的春天開機

我曾嘗試使用系統變量和Java Ops變量沒有成功。

我有什麼明智代碼： Application.properties：

testing=${foo.bar}

Application.java

@SpringBootApplication 
@ComponentScan 
public class Application extends RepositoryRestMvcConfiguration { 

    @Value("${testing:}") 
    private String input; 

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

    @Bean 
    public BatchDetails set() { 
     System.out.println("input: " + input); 
     return new BatchDetails("Test", "Test2"); 
    } 
}

的IntelliJ VM選項： -Dspring.application.json='{"foo":{"bar":"spam"}}'

的IntelliJ環境變量： SPRING_APPLICATION_JSON = '{"foo":{"bar":"spam"}}'

上的應用程序，我得到以下堆棧跟蹤的啓動：

我只是把配置在錯誤的地方這個工作？

你不能像這樣擴大Spring的application.properties。系統級別的所有值和系統級別spring.application.json都會加載到您的Environment變量中，您可以從那裏訪問foo.bar。

所以，基本上..

春天從application.properties期待完全形成值取testing，那麼它需要的JSON從你的系統變量，期待完全形成值並將它們合併成Environment。現在

你可以做

@Autowired 
private Environment env; 

env.getProperty("testing"); 
env.getProperty("foo.bar"); 

//OR 
@Value(${"foo.bar"}) 
private String valueFromFooBar

所以我嘗試了'@ Value'，它仍然不喜歡它。我真的想在本地模擬PCF的VCAP_SERVICES，所以我不想使用環境。我將在本地使用-Dfull.name.of.service =值。 – sherring
