使用spring.application.json为application.properties文件中的春天开机

我试图从春天文档使用命令-Dspring.application.json='{"foo":{"bar":"spam"}}'但是当看到它在的IntelliJ的运行命令它总是失败，Could not resolve placeholder使用spring.application.json为application.properties文件中的春天开机

我曾尝试使用系统变量和Java Ops变量没有成功。

我有什么明智代码： 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选项： -Dspring.application.json='{"foo":{"bar":"spam"}}'

的IntelliJ环境变量： SPRING_APPLICATION_JSON = '{"foo":{"bar":"spam"}}'

上的应用程序，我得到以下堆栈跟踪的启动：

你不能像这样扩大Spring的application.properties。系统级别的所有值和系统级别spring.application.json都会加载到您的Environment变量中，您可以从那里访问foo.bar。

所以，基本上..

春天从application.properties期待完全形成值取testing，那么它需要的JSON从你的系统变量，期待完全形成值并将它们合并成Environment。现在

你可以做

@Autowired 
private Environment env; 

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

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

所以我尝试了'@ Value'，它仍然不喜欢它。我真的想在本地模拟PCF的VCAP_SERVICES，所以我不想使用环境。我将在本地使用-Dfull.name.of.service =值。 – sherring
