It seems that Spring doesn’t allow you to provide a static text for the cache key in the SPEL, and it doesn’t include as default the name of the method on the key, so, you could be in a situation when two methods using the same cacheName and without a key would potentially cache different … Read more
To read any file in the UTF-8 encoding it must be created in the UTF-8 before. Use some editor which supports encoding switching. Or create that file from IDE with encoding option for properties files. E.g. IDEA: http://blog.jetbrains.com/idea/2013/03/use-the-utf-8-luke-file-encodings-in-intellij-idea/
Even though Spring is open source and used and supported by a large community, its future development is controlled by a single company (spring source / vmware). As such, its decisions are inherently non-public and certainly influenced by a large number of factors – like the currents demands of the community, but certainly also financial … Read more
After playing a bit with various scenarios, here is the one way how can one achieve what was asked with minimal interventions to the main code Refactor your controller to use a parameter for thirdparty server address: @RestController public class HelloController { @Value(“${api_host}”) private String apiHost; @RequestMapping(“/hello_to_facebook”) public String hello_to_facebook() { // Ask facebook about … Read more

To listen on ports other than server.port and management.port: @Configuration public class EmbeddedTomcatConfiguration { @Value(“${server.additionalPorts}”) private String additionalPorts; @Bean public EmbeddedServletContainerFactory servletContainer() { … Read more
The config server is needed during bootstrap, and that’s where the parent property sources come from. It looks like all you need to do is move your spring.cloud.config.enabled property to bootstrap.yml (or .properties).
You’ll have to have a ContextLoaderListener in your web.xml – It loads your configuration files. <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> You need to understand the difference between Web application context and root application context . In the web MVC framework, each DispatcherServlet has its own WebApplicationContext, which inherits all the beans already defined in the root WebApplicationContext. … Read more
This is a Postman specific error and it is generated because there is a Max Response Size limit available in the settings. By default it is 50 MB.

As the bean name is the bean’s unique identifier in the Context, you can only have 1 bean named “foo”, whereas you can have multiple … Read more
