Is it possible to wire a Spring MVC Interceptor using annotations?

by

Stumbled upon this question while searching exactly this. Finally I found out that it works in Spring 3.1 using @EnableWebMVC in conjunction with WebMvcConfigurerAdapter.

Spring 3.0.5 doesn’t evaluate @Value annotation from properties

by

Found what the issue was. Copy/paste from comments: Are you sure you have <context:property-placeholder> in the same application context as your MyClass bean (not in the parent context)? – axtavt You’re right.

How to remove the “_embedded” property in Spring HATEOAS

by

I close HAL feature, because it is hard to using Resources/Resource by restTemplate. I disable this feature by following code: public class SpringRestConfiguration implements RepositoryRestConfigurer { @Override public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) { config.setDefaultMediaType(MediaType.APPLICATION_JSON); config.useHalAsDefaultJsonMediaType(false); } } It work for me. HAL is good if there are more support with restTemplate.

spring-boot-starter-tomcat vs spring-boot-starter-web

by

Since #1 supports Tomcat why would one want to use #2? spring-boot-starter-web contains spring-boot-starter-tomcat. spring-boot-starter-tomcat could potentially be used on its own if spring mvc isn’t needed (contained in spring-boot-starter-web).
