Pretty print JSON output of Spring Boot Actuator endpoints

json spring spring-boot

As per http://docs.spring.io/spring-boot/docs/current/reference/html/howto-spring-mvc.html#howto-customize-the-jackson-objectmapper, the official way to enable pretty print with Jackson in Spring Boot (1.2.2 at least) is to set the following property:

 # Pretty-print JSON responses spring.jackson.serialization.indent_output=true

json spring spring-boot

For Spring Boot 1.5.1 I have in my YML file:

spring:  jackson:    serialization:      INDENT_OUTPUT: true

@BertrandRenuart answer was the closest, but by IDE did not see indent_output as correct.

json spring spring-boot

The "http.mappers" property works for me but I think you might need it camel cased ("jsonPrettyPrint").
