Answer

alexanoid. There are two method to pretty the output:

application.yml

spring:
  jackson:
    serialization:
      INDENT_OUTPUT: true

or

application.properties

spring.jackson.serialization.INDENT_OUTPUT=true

Reference: https://github.com/lenicliu/eg-spring/tree/master/eg-spring-boot/eg-spring-boot-pretty-json

Both of chrome and curl are works fine.

Pls check the location of application.yml, where are you put it into?

src/main/resources/application.yml

UPDATE

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        System.setProperty("spring.jackson.serialization.INDENT_OUTPUT", "true");
        SpringApplication.run(Application.class, args);
    }
}

Question 2

In my Spring Boot 1.3.3.RELEASE application Actuator's Health endpoint returns following JSON:

{"status":"UP","diskSpace":{"status":"UP","total":120031539200,"free":109277069312,"threshold":10485760}}

Instead of a single string I want to return pretty print JSON.

I have added following configuration into my application.yml:

spring:
  jackson:
    serialization:
      INDENT_OUTPUT: true

but output is still returns the same single string.

How to properly configure my application in order to return pretty-print JSON ?

UPDATED

This is my application.yml

server:
  port: @server.port@
  contextPath: /dashboard

management:
  contextPath: /actuator 

spring:
  jackson:
    serialization:
      INDENT_OUTPUT: true
  jmx:
    enabled: false
  aop:
    proxy-target-class: @spring.aop.proxy-target-class@
  security:
    bcryptPasswordEncoder:
      strength: @spring.security.bcryptPasswordEncoder.strength@
  datasource:
    driverClassName: @spring.datasource.driverClassName@
    url: @spring.datasource.url@
    username: @spring.datasource.username@
    password: @spring.datasource.password@
  jpa:
    database: @spring.jpa.database@
    database-platform: @spring.jpa.database-platform@
    hibernate.ddl-auto: @spring.jpa.hibernate.ddl-auto@
    show-sql: @spring.jpa.show-sql@

ok:
  client:
    clientSecret: @ok.client.clientSecret@
    clientPublicKey: @ok.client.clientPublicKey@
