使用Spring MVC for REST时,如何让Jackson能够打印出漂亮的JSON？

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.12.4</version>
</dependency>

@Configuration
@EnableWebMvc
public class WebConfig implements WebMvcConfigurer {

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        converter.setObjectMapper(objectMapper());
        converters.add(converter);
    }

    @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.enable(SerializationFeature.INDENT_OUTPUT);
        return objectMapper;
    }
}

@RestController
public class UserController {

    @GetMapping("/users/{id}")
    public User getUser(@PathVariable Long id) {
        // 获取用户信息
        User user = userService.getUser(id);
        return user;
    }
}
