如何使Spring Boot JSON输出可选择格式化(漂亮打印)

默认情况下使用 Spring Boot 控制器返回缩小的JSON,但是对于某些请求,如果传递了特殊的请求参数,响应应该是相当格式化的。例如:

http://test.com/health =>返回缩小的JSON

http://test.com/health?pretty =>返回相当格式化的JSON

如何扩展请求映射处理程序/控制器以选择性地格式化输出并保持生成的mime类型application/json

@RequestMapping(
            value = {"/health", "/"},
            produces = APPLICATION_JSON_VALUE)
public ResponseEntity<?> checkHealth(@RequestParam(required = false, value = "pretty") String prettyapplicationInfo) {
    final Map<String, Object> response = getResponse();

    if (pretty != null) {
        // so, how to format the response, if "pretty" property is specified? 
    }

    return new ResponseEntity<>(response, HttpStatus.OK);

}
