如何在 Java 的 Cucumber 中使用参数类型代替正则表达式

Question

我有这个场景：

Scenario Outline: Client makes call to GET /entity with pagination
    When client calls /entity with <page> and <perPage>
    Then client receives status code of <status>

Examples:
  | page | perPage | status |
  | 1    | 5       | 200    |

这是生成的步骤定义：

import cucumber.api.java8.En;

@ContextConfiguration
@SpringBootTest(classes = App.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class EntityApiStepdefs implements En {
  
    public EntityApiStepdefs() {
    
        When("^client calls /entity with ([^\"]*) and ([^\"]*)$",
                    (Integer page, Integer perPage) -> {
        
        }
        
    }
}

如何删除 regex 并改用 参数类型 ？

像这样：

"^client calls /entity with ([^\"]*) and ([^\"]*)$"

为此：

"client calls /entity with {string} and {string}" 
// or:
"client calls /entity with {int} and {int}"

PS：我尝试时的错误是：“Undefined step reference”
