在测试SpringBoot web应用时，如何在groovy spock的"setup“中定义Get值？

import org.springframework.test.web.servlet.MockMvc
import org.springframework.test.web.servlet.setup.MockMvcBuilders
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest
import org.springframework.boot.test.context.SpringBootTest
import org.springframework.test.context.junit4.SpringRunner
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders
import org.springframework.test.web.servlet.result.MockMvcResultMatchers

@SpringBootTest
@WebMvcTest(YourController.class)
class YourControllerSpec extends Specification {

    @Autowired
    private MockMvc mockMvc

    def setup() {
        mockMvc = MockMvcBuilders.standaloneSetup(new YourController()).build()
    }

    def "test your controller"() {
        setup:
        def id = 1

        when:
        def result = mockMvc.perform(MockMvcRequestBuilders.get("/your-endpoint")
                .param("id", id.toString()))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andReturn()

        then:
        // 断言结果
        // ...
    }
}
