我在使用Spring Boot和Spock框架进行集成测试时遇到问题。测试期间收到的错误"关于" http：//localhost：8080/farm "的GET请求的I/O错误"：连接被拒绝："
我的猜测是应用程序在集成测试期间无法启动，但我不知道为什么。我已经尝试了多种方法来解决它，但我没有想法
我的控制器集成测试代码：

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ActiveProfiles("test")
class FarmControllerTest extends Specification {
    RestTemplate restTemplate = new RestTemplate()

    def "integration test test"() {
        when: "test"
        def res = restTemplate.getForEntity("http://localhost:8080/farm", String.class)

        then: "assert"
        res.body == "implement getting farm for logged in user"
    }

}

I/O error on GET request for "http://localhost:8080/farm": Connection refused: connect
