spring-引导抛出连接被拒绝的集成测试

Question

我在spring靴子上有一个

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = Application.class)
public class CustomerControllerIT {
    private RestTemplate restTemplate = new RestTemplate();

    @Test
    public void findAllCustomers() throws Exception {
        ResponseEntity<List<Customer>> responseEntity = restTemplate.exchange(
                "http://localhost:8080/Customer", HttpMethod.GET, null,
                new ParameterizedTypeReference<List<Customer>>() {
                });

        List<Customer> list = responseEntity.getBody();
        Assert.assertEquals(list.size(), 0);
    }

如果我对已启动的应用程序启动测试-测试确定如果我尝试只启动它，则会出现连接拒绝错误。

My Application.Properties对于单一启动和测试是相同的，并且位于resources和TestResources中。

application.class是

package mypackage;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@ComponentScan({"mypackage"})
@EntityScan(basePackages = {"mypackage.model"})
@EnableJpaRepositories(basePackages = {"mypackage.persistence"})
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

您必须使用正在运行的服务器运行测试,

如果需要启动一个完全运行的服务器，则必须使用随机端口，如果使用@springboottest(webenvironment=webenvironment.random_port)，则每次运行测试时都会随机选择一个可用端口。

您需要这个maven依赖项

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-test</artifactId>        
</dependency>

请阅读文档以获得更多参考

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT)
public class TestRest {

    @Autowired
    private TestRestTemplate restTemplate;



      @Test
       public void findAllCustomers() throws Exception {
         ResponseEntity<List<Customer>> responseEntity = restTemplate.exchange(
            "/Customer", HttpMethod.GET, null,
            new ParameterizedTypeReference<List<Customer>>() {
            });

        List<Customer> list = responseEntity.getBody();
        Assert.assertEquals(list.size(), 0);
       }

}
