Spring错误——Junit测试——java.net.BindException: Address already in use: bind

背景

• 项目目录结构如下
  • 

• • 其中application-dev.yml为开发环境，application-prod.yml为生产环境，application-test.yml为测试环境
  • 每个环境使用的数据库不同，测试时使用test环境进行单元测试。
• 开发项目使用Junit批量进行单元测试时，报错：java.net.BindException: Address already in use: bind,如下
  • 

原因

• 两个测试类使用的环境不同，一个使用的是dev环境测试，一个使用的是test环境测试，代码如下
  • ElecInvalidOrderTest测试类

    • import java.sql.SQLException;
      
      import static org.assertj.core.api.Assertions.assertThat;
      
      /**
       * @author jingguoliang
       * @Description: 失效电费订单
       * @date 2020/4/14
       */
      @RunWith(SpringRunner.class)
      @SpringBootTest
      @Transactional(rollbackFor = Exception.class, isolation = Isolation.READ_UNCOMMITTED)
      @ActiveProfiles(value = "dev")
      public class ElecInvalidOrderTest {
      
          private static final Logger logger = LoggerFactory.getLogger( ElecInvalidOrderTest.class );
         
      
          @Before
          public void setUp() throws Exception {
      
              initializeDbData();//初始化数据
          }
          public void initializeDbData() throws SQLException, IOException {
      
          }
      
          @After
          public void tearDown() throws Exception {
      
        
          }
      
          //失效电费订单1
          @Test
          public void orderSuperviser1() {
              //调用业务服务
              logger.info("BizType.elecorder_invalid is start");
      
          }

  • ElecWillInvalidOrderTest测试类

• 每一个环境在测试开始时都会使用启用一个Adress，所以会出现地址已经占用的问题

解决办法

• 如果批量测试，只能把测试环境进行统一，都改成dev或者test
