报错原因

WebSocket需要依赖Tomcat等容器启动

解决办法

在SpringBootTest后加上“webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT”，意思是创建Web应用程序上下文。

完整示例参考以下代码：

package org.jeecg;import lombok.extern.slf4j.Slf4j;
import org.jeecg.modules.info.cache.DataCache;
import org.jeecg.modules.info.service.IWrSeasonBService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;/*** @Description: 数据缓存测试类* @author: 大强* @date: 2021年2月3日*/
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@Slf4j
public class DataCacheTest {@AutowiredDataCache dataCahche;@AutowiredIWrSeasonBService iWrSeasonBService;/*** 灌季缓存测试*/@Testpublic void irrSeasonTest() {log.info("========================");log.info("灌季缓存测试");log.info("灌季名称:" + "春灌");String str = dataCahche.getStartEndDateBySeasonNm("春灌");// assertEquals("2021-03-01,2021-04-30", str);String[] arr = str.split(",");if (arr != null && !arr.equals("null")) {log.info("开始日期、结束日期:" + arr[0] + "," + arr[1]);} else {log.info("记录缓存不存在");}log.info("========================");}}
