Spring Boot整合WebSocket時運行測試類會報錯

Spring Boot整合WebSocket時運行測試類會報錯

問題

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class DemoApplicationTests {
    @Test
    void contextLoads() {
        System.out.println("整合WebSocket時，運行測試類會報錯");
    }
}

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘serverEndpointExporter’ defined in class path resource [com/example/demo/config/WebSocketConfig.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: javax.websocket.server.ServerContainer not available

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘serverEndpointExporter’ defined in class path resource [com/example/demo/config/WebSocketConfig.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: javax.websocket.server.ServerContainer not available

解決方法

修改@SpringBootTest，其中DemoApplication爲啓動類

@SpringBootTest(classes = DemoApplication.class, webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
