java.lang.NoClassDefFoundError: 无法初始化类 io.netty.handler.ssl.JdkSslClientContext

分类：编程问答

如何解决java.lang.NoClassDefFoundError: 无法初始化类 io.netty.handler.ssl.JdkSslClientContext

我正在为通量流编写测试，当我运行测试时，我收到错误 java.lang.NoClassDefFoundError：无法初始化 class.io.netty.handler.ssl.JdkSslClientContext。但是当我检查 netty 包中的依赖项时，该类就在那里。这仅在运行测试时发生。下面是我的代码和堆栈跟踪

    @DisplayName("Test findAll Success")
    void findAllTest() throws Exception {
        Flux<LimitAmounts> limits = utilSevice.fetchAmounts();
        StepVerifier.create(limits)
                .expectNextCount(15)
                .expectComplete()
                .verify();
    }

这是我的数据库配置 bean

@Configuration
@Profile("test")
public class MyTestConfiguration extends AbstractR2dbcConfiguration{

    @Primary
    @Bean
    @Override
    public ConnectionFactory connectionFactory() {
        return MySqlConnectionFactory.from(MySqlConnectionConfiguration.builder()
                .host(System.getenv("DATABASE_HOST"))
                .port(3306)
                .user(System.getenv("DATABASE_USER"))
                .password(System.getenv("DATABASE_PASS"))
                .sslMode(SslMode.DISABLED)
                .build());
    }
    
}
