mongodb 的新 jhipster 应用程序集成测试期间出现异常

Question

当我创建新的 jhipster 应用程序和运行集成测试时，我遇到了这样的异常：

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.mongodb.Mongo]: Factory method 'mongo' threw exception; nested exception is de.flapdoodle.embed.process.exceptions.DistributionException: java.io.EOFException: Unexpected end of ZLIB input stream

Answer 1

您的 JAR 文件似乎已损坏，您是否尝试删除 Maven 存储库并重新安装这些库？

Answer 2

解决方案是更改 mongo spring bean 使用的 EmbeddedMongoBuilder 中的版本：

    @Bean
public Mongo mongo() throws IOException {
    System.setProperty("DB.TRACE","true");
    return new EmbeddedMongoBuilder()
            .version("2.6.10")
            .bindIp("127.0.0.1")
            .port(allocateRandomPort())
            .build();
}
