使用mongodb在新的jhipster應用程序中進行集成測試時出現異常

Question

當我創建新的jhipster應用並運行集成測試時，我會遇到以下異常：

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

解決方案是更改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();
}

看來您的JAR文件已損壞，是否嘗試刪除Maven存儲庫並重新安裝庫？
