Question

我们在Spring启动应用程序（微服务）中使用Couchbase DB，它在PCF和应用程序崩溃启动期间产生NoSuchMethodError

使用的Couchbase SDK是2.5.8

            <dependency>
                <groupId>com.couchbase.client</groupId>
                <artifactId>java-client</artifactId>
                <version>2.5.8</version>
            </dependency>

并且RxJava版本是1.1.10。

使用以下代码

创建CouchbaseEnvironment

            CouchbaseEnvironment env = DefaultCouchbaseEnvironment.builder()
            .sslEnabled(true).bootstrapHttpSslPort(18091)
            .sslKeystoreFile(Preconditions.checkNotNull(environment.getProperty("couchbase.ssl.keystore")))
            .sslKeystorePassword(Preconditions.checkNotNull(environment.getProperty("couchbase.ssl.keystore.password")))
            .connectTimeout(50000)
            .kvTimeout(50000)
            .build();

我们得到的例外如下

尝试使用Spring引导中可用的依赖项，但随后获得Time Out异常。

            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-data-couchbase</artifactId>
            </dependency>

Couchbase存储桶在PCF中创建为服务，并在服务中进行绑定。

            [org/springframework/boot/autoconfigure/couchbase/CouchbaseAutoConfiguration$CouchbaseConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.couchbase.client.java.Bucket]: Factory method 'couchbaseClient' threw exception; nested exception is java.lang.RuntimeException: java.util.concurrent.TimeoutException

非常感谢任何帮助。

Answer 1

您可能还需要将core-io升级到1.5.6或更高版本。

<dependency>
    <groupId>com.couchbase.client</groupId>
    <artifactId>core-io</artifactId>
    <version>1.5.8</version>
</dependency>

NoSuchMethodError因为this change已经提交而被抛出。

该问题是由于Spring Cloud依赖性所致。我们组织的PCF已升级到最新版本的Spring Cloud Dependencies，一旦我升级到最新版本，它就可以正常工作

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.2.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <spring-cloud.version>Finchley.RC2</spring-cloud.version>
    </properties>

我以前使用的是以下版本

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.8.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <spring-cloud.version>Dalston.SR4</spring-cloud.version>
    </properties>

一旦我更新了这些依赖项，它便开始工作。
