目前，我在使用 MongoDB 进行 Spring 身份验证时遇到问题。我的 Spring XML 配置文件中有以下声明：

Spring Boot 导入 Spring XML 文件： 我在我的“spring boot 主类”中导入下面的“spring configuration XML”文件，如下所示：

@SpringBootApplication
@ImportResource("classpath:META-INF/spring/Myapp-AppContext.xml")
public class MySpringBootApplication extends SpringBootServletInitializer {
.... //Some Code goes here
}

弹簧配置 XML 文件：

<mongo:mongo-client id="mongo" host="localhost" port="27017" credentials="admin:mypass@mydb">       
    <mongo:client-options description="Connection to DB"/>
</mongo:mongo-client>

<mongo:db-factory id="myConnection" mongo-ref="mongo" dbname="mydb"/>
<mongo:template id="myOps" db-factory-ref="myConnection"/>
<mongo:repositories
    base-package="com.test.app" mongo-template-ref="myOps" />

在将其作为“Spring Boot 应用程序”运行时，出现以下错误：

例外：

原因：org.springframework.beans.ConversionNotSupportedException：无法将类型“java.lang.String”的属性值转换为属性“凭据”所需的类型“com.mongodb.MongoCredential []”；嵌套异常是 java.lang.IllegalStateException：无法将类型“java.lang.String”的值转换为属性“credentials [0]”所需的类型“com.mongodb.MongoCredential”：找不到匹配的编辑器或转换策略 在 org.springframework.beans.AbstractNestablePropertyAccessor.convertIfNecessary(AbstractNestablePropertyAccessor.java:590) ~[spring-beans-5.0.6.RELEASE.jar:5.0.6.RELEASE] 在 org.springframework.beans.AbstractNestablePropertyAccessor.convertForProperty(AbstractNestablePropertyAccessor. java:604) ~[spring-beans-5.0.6.RELEASE.jar:5.0.6.RELEASE] at org.springframework.beans.BeanWrapperImpl.convertForProperty(BeanWrapperImpl.java:219) ~[spring-beans-5.0.6 .RELEASE.jar:5.0.6.RELEASE] 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.convertForProperty(AbstractAutowireCapableBeanFactory.java:1658) ~[spring-beans-5.0.6.RELEASE.jar:5.0.6。发布] 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1614）~[spring-beans-5.0.6.RELEASE.jar:5.0.6.RELEASE]在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean（AbstractAutowireCapableBeanFactory.java:1361）~[spring-beans-5.0 .6.RELEASE.jar:5.0.6.RELEASE] 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:578) ~[spring-beans-5.0.6.RELEASE.jar:5.0. 6.RELEASE] ...省略了118个常用帧578）~[spring-beans-5.0.6.RELEASE.jar:5.0.6.RELEASE] ...省略了118个常用框架578）~[spring-beans-5.0.6.RELEASE.jar:5.0.6.RELEASE] ...省略了118个常用框架

异常原因：

根据我的理解，我认为“Spring-data-Mongodb” JAR 缺少一个“Converter”实现，它将“credentials”属性（它是一个字符串类型）转换为一个“com.mongodb.MongoCredential”数组。

请让我知道是否有另一个支持身份验证机制的“spring-data-mongodb”企业版或任何其他解决此问题的方法。

我的应用程序使用以下版本的软件：

  • 使用的 Spring Boot 版本：2.0.2.RELEASE
  • 使用的 Spring 版本：5.0.6.RELEASE
  • Spring Data MongoDB 版本：2.0.9.RELEASE
  • Mongo驱动版本：3.8.0
  • Mongo Java 驱动版本：3.8.0
  • Mongo Driver Core 版本：3.8.0（与 Mongo Java Driver JAR 交替使用，因为它们是相同的）
  • Mongo 社区服务器版本：3.6.5

我让它以不同的方式工作。在这里，最终的 Spring XML 文件配置如下所示：

<bean id="myMongoServers" class="java.util.ArrayList">
<constructor-arg>
    <list>
        <ref bean="myMongoServer" />
    </list>
</constructor-arg>
</bean>

<bean id="myMongoServer" class="com.mongodb.ServerAddress">
        <constructor-arg type="java.lang.String" name="host" value="localhost" />
        <constructor-arg type="int" name="port" value="27017" />
</bean>

<bean id="myMongoCredentials" class="java.util.ArrayList">
<constructor-arg>
    <list>
        <ref bean="myMongoCredential" />
    </list>
</constructor-arg>
</bean>

<bean id="myMongoCredential" class="com.mongodb.MongoCredential">
        <constructor-arg name="mechanism" value = "#{T(com.mongodb.AuthenticationMechanism).SCRAM_SHA_1}" />
        <constructor-arg type="java.lang.String" name="userName" value="admin" />
        <constructor-arg type="java.lang.String" name="source" value="mydb" />
        <constructor-arg type="char[]" name="password" value="mypass"/>
</bean>

<!-- MongoClient -->
<bean id="mongo" class="com.mongodb.MongoClient">
        <constructor-arg ref="myMongoServers" />
        <constructor-arg ref="myMongoCredentials"  />
</bean>

<mongo:db-factory id="myConnection" mongo-ref="mongo" dbname="mydb"/>

<mongo:template id="myOps" db-factory-ref="myConnection"/>

<mongo:repositories base-package="com.test.app" mongo-template-ref="myOps" />

此问题是由于将凭据传递给 mongo-driver 的方式发生了变化。有了这个，您需要提供 ServerAddress 和 Credentials（其中一部分是作为 Character[] 的密码）。

SCRAM-SHA-1 是用于对 MongoDB 进行身份验证的机制。如果需要，还有其他具有相似参数的不同身份验证方法。

如果您使用的是基于 Java 的配置，则可以参考以下代码段：

    @Bean
    public MongoDbFactory mongoDbFactory() {
        ServerAddress serverAddress = new ServerAddress(mongoHost, mongoPort);
        MongoCredential mongoCredential = MongoCredential.createScramSha1Credential(mongoUser, mongoDB, mongoPass.toCharArray());

        MongoClient mongoClient = new MongoClient(serverAddress, mongoCredential,
                new MongoClientOptions.Builder().build());
        MongoDbFactory dbFactory = new SimpleMongoDbFactory(mongoClient, mongoDB);
        return dbFactory;
    }

    @Bean
    public MongoTemplate mongoTemplate(@Autowired MongoDbFactory mongoDbFactory) {
        return new MongoTemplate(mongoDbFactory);
    }

参考这个： http://mongodb.github.io/mongo-java-driver/3.6/javadoc/?com/mongodb/ MongoCredential.html
