Question

我正在尝试使用以下配置为Apache Flume配置Solace源：

jndi.properties

Solace_JMS_VPN=VPN name
Solace_JMS_SSL_TrustStore=<path to trustore file>
Solace_JMS_SSL_TrustStorePassword=truststore password

相关的Flume配置

a1.sources.recieveFromJMS.type = jms
a1.sources.recieveFromJMS.channels = c1
a1.sources.recieveFromJMS.initialContextFactory = com.solacesystems.jndi.SolJNDIInitialContextFactory
a1.sources.recieveFromJMS.connectionFactory = connectionFactoryname
a1.sources.recieveFromJMS.providerURL = smfs://username:pass%40word@dns:port
a1.sources.recieveFromJMS.destinationName = queueName
a1.sources.recieveFromJMS.destinationType = QUEUE
a1.sources.recieveFromJMS.batchSize=100

当Source如下启动时，我遇到了异常：

我已经验证了用户名和密码。密码有一个特殊字符（@），我已将其替换为％40。仍然出现相同的错误。感谢您的帮助或指导。

Answer 1

我发现了问题。根据给定的优先级，我提供的密码已被系统属性（java.naming.security.credentials）覆盖。我在JNDI属性文件中将用户名提供为java.naming.security.principal=username 并将密码作为系统属性设置为-Djava.naming.security.credentials=password，而将Flume和providerURL用作smfs://dns则启动，一切正常。

启动Flume的Solace源时输入了错误的用户名密码
