spring boot连接mongodb报错

Question

刚开始学习mongodb，编写了一个简单的springboot程序连接mongo，使用如下配置可以正确连接到mongo：
spring.data.mongodb.host=10.159.14.19
spring.data.mongodb.port=9001
spring.data.mongodb.authentication-database=admin
spring.data.mongodb.database=esign
spring.data.mongodb.username=esign_write
spring.data.mongodb.password=NTc2OTQ1YjcwN2Z
但是使用下面的配置就会报错：
spring.data.mongodb.uri=mongodb://esign_write:NTc2OTQ1YjcwN2Z@10.159.14.19:9001/esign
spring.data.mongodb.authentication-database=admin
错误信息如下：
com.mongodb.MongoSecurityException:ExceptionauthenticatingMongoCredential{mechanism=null,userName='esign_write',source='esign',password=,mechanismProperties={}}

spring.data.mongodb.uri=mongodb://esign_write:NTc2OTQ1YjcwN2Z@10.159.14.19:9001/esignspring.data.mongodb.authentication-database=admin改成spring.data.mongodb.uri=mongodb://esign_write:NTc2OTQ1YjcwN2Z@10.159.14.19:9001/spring.data.mongodb.database=esignspring.data.mongodb.authentication-database=admin我也不知道为什么试了下可以
