我已将我的Web应用程序上传到Heroku,我有一个名为“MongoLab”的插件。我将MongoLab的凭据放入我的Spring XML文件中,当我运行它时,我收到一个错误:
{"message":"Failed to authenticate to database [heroku_c82w85xw], username = [heroku_c82w85xw], password = [k************************c]","code":"org.springframework.data.mongodb.CannotGetMongoDbConnectionException
所以我还制作了一个包含凭据的Java配置文件,但我仍然得到同样的错误。我已经尝试了几个星期,但我仍然得到同样的错误。以下是我的Spring XML和Java配置文件。
Spring XML文件:
<mongo:mongo id="mongo" host="ds055575.mongolab.com" port="55575"/>
<mongo:db-factory
id="mongoDbFactory"
host="ds055575.mongolab.com"
port="55575"
username="heroku_c82w85xw"
password="XXX"
dbname="heroku_c82w85xw"
mongo-ref="mongo"/>
<bean id="anotherMongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
</bean>
<bean id="userDaoImpl" class="service.UserDaoImpl">
<constructor-arg name="mongoOps" ref="anotherMongoTemplate" />
</bean>
<bean id="userService" class="service.UserService">
<property name="userDaoImpl" ref="userDaoImpl" />
</bean>
Java配置文件:
@Configuration
public class JavaConfig {
public MongoClient getDB() {
String uri = "mongodb://heroku_c82w85xw:XXX"
+ "@ds055575.mongolab.com:55575/heroku_c82w85xw?authMechanism=SCRAM-SHA-1";
MongoClientURI mongoURI = new MongoClientURI(uri);
MongoClient client = null;
try {
client = new MongoClient(mongoURI);
} catch (Exception e) {
e.printStackTrace();
}
return client;
}
}
有人可以帮我解决这个错误吗?提前谢谢。
答案 0 :(得分:0)
您应该从MongoLab为您设置的环境变量中提取URI,而不是对URI进行硬编码。这是一个例子:
String uri = System.getenv("MONGOLAB_URI");
MongoClientURI uri = new MongoClientURI(uri);
MongoClient client = new MongoClient(uri);
DB db = client.getDB(uri.getDatabase());
这就是MongoLab推荐的documentation。
