com.mongodb.MongoSocketOpenException：打开套接字异常（完全删除 mongodb 后）

Question

我在开发一半后得到了一个应用程序，我必须完成开发，但由于许可问题，我被要求删除 mongodb 并改用 couchdb。现在，我已经删除了代码中 mongodb 连接的所有实例，从 application.properties 中删除了 mongo 连接属性，但是当我启动 spring申请。

2022-01-21 15:58:14.043 INFO --- [localhost:27017] o.m.d.cluster : Exception in monitor thread while connecting to server localhost:27017 com.mongodb.MongoSocketOpenException: Exception opening socket at com.mongodb.internal.connection.SocketStream.open(SocketStream.java:70) at com.mongodb.internal.connection.InternalStreamConnection.open(InternalStreamConnection.java:180) at com.mongodb.internal.connection.DefaultServerMonitor$ServerMonitorRunnable.lookupServerDescription(DefaultServerMonitor.java:188) at com.mongodb.internal.connection.DefaultServerMonitor$ServerMonitorRunnable.run(DefaultServerMonitor.java:152) at java.lang.Thread.run(Thread.java:748) Caused by: java.net.ConnectException: Connection refused: connect at java.net.DualStackPlainSocketImpl.waitForConnect(Native Method) at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:85) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:607) at com.mongodb.internal.connection.SocketStreamHelper.initialize(SocketStreamHelper.java:107) at com.mongodb.internal.connection.SocketStream.initializeSocket(SocketStream.java:79) at com.mongodb.internal.connection.SocketStream.open(SocketStream.java:65) ... 4 more

我的 pom.xml 看起来像这样，我无法从中删除 mongo 依赖项，因为仍在使用 bson 文档 class.

这是我的 application.properties

spring.data.couchdb.password=hidden

spring.data.couchdb.uri=http://localhost:5984
# JWT configuration
jwt.secret = authsecret
jwt.expirationDateInMs=600000
jwt.refreshExpirationDateInMs=600000

运行应用程序没有问题，但需要删除此错误。任何帮助将不胜感激

您必须删除此依赖项

 <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-mongodb</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

默认情况下，spring 自动配置是 kicking-in 并尝试打开和创建连接。

或者另一种方法是从 spring 应用程序中排除自动配置，如下所示：

@SpringBootApplication(exclude = {
        MongoAutoConfiguration.class,
        MongoDataAutoConfiguration.class
})
public class SampleApplication{...}

我建议您更好地删除依赖项，因为您已决定从应用程序中删除 mongodb。
