我尝试使用./shutdown.shtomcat /bin目录关闭tomcat .但发现服务器没有正常关闭.因此我无法重启
我的tomcat正在端口上运行8080.

我想杀死运行的tomcat进程8080.我首先想要在特定端口(8080)上运行进程列表,以便选择要杀死的进程.

我在Spring Tool Suite IDE中使用嵌入式Tomcat服务器。我的问题是，当我运行我的项目时，出现以下错误，

***************************
APPLICATION FAILED TO START
***************************

Description:

The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.

有一些类似的问题，但是没有一个答案对我不起作用。

我尝试在 Spring Boot 项目中设置一个 Mongo DB。我在 application.yml 中设置了一个 uri：

spring:
  data:
    mongodb:
      uri: mongodb://user:pass@localhost:27017/mydbname

但是应用程序无法从存储库读取数据并出现错误：

Attempt to switch database target during SASL authentication.

发生错误的行（kotlin）：

val emails = emailRepository.findAllByStatus(READY_TO_SEND)

在哪里

interface EmailRepository : MongoRepository<Email, String> {
    fun findAllByStatus(status: EmailStatus) : Collection<Email>
}

和

data class Email(
    @Id
    @get:JsonIgnore
    var id: String? = null,
    @get:NotNull
    val from: MailActor,
    @get:NotEmpty
    val to: Collection<MailActor>,
    @get:NotEmpty
    val subject: String,
    @get:NotEmpty
    val htmlText: String,
    val attachments: Collection<Attachment> = listOf(),
    val cc: Collection<MailActor> = listOf(),
    val bcc: …

我有一个与mongo db集成的java应用程序.我碰巧有3个mongo db主机(都有相同的端口),并且必须使用除我的应用程序使用的db之外的单独数据库进行身份验证.例如:"admin"是身份验证数据库名称,"contenttest"是我的应用程序要连接的db.我也有凭据(用户名和密码).我尝试使用以下uri进行连接,但它在spring boot应用程序中无效.

application.properties

spring.data.mongodb.authentication-database=admin
spring.data.mongodb.uri = mongodb://content_rw:<secret password>@a.mongo.db:27017,b.mongo.db:27017,c.mongo.db:27017/contenttest?wtimeoutMS=300&connectTimeoutMS=500&socketTimeoutMS=200

我收到错误,说明以下错误日志的身份验证失败.
