com.sun.jersey.api.client.ClientHandlerException：java.net.ConnectException：连接被拒绝：在 Spring 启动时连接
com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused: connect in Spring Boot
我正在从 http://www.javainuse.com/spring/spring-cloud-netflix-zuul-tutorial 开发代码，还没有自定义。我不断收到下面提到的错误。因此，为避免此错误，我在 application.properties 文件中添加了以下内容。
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
eureka.client.server.waitTimeInMsWhenSyncEmpty=0
在我添加上述属性的那一刻，我没有收到任何错误。
以下错误供参考-

所以我的问题是，我们如何避免 post 中提到的第一个错误？请指导。
EurekaServer是运行吗？
我遇到了同样的问题，问题是我没有 运行 Eureka 服务器。
在 运行 Eureka Server 之后它开始正常工作。
获取异常连接被拒绝。这意味着服务器端口号已经在后台运行。是否在后台检查您的服务器端口号 运行。
遵循这个流程：
后台可能运行相同的端口号，查看windows中的以下命令并杀死。
转到命令提示符->运行 下面的命令，
Find open running ports:
C:\WINDOWS\system32>netstat -ano | findstr :Port number
Example: netstat -ano | findstr :8761
kill ports based on PID(process ID)
C:\WINDOWS\system32>taskkill /PID PIDNumber /F
Example: taskkill /PID 3740 /F
使用上述命令杀死所有 运行 服务并设置端口号并在 application.properties 文件中写入以下代码。
server.port=8761
#set port number
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetchRegistry=false
eureka.client.server.waitTimeInMsWhenSyncEmpty=0
只需编辑以上几行。工作正常。
问题可能是您没有为 Eureka 服务器指定正确的端口。如果您不指定端口，它将尝试使用 默认端口 8080，这将导致错误。在您的 application.properties 文件中使用下面提到的配置。 8761 是 eureka 服务器的默认端口
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
还要确保你的注释主要 class 如下
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
为此，我刚刚使用 setting.xml 文件解决了这个问题，该文件应该位于存储库文件夹下方的 .m2 文件夹中。
setting.xml file in m2 reposotory
1) 您只需在简单的记事本中创建此文件，然后在其中输入下面的代码
<?xml version="1.0" encoding="UTF-8"?>
<settings
xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<pluginGroups/>
<proxies>
<!-- Proxy for HTTP -->
<proxy>
<id>optional</id>
<active>true</active>
<protocol>http</protocol>
<username>proxyuser</username>
<password>proxypass</password>
<host>172.25.33.10</host>
<port>8080</port>
<nonProxyHosts>local.net</nonProxyHosts>
</proxy>
<!-- Proxy for HTTPS -->
<proxy>
<id>optional</id>
<active>true</active>
<protocol>https</protocol>
<username>proxyuser</username>
<password>proxypass</password>
<host>172.25.33.10</host>
<port>8080</port>
<nonProxyHosts>local.net</nonProxyHosts>
</proxy>
</proxies>
<servers/>
<mirrors/>
<profiles/>
</settings>
然后将此文件另存为 setting.xml
并将其放入存储库下方的 .m2 文件夹中
2) 比转到 IDE（我用过 ECLIPSE），windows->preference-user setting->brows file path to setting.xml (C:\Users\himanshun.m2\settings.xml) -> 点击更新设置 -> 应用并关闭
因为你配置了属性查找要注册微服务的服务器。
## eureka.client.eureka-server-port=8761 // on which port server is running
所以先启动eureka server 然后它会注册eureka server
在application.properties文件中添加如下配置即可
#Eureka's default port
server.port=8761
对我来说，我的 settings.xml 中定义的代理服务器导致了这个问题。
在 settings.xml 位于 Windows C:/Users/[用户名]/.m2/ 目录中，
确保删除或注释掉任何可能导致连接问题的专用 <servers>、<proxies>、<mirrors> 或 <profiles>。
我正在从 http://www.javainuse.com/spring/spring-cloud-netflix-zuul-tutorial 开发代码，还没有自定义。我不断收到下面提到的错误。因此，为避免此错误，我在 application.properties 文件中添加了以下内容。
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
eureka.client.server.waitTimeInMsWhenSyncEmpty=0
在我添加上述属性的那一刻，我没有收到任何错误。
以下错误供参考-

所以我的问题是，我们如何避免 post 中提到的第一个错误？请指导。
EurekaServer是运行吗？
我遇到了同样的问题，问题是我没有 运行 Eureka 服务器。 在 运行 Eureka Server 之后它开始正常工作。
获取异常连接被拒绝。这意味着服务器端口号已经在后台运行。是否在后台检查您的服务器端口号 运行。
遵循这个流程：
后台可能运行相同的端口号，查看windows中的以下命令并杀死。 转到命令提示符->运行 下面的命令，
Find open running ports:
C:\WINDOWS\system32>netstat -ano | findstr :Port number
Example: netstat -ano | findstr :8761
kill ports based on PID(process ID)
C:\WINDOWS\system32>taskkill /PID PIDNumber /F
Example: taskkill /PID 3740 /F
使用上述命令杀死所有 运行 服务并设置端口号并在 application.properties 文件中写入以下代码。
server.port=8761
#set port number
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetchRegistry=false
eureka.client.server.waitTimeInMsWhenSyncEmpty=0
只需编辑以上几行。工作正常。
问题可能是您没有为 Eureka 服务器指定正确的端口。如果您不指定端口，它将尝试使用 默认端口 8080，这将导致错误。在您的 application.properties 文件中使用下面提到的配置。 8761 是 eureka 服务器的默认端口
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
还要确保你的注释主要 class 如下
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
为此，我刚刚使用 setting.xml 文件解决了这个问题，该文件应该位于存储库文件夹下方的 .m2 文件夹中。 setting.xml file in m2 reposotory
1) 您只需在简单的记事本中创建此文件，然后在其中输入下面的代码
<?xml version="1.0" encoding="UTF-8"?>
<settings
xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<pluginGroups/>
<proxies>
<!-- Proxy for HTTP -->
<proxy>
<id>optional</id>
<active>true</active>
<protocol>http</protocol>
<username>proxyuser</username>
<password>proxypass</password>
<host>172.25.33.10</host>
<port>8080</port>
<nonProxyHosts>local.net</nonProxyHosts>
</proxy>
<!-- Proxy for HTTPS -->
<proxy>
<id>optional</id>
<active>true</active>
<protocol>https</protocol>
<username>proxyuser</username>
<password>proxypass</password>
<host>172.25.33.10</host>
<port>8080</port>
<nonProxyHosts>local.net</nonProxyHosts>
</proxy>
</proxies>
<servers/>
<mirrors/>
<profiles/>
</settings>
然后将此文件另存为 setting.xml
并将其放入存储库下方的 .m2 文件夹中
2) 比转到 IDE（我用过 ECLIPSE），windows->preference-user setting->brows file path to setting.xml (C:\Users\himanshun.m2\settings.xml) -> 点击更新设置 -> 应用并关闭
因为你配置了属性查找要注册微服务的服务器。
## eureka.client.eureka-server-port=8761 // on which port server is running
所以先启动eureka server 然后它会注册eureka server
在application.properties文件中添加如下配置即可
#Eureka's default port
server.port=8761
对我来说，我的 settings.xml 中定义的代理服务器导致了这个问题。
在 settings.xml 位于 Windows C:/Users/[用户名]/.m2/ 目录中，
确保删除或注释掉任何可能导致连接问题的专用 <servers>、<proxies>、<mirrors> 或 <profiles>。
