Spring Boot 2.7.3部署至WildFly 10.0.0时异常求助

我被这个问题折腾7天了，求各位帮忙。我的操作步骤：

• 通过start.spring.io创建简单Spring Boot应用
• 创建Rest Controller
• 安装WildFly，创建用户并启动管理控制台
• 执行mvn clean install生成war包并部署至WildFly控制台

以下是我的pom.xml配置：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.7.3</version>
    <relativePath/> <!-- lookup parent from repository -->

执行mvn clean install部署时出现以下错误：

1. 无法执行org.wildfly.plugins:wildfly-maven-plugin:2.0.2.Final:deploy (default)任务
2. 连接WildFly管理端口失败
3. 连接被拒绝：连接

排查与解决方法 #

1. 确认WildFly服务状态 #

• 检查WildFly是否正常启动，访问http://127.0.0.1:9990，能打开管理页面说明端口正常监听
• 若页面无法访问，重启WildFly服务，查看启动日志是否有异常

2. 核对用户配置 #

• 替换pom.xml中deploy.wildfly.username和deploy.wildfly.password的占位符，改为实际创建的WildFly管理用户名和密码
• 确保该用户拥有admin或deployer角色，可通过WildFly管理控制台的用户管理界面确认

3. 升级Maven插件 #

WildFly Maven插件2.0.2.Final版本较旧，与Spring Boot 2.7.x兼容性不佳，建议升级到最新稳定版，修改插件配置：

<plugin>
    <groupId>org.wildfly.plugins</groupId>
    <artifactId>wildfly-maven-plugin</artifactId>
    <version>3.0.2.Final</version>
    <!-- 其余配置保持不变 -->
</plugin>

4. 检查端口与防火墙 #

• 用netstat -ano | findstr :9990（Windows）或lsof -i :9990（Linux）检查9990端口是否被其他进程占用，若占用则停止对应进程或修改WildFly管理端口
• 关闭本地防火墙或添加9990端口的允许规则

5. 修正Spring Boot启动类 #

确保Spring Boot主类继承SpringBootServletInitializer，否则WAR包无法在WildFly中正确加载：

@SpringBootApplication
public class WarehouseConnectionApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(WarehouseConnectionApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(WarehouseConnectionApplication.class, args);
    }
}
