spring-boot - Maven 中依赖项的嵌套异常 - java.io.FileNotFoundException: ServerPropertiesAutoConfiguration.class

Question

我有一个 Spring Boot 2.3.6 项目，Spring Cloud Hoxton.SR9 依赖“spring-cloud-starter-openfeign”。它还具有来自内部项目的 jar 依赖“通知”。这是Pom.xml：

主类：

package tests.test1;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Test1Application {

    public static void main(String[] args) {
        SpringApplication.run(Test1Application.class, args);
    }

}

我的问题来自依赖：

    <dependency>
        <groupId>t.tu</groupId>
        <artifactId>notificli</artifactId>
        <version>1.18.0.14</version>
    </dependency>

这是一个罐子：

• Spring Boot 1.5.11.RELEASE
• Spring-cloud-starter-feign 1.3.5.RELEASE

在编译时一切都很好，但在运行时抛出异常：

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [tests.test1.Test1Application]; nested exception is java.io.FileNotFoundException: class path resource [org/springframework/boot/autoconfigure/web/ServerPropertiesAutoConfiguration.class] cannot be opened because it does not exist

找不到此类ServerPropertiesAutoConfiguration.class，因为它需要 Spring Boot 1.x 中的“spring-boot-autoconfigure”依赖项。在 Spring Boot 2.x 类中不存在。

好的。如果我像这样降级 spring-boot-autoconfigure ：

    <dependencyManagement>
        <dependencies>
            ...
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-autoconfigure</artifactId>
                <version>1.5.11.RELEASE</version>
            </dependency>
            ...    
        </dependencies>
    </dependencyManagement>

我还有另一个例外：

java.lang.NoClassDefFoundError: org/springframework/boot/bind/RelaxedPropertyResolver

什么意味着我使用来自不同 Spring Boot（1.5 和 2.x）的依赖项

好的。再试一次。不要降级“spring-boot-autoconfigure”，但要从棘手的依赖项中排除“spring-cloud-starter-feign”，如下所示：

    <dependency>
        <groupId>t.tu</groupId>
        <artifactId>notificli</artifactId>
        <version>1.18.0.14</version>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-feign</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

而且我还有另一个例外：

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [tests.test1.Test1Application]; nested exception is java.io.FileNotFoundException: class path resource [org/springframework/cloud/netflix/feign/FeignAutoConfiguration.class] cannot be opened because it does not exist

找不到FeignAutoConfiguration.class，因为需要 spring-cloud-netflix-core 1.4.4.RELEASE 及以下版本。

如果我添加此依赖项，我会从帖子的开头返回异常：找不到ServerPropertiesAutoConfiguration.class 。

怎么处理？感谢您的关注。
