Spring 启动 optaplanner 自动装配问题

Question

你好，这是我第一次在 spring 引导中使用 optaplanner 库，所以我在我的 pom.xml 中输入了我的依赖项，当我运行它时，我收到一条错误消息jar 生成的某些类无法注入以下是我的 pom.xml :

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema- 
   instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-

            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

但是当我尝试运行我的项目时，我得到了这个错误

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 
'solverManager' defined in class path resource 
[org/optaplanner/spring/boot/autoconfigure/OptaPlannerAutoConfiguration.class]: Unsatisfied 
dependency expressed through method 'solverManager' parameter 0; nested exception is 
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'solverConfig' 
defined in class path resource

感谢任何帮助。
