当前使用版本(必填,否则不予处理)

 <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-spring-boot3-starter</artifactId>
        <version>3.5.4.1</version>
    </dependency>

   <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>dynamic-datasource-spring-boot3-starter</artifactId>
        <version>4.2.0</version>
    </dependency>

该问题是如何引起的？(确定最新版也有问题再提!!!)

使用最新的springboot3.2.0版本，JAVA21

重现步骤(如果有就写完整)

springboot启动就报错

需要升级mybatis-spring这个依赖到3.0.3，希望官方快点升级。

同样遇到这个问题了,得升级mybatis-spring为3.0.3才行。或者springboot降级为3.1.x以下 springboot3.2.0重写了这个类FactoryBeanRegistrySupport的getTypeForFactoryBeanFromAttributes方法

ResolvableType getTypeForFactoryBeanFromAttributes(AttributeAccessor attributes) { Object attribute = attributes.getAttribute(FactoryBean.OBJECT_TYPE_ATTRIBUTE); if (attribute == null) { return ResolvableType.NONE; } if (attribute instanceof ResolvableType resolvableType) { return resolvableType; } if (attribute instanceof Class<?> clazz) { return ResolvableType.forClass(clazz); } throw new IllegalArgumentException("Invalid value type for attribute '" + FactoryBean.OBJECT_TYPE_ATTRIBUTE + "': " + attribute.getClass().getName()); }

springboot3.1.5：

ResolvableType getTypeForFactoryBeanFromAttributes(AttributeAccessor attributes) { Object attribute = attributes.getAttribute(FactoryBean.OBJECT_TYPE_ATTRIBUTE); if (attribute instanceof ResolvableType resolvableType) { return resolvableType; } if (attribute instanceof Class<?> clazz) { return ResolvableType.forClass(clazz); } return ResolvableType.NONE; }

之前的版本获取的attribute是个String类型,但是可以返回ResolvableType.NONE,就没报错了
