本文分析了Spring框架中Bean创建失败的具体原因，特别是在定义Boss类时由于缺少office属性的setter和getter方法导致的问题。通过阅读本文，读者可以了解如何正确地在Spring中配置Bean属性。

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'boss' defined in class path resource [xiao/lei/entity/beans.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'office' of bean class [xiao.lei.entity.Boss]: Bean property 'office' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

错误原因是：Boss类中缺少属性的set/get方法
public class Boss {
    private Office office;
    @Override
    public String toString() {
        return "office:" + office;
    }

}
