方法context.getBean（name，user）的文档说

允许指定显式构造函数参数/工厂方法参数

但是无论我做什么（尝试一切），使用最合理的设置在初始化期间加载Bean时都会得到以下信息：

org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'fileValidator' defined in
PortletContext resource
[/WEB-INF/classes/context/customer-form-portlet.xml]: Unsatisfied
dependency expressed through constructor argument with index 0 of type
[com.liferay.portal.model.User]: Ambiguous factory method argument
types - did you specify the correct bean references as factory method
arguments?
    org.springframework.beans.factory.UnsatisfiedDependencyException:

<bean id="fileValidator" 
      class="cz.instance.transl.validation.file.FileValidator" 
      factory-method="createInstance" />

private FileValidator(User user) {
    this.user = user;
}

public static FileValidator createInstance(User user) {
    return new FileValidator(user);
}

注释说可以做到的，但是如果您在该bean的xml定义中指定构造函数参数，则失败。
