我试图理解之间的差异BeanFactoryPostProcessor和BeanPostProcessor.

我理解它BeanFactoryPostProcessor在bean定义上运行,即在bean实例创建之前,它会被执行并BeanPostProcessor在实例化bean并调用生命周期事件后执行.

这是否意味着BeanFactoryPostProcessor不是BeanPostProcessorSpring生命周期事件的一部分,因为它是在实例化之前调用的,而Spring是Spring生命周期事件的一部分吗？请核实我的理解是否正确.

我有一些问题XmlMapper在我的一个Spring Boot项目中自动装配默认的Jackson .我已经创建了一个简单的示例项目来说明这一点.

我在这里做的大致基于这个:

主要课程:

@SpringBootApplication
public class DemoApplication {

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

演示POJO,没有指定@XmlRootElement,所以它不会使用JAXB:

@JsonInclude(Include.NON_NULL)
public class Demo {
    private String stringProperty;
    private int intProperty;
    public String getStringProperty() {
        return stringProperty;
    }
    public void setStringProperty(String stringProperty) {
        this.stringProperty …
