spring.jackson.default-property-inclusion无效问题

yml文件配置如下：

spring:
  jackson:
    default-property-inclusion: non_null

按照网上的说法，password属性为null时jackson应该不会将其序列化，但是真实情况如下：

阅读文档发现：

Finally, if you opt out of the Spring Boot default MVC configuration by providing your own @EnableWebMvc configuration, you can take control completely and do everything manually by using getMessageConverters from WebMvcConfigurationSupport.

我并没有用@EnableWebMvc这个注解，只是写了一个配置类继承了WebMvcConfigurationSupport，如下：

@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {

	//修改静态资源路径
	@Override
	protected void addResourceHandlers(ResourceHandlerRegistry registry) {
		String dir = System.getProperty("user.dir");

		//System.out.println("项目当前路径："+dir);
		//构建路径
		File file=new File(dir+File.separatorChar+"uploadImage");
		if(!file.exists()){
			file.mkdir();
		}
		String resourceLocation=file.getAbsolutePath()+File.separatorChar;
		WebConfig.UPLOAD_IMAGE_PATH=resourceLocation;
		//System.out.println(resourceLocation+">>>>>>");
		registry.addResourceHandler("/ui/**")
				.addResourceLocations("file:"+resourceLocation);

		//由于使用的是继承WebMvcConfigurationSupport，所以所以的默认匹配设置要重写
		registry.addResourceHandler("/**")
				.addResourceLocations("classpath:/META-INF/resources/")
				.addResourceLocations("classpath:/resources/")
				.addResourceLocations("classpath:/static/")
				.addResourceLocations("classpath:/public/");
		super.addResourceHandlers(registry);
	}

}

点开WebMvcConfigurationSupport ，发现：

写了一个配置类继承了WebMvcConfigurationSupport原来包涵了@EnableWebMvc，那就只能用注解的方式配置了，如下：

@JsonInclude(JsonInclude.Include.NON_NULL)	//注解控制null不序列化
public class User {
    private Long id;
    private String username;
    private String password;
    private String name;
    private String nickname;
    private Integer sex;
    private String phone;
    private String email;
    private Date birthday;
    private String place;
    private String street;
}

配置完后成功了：
