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;

}
