springboot 2.x相关配置

1、在配置文件中进行配置

#############指定项目中所有的日期类型返回json格式###########
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.serialization.write-dates-as-timestamps=false
############设置空值不返回################################
#spring.jackson.default-property-inclusion=non_null

##############设置文件上传大小############
spring.servlet.multipart.max-file-size = 1073741824
spring.servlet.multipart.max-request-size = 10737418240

2、注册拦截器需要实现WebMvcConfigurer

@Configuration
public class WebAppConfig implements WebMvcConfigurer {
    @Autowired
    private HeaderInterceptor headerInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(headerInterceptor).addPathPatterns("/**");
    }

}
