由于springfox-swagger2的实现的问题，程序只能配置为按照英文字母排序。不过我们可以通过编写插件实现字段按类变量定义顺序排序。具体插件代码为

import static springfox.documentation.schema.Annotations.findPropertyAnnotation;

import static springfox.documentation.swagger.schema.ApiModelProperties.findApiModePropertyAnnotation;

import java.lang.reflect.Field;

import org.apache.commons.lang3.ArrayUtils;

import org.apache.commons.logging.Log;

import org.apache.commons.logging.LogFactory;

import org.springframework.stereotype.Component;

import com.fasterxml.jackson.databind.introspect.AnnotatedField;

import com.fasterxml.jackson.databind.introspect.BeanPropertyDefinition;

import com.google.common.base.Optional;

import io.swagger.annotations.ApiModelProperty;

import springfox.documentation.spi.DocumentationType;

import springfox.documentation.spi.schema.ModelPropertyBuilderPlugin;

import springfox.documentation.spi.schema.contexts.ModelPropertyContext;

import springfox.documentation.swagger.common.SwaggerPluginSupport;

@Component

public class CustomApiModelPropertyPositionBuilder implements ModelPropertyBuilderPlugin {

private Log log = LogFactory.getLog(getClass());

@Override

public boolean supports(DocumentationType delimiter) {

return SwaggerPluginSupport.pluginDoesApply(delimiter);

@Override

public void apply(ModelPropertyContext context) {

Optional<BeanPropertyDefinition> beanPropertyDefinitionOpt = context.getBeanPropertyDefinition();

Optional<ApiModelProperty> annotation = Optional.absent();

if (context.getAnnotatedElement().isPresent()) {

annotation = annotation.or(findApiModePropertyAnnotation(context.getAnnotatedElement().get()));

if (context.getBeanPropertyDefinition().isPresent()) {

annotation = annotation.or(findPropertyAnnotation(context.getBeanPropertyDefinition().get(), ApiModelProperty.class));

if (beanPropertyDefinitionOpt.isPresent()) {

BeanPropertyDefinition beanPropertyDefinition = beanPropertyDefinitionOpt.get();

if (annotation.isPresent() && annotation.get().position() != 0) {

return;

AnnotatedField field = beanPropertyDefinition.getField();

Class<?> clazz = field.getDeclaringClass();

Field[] declaredFields = clazz.getDeclaredFields();

Field declaredField;

try {

declaredField = clazz.getDeclaredField(field.getName());

} catch (NoSuchFieldException | SecurityException e) {

log.error("", e);

return;

int indexOf = ArrayUtils.indexOf(declaredFields, declaredField);

if (indexOf != -1) {
