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) {
context.getBuilder().position(indexOf);
}
}
}
}
但手熟尔
如果出现问题,应为版本问题。自己研究如何在当前版本写一个插件实现。
