我的问题有点复杂,我会尽量清楚地解释。为此,我做了一个简单的项目。
我正在使用Swagger代码生成器从Swagger文件生成Java类。 在Swagger文件中,一个定义正在使用additionalProperties。
MyRequestBody:
type: object
properties:
property1:
type: string
property2:
type: string
additionalProperties:
type: object
生成的Java类:
/*
* Chatbot api
* Api for chatbot interface.
*
* OpenAPI spec version: 1.0
*
*
* NOTE: This class is auto generated by the swagger code generator program.
* https://github.com/swagger-api/swagger-codegen.git
* Do not edit the class manually.
*/
package lu.post.models.api.test;

@javax.annotation.Generated(value = "lu.post.codegen.ApiplaylibGenerator")
@JsonIgnoreProperties(ignoreUnknown = true)
@JsonInclude(JsonInclude.Include.NON_NULL)
@XmlRootElement(name="MyRequestBody")
@XmlAccessorType(XmlAccessType.FIELD)
public class MyRequestBody extends HashMap<String, Object> {
@JsonProperty("property1")
@XmlElement(name="property1")
private String property1 = null;
@JsonProperty("property2")
@XmlElement(name="property2")
private String property2 = null;
public MyRequestBody property1(String property1) {
this.property1 = property1;
return this;
}
/**
* Get property1
* @return property1
**/
@ApiModelProperty(example = "null", value = "")
public String getProperty1() {
return property1;
}
public void setProperty1(String property1) {
this.property1 = property1;
}
public MyRequestBody property2(String property2) {
this.property2 = property2;
return this;
}
/**
* Get property2
* @return property2
**/
@ApiModelProperty(example = "null", value = "")
public String getProperty2() {
return property2;
}
public void setProperty2(String property2) {
this.property2 = property2;
}
@Override
public boolean equals(java.lang.Object o) {
if (this == o) {
return true;
}
if (o == null || !(o instanceof MyRequestBody)) {
return false;
}
MyRequestBody myRequestBody = (MyRequestBody) o;
return Objects.equals(this.property1, myRequestBody.property1) &&
Objects.equals(this.property2, myRequestBody.property2) &&
super.equals(o);
}
@Override
public int hashCode() {
return Objects.hash(property1, property2, super.hashCode());
}
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append("class MyRequestBody {\n");
sb.append(" ").append(toIndentedString(super.toString())).append("\n");
sb.append(" property1: ").append(toIndentedString(property1)).append("\n");
sb.append(" property2: ").append(toIndentedString(property2)).append("\n");
sb.append("}");
return sb.toString();
}
/**
* Convert the given object to string with each line indented by 4 spaces
* (except the first line).
*/
private String toIndentedString(java.lang.Object o) {
if (o == null) {
return "null";
}
return o.toString().replace("\n", "\n ");
}
}
如您所见,生成的类为additionalProperties扩展了HashMap。
目前为止,没有什么惊人之处。
该类已在play / java项目中使用,使用play库对json和pojo进行序列化/反序列化。
我创建了一个简单的路由和控制器,以执行POST / test并使用以下正文(与swagger定义匹配)
{
"property1": "p1",
"property2": "p2"
}
我的控制器如下:
public Result test() {
classLogger.debug("==================================");
classLogger.debug("START test()");
JsonNode bodyJsonNode = request().body().asJson();
MyRequestBody myRequestBody = Json.fromJson(bodyJsonNode, MyRequestBody.class);
classLogger.debug("myRequestBody : ");
classLogger.debug(myRequestBody.toString());
classLogger.debug("END test()");
classLogger.debug("==================================");
return ok();
}

property1: null
property2: null
}

2017-12-16 22:54:15,605[DEBUG][][][][ConversationController]==================================
对象字段“property1”和“property2”为空,因为字段名称和值被放在Map的键/值中。
有人知道解决这个问题的最佳方法吗?请注意: - 我无法修改Swagger定义(因为在我的实际项目中,它是由另一个公司提供的)。 - 我希望继续使用Swagger代码生成库。
提前致谢,
OBJECT_MAPPER.configOverride(MyClass.class).setFormat(JsonFormat.Value.forShape(JsonFormat.Shape.OBJECT));
