String str = commonClient.authorizedRequestBuilder(commonClient.webTarget
.path("/apps/get_current_version/default/"+appName+"/"+appName)
.queryParam("object_type", "app"))
.accept(MediaType.APPLICATION_JSON_TYPE)
.get()
.readEntity(String.class);
我得到了
str = {"versions": {"ap": "Not Set", "am": "topic-test-publisher-1.0.16", "il": "topic-test-publisher-1.0.16", "row": "topic-test-publisher-1.0.49"}, "provider": "gce"}
然后我更改为此代码
Version version = commonClient.authorizedRequestBuilder(commonClient.webTarget
.path("/apps/get_current_version/default/"+appName+"/"+appName)
.queryParam("object_type", "app"))
.accept(MediaType.APPLICATION_JSON_TYPE)
.get(ClientResponse.class)
.readEntity(new GenericType<Version>(){});
并得到例外:

其中:
@JsonIgnoreProperties(ignoreUnknown = true)
public class Version {
@JsonProperty("am")
public String am;
@JsonProperty("row")
public String row;
@Override
public String toString() {
return "VersionDto{" +
"am='" + am + '\'' +
", row='" + row + '\'' +
'}';
}
}
我如何以不同方式反序列化?
更新
我试过了:
与
public class Version {
public Map<String, String> versions;
public String provider;
// getters, setters, etc
}
和
Version version = commonClient.authorizedRequestBuilder(commonClient.webTarget
.path("/apps/get_current_version/gce/waze-prod/default/"+appName+"/"+appName)
.queryParam("object_type", "app"))
.accept(MediaType.APPLICATION_JSON_TYPE)
.get(ClientResponse.class)
.readEntity(Version.class);
但得到了同样的错误
答案 0 :(得分:2)
我想说对象Version
需要一个名为versions
的{{1}}类型的字段和另一个名为Map<String, String>
的类型为provider
的字段,而您可能不需要String
。
GenericType
然后
public class Version {
private Map<String, String> versions;
private String provider;
// getters, setters, etc
}
使用
进行测试Version version = commonClient.authorizedRequestBuilder(commonClient.webTarget)
// ...
.readEntity(Version.class);
version.getVersions().get("am"); // to get "am"
输出:&#34; topic-test-publisher-1.0.16&#34;
