我正在尝试使用Retrofit 2.0和Jackson解析器，但它不起作用。它不会将值映射到模型。它给了我这个例外：
com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException：无法识别的字段“total_count”（类models.GitResult），未标记为可忽略（3个已知属性：“incompleteResults”，“items”，“totalcount”]）<登记/> at [Source：buffer（（buffer（okio.GzipSource@2235992）））。inputStream（）; line：1，column：21]（通过参考链：models.GitResult [“total_count”]）
但是我的模型和json响应中的键值是相同的。 这是模型：
private boolean incompleteResults;
private List<Item> items = new ArrayList<Item>();
private int totalcount;
json响应是这个

项目模型也正确完成。它适用于GsonConverterFactory，但不适用于JacksonFactory。
这是我的客户端设置：
private static GitApiInterface gitApiInterface ;
private static String baseUrl = "https://api.github.com" ;
public static GitApiInterface getClient() {
if (gitApiInterface == null) {
OkHttpClient okClient = new OkHttpClient();
okClient.interceptors().add(new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
Response response = chain.proceed(chain.request());
return response;
}
});
Retrofit client = new Retrofit.Builder()
.baseUrl(baseUrl)
.client(okClient)
.addConverterFactory(rest.JacksonConverterFactory.create())
.build();
gitApiInterface = client.create(GitApiInterface.class);
}
return gitApiInterface ;
}
和我的gradle依赖
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.1'
compile 'com.squareup.retrofit:retrofit:2.0.0-beta4'
compile 'com.squareup.okhttp:okhttp:2.4.0'
compile 'com.squareup.retrofit:converter-gson:2.0.0-beta1'
compile 'com.squareup.retrofit:converter-jackson:2.0.0-beta1'
compile 'com.squareup.okhttp3:okhttp:3.0.0'
}
答案 0 :(得分：0)
在json你有
TOTAL_COUNT
在java中你有
TOTALCOUNT
您应该使用相同的名称或使用@JsonProperty注释，如下所示：
@JsonProperty("total_count)
private int totalcount;
