ProcessingException：org.codehaus.jackson.map.JsonMappingException：無法反序列X的實例進行START_ARRAY令牌

Question

private <T> T[] getObjects(Class<T> tClass, String version) { 
    String subUrl = "/versions/" + version; 
    return ClientBuilder.newClient() 
         .target(url) 
         .request() 
         .get(new GenericType<T[]>(tClass) {}); 
} 

這裏JSON對象

[ 
    { 
     "id":1, 
     "name":"test", 
     "country":"USA" 
    }, 
    { 
     "id":2, 
     "name":"test_1", 
     "country":"cameroon" 
    } 
] 

的getObjects方法的調用：

X[] x = getObjects(X.class, currentVersionName); 

我得到這個例外：

我使用這些依賴關係：

<dependency> 
    <groupId>org.jboss.resteasy</groupId> 
    <artifactId>resteasy-client</artifactId> 
    <version>3.1.2.Final</version>

嘗試改變：

private <T> T[] getObjects(Class<T> tClass, String version) 

到

private <T> T[] getObjects(Class<T[]> tClass, String version) 

和呼叫方將是

X[] x = getObjects(X[].class, currentVersionName);
