今天在接入阿里巴巴平台和qqSDK时出了个意想不到的错，下面分享一下

 以上报错，仔细一看，是oauth2的授权码失效了，这个没啥重新授权，运行代码授权

警告: Synchronous API [ namespace=system.oauth2,name=getToken] send request timeout.

 从上面的分析来看是说那个类

SerializationConfig

里面没有

with（）
参数：是一个Feature的数组
[Lorg/codehaus/jackson/map/SerializationConfig$Feature;]

从整个项目来看，项目中并没有这样的包目录（org.codehaus.jackson.map）存在，可以确定是第三方包出现了问题，于是开始在项目搜索这个类

SerializationConfig

操作步骤如下：

1.选中你的项目

2.ctr+h 打开搜索对话框

在containing text 下面的对话框中输入检索内容。

在filename pattern 下面的对话框中输入匹配的文件格式。

然后在选中scope (检索范围)下面选中 selected resources

开始检索，结果如下

 从上面的结果可以看出确实存在好几个这个名称的类，但是还得看包结构，复合出错提示的只有两个；

一个是jackson-mapper-asl-19.13.jar,另一个是Sdk4J.jar(其它的包为什么不是：sdk4j.jar,这个jar包是我重新对Sdk4J.jar打的包删除里面的自带的jackson-mapper-asl-19.13.jar包）就是这个自带的jar出现了问题)

由于版本过低的问题，里面的类SerializationConfig缺少了新的方法（此处是with(Fearture...fearture)），而且项目运行时会先去用这个jar里面的class,(原因就是先找到先用谁，结果是类找到了，方法却找不到，却又不继续往下找，所以即使是你加入了最新的jackson-mapper-asl的jar包，也没有用)，上几个解图，看看结构

这个是Sdk4J.jar里面的

可以看到确实没有with(Fearture...f)方法

在上个jackson-mapper-asl.jar

这个里面，却引用不到，真是坑啊

所以解决方法有三个

1.让项目先找到最新的jar（比较困难，不易实现，不做进一步的深究了，毕竟项目赶时间）

2.将又问题的改个名字在引用，这个最方便，但是没有解决掉根本问题

3.解压有问题的jar把里面的低版本的jar删除，或替换为最新的，然后在打包回去

jar cvf sdk4j.jar（打包后的名称） file(解压后删除低版本引用的文件目录)

最后一步检查是否可行运行代码测试结果如下：

取到数据，成功。问题解决了。
