java.lang.NoSuchFieldError：INSTANCE

尝试通过StormSubmitter提交结构时，我得到

Caused by: java.lang.NoSuchFieldError: INSTANCE  at org.apache.http.impl.io.DefaultHttpRequestWriterFactory.<init>(DefaultHttpRequestWriterFactory.java:52)

我正在使用Spring。

我没有在Spout / Bolt构造函数中初始化HttpClient。相反，它是在prepare()通过螺栓方法从Spring Context中获取的类的构造函数中初始化的

代码的结构如下-

SomeBolt.java

@Componentpublic class SomeBolt extends BaseRichBolt {    private OutputCollector _collector;    private SomeClient someClient;    @Override    public void prepare(Map conf, TopologyContext context, OutputCollector collector) {        _collector = collector;        someClient = AppContext.getBean(SomeClient.class);    }}

SomeClient.java

@Componentpublic class SomeClient {    private final CloseableHttpClient httpClient;    public SomeClient() {        this.httpClient = (httpClient == null ? HttpClients.createDefault() : httpClient);    }}

AppContext.java

@Componentpublic class AppContext implements ApplicationContextAware {    private static ApplicationContext applicationContext;    @Override    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {        AppContext.applicationContext = applicationContext;    }    public static <T> T getBean(Class<T> c) {        return applicationContext.getBean(c);    }}

我遇到了类似的问题，在我的类路径中有两个包含相同类的jar，即httpcore-4.3和apache-httpcomponents-httpcore，我从类路径中删除了apache-httpcomponents-httpcore解决了该问题。

android java.lang.NoSuchFieldError: R$id.xxx

第一种情况 参考自http://www.shangxueba.com/jingyan/1856083.html

    将引用的自定义控件的xml文件中的最外层布局上面添加xmlns:sat=“http://schemas.Android.com/apk/res/控件所在位置的包名”可是在运行时就会报java.lang.NoSuchFieldError:包.R$id.xxx错。同时还会出现no resource identifier found for attribute 的错误。

    将xmlns:sat=“http://schemas.android.com/apk/res/控件所在位置的包名”更改为

    http://schemas.android.com/apk/res-auto 就不会报错了

第二种 参考：http://www.hankcs.com/program/mobiledev/e-androidruntime-fatal-exception-main-java-lang-nosuchfielderror.html

这个问题是由于主项目覆盖了库项目的xml所致，如果主项目中的某个xml里定义了一个跟库项目中的xml同名的xml，那么库中的xml将会被覆盖。这里的覆盖意思是，编译后只有主项目中的xml以及R.id，完全没有库项目的影子。所以才会有NoSuchFieldError的错误。

这个错误不会在编译的时候提示，算得上一个陷阱了。

解决方法很简单，删除主项目中的xml，整个项目只保留一份xml即可。

现象

这段时间在做主机迁移,搞定数据库和oss后,测试了下oss上传功能,结果服务器报错。 war包在本地运行是没有问题的，我把现在线上的war部署到迁移主机中，结果迁移主机还是如上报错。

com.sun.xml.ws.server.sei.TieHandler.createResponse INSTANCE
java.lang.NoSuchFieldError: INSTANCE
at org.apache.http.conn.ssl.SSLConnectionSocketFactory.<clinit>(SSLConnectionSocketFactory.java:144)

过程

找了阿里云的技术人员，他们说是因为害怕oracle商业纠纷，迁移后的新版本私有云edas不提供了oracle jdk组件，只提供open jdk组件，而之前的私有云提供oracle jdk组件的。

当时提了两个选择：

• 1.私有云开通oracle jdk服务，在数据库里改下配置，这样所有人都能使用。 但是公司云中心的人也害怕商业纠纷，不给开。
• 2.自己部署有oracle jdk 的ecs服务，但是ecs不能被edas托管，因为托管后，edas会强制使用open jdk，自己装的oracle jdk 不能用。 项目负责人选择还是使用edas部署，虽然这个项目两年都没改过代码。

解决

在这种情况下,只能使用openjdk,并需要自己解决这个问题。

失败的尝试

我下载了openjdk，并将代码全部改为了openjdk，然后本地打包测试，自信满满，结果还是报这个错误。

升级jar包

这样，可以肯定是war包有问题了，我升级了下oss的jar包，从2.8.x升级到3.10.2，还升级了其他相关的oss依赖。这次还是报错了。

解决问题

我又百度了下,感觉还是jar包冲突问题。我下载了jar的资源包，然后在idea中点击那个字段，发现右上角提示另一处还有相同的class，它的前缀是jar包名。 我看到了，找到了jar包，暴力删除了他，发现构建没问题，然后重新打包,本地测试,线上测试,都ok。

整个事件中

• 1.对edas新特性不熟悉是主要原因。
• 2.思维定势：因为之前也百度到是jar包冲突，可是在之前我war能在生产正常运行的前提下，思维会受到定势影响。而且刚开始使用oracle jdk，也没发现整个class的冲突。
