升级 Jersey 版本后随机 REST API 调用失败
Random REST API calls fail after upgrading Jersey version
最近不得不将 Jersey 的版本从 2.5.1（原因稍后解释）升级到 2.7，自从升级后，每次我将代码上传到服务器时，随机 API 调用开始失败并出现以下问题堆栈跟踪：

每次我进行干净的构建并重新上传时，一组新的方法开始失败（并且之前失败的方法开始工作）而无需任何代码更改！
在尝试 2.7 之后，我切换到 2.25.1，这又打开了另一个蠕虫罐头，所以我尝试使用 2.5.2（而不是原来的 2.5.1），它和 2.5 有同样的问题.1.我切换到 2.8，它有与 2.7 相同的随机问题。
目前的状态是，无论是版本 2.7 还是 2.8，REST API 方法的一个小的（至少看起来）随机子集失败并显示与上述类似的消息。
我想找出原因并修复它。
切换球衣版本时遵循的方法
我会清理 /WEB-INF/lib 文件夹，将 pom.xml 中的 jersey.version 变量更改为新版本。然后 Eclipse 将获取所有必要的库并重新构建代码。 运行 mvn appengine:update 将重新填充 /WEB-INF/lib 文件夹并将所有内容打包。
我做了几次干净（完整）的构建，以确保不会混合来自不同版本的人工制品。
从 2.5.1 升级的原因
必须添加一个方法（具有以下签名）：
public Response importChildren(@Context ContainerRequestContext reqCtx,
@PathParam(ID) String id, @FormDataParam("file") InputStream csvStream,
@FormDataParam("test") String testStr)
这将需要一个 CSV 文件的 InputStream 并对其进行处理。因此必须添加 jersey-media-multipart。与版本 2.5.x 一起使用（未尝试使用 2.6），这开始出错，因为它试图将 InputStream 写入临时文件（在 [=55= 中禁止写入磁盘） ] App Engine (Standard)，这是我正在使用的。
对于 >= 2.7 的版本，可以通过添加内容为 jersey.config.multipart.bufferThreshold = -1
的文件 jersey-multipart-config.properties 来避免这种写入临时文件的趋势
绝望的解决方法
如果没有别的办法，我可以将 CSV 处理代码从 Jersey 介导的方法中移出并移到一个简单的 servlet 中。然后我不需要 jersey-media-multipart 并且可以回到使用版本 2.5.1，所有代码都可以可靠地工作。
这个
java.lang.NullPointerException

是 Jersey 和特定底层 HK2 内核版本之间的互操作 known bug，它附带 Jersey 2.7 作为传递依赖
We've switched to HK2 2.3.0-b05 in 2.9-SNAPSHOT. After we release 2.9 the problem should be gone.
看起来最近修复了该错误的 Jersey 版本是 2.9。但如果您更愿意继续使用 2.7，请找到以下解决方法。
通过 Maven 强制使用 hk2-api 2.3.0-b05 版本：
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-common</artifactId>
<version>2.7</version>
<exclusions>
<exclusion>
<groupId>org.glassfish.hk2</groupId>
<artifactId>hk2-api</artifactId>
<!-- this is to exclude 2.2.0 version -->
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.glassfish.hk2</groupId>
<artifactId>hk2-api</artifactId>
<version>2.3.0-b05</version>
</dependency>
您 pom.xml 中的一些其他 Jersey 工件可能需要排除练习，只需相应地检查 mvn dependency:tree ...
完整的解决方案
by @Kostiantyn 让我走上了正确的道路，尽管我必须做一些小的改变才能让它工作。为了让其他人可以避免我不得不面对的时间浪费，我将在下面给出完整的解决方案。
正如@Kostiantyn 指出的那样，我需要升级到 Jersey 2.9 以消除 Jersey 和 HK2 之间的互操作错误。但是，当我切换到 2.9 时，我开始在所有 POST/PUT 方法（所有这些 @Consumes(MediaType.APPLICATION_JSON):
上收到以下错误
org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$TerminalReaderInterceptor aroundReadFrom:
MessageBodyReader not found for media type=application/json, type=class com.example.json.StarDto,
genericType=class com.example.json.StarDto
这是个大问题，为了解决这个问题，我添加了以下依赖项（根据@Kostiantyn 的建议）：
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>${jersey.version}</version>
<scope>runtime</scope>
</dependency>
使用这个新添加的依赖项进行测试后，旧的错误消失了，相反我开始在我的 POST 方法（没有测试 PUT 方法）中得到以下信息：
org.glassfish.jersey.server.ContainerException: java.lang.NoSuchMethodError:
com.fasterxml.jackson.jaxrs.cfg.EndpointConfigBase.<init>(Lcom/fasterxml/jackson/databind/cfg/MapperConfig;
在尝试了很多不同的事情之后，我终于意识到 jersey-media-json-jackson 正在引入 jackson-jaxrs-base-2.3.2.jar，这与 jackson-jaxrs-base-2.7.1.jar（这是我需要的版本）。所以添加 jersey-media-json-jackson 并排除以下内容终于解决了我所有的问题：
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>${jersey.version}</version>
<scope>runtime</scope>
<exclusions>
<exclusion>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-base</artifactId>
</exclusion>
</exclusions>
</dependency>
尝试将我的应用程序部署到 weblogic 服务器时遇到完全相同的问题。
重新启动 weblogic 托管服务器对我有用。
停止：
通过在 Web 浏览器的 URL 行中键入 http://[host name]:[port]/console 来启动 WebLogic Server 管理控制台。
在“域结构”下，单击“环境”>“服务器”。
在右窗格中，单击“控制”选项卡。
Select 您要停止的托管服务器。
单击要停止的托管服务器下方的关闭按钮。
Select 当工作完成时正常关闭服务器或 select 立即强制关闭立即停止服务器而不完成正在进行的任务。
在“服务器生命周期助手”窗格中，单击“是”完成关闭。
开始：
确保 WebLogic Server 和节点管理器 运行。
通过在 Web 浏览器的 URL 行中键入 http://[host name]:[port]/console 来启动 WebLogic Server 管理控制台。
在“域结构”下，单击“环境”>“服务器”。
在右窗格中，单击“控制”选项卡。
Select 您要启动的托管服务器。
单击要启动的托管服务器下方的“启动”按钮。
最近不得不将 Jersey 的版本从 2.5.1（原因稍后解释）升级到 2.7，自从升级后，每次我将代码上传到服务器时，随机 API 调用开始失败并出现以下问题堆栈跟踪：

每次我进行干净的构建并重新上传时，一组新的方法开始失败（并且之前失败的方法开始工作）而无需任何代码更改！
在尝试 2.7 之后，我切换到 2.25.1，这又打开了另一个蠕虫罐头，所以我尝试使用 2.5.2（而不是原来的 2.5.1），它和 2.5 有同样的问题.1.我切换到 2.8，它有与 2.7 相同的随机问题。
目前的状态是，无论是版本 2.7 还是 2.8，REST API 方法的一个小的（至少看起来）随机子集失败并显示与上述类似的消息。
我想找出原因并修复它。
切换球衣版本时遵循的方法
我会清理 /WEB-INF/lib 文件夹，将 pom.xml 中的 jersey.version 变量更改为新版本。然后 Eclipse 将获取所有必要的库并重新构建代码。 运行 mvn appengine:update 将重新填充 /WEB-INF/lib 文件夹并将所有内容打包。
我做了几次干净（完整）的构建，以确保不会混合来自不同版本的人工制品。
从 2.5.1 升级的原因
必须添加一个方法（具有以下签名）：
public Response importChildren(@Context ContainerRequestContext reqCtx,
@PathParam(ID) String id, @FormDataParam("file") InputStream csvStream,
@FormDataParam("test") String testStr)
这将需要一个 CSV 文件的 InputStream 并对其进行处理。因此必须添加 jersey-media-multipart。与版本 2.5.x 一起使用（未尝试使用 2.6），这开始出错，因为它试图将 InputStream 写入临时文件（在 [=55= 中禁止写入磁盘） ] App Engine (Standard)，这是我正在使用的。
对于 >= 2.7 的版本，可以通过添加内容为 jersey.config.multipart.bufferThreshold = -1
jersey-multipart-config.properties 来避免这种写入临时文件的趋势
绝望的解决方法
如果没有别的办法，我可以将 CSV 处理代码从 Jersey 介导的方法中移出并移到一个简单的 servlet 中。然后我不需要 jersey-media-multipart 并且可以回到使用版本 2.5.1，所有代码都可以可靠地工作。
这个
java.lang.NullPointerException

是 Jersey 和特定底层 HK2 内核版本之间的互操作 known bug，它附带 Jersey 2.7 作为传递依赖
We've switched to HK2 2.3.0-b05 in 2.9-SNAPSHOT. After we release 2.9 the problem should be gone.
看起来最近修复了该错误的 Jersey 版本是 2.9。但如果您更愿意继续使用 2.7，请找到以下解决方法。
通过 Maven 强制使用 hk2-api 2.3.0-b05 版本：
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-common</artifactId>
<version>2.7</version>
<exclusions>
<exclusion>
<groupId>org.glassfish.hk2</groupId>
<artifactId>hk2-api</artifactId>
<!-- this is to exclude 2.2.0 version -->
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.glassfish.hk2</groupId>
<artifactId>hk2-api</artifactId>
<version>2.3.0-b05</version>
</dependency>
您 pom.xml 中的一些其他 Jersey 工件可能需要排除练习，只需相应地检查 mvn dependency:tree ...
完整的解决方案
正如@Kostiantyn 指出的那样，我需要升级到 Jersey 2.9 以消除 Jersey 和 HK2 之间的互操作错误。但是，当我切换到 2.9 时，我开始在所有 POST/PUT 方法（所有这些 @Consumes(MediaType.APPLICATION_JSON):
org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$TerminalReaderInterceptor aroundReadFrom:
MessageBodyReader not found for media type=application/json, type=class com.example.json.StarDto,
genericType=class com.example.json.StarDto
这是个大问题，为了解决这个问题，我添加了以下依赖项（根据@Kostiantyn 的建议）：
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>${jersey.version}</version>
<scope>runtime</scope>
</dependency>
使用这个新添加的依赖项进行测试后，旧的错误消失了，相反我开始在我的 POST 方法（没有测试 PUT 方法）中得到以下信息：
org.glassfish.jersey.server.ContainerException: java.lang.NoSuchMethodError:
com.fasterxml.jackson.jaxrs.cfg.EndpointConfigBase.<init>(Lcom/fasterxml/jackson/databind/cfg/MapperConfig;
在尝试了很多不同的事情之后，我终于意识到 jersey-media-json-jackson 正在引入 jackson-jaxrs-base-2.3.2.jar，这与 jackson-jaxrs-base-2.7.1.jar（这是我需要的版本）。所以添加 jersey-media-json-jackson 并排除以下内容终于解决了我所有的问题：
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>${jersey.version}</version>
<scope>runtime</scope>
<exclusions>
<exclusion>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-base</artifactId>
</exclusion>
</exclusions>
</dependency>
尝试将我的应用程序部署到 weblogic 服务器时遇到完全相同的问题。
重新启动 weblogic 托管服务器对我有用。
停止：
通过在 Web 浏览器的 URL 行中键入 http://[host name]:[port]/console 来启动 WebLogic Server 管理控制台。
在“域结构”下，单击“环境”>“服务器”。
在右窗格中，单击“控制”选项卡。
Select 您要停止的托管服务器。
单击要停止的托管服务器下方的关闭按钮。
Select 当工作完成时正常关闭服务器或 select 立即强制关闭立即停止服务器而不完成正在进行的任务。
在“服务器生命周期助手”窗格中，单击“是”完成关闭。
开始：
确保 WebLogic Server 和节点管理器 运行。
通过在 Web 浏览器的 URL 行中键入 http://[host name]:[port]/console 来启动 WebLogic Server 管理控制台。
在“域结构”下，单击“环境”>“服务器”。
在右窗格中，单击“控制”选项卡。
Select 您要启动的托管服务器。
单击要启动的托管服务器下方的“启动”按钮。
