使用 java 在 eclipse 中创建的 Jersey Tomcat Web 服务器的 404 错误
404 Error for a Jersey Tomcat web server created in eclipse with java
我从一个动态网络项目开始创建了一个服务器。当我通过输入
向它发出请求时
http://localhost:8080/restserver/myserver
或
http://localhost:8080/restserver/myserver/myserver
进入我的网络浏览器的搜索栏，我收到了回复
HTTP Status 404 – Not Found
Type Status Report
Message /restserver/src/demo/demo
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Apache Tomcat/9.0.13
我不知道我的服务器程序需要更改什么。我一直在关注 this tutorial 来设置我的服务器，看起来他们没有比我多多少。
我对我的请求的期望响应是
我几乎什么都试过了。删除并重新安装 eclipse 和 tomcat，删除我的 ~/.m2/repository 文件夹。日志文件看起来基本上 like this,

（我知道 302 凸轮来自哪里，刚看到这个）
所以我认为可能是因为第三列中的 - 请求未通过身份验证？我也不明白 catalina.properties file，但我按照这些说明进行操作，但没有帮助。我还阅读了一些关于代理的内容，但我并没有真正理解，因为我不知道如何禁用代理。

您需要在映射中使用 Jersey 控制器 com.sun.jersey.spi.container.servlet.ServletContainer 并指定资源路径
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.resources</param-value> <!--comma separated packages-->
</init-param>
并为 class javax.xml.bind.JAXBContext
添加依赖
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.2.6</version>
</dependency>
关于 Web 模块版本 4，我可以 运行 该应用程序。我正在使用 java 8 和 tomcat 9.
如果您需要帮助，请post发表评论
尽管构建成功了，但我最初得到的是 HTTP 状态 404 – 未找到。我遵循了之前的所有建议，但在控制台中遇到了类似的错误。按照标记错误和警告进行搜索后。
第一步：
我去项目右键->属性->部署程序集，我添加了Maven Depencencies Libray，之后又出现了一个严重的警告。
第二步：似乎需要 pom 中的依赖项才能完美地工作
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.1.2</version>
</dependency>
就在jaxb-api
之前
对我来说，所有这些框架协同工作的主要问题是 eclipse 中的设置。您需要能够安装并连接兼容的资源。例如，我还设法 运行 正确地使用了上面提到的 Dynamic Web Project 4.0
第三步：
我注意到你提到这个
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
在那种情况下，提及 source 和 target 版本意味着您的整个项目将在 Java 1.6 兼容性中编译。也许这就是您不能 运行 将其作为 Dynamic Web Project 4.0 的原因，因为它需要 Java 1.8 和更新版本。
在我的场景中，我正确设置了所有首选项，然后执行该 pom 并将选项中的所有内容恢复为 Java 1.6，所以我将其删除并正确执行

您需要在映射中使用 Jersey 控制器 com.sun.jersey.spi.container.servlet.ServletContainer 并指定资源路径
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.resources</param-value> <!--comma separated packages-->
</init-param>
并为 class javax.xml.bind.JAXBContext
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.2.6</version>
</dependency>
关于 Web 模块版本 4，我可以 运行 该应用程序。我正在使用 java 8 和 tomcat 9.
如果您需要帮助，请post发表评论
尽管构建成功了，但我最初得到的是 HTTP 状态 404 – 未找到。我遵循了之前的所有建议，但在控制台中遇到了类似的错误。按照标记错误和警告进行搜索后。
第一步：
我去项目右键->属性->部署程序集，我添加了Maven Depencencies Libray，之后又出现了一个严重的警告。
第二步：似乎需要 pom 中的依赖项才能完美地工作
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.1.2</version>
</dependency>
就在jaxb-api
之前对我来说，所有这些框架协同工作的主要问题是 eclipse 中的设置。您需要能够安装并连接兼容的资源。例如，我还设法 运行 正确地使用了上面提到的 Dynamic Web Project 4.0
第三步：
我注意到你提到这个
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
在那种情况下，提及 source 和 target 版本意味着您的整个项目将在 Java 1.6 兼容性中编译。也许这就是您不能 运行 将其作为 Dynamic Web Project 4.0 的原因，因为它需要 Java 1.8 和更新版本。
在我的场景中，我正确设置了所有首选项，然后执行该 pom 并将选项中的所有内容恢复为 Java 1.6，所以我将其删除并正确执行
