免责声明: 我搜索了整个 StackOverflow 网络，看到了很多具有不同解决方案的问题，但没有任何帮助，因为其中大多数都有拼写错误或错误.war 文件名等。请不要将问题标记为重复。
对于我正在进行的最新项目，我需要使用 Jersey REST 服务，但是我完全陷入了 404 错误。
这是 web.xml 文件:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>VideoConverter</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>VideoConverter REST Service</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>videoconverter.rest</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>VideoConverter REST Service</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>
然后，这是我需要调用的 REST 方法的实现:
@Path("/convert")
public class ConvertControllerREST {
@GET
@Path("/getcommands")
@Produces("application/json")
public List<JSONObject> getCommands() {
// other logic here
}
我在以下 URL 上调用此 REST 方法:http://10.0.2.15:8080/VideoConverter/rest/convert/getcommands
Tomcat 7 日志完全没有显示错误，只有 404 - 请求 URL 时未找到。从此处下载最新的 Jersey 版本:https://jersey.java.net/download.html(RI 包)，并将我在上面的包中找到的所有 .jar 文件插入到 WEB-INF/lib 文件夹中。此外，我正在创建的 .war 文件与 web.xml 文件中所述的名称相同:VideoConverter.war。
任何想法可能是这里的问题？

最后更新: @Meiko 回答解决了一半的问题。由于出现了新的错误，我决定听取他的建议，将项目转换为 Maven archtype 以轻松解决这些问题。
最佳答案
编辑init-param对于 package scanning在你的 web.xml 中:
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>videoconverter.rest</param-value>
</init-param>
或者(异或!)将 Jersey 更新为 2.x 并更改 servlet-class :
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
com.sun.jersey是 jersey 1.x 的包名.
org.glassfish.jersey是jersey 2.x的基础包.
更新
问题:
SEVERE: MessageBodyWriter not found for media type=application/json, type=class java.util.ArrayList, genericType=java.util.List
您必须添加一个能够序列化/反序列化 JSON(处理指定媒体类型)的库。请参阅:https://jersey.java.net/documentation/latest/media.html#json
只需在此处下载 bundle :http://central.maven.org/maven2/org/glassfish/jersey/media/jersey-media-json-jackson/2.22.2/jersey-media-json-jackson-2.22.2.jar
将 jar 放在你的类路径中......
并编辑标签servlet-class至 <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class> ，就像已经展示的那样。
这应该足够了。
建议:我真的推荐你使用 maven。使用 Maven 原型(prototype)，您可以非常轻松地设置项目:
mvn archetype:generate \
-DarchetypeArtifactId=jersey-quickstart-webapp \
-DarchetypeGroupId=org.glassfish.jersey.archetypes \
-DinteractiveMode=false \
-DgroupId=com.example \
-DartifactId=simple-service-webapp \
-Dpackage=com.example \
-DarchetypeVersion=2.22.2
要启动这个应用程序:
mvn clean package tomcat7:run-war
