迁移到 Jersey 2.x 在调用我的 api 时出现 404 错误

Question

我正在从 com.sun.jersey 1.x 迁移到 org.glassfish.jersey 2.x，

我的 web.xml 看起来像：

     <?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<listener>

<servlet>
    <servlet-name>jersey-servlet</servlet-name>

    <init-param>

    </init-param>

    </init-param>

    <init-param>

        <param-value>${jersey.enable.trace}</param-value>
    </init-param>
    <init-param>
        <param-name>jersey.disable.wadl</param-name>
        <param-value>${jersey.disable.wadl}</param-value>
    </init-param>

    <url-pattern>/*</url-pattern>
</filter-mapping>

<welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

因此，在 com.xyz.webservices.resources 下定义的资源，无论何时被称为 '/app/api/data' 都会说 404 页面未找到。 我在这里做错了吗？

我通过修改我的 web.xml 使代码工作：

    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.jersey.series.spring.security.service,com.xyz.webservices</param-value>
    </init-param>

    <!-- Enable / Disable Jersey Tracing -->
    <init-param>
        <param-name>jersey.config.server.tracing</param-name>
        <param-value>${jersey.enable.trace}</param-value>
    </init-param>
    <init-param>
        <param-name>jersey.disable.wadl</param-name>
        <param-value>${jersey.disable.wadl}</param-value>
    </init-param>

    <!-- Enabling Jackson Feature and Logging -->
    <init-param>
        <param-name>jersey.config.server.provider.classnames</param-name>
        <param-value>org.glassfish.jersey.jackson.JacksonFeature,org.glassfish.jersey.filter.LoggingFilter,org.glassfish.jersey.server.filter.EncodingFilter,org.glassfish.jersey.message.DeflateEncoder,org.glassfish.jersey.message.GZipEncoder</param-value>
    </init-param>
