这到底是怎么回事？

The ResourceConfig instance does not contain any root resource classes.

SEVERE: Exception occurred when intialization

滤波器：

<filter>
    <filter-name>JerseyFilter</filter-name>
    <filter-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</filter-class>

    <init-param>
        <param-name>com.sun.jersey.config.feature.Redirect</param-name>
        <param-value>true</param-value>
    </init-param>

    <init-param>
        <param-name>com.sun.jersey.config.property.JSPTemplatesBasePath</param-name>
        <param-value>/views/</param-value>
    </init-param>

    <init-param>
        <param-name>com.sun.jersey.config.property.WebPageContentRegex</param-name>
        <param-value>/(images|css|jsp)/.*</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>JerseyFilter</filter-name>
    <url-pattern>/myresource/*</url-pattern>
</filter-mapping>

法典：

@Path ("/admin")
public class AdminUiResource {

  @GET
  @Produces ("text/html")
  @Path ("/singup")
  public Viewable getSignUp () {
    return new Viewable("/public/signup", "Test");
  }
}

答案 1

您是否尝试过添加

<init-param>
  <param-name>com.sun.jersey.config.property.packages</param-name>
  <param-value>my.package.name</param-value>
</init-param>

到你的SpringServlet定义？显然，将 my.package.name 替换为 AdminUiResource 所在的包，并确保它位于类路径中。

我是泽西岛的新手 - 我有同样的问题，但是当我删除“/”并只使用@path（“admin”）时，它起作用了。

@Path("admin")
public class AdminUiResource { ... }
