Question

我正在尝试使用JAX-RS'（Jersey）MVC模式。尝试到达http://localhost:8080/myproject/foos/test会导致错误：

java.io.IOException: The template name, /view, could not be resolved to a fully qualified template name

http://localhost:8080/myproject/foos会导致同样的错误。

我错过了什么？

资源：

package resources;

import com.sun.jersey.api.view.Viewable;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("foos")
public class FooResource {

    @GET
    @Produces(MediaType.TEXT_HTML)
    public Viewable get() {

        return new Viewable("/index", this);

    }   

    @GET
    @Path("{id}")
    @Produces(MediaType.TEXT_HTML)
    public Viewable get(@PathParam("id") String id) {

        return new Viewable("/view", id);

    } 

}

查看：

WEB-INF / jsp / resources / FooResource

的index.jsp
view.jsp的

的web.xml：

进行了以下更改：

的web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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_3_0.xsd">
    <session-config>
        <session-timeout>30</session-timeout>
    </session-config>

    <welcome-file-list>
        <welcome-file>welcome.jsp</welcome-file>
    </welcome-file-list>

        </init-param>
        <init-param>

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

</web-app>

资源：

@Path("foos")
public class FooResource {

    @GET
    @Produces(MediaType.TEXT_HTML)
    public Viewable index() {

        return new Viewable("/foos/index", this);

    }   

    @GET
    @Path("{id}")
    @Produces(MediaType.TEXT_HTML)
    public Viewable view(@PathParam("id") String id) {

        return new Viewable("/foos/view", id);

    } 

}

查看：

\的welcome.jsp
\ WEB-INF \视图\ FOOS \
- 的index.jsp
- view.jsp的

我在Jetty 9下运行了同样的错误。应用程序使用 mvn clean jetty运行但在打包为战争并在Jetty下部署时出现此错误。这是web.xml中的修复程序，对我有用：

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

是的，就是这样。所以，希望这可以帮助那些偶然发现这一点的人。我的配置与craig的配置基本相同，但有额外的斜线。

从初始检查开始，我认为您希望将index.jsp和view.jsp直接放在WEB-INF / jsp中。

无法将JAX-RS服务连接到MVC模板
