问题是，每当我尝试生成 JSON 以外的任何媒体类型的响应时，我都会收到“MessageBodyWriter”未找到错误。 但是响应对于 Application_JSON 输出工作正常。 我在我的 Maven POM 中使用了几个依赖项，所以 MessageBodyWriter 可能被覆盖或者可能只针对它包含的 JSON。
这里是 pom 依赖项 -

我使用的示例 Java 类是 -
package com.va;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.glassfish.jersey.server.mvc.Viewable;
@Path("orders")
public class OrderView{
@GET
@Produces(MediaType.TEXT_HTML)
public Viewable index() {
return new Viewable("index");
}
}
另外，我将 index.htm 文件保存在 webapp 文件夹中。 web.xml 的配置如下 -
<servlet>
<servlet-name>Jersey REST Service</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.va</param-value>
</init-param>
<init-param>

</init-param>

<param-value>/(webapp)/.*</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
关于访问 URL localhost:8080/myapp/orders 我收到 HTTP 500 错误和控制台错误
org.glassfish.jersey.message.internal.WriterInterceptorExecutor$TerminalWriterInterceptor aroundWriteTo
SEVERE: MessageBodyWriter not found for media type=text/html, type=class org.glassfish.jersey.server.mvc.Viewable, genericType=class org.glassfish.jersey.server.mvc.Viewable.
请指导我是什么问题。提前致谢。:)
最佳答案
这里有几点需要注意，在使用 jersey mvc 模板时，您应该使用 servlet 过滤器而不是 serlvet。此外，您的一些 init 参数引用 Jersey 1，应更改为等效的 Jersey 2。更多信息 Jersey MVC Template
更新了 web.xml。试一试。

<filter-name>Jersey REST Service</filter-name>
<filter-class>org.glassfish.jersey.servlet.ServletContainer</filter-class>
