Question

如果发生错误（https://jersey.java.net/documentation/latest/representations.html#d0e3586）

，我正在尝试关注Jersey文档以启用非200响应

我的代码如下：

@POST
@Produces(MediaType.TEXT_PLAIN)
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public ResponseBuilder getData(@FormParam("one") String one,@FormParam("two") String two,@FormParam("three") String three) {
    if(one.isEmpty() || two.isEmpty() || three.isEmpty()) {
        logger.error("Missing params for getData");
        throw new WebApplicationException(501);
    }
    return Response.ok();
}
}

遗憾的是，这会产生以下错误：

[2015-02-01T16：13：02.157 + 0000] [glassfish 4.1] [SEVERE] [] [org.glassfish.jersey.message.internal.WriterInterceptorExecutor] [tid：_ThreadID = 27 _ThreadName = http-listener- 1（2）] [timeMillis：1422807182157] [levelValue：1000] [[ 找不到媒体类型= text / plain的MessageBodyWriter，类型= class org.glassfish.jersey.message.internal.OutboundJaxrsResponse $ Builder，genericType = class javax.ws.rs.core.Response $ ResponseBuilder。]]

问题是您的方法的返回类型。它必须是Response而不是ResponseBuilder。

将您的代码更改为以下内容，它应该有效：

@POST
@Produces(MediaType.TEXT_PLAIN)
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public Response getData(@FormParam("one") String one,@FormParam("two") String two,@FormParam("three") String three) {
    if(one.isEmpty() || two.isEmpty() || three.isEmpty()) {
        logger.error("Missing params for getData");
        throw new WebApplicationException(501);
    }
    return Response.ok();
}

找不到媒体类型= text / plain的Jersey MessageBodyWriter
