Dropwizard REST：由于某种原因，获取请求被重定向302

Question

I built a REST server using Dropwizard following their tutorial here . The server should serve a single service - display Hello world message.

This is the output when I launched it:

c:\\Users\\administrator\\Eclipse workspaces\\Web\\DropwizardExample>java -jar target\\DropwizardExample-0.0.1-SNAPSHOT.jar server src\\main\\resources\\hello-world.yml INFO [2016-06-15 12:21:45,341]

org.eclipse.jetty.util.log: Logging initialized @1464ms INFO [2016-06-15 12:21:45,449] io.dropwizard.server.ServerFactory: Starting hello-world INFO [2016-06-15 12:21:45,459] io.dropwizard.server.SimpleServerFactory: Registering jersey handler with root path prefix: /hello-world INFO [2016-06-15 12:21:45,477] io.dropwizard.server.SimpleServerFactory: Registering admin handler with root path prefix: /admin INFO [2016-06-15 12:21:45,522] org.eclipse.jetty.setuid.SetUIDListener: Opened hello-world@17d2e85{HTTP/1.1}{0.0.0.0:8080} INFO [2016-06-15 12:21:45,525] org.eclipse.jetty.server.Server: jetty-9.2.z-SNAPSHOT INFO [2016-06-15 12:21:46,207] io.dropwizard.jersey.DropwizardResourceConfig: The following paths were found for the configured resources:

The yml file is as follows:

template: Hello, %s!
defaultName: Stranger

server:
  type: simple
  applicationContextPath: /hello-world
  adminContextPath: /admin
  connector:
    type: http
    port: 8080

When I try to go to

http://localhost:8080/hello-world

On IE or Chrome, it adds another slash at the end of the address and yields:

127.0.0.1 - - [15/Jun/2016:12:26:48 +0000] "GET /hello-world HTTP/1.1" 302 - "-" "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4. 0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C; .NET4.0E)" 3

127.0.0.1 - - [15/Jun/2016:12:26:48 +0000] "GET /hello-world/ HTTP/1.1" 404 43 "-" "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/ 4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C; .NET4.0E)" 3

at the console.

If I manually add the slash at the end, it directly gives me 404.

Can you assist please?

Answer 1

Well, I understood the problem. I added the following to the yml file:

server:
  type: simple
  applicationContextPath: /hello-world
  adminContextPath: /admin
  connector:
    type: http
    port: 7777

Well, I am not sure I understood completley why, but it appears to be that a simple server is not required here, but the default one. So after removing this segment, I recieved 200 OK.
