## RxJersey Proxy Client
|
|
|
|
Proxy client provides convenient way to call resources without constructing request. Also it allows to reuse resource interfaces between microservices.
|
|
|
|
In order to enable RxJava in proxy client register Jersey feature
|
|
```java
|
|
RxJerseyClientFeature rxJerseyClientFeature = new RxJerseyClientFeature()
|
|
.register(client); //should be non-blocking client implementation
|
|
resourceConfig.register(rxJerseyClientFeature);
|
|
```
|
|
Default client with Grizzly connector will be used if not provided
|
|
|
|
|
|
## Remote resource injection
|
|
You can inject proxy client with `@Remote` annotation, in addition you can inject `WebTarget` or `RxWebTarget`
|
|
```java
|
|
@Path("/example/")
|
|
public class GithubResource {
|
|
|
|
@Remote("https://api.github.com/")
|
|
private GithubApi githubApi;
|
|
|
|
@Remote("https://api.github.com/")
|
|
private WebTarget webTarget;
|
|
|
|
@GET
|
|
@Path("github")
|
|
public Single<GithubRepository> getRepository() {
|
|
return githubApi.getRepository("alex-shpak", "rx-jersey").toSingle();
|
|
}
|
|
}
|
|
```
|
|
|
|
## Manual proxy client creation
|
|
You can use `WebResourceFactory` from `net.winterly.rxjersey.client` package in order to create proxy client
|
|
|
|
#### RxJava
|
|
```java
|
|
WebResourceFactory.newResource(
|
|
ResourceInterface.class,
|
|
rxWebTarget,
|
|
new ObservableClientMethodInvoker()
|
|
);
|
|
```
|
|
#### RxJava 2
|
|
```java
|
|
WebResourceFactory.newResource(
|
|
ResourceInterface.class,
|
|
webTarget,
|
|
new FlowableClientMethodInvoker()
|
|
);
|
|
```
|
|
|
|
## Url resolving
|
|
Below is example of URL merging based on `@Remote` annotation value
|
|
|
|
| Annotation Value | Jersey Context Path | Result URL |
|
|
| ----------------------------- | --------------------------- | ---------------------------- |
|
|
| @Remote("http://example.com") | http://baseurl.com/resource | http://example.com/ |
|
|
| @Remote("/resource/") | http://baseurl.com/some | http://baseurl.com/resource/ | |
