Files had various formatting differences, as did pull requests. Rather than
create our own style, this inherits and requires the well documented Google
Java Style.
Feign has `MethodMetadata.bodyType()`, but never passed it to encoders.
Encoders that register type adapters need to do so based on the
interface desired as opposed to the implementation class. This change
breaks api compatibility for < 8.x, by requiring an additional arg
on `Encoder.encode`.
see https://github.com/square/retrofit/issues/713
Dagger 1.x and 2.x are incompatible. Rather than choose one over the
other, this change removes Dagger completely. Users can now choose any
injector, constructing Feign via its Builder.
This change also drops support for javax.inject.Named, which has
been replaced by feign.Param.
see #120
Parameters annotated with `Param` expand based on their `toString`. By
specifying a custom `Param.Expander`, users can control this behavior,
for example formatting dates.
```java
@RequestLine("GET /?since={date}") Result list(@Param(value = "date", expander = DateToMillis.class) Date date);
```
Closes#122
Feign 8.x will no longer support Dagger, nor interfaces annotated with `javax.inject.@Named`. Users must migrate from `javax.inject.@Named` to `feign.@Param` via Feign v7.1+ before attempting to update to Feign 8.0.
For example, the following uses `@Param` as opposed to `@Named` to annotate template parameters.
```java
interface GitHub {
@RequestLine("GET /repos/{owner}/{repo}/contributors")
List<Contributor> contributors(@Param("owner") String owner, @Param("repo") String repo);
}
```
AssertJ has more powerful test assertions and does not run the risk of
interfering with the classpath of main code, such as guava does. This
removes guava from test and example code and adjusts using AssertJ in
some cases.
JUnit Rules, such as MockWebServerRule, reduce boilerplate setup present
in our tests. By migrating off TestNG, and onto rules, our tests become
more maintainable as JUnit is well understood.
Hi.
In JAX-RS section, adding 'JAXRSContract' is omitted.
So, I didn't understand the JAX-RS example correctly. And I got an exception when I run it.
If adding 'JAXRSContract' is added, It is helpful to beginners like me.
Thank you.
