This library is created to simplify the process of creating REST client in Spring Framework. Instead writing a large amount of identical code you should just create java interface and add a few annotations.

Add maven repository :

<repositories>
     <repository>
         <id>oss-sonatype-staging</id>
         <name>sonatype</name>
         <url>https://oss.sonatype.org/content/groups/staging</url>
     </repository>
</repositories>

and dependency to pom.xml:

<dependency>
    <groupId>com.art4ul</groupId>
    <artifactId>jcoon</artifactId>
    <version>0.3.2-SNAPSHOT</version>
</dependency>

To create Rest client you need to perform only 3 steps:

1. Add the following bean definition in spring application context:

   <bean class="com.art4ul.jcoon.bean.RestClientAnnotationBeanPostProcessor"/>

or if you want use custom RestTemplate with message converter:

```xml
<bean id="jsonMarshaller" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"/>

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate" depends-on="jsonMarshaller">
     <property name="messageConverters" ref="jsonMarshaller"/>
</bean>

<bean class="com.art4ul.jcoon.bean.RestClientAnnotationBeanPostProcessor" depends-on="restTemplate">
     <constructor-arg index="0" ref="restTemplate"/>
</bean>
```

2. Create interface and discribe methods using Spring Web annotations like: @RequestMapping, @RequestParam, @RequestBody etc.

   @RequestMapping("example1")
   public interface ExampleRestClient {
       @BaseUrl
       void setBaseUrl(String url);
   
       @RequestMapping(value = "/exampleGet", method = RequestMethod.GET)
       ResultModel exampleGetRequest(@RequestParam("name") String name);
   
   }

3. And use it in your code:

   @Service
   public class TestService {
   
       @RestClient
       private ExampleRestClient restClient;
   
       public void doTest() {
   
           restClient.setBaseUrl("http://localhost:8080");
   
           ResultModel result = restClient.exampleGetRequest("world");
       }
   }
