This is a library that provides you with a simple way to do http/https requests to your REST API.
<dependency>
<groupId>no.bouvet</groupId>
<artifactId>json-client</artifactId>
<version>1.0.5</version>
</dependency>
Create your json client like this:
JsonClient jsonClient = new JsonClient();
Or with a ObjectMapper like this:
JsonClient jsonClient = new JsonClient(objectMapper);
How to get your REST-API response for GET, POST, PUT and DELETE:
HttpResponse response = jsonClient.http().get("http://").response();
HttpResponse response = jsonClient.http().post("http://", new ObjectToPost()).response();
HttpResponse response = jsonClient.http().put("http://", new ObjectToPut()).response();
HttpResponse response = jsonClient.http().delete("http://").response();
How to get your response using https:
HttpResponse response = jsonClient.ssl().get("http://").response();
How to get and parse your response directly to your preferred object:
MyObject myObject = jsonClient.http().get("http://").object(MyObject.class);
How to get and parse your response directly to your preferred list:
List<MyObject> myObject = jsonClient.http().get("http://").list(MyObject.class);
How to get and parse your response directly to your preferred list of list:
List<MyObject> myObject = jsonClient.http().get("http://").listOfList(MyObject.class);
How you get and parse your response directly to your preferred map:
Map<String, MyObject> myObject = jsonClient.http().get("http://").map(MyObject.class);
How to poll for data and trigger when condition is fulfilled (example - TestObjectCondition )
MyObject myObject = jsonClient.http().poll("http://", MyObject.class, 5000, new TestObjectCondition(state));
How to poll for data without any conditions.
MyObject myObject = jsonClient.http().poll("http://", MyObject.class, 5000);
If you are using Spring and Joda DateTime you might need to configure it using JsonClientJackson2ObjectMapperFactoryBean in your servlet.xml
<mvc:annotation-driven>
<mvc:message-converters>
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="objectMapper">
<bean class="no.bouvet.jsonclient.spring.JsonClientJackson2ObjectMapperFactoryBean"/>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
This how you solve it using Spring 4 annotation configuration
@Configuration
@ComponentScan("no.bouvet.app")
@EnableWebMvc
public class DispatcherConfig extends WebMvcConfigurerAdapter {
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters){
MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
converter.setObjectMapper(new JsonClientJackson2ObjectMapperFactoryBean().getObject());
converters.add(converter);
super.configureMessageConverters(converters);
}
}
