2.接口可視化
2.1 瀏覽器打開地址： http://localhost:8080/easy-swagger
2.2 調試接口
2.2.1 調用方接口
2.2.2 被調用接口
2.3 接口代碼
package com.zlyx.easy.start.controller;
import java.util.Map;
import com.zlyx.easy.core.loggers.Logger;
import com.zlyx.easy.core.model.ResultModel;
import com.zlyx.easy.core.utils.HttpUtils.HttpClient;

/**

*/
@SpringController(value = "/test", todo = { "easy-http接口使用示例" })
public class HttpTestController {
/**
* 被調用的http接口
*
* @param params
* @return
*/
@SpringMapping(value = "service", todo = "被調用的HTTP接口")
public ResultModel<Map<String, String>> service(String id, String name, int age) {
return ResultModel.success(RequestUtils.getParamsMap());
}
/**

*/
@SpringMapping(value = "callService", todo = "調用方HTTP接口")
public HttpResponse callService(String id, String name, int age) {
String url = "http://localhost:8080/test/service";
try {
return HttpClient.url(url).param("id", id).param("name", name).param("age", age).post();
} catch (Exception e) {
Logger.err(e.getMessage(), e);
return HttpResponse.failure(e);
}
}
}
3.玩轉easy-http
3.1 客戶端編程示例（POST）
3.1.1 客戶端代碼
package com.zlyx.easy.start.test;
import com.zlyx.easy.core.utils.HttpUtils.HttpClient;
import com.zlyx.easy.core.utils.OptUtils;
public class HttpTest {
public static void main(String[] args) throws Exception {
String id = OptUtils.randomUUID();
String name = id + "_" + OptUtils.getMillis();
int age = OptUtils.randomNum();
String url = "http://localhost:8080/test/service";
HttpClient.url(url).param("id", id).param("name", name).param("age", age).put();
}
}
PS：需要修改SpringMapping註解的method值，默認爲post。

3.2 客戶端編程示例（GET）
3.2.1 客戶端代碼
package com.zlyx.easy.start.test;
import com.zlyx.easy.core.utils.HttpUtils.HttpClient;
import com.zlyx.easy.core.utils.OptUtils;
public class HttpTest {
public static void main(String[] args) throws Exception {
String id = OptUtils.randomUUID();
String name = id + "_" + OptUtils.getMillis();
int age = OptUtils.randomNum();
String url = "http://localhost:8080/test/service";
HttpClient.url(url).param("id", id).param("name", name).param("age", age).get();
}
}

4.接口式編程
4.1 HttpTestService
package com.zlyx.easy.start.http;
import org.springframework.web.bind.annotation.PostMapping;
import com.zlyx.easy.core.utils.HttpUtils.HttpResponse;
import com.zlyx.easy.http.annotations.HttpService;
@HttpService(value = "http://localhost:8080/")
public interface HttpTestService {
@PostMapping("/test/service")
public HttpResponse callService(String name, String id, int age);
}
4.2 HttpServiceController
package com.zlyx.easy.start.controller;
import org.springframework.beans.factory.annotation.Autowired;
import com.zlyx.easy.core.utils.HttpUtils.HttpResponse;
import com.zlyx.easy.start.http.HttpTestService;
import com.zlyx.easy.swagger.annotations.SpringController;
import com.zlyx.easy.swagger.annotations.SpringMapping;
/**
* Http測試接口
*
* @Auth 趙光
* @Describle
* @2019年1月3日 下午2:54:41
*/
@SpringController(value = "/http", todo = { "easy-http使用示例" })
public class HttpServiceController {
@Autowired
private HttpTestService httpTestService;
/**
* 調用方http接口
*
* @param params
* @return
*/
@SpringMapping(value = "service", todo = "調用方HTTP接口")
public HttpResponse callService(String id, String name, int age) {
return httpTestService.callService(name, id, age);
}
}

5.easy-http接口式編程原理
5.1 聲明一個註解
package com.zlyx.easy.http.annotations;
import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import org.springframework.stereotype.Component;
/**
* Http服務接口註解
*
* @Auth 趙光
* @Describle
* @2019年12月25日
*/
@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
@Component
public @interface HttpService {
/**
* 服務端域名或IP+端口
*
* @return
*/
String value();
}
5.2 接口上使用
package com.zlyx.easy.start.http;
import org.springframework.web.bind.annotation.PostMapping;
import com.zlyx.easy.core.utils.HttpUtils.HttpResponse;
import com.zlyx.easy.http.annotations.HttpService;
@HttpService(value = "http://localhost:8080/")
public interface HttpTestService {
@PostMapping("/test/service")
public HttpResponse callService(String name, String id, int age);
}
5.3 實現easy-core封裝後的自動配置接口，在execute(）方法中完成後續調用鏈
package com.zlyx.easy.http.dispatch;
import java.lang.reflect.Method;
import org.springframework.beans.factory.annotation.Autowired;
import com.zlyx.easy.core.factory.FactoryBeanConfigurer;
import com.zlyx.easy.core.factory.defaults.annotations.FactoryBean;
import com.zlyx.easy.core.factory.interfaces.FactoryBeanDefiner;
import com.zlyx.easy.core.spring.SpringUtils;
import com.zlyx.easy.http.annotations.HttpService;
import com.zlyx.easy.http.exceptions.MappingHandlerException;
import com.zlyx.easy.http.handlers.AbstractMappingHandler;
import com.zlyx.easy.http.models.RequestModel;
import com.zlyx.easy.http.parser.HttpMethodParser;
import com.zlyx.easy.http.parser.defaults.DefaultHttpMethodParser;
/**
* 請求路由
*
* @Auth 趙光
* @Describle
* @2019年12月25日
*/
@FactoryBean(annotationClass = HttpService.class, todo = "請求轉發")
public class HttpMappingDispatcher implements FactoryBeanDefiner {
@Autowired(required = false)
private HttpMethodParser httpMethodParser;
@Override
public Object excute(Class<?> proxyClass, Method method, Object[] args) throws Exception {
RequestModel rm = httpMethodParser.parse(proxyClass, method, args);
rm.setBaseUrl(SpringUtils.getProperty(rm.getBaseUrl()));
if (rm.getUrl() == null) {
throw new MappingHandlerException("請求地址不能爲空!");
}
if (rm.getMethod() == null) {
throw new MappingHandlerException("請求方式不能爲空!");
}
return AbstractMappingHandler.call(rm);
}
@Override
public void afterPropertiesSet() throws Exception {
FactoryBeanConfigurer.addFactoryBeanHandler(this);
if (httpMethodParser == null) {
this.httpMethodParser = new DefaultHttpMethodParser();
}
}
}
