一：github地址

• github

需要代理访问，这里面常用的方法和配置

二：依赖

• 核心包

<dependency>
    <groupId>com.mashape.unirest</groupId>
    <artifactId>unirest-java</artifactId>
    <version>1.4.4</version>
</dependency>

• 其他依赖

<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.3.6</version>
</dependency>
<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpasyncclient</artifactId>
  <version>4.0.2</version>
</dependency>
<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpmime</artifactId>
  <version>4.3.6</version>
</dependency>
<dependency>
  <groupId>org.json</groupId>
  <artifactId>json</artifactId>
  <version>20140107</version>
</dependency>

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.11</version>
  <scope>test</scope>
</dependency>

三：初始化配置

• 说明

主要是设置一下超时时间和序列化，如果不设置序列化，
那个Unirest.post().body()中的body不能传递json对象，
针对一些接口会参数缺失。

• 代码

package com.tohours.dwx.config;

import javax.annotation.PostConstruct;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;

import com.fasterxml.jackson.core.JsonProcessingException;
import com.mashape.unirest.http.ObjectMapper;
import com.mashape.unirest.http.Unirest;

/**
 *
 * @author RenJie
 *
 */
@Configuration
public class UnirestConfig {

	@Autowired
	private com.fasterxml.jackson.databind.ObjectMapper mapper;

	@PostConstruct
	public void postConstruct() {
		// 1.0 设置超时时间
		// Unirest默认为10s
		Integer connectionTimeout = 5 * 1000;
		// Unirest默认为60s
		Integer socketTimeout = 20 * 1000;
		Unirest.setTimeouts(connectionTimeout, socketTimeout);

		// 2.0 设置jackjsonMapper，实现unirest序列化
		Unirest.setObjectMapper(new ObjectMapper() {

			public String writeValue(Object value) {
				try {
					return mapper.writeValueAsString(value);
				} catch (JsonProcessingException e) {
					throw new RuntimeException(e);
				}
			}

			public <T> T readValue(String value, Class<T> valueType) {
				try {
					return mapper.readValue(value, valueType);
				} catch (Exception e) {
					throw new RuntimeException(e);
				}
			}
		});
	}
}
