带jsk证书，请求https接口

首先是三个返回的实体类

BaseVo.java

package https2;

import java.io.Serializable;
import java.lang.reflect.InvocationTargetException;
import java.util.ArrayList;
import java.util.List;

public class BaseVo implements Serializable {

	private static final long serialVersionUID = 1L;

	public List<String> getField(Object model) {
		List<String> list = new ArrayList<String>();

		java.lang.reflect.Method[] method = model.getClass().getDeclaredMethods();// 获取对象所有方法
		for (java.lang.reflect.Method m : method) {

			if (m.getName().startsWith("get")) {// 获取get方法
				Object o = null;
				try {
					o = m.invoke(model);
				} catch (IllegalAccessException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				} catch (IllegalArgumentException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				} catch (InvocationTargetException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}// 执行
				if (o == null ) {
					list.add("");
				} else {
					list.add(o.toString());
				}
			}
		}
		return list;
	}
}

PageVo.java

package https2;

public class PageVo extends BaseVo {
	/**
	 *
	 */
	private static final long serialVersionUID = 1L;
	private int current=1;//当前第几页
	private int currentNum=1;//当前第几页
	private int total;//总数
	private int pages;//页数
	private int number = 15;//每页多少条
	private String column;
	private String order;

	public int getCurrentNum() {
		return currentNum;
	}

	public String getColumn() {
		return column;
	}
	public void setColumn(String column) {
		this.column = column;
	}
	public String getOrder() {
		return order;
	}
	public void setOrder(String order) {
		this.order = order;
	}
	public int getNumber() {
		return number;
	}
	public void setNumber(int number) {
		this.number = number;
	}
	public int getCurrent() {
		return current;
	}
	public void setCurrent(int current) {
		this.current = current;
		this.currentNum = current;
	}
	public int getTotal() {
		return total;
	}
	public void setTotal(int total) {
		this.total = total;
		if(this.total%this.number==0){
			this.pages = this.total / this.number;
		}else{
			this.pages = this.total / this.number + 1;
		}
	}
	public int getPages() {
		return pages;
	}
	public void setPages(int pages) {
		this.pages = pages;
	}

}

ResultVo.java

package https2;

public class ResultVo extends BaseVo{
	/**
	 *
	 */
	private static final long serialVersionUID = 1L;

	private String code;
	private String msg;
	private Object data;
	private PageVo page;

	public PageVo getPage() {
		return page;
	}
	public void setPage(PageVo page) {
		this.page = page;
	}
	public String getCode() {
		return code;
	}
	public void setCode(String code) {
		this.code = code;
	}
	public String getMsg() {
		return msg;
	}
	public void setMsg(String msg) {
		this.msg = msg;
	}
	public Object getData() {
		return data;
	}
	public void setData(Object data) {
		this.data = data;
	}

}

然后是一个工具类

package https2;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLSession;

public class HostnameVerifierUtil implements HostnameVerifier {

	@Override
	public boolean verify(String hostname, SSLSession arg1) {
		if("localhost".equals(hostname)){
            return true;
        } else {
            return false;
        }
	}

}

最后是https请求工具类

package https2;

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.security.GeneralSecurityException;
import java.security.KeyStore;  

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.KeyManagerFactory;
import javax.net.ssl.SSLContext;

     */
    public static KeyStore getKeyStore(String password, String keyStorePath)
            throws Exception {

        // 获得密钥库文件流
        FileInputStream is = new FileInputStream(keyStorePath);
        // 加载密钥库
        ks.load(is, password.toCharArray());
        // 关闭密钥库文件流
        is.close();
        return ks;
    }  

    /**

     */
    public static SSLContext getSSLContext(String password,
            String keyStorePath, String trustStorePath) throws Exception {

        // 实例化信任库
        TrustManagerFactory trustManagerFactory = TrustManagerFactory

        SSLContext ctx = SSLContext.getInstance("TLS");
        // 初始化SSL上下文
        ctx.init(keyManagerFactory.getKeyManagers(),
                trustManagerFactory.getTrustManagers(), null);
        // 获得SSLSocketFactory

    }
