使用Spring MVC搭建参数加解密服务

1.编写Service接口层

package com.csj2018.o2o.service;

public interface YYGHParamService {
	String encrypt(String param,String device) throws Exception;
	String decrypt(String param,String device) throws Exception;
}

2.实现Service接口实现层

package com.csj2018.o2o.service.impl;

import java.net.URLDecoder;
import java.net.URLEncoder;
import java.util.Map;

import org.springframework.stereotype.Service;

import com.csj2018.o2o.service.YYGHParamService;
import com.csj2018.o2o.util.DESUtil;
@Service
public class YYGHParamServiceImpl implements YYGHParamService{
	
	@Override
	public String encrypt(String param,String device) throws Exception  {
		String url;
		if(device.equalsIgnoreCase("android")) {
			//android
			System.out.println("android加密");
            url = DESUtil.encryptDES(param);
		}else if(device.equalsIgnoreCase("ios")) {
			//iOS
			System.out.println("iOS加密");
            url = URLEncoder.encode(DESUtil.encryptDES(param),"utf-8");
		}else {
			//js
			System.out.println("URL编码");
            url = URLEncoder.encode(param,"utf-8");
		}
		return url;
	}
	@Override
	public String decrypt(String param,String device) throws Exception {
		String url;
		String str;
		if(device.equalsIgnoreCase("android")) {
			//android
			System.out.println("安卓解密");

            url = DESUtil.decryptDES(param);
		}else if(device.equalsIgnoreCase("ios")) {
			//iOS
			str = URLDecoder.decode(param, "UTF-8");
            url = DESUtil.decryptDES(str);
            System.out.println("iOS解密");
		}else {
			//js
			url = URLDecoder.decode(param,"utf-8");
            System.out.println("URL解码");
		}
		return url;
	}
}

单元测试

package com.csj2018.o2o.service;

import org.junit.Ignore;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.csj2018.o2o.BaseTest;
import com.csj2018.o2o.service.YYGHParamService;
import com.csj2018.o2o.service.impl.YYGHParamServiceImpl;


public class YYGHParamServiceTest extends BaseTest{
	
	@Autowired
	private YYGHParamService paramService;
	
	@Test
	public void testdecrpyt() {
		//解密
		try {
			String encypted = "u%2BTLvOADdiYXfbaCgtjeYjLQvRncV%2BTZuopJiVKLlu%2BwrMwdOy%2FaBIShXR3IAMFhy1JFV8Yui5HGrd7%2BEeOM7c3%2Bb9akoIO%2F%2BzzxBc8y%2F224C%2FWGOGiFh4I1RBrRHUYhFo292BpqBBiR0F%2BX4f%2FHhsH9Hw7IKZSFOeP%2FGL3BzSAkGSqk215Pqmj8RlYK3oZidEhS31VwT4CrkeyJlc18i7MzJWHbBGjACHFKfMsBEpIq9uzypJUEH1IyR9z51OpbTFG9skDZ6YZedVOD2%2F%2FWb%2FPJOaZ96f8Mref0d3ejXJ5ZooBeNXWvGA%3D%3D";
			String result = paramService.decrypt(encypted, "android");
			System.out.println(result);
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	@Test
	public void testencrpyt() {
        //加密
		String param = "{"siteRequests":[{"siteNo":"app_ask_banner"},{"siteNo":"app_expert_ask_list_ad"}]}";
		try {
			String result = paramService.encrypt(param, "android");
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}

3.编写Controller层

package com.csj2018.o2o.web.shopadmin;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import com.csj2018.o2o.entity.Area;
import com.csj2018.o2o.entity.Param;
import com.csj2018.o2o.service.AreaService;
import com.csj2018.o2o.service.YYGHParamService;
import com.csj2018.o2o.util.HttpServletRequestUtil;
import com.csj2018.o2o.web.superadmin.AreaController;
import com.fasterxml.jackson.databind.ObjectMapper;

@Controller
@RequestMapping("/superadmin")
public class Getparam {
	Logger logger = LoggerFactory.getLogger(AreaController.class);
    @Autowired
    private YYGHParamService paramService;
    /**
     * 解密
     * @param request 
     * @return 
     */
    @RequestMapping(value="/decrypt", method=RequestMethod.POST)
    @ResponseBody
    private Map<String, Object> getYYGHParamDecrypt(@RequestBody Map<String,String> request){
    	Map<String,Object> modelMap = new HashMap<>();
    	try {
    		String param = request.get("param");
    		String device = request.get("device");
    		String decrypt = paramService.decrypt(param,device);
    		modelMap.put("decrypt", decrypt);
    		logger.info("->解密内容："+param);
    		logger.info("->解密结果："+decrypt);
    		modelMap.put("success", "true");
    		return modelMap;
    	}catch (Exception e) {
    		modelMap.put("success", "false");
    		modelMap.put("errMsg", e.getMessage());
    		return modelMap;
    	}
    }
    /**
     * 加密
     * @param request
     * @return
     */
    @RequestMapping(value="/encrypt", method=RequestMethod.POST)
    @ResponseBody
    private Map<String, Object> getYYGHParamEncrypt(@RequestBody Map<String,String> request){
    	Map<String,Object> modelMap = new HashMap<>();
    	try {
    		String param = request.get("param");
    		String device = request.get("device");
    		String encrypt = paramService.encrypt(param,device);
    		modelMap.put("encrypt", encrypt);
    		logger.info("->加密内容"+param);
    		logger.info("->加密结果："+encrypt);
    		modelMap.put("success", "true");
    		return modelMap;
    	}catch (Exception e) {
    		modelMap.put("success", "false");
    		modelMap.put("errMsg", e.getMessage());
    		return modelMap;
    	}
    }
}

4.前端实现
