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;
}
}
}
