微服务Feign相关杂记
1 各个微服务有自己的token，如何调用免除微服务之前的token，但不能影响每个服务自身的token校验机制呢？
解决方案两个步骤
步骤之一:在feignclient中增加自定义标识头
headers = {"ContentType=application/x-www-form-urlencoded","OutToken=true"}
@PostMapping(value = "/hardware/getbuildNuListByAreaId",headers = {"ContentType=application/x-www-form-urlencoded","OutToken=true"})
public Result> getbuildNuListByAreaId(
@RequestParam(name = "houseAreaId", required = true) String houseAreaId,
@RequestParam(name = "pageSize", required = false, defaultValue = "10") Integer pageSize,
@RequestParam(name = "pageNo", required = false, defaultValue = "1") Integer pageNo); 步骤二在切面中过滤拦截限制
//如果是FeignClient调用那么直接过滤掉token,OutToken为外部调用是否放行,true放行,false不放行
String OutToken = request.getHeader("OutToken");
if(StringUtils.equals(OutToken,"true")){//放行
return point.proceed();
}

@Aspect

public class DeviceAuthTokenAspect {
@Autowired

/**

@Pointcut("@annotation(org.jeecg.common.aspect.annotation.DeviceAuthToken)")

@Around("pointCut()")

boolean value = pd.value();
if(!value){
return point.proceed();
}
// 将token信息放入header中

if(token==null || "".equals(token)){
token = request.getParameter("unique");
}
if(token==null || "".equals(token)){
throw new JeecgBootException(YyResultCodeVsMsgConstant.DEVICE_TOKEN_IS_NULL_CODE+ ":" + YyResultCodeVsMsgConstant.DEVICE_TOKEN_IS_NULL_MSG);
}

}
}
}
return point.proceed();
}
}
2 微服务表单对象传递，数据丢失
解决方案增加@SpringQueryMap
@PostMapping(value = "/hardware/switchLight",headers = {"ContentType=application/x-www-form-urlencoded","OutToken=true"})
public Result switchLight(@SpringQueryMap SwitchLightDto dto);3 微服务multipart/form-data混合表单传参解析不了
解决步骤:
步骤一:在FeignClient中增加如下
consumes = MediaType.MULTIPART_FORM_DATA_VALUE
/**
* 文件上传
* @return
* @throws Exception
*/
@PostMapping(value = "/property/upload",consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public Result upload(@RequestParam(value = "biz",required = false ,defaultValue = "temp")String biz,
@RequestPart(value = "file",required = true)MultipartFile file) throws Exception ;
步骤二：具体的接口也增加
@PostMapping(value = "property/upload",consumes = MediaType.MULTIPART_FORM_DATA_VALUE) public Result upload(@RequestParam(value = "biz",required = false ,defaultValue = "temp")String biz, @RequestPart(value = "file",required = true)MultipartFile file) throws Exception {}
4 微服务分页问题
调用方不能用interface类
public class Pageimplements IPage {
微服务方
@PostMapping(value = "/hardware/getHouseAreaListByPca",headers = {"ContentType=application/x-www-form-urlencoded","OutToken=true"})
public Result> getHouseAreaListByPca(
@RequestParam(name = "pca", required = true) String pca,
@RequestParam(name = "pageSize", required = false, defaultValue = "10") Integer pageSize,
@RequestParam(name = "pageNo", required = false, defaultValue = "1") Integer pageNo);
调用方
@ApiOperation(value = "根据省市区获取当前小区信息", notes = "根据省市区获取当前小区根据省市区获取当前小区信息")
@PostMapping(value = "/getHouseAreaListByPca")
@ApiImplicitParams({
@ApiImplicitParam(paramType = "query", dataType = "String", name = "pcaId", value = "省市区编号", required = true),
@ApiImplicitParam(paramType = "query", dataType = "Integer", name = "pageSize", defaultValue = "10", value = "每页条数", required = false),
@ApiImplicitParam(paramType = "query", dataType = "Integer", name = "pageNo", defaultValue = "1", value = "当前页", required = false),
})
public Result> getHouseAreaListByPca(
@RequestParam(name = "pcaId", required = true) String pcaId,
@RequestParam(name = "pageSize", required = false, defaultValue = "10") Integer pageSize,
@RequestParam(name = "pageNo", required = false, defaultValue = "1") Integer pageNo) {
Result> houseAreaListByPca = sysBaseAPI.getHouseAreaListByPca(pcaId, pageSize, pageNo);
return houseAreaListByPca;
}
5 多类目分类
@Data
public class RepairTypeVo implements Serializable {
@ApiModelProperty(value = "维修类型(1住宅报修,2公共报修)")
private Integer maintainType;
@ApiModelProperty(value = "id")
private String id;
@ApiModelProperty(value = "维修设施")
private String name;
public RepairTypeVo(Integer maintainType, String id, String name) {
this.maintainType = maintainType;
this.id = id;
this.name = name;
}
}
public static void main(String args[]) {
List list2=new ArrayList();
list2.add(new RepairTypeVo(1,"1","name"));
list2.add(new RepairTypeVo(2,"5","name5"));
list2.add(new RepairTypeVo(3,"4","name2"));
list2.add(new RepairTypeVo(1,"1","name7"));
Map> collect =
list2.stream().collect(Collectors.groupingBy(RepairTypeVo::getMaintainType));
System.out.println(new Gson().toJson(collect));
}
{
- "1":[
],
- {
},
- "maintainType":1,
- "id":"1",
- "name":"name"
- {
}
- "maintainType":1,
- "id":"1",
- "name":"name7"
- "2":[
],
- {
}
- "maintainType":2,
- "id":"5",
- "name":"name5"
- "3":[
]
- {
}
- "maintainType":3,
- "id":"4",
- "name":"name2"
}
前端页面边界去重
/**
* 从diff中找出main中没有的元素
* @param main
* @param diff
* @return
*/
private List getDiff(String main,String diff){
if(oConvertUtils.isEmpty(diff)) {
return null;
}
if(oConvertUtils.isEmpty(main)) {
return Arrays.asList(diff.split(","));
}
String[] mainArr = main.split(",");
String[] diffArr = diff.split(",");
Map map = new HashMap<>();
for (String string : mainArr) {
map.put(string, 1);
}
List res = new ArrayList();
for (String key : diffArr) {
if(oConvertUtils.isNotEmpty(key) && !map.containsKey(key)) {
res.add(key);
}
}
return res;
