状态码表对应数据返回

1.创建注解类

package com.panda.emo.commons.annotations;

import java.lang.annotation.*;

@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface OperDict {
    /**
     * 列名 ，返回map中的key，多个以，分隔
     * @return
     */
    String columns();

    String operKey();

    String newKeys();
}
2./**

 * 切面操作
 *
 * @Author Zhou
 * @Date 2019/12/1315:07
 */
@Component
@Aspect
public class OperateAspect {
    @Resource
    private OperateDao operateDao;

    @Pointcut("@annotation(com.panda.emo.commons.annotations.OperDict)")       //内外部状态码表切点
    public void pointDict() {}

    @AfterReturning(pointcut = "pointDict()", returning = "oper")
    public void daoReturn(JoinPoint point, Object oper) {
        if (oper == null)
            return;
        try{
            if (Map.class.isAssignableFrom(oper.getClass())) {
                processAnnotation(point,(Map<String, Object>) oper);
            } else {
                if (List.class.isAssignableFrom(oper.getClass())) {
                    List os = (List) oper;
                    for (Object o : os) {
                        daoReturn(point, o);
                    }
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
            TLog.println("error:" + e.getMessage());
        }
    }
    private void processAnnotation(JoinPoint point, Map<String, Object> oper) throws Exception {
        if (oper.isEmpty())
            return;
        Annotation[] ans = AOPUtil.getQueryMethodAnnotations(point);

        OperDict operDict = AOPUtil.getAnnotation(OperDict.class, ans);
        processDataDict(operDict, oper);
    }
    private void processDataDict(OperDict operDict, Map<String, Object> oper) throws Exception {
        if (operDict == null)
            return;
        String[] columns = operDict.columns().split(",");
        String[] operKeys = operDict.operKey().split(",");
        String[] newKeys = operDict.newKeys().split(",");
        for (int i=0;i<columns.length;i++){
            String column=columns[i];
            Object value = oper.get(column);
            if (value == null)
                continue;
            String newKey = newKeys[i];
            if (oper.containsKey(newKey)) {
                throw new Exception(newKey + "已经在结果集中存在");
            }
            String code = value.toString();
            String operKey = operKeys[i];
            String name = OperDictionary.getName(operKey, code);
            oper.put(newKey, name);
        }
    }

3.创建.json文件

{
  "status":{
    "name":"内部状态",
    "items": [
      {
        "code": "0",
        "name": "待提交"
      },
      {
        "code": "1",
        "name": "已提交待客户经理审 "
      },
      {
        "code": "2",
        "name": "客户经理已审"
      },
      {
        "code": "3",
        "name": "客户经理驳回"
      },
      {
        "code": "4",
        "name": "内审被驳回"
      },
      {
        "code": "5",
        "name": "内审拒绝"
      },
      {
        "code": "6",
        "name": "内审通过"
      },
      {
        "code": "7",
        "name": "预审中"
      },
      {
        "code": "8",
        "name": "复审中"
      },
      {
        "code": "9",
        "name": "已完成"
      }
    ]
  }
}
4.解析json文件的类

public class OperDictionary {
    private static String oper;
    private static Map<String,Object> opers;

    public static void init(){
        oper=Application.readPackageFile(OperDictionary.class,"oper.json");
        opers=JSONUtil.toObjectMap(oper);
    }

    public static Map<String,Object> get(String key){
        return (Map<String,Object>) opers.get(key);
    }

    public static Map<String,Object> allOper(){
        return opers;
    }

    public static String getName(String key,String code){
        Map<String, Object> data = get(key);
        System.out.println(get(key).getClass().getName());
        List<Map<String, Object>> items = (List<Map<String, Object>>) data.get("items");
        for (Map<String, Object> item : items) {
            String cv = (String) item.get("code");
            if (cv.equals(code)) {
                return (String) item.get("name");
            }
        }
        return "";
    }

   public static String operToString(){
        return oper;
   }
