想把pojo中枚举字段在返回json时直接以里面的descrp字段输出字符串

积分: 360

这家伙很懒，什么个性签名都没有留下。

想把pojo中枚举字段在server @Ok返回json时直接以枚举里面的descrp字段输出字符串，
用了forceString=true和@ToJson，但是未能如愿，应该怎么用？

    @ToJson
    public enum PatrolDirection {
        EAST(1, "东"),
        SOUTH(2, "南"),
        WEST(3, "西"),
        NORTH(4, "北"),
        EAST_SOUTH(12, "东南"),
        SOUTH_WEST(23, "西南"),
        WEST_NORTH(34, "西北"),
        NORTH_EAST(41, "东北");

        public final int patrol_direction;
        public final String descrp;

        PatrolDirection(int patrol_direction, String descrp) {
            this.patrol_direction = patrol_direction;
            this.descrp = descrp;
        }
        
        public String toJson() {
        	log.info("toJson() called !!!!!!!!!!!!!!"); 
        	return getDescrp();
        }
        
        public String toJson(JsonFormat jf) {
        	log.info("toJson() called !!!!!!!!jf!!!!!!"); 
        	return getDescrp();
        }
        
        

        public static PatrolDirection getFromInt(Integer v) {
            if(v==null){
                return PatrolDirection.EAST;
            }

            for(PatrolDirection pt : values()){
                if(pt.patrol_direction==v){
                    return pt;
                }
            }
            return PatrolDirection.EAST;
        }

        public int getValue() {
            return patrol_direction;
        }


        public String getDescrp(){
            return descrp;
        }

        public static PatrolDirection getFromText(String text){
            if(text==null){
                return null;
            }

            for(PatrolDirection pt : values()){
                if(pt.descrp.equals(text)){
                    return pt;
                }
            }
            return null;

        }

@JsonField(forceString=true)
	@Column
	@ColDefine(type=ColType.INT, adaptor=PatrolDirectionAdaptor.class)
    public PatrolDirection patrol_direction; //巡检方向

是报错还是咋了?

它直接输出 SOUTH，期望按自定义输出南
而且 log.info("toJson() called !!!!!!!!!!!!!!"); 并没有被调用

wx_latcg0cou3lvl3g2g3a6 3楼•720天前

server端返回： {"direction":"SOUTH"}

@At("/test")
@Ok("json")
@Filters(@By(type=CrossOriginFilter.class))
public class TestModule {
    @At
    public Object test_direction(HttpServletRequest req) {
    	NutMap re = new NutMap();
    	re.put("direction", PatrolDirection.SOUTH);
    	return re;
    }
}

去掉toJson系列方法试试

wx_latcg0cou3lvl3g2g3a6 5楼•720天前

换个写法，服务端返回 {"data":{"id":0,"patrol_direction":"SOUTH"}}
一样的。

我的nutzboot是 2.4.0.v20200427


@Table("test_tble_xxx")
public class TestBean {
	@Id
	public long id;
	
	@JsonField(forceString=true)
	@Column
	@ColDefine(type=ColType.INT, adaptor=PatrolDirectionAdaptor1.class)
    public PatrolDirection1 patrol_direction; //巡检方向
	
    public static class PatrolDirectionAdaptor1 implements ValueAdaptor {

		@Override
		public Object get(ResultSet rs, String colName) throws SQLException {
			// TODO Auto-generated method stub
			int databaseValue = rs.getInt(colName);
			return PatrolDirection.getFromInt(databaseValue);
		}

		@Override
		public void set(PreparedStatement stat, Object obj, int index) throws SQLException {
			// TODO Auto-generated method stub
			PatrolDirection p = (PatrolDirection) obj;
			stat.setInt(index, p.getValue());
			
		}
    }
}


@At("/test")
@Ok("json")
@Filters(@By(type=CrossOriginFilter.class))
public class TestModule {
    @At
    public Object test_direction(HttpServletRequest req) {
    	NutMap re = new NutMap();
    	TestBean data = new TestBean();
    	data.patrol_direction = PatrolDirection1.SOUTH;
    	re.put("data", data);
    	return re;
    }
}

去掉 toJson 也是一样。它里面的日志都没打印执行

不支持enum？？

我用普通class可以正常输出，但enum有问题：
{"data":{"id":0,"patrol_direction":"SOUTH","patrol_direction2":南}}


@Table("test_tble_xxx")
public class TestBean {
	@Id
	public long id;
	
	@Column
	@ColDefine(type=ColType.INT, adaptor=PatrolDirectionAdaptor1.class)
    public PatrolDirection1 patrol_direction; //巡检方向
	
	@Column
	@ColDefine(type=ColType.MYSQL_JSON)
    public PatrolDirection2 patrol_direction2;
	
    public static class PatrolDirectionAdaptor1 implements ValueAdaptor {

		@Override
		public Object get(ResultSet rs, String colName) throws SQLException {
			// TODO Auto-generated method stub
			int databaseValue = rs.getInt(colName);
			return PatrolDirection.getFromInt(databaseValue);
		}

		@Override
		public void set(PreparedStatement stat, Object obj, int index) throws SQLException {
			// TODO Auto-generated method stub
			PatrolDirection p = (PatrolDirection) obj;
			stat.setInt(index, p.getValue());
			
		}
    }
}
