这是您的结构：

#!/bin/bash
OUT="GATE1"
COUNT="14"
DATA="CU4 CU2 CU9var CU3 CU1 CU11admin CU10opt not_sy CU_doonce cutttCU clocal_CU global_CU tivoli_CU"
while [[ -n $DATA ]]
do
    printf "%-20s %-5s %-20s \n" "${OUT}" "${COUNT}" "${DATA:0:48}"
    OUT=" "
    COUNT=" "
    DATA="${DATA:48}"
done

要读取rhis json，只需调用public class JsonClass { Coord coord; List<Weather> weather; String base; Main main; Wind wind; Clouds clouds; long dt; Sys sys; int timezone; int id; String name; int cod; private class Coord { private float lon; private float lat; } private class Weather { int id; String main; String description; String icon; } private class Main { float temp; int pressure; ... } private class Wind { float speed; int deg; } private class Clouds { int all; } private class Sys { String country; long sunrise; long sunset; } } ：

readValue

不要忘记添加ObjectMapper MAPPER = new ObjectMapper(); JsonClass jsnClz = MAPPER .readValue(json,JsonClass.class); / getter或使用龙目岛注释。
