string2unicode

public static String string2unicode(String str)

unicode2string

public static String unicode2string(String str)

format

public static String format(String str,
                            Object... args)

默认使用 EMPTY_INDEX_MODEL | NUM_INDEX_MODEL | KEY_VALUE_MODEL混合模式。defaultVal = "null"
注：支持嵌套格式（例：aaa{name{msg}}aaa）

参数:

str -

args - 可以传map或者vo对象

返回:

formatMix

public static String formatMix(String str,
                               int model,
                               String defaultVal,
                               Object... args)

多种模式并存时，优先级：KEY_VALUE_MODEL > NUM_INDEX_MODEL
注：支持嵌套格式（例：aaa{name{msg}}aaa）

参数:

str -

model - 三种值得组合：EMPTY_INDEX_MODEL | NUM_INDEX_MODEL | KEY_VALUE_MODEL 具体解释请看常量

defaultVal - 当没有对应的参数或参数为null时，默认代替的值。defaultVal:null - 不做任何值替换；defaultVal:"" - 空字符窜代替；defaultVal:"null" - "null"字符窜代替

args -

返回:

参数:

paramsStr -

enums - 暴露接口方提供的枚举常量值，格式如：{"GENDER": [{"name": "MALE", "value": 0, "describe": "男"}, {"name": "FEMALE", "value": 1, "describe": "女"}]} （name 自己项目枚举名字，value为第三方需要的值）
