String轉Map集合

1.參數類型  {key=value, key=value, key=value}

2.轉為Map<String,String>

2.1常規寫法

private Map<String,String> sendStringToMap(String send){

String strip = StringUtils.strip(send, "{}");
String[] split = strip.split(",");
List<String> list = Arrays.asList(split); 
return list.stream().map(item -> item.split("=")).collect(Collectors.toMap(i -> i[0].trim(), i -> i[1]));

}

2.2簡潔寫法

private Map<String,String> sendStringToMap(String send){
    return Arrays.stream(
           StringUtils.strip(send, "{}")
           .split(",")).map(item -> item.split("=")).collect(Collectors.toMap(i -> i[0].trim(), i -> i[1]));
}

 

3.用到的包（StringUtils）

<dependency>
    <groupId>commons-lang</groupId>
    <artifactId>commons-lang</artifactId>
    <version>2.6</version>
</dependency>
