限定符和类型	方法和说明
Splitter	limit(int limit) 拆分后集合最大保留长度, 返回的集合List.size()可能小于等于limit但是不会大于limit String str1 = "1,2,3,4,5,"; List<String> list1 = Splitter.on(',').limit(3).splitToList(str1); // 结果: ["1","2","3"] String str2 = "1,2"; List<String> list1 = Splitter.on(',').limit(5).splitToList(str1); // 结果: ["1","2"] 注意: 如果List.size()已达到limit限制, 剩余字符串将不在加入集合中
static Splitter	on(char separator) 返回一个以指定字符的分割器
static Splitter	on(java.lang.String separator) 返回一个以指定字符的分割器
java.lang.String[]	split(java.lang.CharSequence str) 字符串分割 样例: Splitter.on(',').split("1,2,3"); 结果:["1","2","3"]
java.util.List<java.lang.String>	splitToList(java.lang.CharSequence str) 字符串分割 样例: Splitter.on(',').splitToList("1,2,3"); 结果:["1","2","3"]
java.util.stream.Stream<java.lang.String>	splitToStream(java.lang.CharSequence str) 字符串分割 样例: Splitter.on(",").split("1,2,3"); 结果:["1","2","3"]
Splitter.MapSplitter	withKeyValueSeparator(char separator) 获取一个MapSplitter分割器,将指定字符串分割为Map 样例: String str = "page=1&pageSize=10&name=zhangsan&age=18"; Map<String, String> split = Splitter.on("&").withKeyValueSeparator("=").split(str); 结果:{"page":"1","pageSize":"10","name":"zhangsan","age":"18"}
Splitter.MapSplitter	withKeyValueSeparator(java.lang.String separator) 获取一个MapSplitter分割器,将指定字符串分割为Map 样例: String str = "page=1&pageSize=10&name=zhangsan&age=18"; Map<String, String> split = Splitter.on("&").withKeyValueSeparator("=").split(str); 结果:{"page":"1","pageSize":"10","name":"zhangsan","age":"18"}

方法详细资料

on

public static Splitter on(java.lang.String separator)

返回一个以指定字符的分割器

参数:

separator - 指定分割字符串

返回:

Splitter

on

public static Splitter on(char separator)

返回一个以指定字符的分割器

参数:

separator - 指定分割字符

返回:

Splitter

limit

public final Splitter limit(int limit)

拆分后集合最大保留长度, 返回的集合List.size()可能小于等于limit但是不会大于limit

 String str1 = "1,2,3,4,5,";
 List<String> list1 = Splitter.on(',').limit(3).splitToList(str1);
 // 结果: ["1","2","3"]
 String str2 = "1,2";
 List<String> list1 = Splitter.on(',').limit(5).splitToList(str1);
 // 结果: ["1","2"]
 

注意: 如果List.size()已达到limit限制, 剩余字符串将不在加入集合中

参数:

limit - 拆分后集合最大长度, 必须大于0

返回:

Splitter

抛出:

java.lang.UnsupportedOperationException - limit小于或等于0时抛出,或者已经设置过limit值再次设置会抛出异常

从以下版本开始:

1.0.7

splitToList

public final java.util.List<java.lang.String> splitToList(java.lang.CharSequence str)

字符串分割
样例:
Splitter.on(',').splitToList("1,2,3");
结果:["1","2","3"]

参数:

str - 待分割字符串

返回:

分割后字符串集合, ArrayList集合

split

public final java.lang.String[] split(java.lang.CharSequence str)

字符串分割 样例: Splitter.on(',').split("1,2,3"); 结果:["1","2","3"]

参数:

str - 待分割字符串

返回:

分割后字符串数组

splitToStream

public final java.util.stream.Stream<java.lang.String> splitToStream(java.lang.CharSequence str)

字符串分割 样例: Splitter.on(",").split("1,2,3"); 结果:["1","2","3"]

参数:

str - 待分割字符串

返回:

分割后的字符串

withKeyValueSeparator

public final Splitter.MapSplitter withKeyValueSeparator(java.lang.String separator)

获取一个MapSplitter分割器,将指定字符串分割为Map 样例: String str = "page=1&pageSize=10&name=zhangsan&age=18"; Map<String, String> split = Splitter.on("&").withKeyValueSeparator("=").split(str); 结果:{"page":"1","pageSize":"10","name":"zhangsan","age":"18"}

参数:

separator - 第二次拆分的标记字符串,对应上面样例代码中的=字符

返回:

MapSplitter

withKeyValueSeparator

public final Splitter.MapSplitter withKeyValueSeparator(char separator)

获取一个MapSplitter分割器,将指定字符串分割为Map 样例: String str = "page=1&pageSize=10&name=zhangsan&age=18"; Map<String, String> split = Splitter.on("&").withKeyValueSeparator("=").split(str); 结果:{"page":"1","pageSize":"10","name":"zhangsan","age":"18"}

参数:

separator - 第二次拆分的标记字符

返回:

MapSplitter
