c:out escapeXml 是否转义 true 转义(> <) false 不转义
<c:set target=‘${user}‘ property=‘uuid‘ value=‘1111‘></c:set> javaBean赋值
<c:set var=‘aaa‘ value="11111" scope="request"/> 给一个变量赋值

4、fn:escapeXml(string) → String
5、fn:indexOf(string, substring) → int
6、${fn:join(paramValues.type, ",")}
7、fn:length(input) → integer
8、fn:replace(inputString, beforeSubstring, afterSubstring) → String
9、fn:split(string, delimiters) → String[]
10、fn:startsWith(string, prefix) → boolean
11、fn:substring(string, beginIndex, endIndex) → String
12、fn:trim(string) → String
