An alternative to transforming the string on the server is to let CSS do the work:
在服务器上转换字符串的另一种方法是让 CSS 来完成这项工作:

An idea:
一个想法:
In a class, create a simple method that uses the WordUtils from Apache Commons Lang that will manipulate your String:
在一个类中,创建一个简单的方法,该方法使用来自 Apache Commons Lang 的 WordUtils 来操作您的字符串:
import org.apache.commons.lang.WordUtils;
...
public static String titleCase(String input){
return WordUtils.capitalize(input);;
}
And now, create your own tag (in a function.tld) :
现在,创建您自己的标签(在 function.tld 中):
<?xml version="1.0" encoding="UTF-8" ?>
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
version="2.0">
<description>functions library</description>
<display-name>functions</display-name>
<tlib-version>1.1</tlib-version>
<short-name>xfn</short-name>
<uri>http://yourdomain/functions.tld</uri>
<function>
<description>
Title case a String
</description>
<name>titleCase</name>
<function-class>Functions</function-class>
<function-signature>java.lang.String titleCase(java.lang.String)</function-signature>
<example>
${xfn:titleCase(string)}
</example>
</function>
</taglib>

It's not too super hard in JSTL...
在 JSTL 中并不太难...
${fn:toUpperCase(fn:substring(user.firstName, 0, 1))}${fn:toLowerCase(fn:substring(user.firstName, 1, -1))}
