STR是一个StringTemplate.Processor<String, RuntimeException> 类型的字段,它的功能也很简单,按顺序拼装好字符串并返回,也就是最常见的字符串模板的功能。 而StringTemplate.Processor定义如下: public interface Processor<R, E extends Throwable> { R process(StringTemplate stringTemplate) throws E; // ... 还...
publicclassStringInterpolation{publicstaticvoidmain(String[]args){// Step 1: 定义字符串模板,其中包含占位符Stringtemplate="你好, %s!你今年 %d 岁了。";// Step 2: 定义要填充的实际值Stringname="小白";intage=20;// 使用 String.format() 来格式化字符串Stringresult=String.format(template,name,age);...
1. What is a String Template? Template string is a familiar feature that is present in most programming languages such astypescript template stringsor angular interpolation. Basically, we embed the variables into a String and the values of the variables are resolved in runtime. Thus template str...

3. String Concatenation vs String Templates Since Java 21, String templates provide the interpolation-like capabilities to Java strings. We can place variables and expressions into Strings that are evaluated and replaced in runtime. In runtime, String concatenation and Sprint templates generate mostly...

此外,开发人员还可以创建自己的模板处理器,用于模板表达式的处理。模板处理器是一个提供ValidatingProcessor功能接口的对象,它的类实现了ValidatingProcessor的单一抽象方法。该方法接受StringTemplate并返回一个对象。自定义模板处理器让开发人员可以在运行时执行验证并返回任何类型的对象,而不仅仅是字符串。

checkResource 方法做了两件事,第一件事是判断 Resource 当中的 url 是否为空,也就是判断是否存在 resource,如果 url 都没东西,那么后续的模板引擎加载就更不用说了;第二件事是进行 template 的获取,也可以把这理解为准备开始做模板引擎加载的业务了。
