freemarker 中的连接字符串
Concatenation strings in freemarker
如何在 freemarker 中连接字符串?
这行不通。
<#function foo input>
<#local str="Hello ">
${str} = ${str} + ${" world"}
<#return str>
</#function>
${foo("a")}

编辑:为了清楚起见,我需要将它与变量一起使用,以便能够编写这样的内容。
public String sayHello() {return "Hello";}
public String sayWorld() {return "world"};
public String sayPeople() {return "people";}
public void main() {
String str = "";
str += sayHello();
str += "";
str += sayWorld();
str += "";
str += sayPeople();
return str;
}
喜欢<#return "Hello " + input + "!">
,或<#return "Hello ${input}!">
。如果您尝试在 #function
内打印输出(与 #macro
内相反),它将被忽略。
编辑:与添加的 Java 示例类似:
<#function concatDemo>
<#local str = "">
<#local str += sayHello()>
<#local str += " ">
<#local str += sayWorld()>
<#local str += "!">
<#return str>
</#function>
<#function sayHello><#return "Hello"></#function>
<#function sayWorld><#return "World"></#function>
${concatDemo()}
