英文:
Using an enum within a nested class with Thymeleaf and Spring Boot
问题
我有以下的类：
Types.java：
```java
public class Types {
public static class PC {
public static enum Motherboard {
OPTION1("选项1"),
OPTION2("选项2"),
OPTION3("选项3");
private final String displayValue;
private Motherboard(String displayValue) { this.displayValue = displayValue; }
public String getDisplayValue() { return this.displayValue; }
}
}
}
在我的 Thymeleaf 模板中我有：
<select name="select-motherboard">
<option th:each="size : ${T(jre.maintainme.utils.strings.Types.PC.Motherboard).values()}" th:value="${size}" th:text="${size.displayValue}"></option>
</select>
然而，这似乎不起作用。然而，如果我将 Motherboard 枚举放入 Types 类中，它会起作用…… 我是否漏掉了一种将枚举嵌套在类中并在 Thymeleaf 中使用它们的方法？

I have the following class:
Types.java:
public class Types {
public static class PC {
public static enum Motherboard {
OPTION1("option 1"),
OPTION2("option 2"),
OPTION3("option 3");
private final String displayValue;
private Motherboard(String displayValue) { this.displayValue = displayValue; }
public String getDisplayValue() { return this.displayValue; }
}
};
};
In my Thymeleaf template I have:
<select name="select-motherboard">
<option th:each="size : ${T(jre.maintainme.utils.strings.Types.PC.Motherboard).values()}" th:value="${size}" th:text="${size.displayValue}"></option>
</select>
However, this doesn't seem to work. If however, I put the Motherboard enum into the Types Class, it does... Is there a way I'm missing to be able to nest enums in classes and use them in Thymeleaf?

# 答案1
**得分**: 1
解决方案：
为了进入嵌套类，你需要在它们之间加上 $ 符号。例如：
```java
${T(jre.maintainme.utils.strings.Types$PC$Motherboard)}
英文:
SOLUTION:
In order to go into nested classes, you need to add a $ between them. I.e:
${T(jre.maintainme.utils.strings.Types$PC$Motherboard)}

以下是翻译好的内容：
对我有效的是你尝试的第一件事情：
${T(com.my.package.path.Client.Type).values()
然而，IntelliJ声称无法解析Type，但IntelliJ是在撒谎！
英文:
What did work for me was the first thing you tried:
${T(com.my.package.path.Client.Type).values()
However, IntelliJ claims it can't resolve Type, but IntelliJ lies!
