如何使用groovy脚本引擎替换ternaryoperation中的变量

def variable = 10
def result = variable > 5 ? "大于5" : "小于等于5"
println(result)

<dependency>
    <groupId>org.codehaus.groovy</groupId>
    <artifactId>groovy-all</artifactId>
    <version>3.0.9</version>
</dependency>

import groovy.lang.Binding;
import groovy.lang.GroovyShell;

Binding binding = new Binding();
GroovyShell shell = new GroovyShell(binding);

String script = "def variable = ${variable}; variable > 5 ? '大于5' : '小于等于5'";
binding.setVariable("variable", variable);

Object result = shell.evaluate(script);
System.out.println(result);
