如何比较Spock中集合中不同类型对象的相似字段名？

import java.lang.reflect.Field

class ObjectComparator {
    static List<String> getSimilarFields(Object obj1, Object obj2) {
        List<String> similarFields = []
        
        // 获取obj1的字段列表
        Field[] fields1 = obj1.getClass().declaredFields
        
        // 遍历obj1的字段列表
        for (Field field1 in fields1) {
            String fieldName1 = field1.name
            Class fieldType1 = field1.type
            
            // 获取obj2的字段列表
            Field[] fields2 = obj2.getClass().declaredFields
            
            // 遍历obj2的字段列表
            for (Field field2 in fields2) {
                String fieldName2 = field2.name
                Class fieldType2 = field2.type
                
                // 比较字段名称和类型
                if (fieldName1 == fieldName2 && fieldType1 == fieldType2) {
                    similarFields.add(fieldName1)
                }
            }
        }
        
        return similarFields
    }
}

// 示例用法
class Person {
    String name
    int age
}

class Employee {
    String name
    int salary
}

def person = new Person(name: "John", age: 30)
def employee = new Employee(name: "Jane", salary: 5000)

def similarFields = ObjectComparator.getSimilarFields(person, employee)
println(similarFields)
