ImmutableMap 的一些使用：https://www.baeldung.com/java-immutable-maps
package com.awj.mall.restfulapi.config;import java.util.HashMap;
import java.util.Map;import com.google.common.collect.ImmutableMap;public class Test {public static void main(String[] args) {Map<String, Object> map = ImmutableMap.<String,Object>builder().put("name", "1111").put("age", 28).build();System.out.print(map);Map<String, Object> map1=new HashMap<String,Object>(){{put("name", "1111");put("age", 28);}};System.out.print(map1);}}
