2、错误原因
maps不是一个序列，不能用list遍历map
<#--freemarker HashMap取值-->
<#assign maps={"1":"张三丰","2":"李思思","3":"张三强","4":"王五"}>
${maps["3"]}
<#list maps as map>
${map}
</#list>
3、解决办法
先获取map中的key值，再通过key值序列遍历map
<#--freemarker HashMap取值-->
<#assign maps={"1":"张三丰","2":"李思思","3":"张三强","4":"王五"}>
${maps["3"]}
<#assign keys=maps?keys>
<#list keys as key>
${key}----${maps[key]}
</#list>
