1.2、错误原因
"没有任何值存在"前多了一个空格
1 ${(student.course.courseName)！"没有任何值存在"}
1.3、解决办法
"没有任何值存在"前面的空格去掉
1 ${(student.course.courseName)!"没有任何值存在"}

2.2，错误原因
结束标签书写不对
1 <#assign stu={"name":"zhangsan","age":"21","sex":"man"}> 2 <#assign keys = stu?keys> 3 <#list keys as key> 4 ${key} = ${stu[key]}; 5 <#list>
2.3，解决办法
正确写结束标签
1 <#assign stu={"name":"zhangsan","age":"21","sex":"man"}> 2 <#assign keys = stu?keys> 3 <#list keys as key> 4 ${key} = ${stu[key]}; 5
就是不是<#list>而是

3.2，错误原因
1 <#--freemarker自定义标签--> 2 <#macro write> 3 ${repeat("张三丰",3)} 4 <#macro>
3.3、解决办法
又犯了同样的错误，结束标签没有封口
1 <#--freemarker自定义标签--> 2 <#macro write> 3 ${repeat("张三丰",3)} 4
