java哪个版本的Velocity模板将支持地图创建

Question

我正在velocity模板版本1.2中发送映射并访问，但我尝试在vm中创建映射，但无法创建，并出现异常。请给你指导

#set($buyerActionStat = {
                            "0":"New",
                            "5":"Response-Acknowledged",
                            "6":"Response-Accepted",
                            "7":"Response-Rejected"                         
                        })

例外情况：

org.apache.velocity.exception.ParseErrorException: Lexical error: org.apache.velocity.runtime.parser.TokenMgrError: Lexical error at line 5, column 25.  Encountered: "{" (123), after : ""

该表达式仅由velocity版本引起

使用apache velocity版本1.6.2或更高版本

Maven依赖

<dependency>
                <groupId>org.apache.velocity</groupId>
                <artifactId>velocity</artifactId>
                <version>1.6.2</version>
            </dependency>
