spring - 无法以速度创建地图

Question

在我的速度模板中，我正在创建这样的地图：

#set($mymap.Map={"key":"value","key2":"value2"})

我认为它必须根据速度的文档工作，但是有下一个错误：

HTTP Status 500 - Could not load Velocity template for URL [editEmployee.vsl]; nested exception is org.apache.velocity.exception.ParseErrorException: Lexical error: org.apache.velocity.runtime.parser.TokenMgrError: Lexical error at line 44, column 36. Encountered: "{" (123), after : ""

type Exception report

这应该在 Velocity 中工作。我在 1.7 和 1.6.2 中都尝试了以下简单的代码段，它打印了正确的响应：

#set ($mymap = {})
#set ($mymap.Map={"key":"value","key2":"value2"})
$mymap

印刷：

{Map={key=value, key2=value2}}

因此，请确保错误确实在这里：

建议的错误位置（第 44 行，第 36 列）是否与您引用的行匹配？
如果您注释掉该行，错误是否仍然存在？
Spring 中的另一个组件是否对模板进行了预处理，以便最终 Velocity 看到的东西与您认为的不同？
- 如果您用更多的空格重新格式化代码，错误是否仍然存在？
如果您使用这种替代语法，错误是否仍然存在？

#set($discard = $mymap.put('Map', {'key':'value','key2':'value2'}))

尝试

#set($mymap={"key":"value","key2":"value2"})     
$mymap
