无法建立速度

地图在我的Velocity模板，我创造这样的地图：无法建立速度

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

我认为，必须根据速度的文档工作，但有一个错误：

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 : ""

还有就是我的聚甲醛与速度：

为什么要同时使用速度的工具2.0和速度的工具，一般1.4吗？ –

我不知道哪些需要我包括这两个） – ema

这应该在速度工作。我尝试以下简单的片段，无论是在1.7和1.6.2，它打印正确的响应：

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

打印：

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

因此，请确保该错误确实是在这里：

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的另一个组件是否预先处理了模板，这样Velocity最终会看到另一件事，而不是你认为的那样？
- 如果用更多的空格重新格式化代码，错误仍然存在吗？
如果使用这种替代语法，错误仍然存在吗？

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

非常感谢答复Dumitriu！我发现我的错误。原因是速度的版本。我以为我包括1.7，但它是1.4。 – ema

尝试

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

您应该添加更多解释性答案。谢谢。 – Pau
