无法以速度创建地图

在我的力度模板中，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 : ""

我的pom有速度：

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

2 个答案:

答案 0 :(得分：2)

这应该适用于Velocity。我尝试了1.7和1.6.2中的以下简单片段，并打印出正确的响应：

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

打印：

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

所以，确保错误确实在这里：

  1. 建议的错误位置（第44行，第36列）是否与您引用的行匹配？
  2. 如果您注释掉该行，错误是否仍然存在？
  3. Spring的另一个组件是否预先处理模板，以便最终Velocity看到的东西比你想象的还要多？
    • 如果用一些更多的空格重新格式化代码，错误是否仍然存在？
  4. 如果使用此备用语法，错误是否仍然存在？
    5. #set($discard = $mymap.put('Map', {'key':'value','key2':'value2'}))

答案 1 :(得分：0)

试

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