题

我将传递到速度模板逗号分隔值，而在开始时，我会收到parseerrorexception。如何修复？

#set ($test=StringUtils.split($filterFieldCSV,","))

    #foreach ( $filterField in $test )
    <!-- process something here -->
#end



Caused by: org.apache.velocity.exception.ParseErrorException: Encountered "StringUtils" at t-50[line 3, column 12] Was expecting one of:
    "[" ...
    "{" ...
    "(" ...
    <WHITESPACE> ...
    <STRING_LITERAL> ...
    "true" ...
    "false" ...
    <INTEGER_LITERAL> ...
    <FLOATING_POINT_LITERAL> ...
    <IDENTIFIER> ...
    "{" ...
    <LOGICAL_NOT> ...

有帮助吗？

解决方案

我只需要有以下陈述：

#set($test=$filterFieldCSV.split(","))

代替：

#set($test=StringUtils.split($filterFieldCSV,","))
