原因：org.springframework.expression.spel.SpelParseException：表达式[] @ 31：EL1043E：意外的令牌。应为'colon（:)'，但为'rcurly（}）>

Question

我在发布问题之前通过了How to pass a Map<String, String> with application.properties之类的链接，但这不符合我的要求。

application.properties

soap.all.endpoints={getEmployeeRoles: ['ABC', 'EFG'], getStudentRoles: ['PQR', 'XYZ']} 
我正在使用下面的代码阅读，但给我错误。

@Value("#{${soap.all.endpoints}}")
private Map<String, List<String>> roles;
错误：

Caused by: org.springframework.beans.factory.BeanExpressionException: Expression parsing failed; nested exception is org.springframework.expression.spel.SpelParseException: Expression [{getEmployeeRoles: 'ABC', 'EFG'}] @31: EL1043E: Unexpected token. Expected 'colon(:)' but was 'rcurly(})'

我通过了类似的链接：如何在发布问题之前通过application.properties通过Map ，但这不能满足我的要求。 application.properties soap.all ....

我能够使用]解决>

您可以使用类似于SPEL json的语法在属性文件中编写一个简单的映射或列表的映射。
