Spring SpEL-用于创建字符串和自定义对象映射的表达语言

Question

我正在使用Spring Boot示例从属性文件中读取以下内容。

sub.region.data={\
    AF: {'subRegionCd' : '34', 'subRegionName' : 'Southern Asia', 'subRegionDesc', '', 'status' : 'A'} \
}

我在下面使用过，但是没有用

@Value("#{${sub.region.data}}")
private Map<String, SubRegion> subRegionsMap; 

SubRegion.java

public class SubRegion {
    private String subRegionCd;
    private String subRegionName;
    private String subRegionDesc;
    private String subRegionStatus;
}

我遇到错误

Caused by: org.springframework.expression.spel.SpelParseException: Expression [{AF: {'subRegionCd' : '34', 'subRegionName' : 'Southern Asia', 'subRegionDesc', '', 'status' : 'A'} }] @78: EL1043E: Unexpected token. Expected 'colon(:)' but was 'comma(,)'

[您似乎在'subRegionDesc',之后犯了一个错误，我认为您的意思是使用冒号，而不是此处的逗号
