我读了春季启动documentation，似乎如果我使用的是Thymeleaf，我可以将以下内容添加到我的application.properties文件中以实现缓存清除：
spring.resources.chain.strategy.content.enabled=true
spring.resources.chain.strategy.content.paths=/**
但它不起作用！
这是我看到的错误：
Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.boot.autoconfigure.web.ResourceProperties org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration$WebMvcAutoConfigurationAdapter.resourceProperties; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'spring.resources.CONFIGURATION_PROPERTIES': Could not bind properties to [unknown] (target=spring.resources, ignoreInvalidFields=false, ignoreUnknownFields=false, ignoreNestedProperties=false); nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'chain[strategy][fixed][version]' of bean class [org.springframework.boot.autoconfigure.web.ResourceProperties]: Cannot access indexed value in property referenced in indexed property path 'chain[strategy][fixed][version]'; nested exception is org.springframework.beans.NotReadablePropertyException: Invalid property 'chain[strategy][fixed][version]' of bean class [org.springframework.boot.autoconfigure.web.ResourceProperties]: Bean property 'chain[strategy][fixed][version]' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
我错过了什么？
答案 0 :(得分：4)
问题在于我使用的弹簧启动版本。 Spring引用1.2在1.3版本中没有任何此类属性。
