#类型转换异常 #web.xml配置 #过滤器配置 #字符编码

博客指出在web.xml使用字符编码过滤器时，因参数值配置不当，将布尔类型的forceRequestEncoding和forceResponseEncoding写成了utf - 8，导致org.springframework.beans.TypeMismatchException类型转换异常，并说明了若forceRequestEncoding为true会设置请求编码等情况。

主要异常信息

org.springframework.beans.TypeMismatchException: Failed to convert property value of type ‘java.lang.String’ to required type ‘boolean’ for property ‘forceResponseEncoding’; nested exception is java.lang.IllegalArgumentException: Invalid boolean value [utf-8]

问题

在web.xml使用字符编码过滤器中，参数值配置不当。
在这里插入图片描述
进入到CharacterEncodingFilter类中发现：forceRequestEncoding和forceResponseEncoding是布尔值，我写成了utf-8，所以就造成了类型转换异常
在这里插入图片描述
如果forceRequestEncoding为true就设置请求编码，如果forceRequestEncoding为true就设置响应编码
在这里插入图片描述

解决

在这里插入图片描述

希望能帮到你！！
