容器启动的时候出错
配置文件如下:
报错信息如下:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'communityController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private int cn.wanjubang.toy.core.controller.Basecontroller.maxPic; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'int'; nested exception is java.lang.NumberFormatException: For input string: "${maxPic}"
Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private int cn.wanjubang.toy.core.controller.Basecontroller.maxPic; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'int'; nested exception is java.lang.NumberFormatException: For input string: "${maxPic}"
怎么解决呢?

1.这个首先确保下,你的properties位置没有错,如果你是跑单测时候,最好确保在test的路径下也有。
2.如果确认配置文件是OK的,spring会有一个工具类NumberUtils
来处理。NumberUtils
来处理。
return (T) (isHexNumber(trimmed) ? Byte.decode(trimmed) : Byte.valueOf(trimmed));
}
else if (targetClass.equals(Short.class)) {
return (T) (isHexNumber(trimmed) ? Short.decode(trimmed) : Short.valueOf(trimmed));
}
else if (targetClass.equals(Integer.class)) {
return (T) (isHexNumber(trimmed) ? Integer.decode(trimmed) : Integer.valueOf(trimmed));
}
会把string转换成Intger类型,如果还是不行的话,可以试试用SPEL
"#{T(java.lang.Integer).parseInt('${maxPic}')}"
会把string转换成Intger类型,如果还是不行的话,可以试试用SPEL
语句,来强制转换🎜

Failed to convert value of type 'java.lang.String' to required type 'int'; nested exception is java.lang.NumberFormatException: For input string: "${maxPic}"
这个报错这么明显。。。init bean的时候spring自动转换赋值macPic参数,但是String 转int 异常了

exception is java.lang.NumberFormatException: For input string: "${maxPic}",你是不是写的maxPic加了引号报错了
