java.nio.charset.MalformedInputException: Input length = 1异常 java.nio.charset.MalformedInputException: Input length = 1 错误 1.其中一个最容易找的原因是interface 和 xml的 namespace 对应不上还有一种情况是application.yml的编码问题，会导致去是添加resouce的配置（如下）时出现java.nio.charset.MalformedInputException: Input length = 1，mybatis也绑定不上。此时应该做的的是将所有的编码都转为utf-8。此处idea为例 File --> Settings --> Editor —>File Encodings ，将所有的格式都转成utf-8格式来源： CSDN 作者：我是暗器啊链接： https://blog.csdn.net/WoshiAnQia/article/details/84144814

css---8 过渡属性刨析

阅读更多关于 css---8 过渡属性刨析

1. transition-property 默认值为 all，表示所有可被动画的属性都表现出过渡动可以指定多个 property 属性值： none 没有过渡动画。 all 所有可被动画的属性都表现出过渡动画。 IDENT 属性名称（可以指定多个） transition-property: width,height; transition-duration: 9s,1s; 2 transition-duration 属性以秒或毫秒为单位指定过渡动画所需的时间。默认值为 0s ，表示不出现过渡动画。可以指定多个时长，每个时长会被应用到由 transition-property 指定的对应属性上。如果指定的时长个数小于属性个数，那么时长列表会重复。如果时长列表更长，那么该列表会被裁减。两种情况下，属性列表都保持不变。属性值以毫秒或秒为单位的数值 <time> 类型。表示过渡属性从旧的值转变到新的值所需要的时间。如果时长是 0s ，表示不会呈现过渡动画，属性会瞬间完成转变。不接受负值。一定要加单位(不能写0 一定要写0s 1s,0s,1s)！ transition-property:width,background; <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title

The resulting HTML files do not specify an encoding and do not use HTML entities, so the umlauts aren't displayed correctly in any browser. What can I do to change this? 回答1: See the -charset , -encoding and -docencoding flags for the javadoc command . -encoding specifies the input encoding -docencoding specifies the output encoding -charset makes javadoc include a meta tag with encoding info 回答2: Modified from Eclipse javadoc
