Springcloud從Nacos的yml文件讀取出錯 · Java學習筆記

## 問題錯誤提示先把yml內容打印了, 然后提示這個錯誤 ``` org.yaml.snakeyaml.error.YAMLException: java.nio.charset.MalformedInputException: Input length = 1 ``` 或者報錯如下 ``` - Application run failed java.lang.ArrayIndexOutOfBoundsException: -1 at org.yaml.snakeyaml.reader.StreamReader.peek(StreamReader.java:136) at org.yaml.snakeyaml.scanner.ScannerImpl.scanToNextToken(ScannerImpl.java:1222) at org.yaml.snakeyaml.scanner.ScannerImpl.fetchMoreTokens(ScannerImpl.java:308) at org.yaml.snakeyaml.scanner.ScannerImpl.checkToken(ScannerImpl.java:248) at org.yaml.snakeyaml.parser.ParserImpl$ParseBlockMappingKey.produce(ParserImpl.java:634) at org.yaml.snakeyaml.parser.ParserImpl.peekEvent(ParserImpl.java:165) at org.yaml.snakeyaml.comments.CommentEventsCollector$1.peek(CommentEventsCollector.java:59) at org.yaml.snakeyaml.comments.CommentEventsCollector$1.peek(CommentEventsCollector.java:45) at org.yaml.snakeyaml.comments.CommentEventsCollector.collectEvents(CommentEventsCollector.java:140) at org.yaml.snakeyaml.comments.CommentEventsCollector.collectEvents(CommentEventsCollector.java:119) at org.yaml.snakeyaml.composer.Composer.composeScalarNode(Composer.java:214) at org.yaml.snakeyaml.composer.Composer.composeNode(Composer.java:184) at org.yaml.snakeyaml.composer.Composer.composeValueNode(Composer.java:314) at org.yaml.snakeyaml.composer.Composer.composeMappingChildren(Composer.java:305) at org.yaml.snakeyaml.composer.Composer.composeMappingNode(Composer.java:286) at org.yaml.snakeyaml.composer.Composer.composeNode(Composer.java:188) at org.yaml.snakeyaml.composer.Composer.composeValueNode(Composer.java:314) at org.yaml.snakeyaml.composer.Composer.composeMappingChildren(Composer.java:305) at org.yaml.snakeyaml.composer.Composer.composeMappingNode(Composer.java:286) at org.yaml.snakeyaml.composer.Composer.composeNode(Composer.java:188) ``` 1. 正在使用的項目, 更新代碼之后出現這個錯誤, 運行失敗, 打包成功代碼正常, 是yml編碼問題, 首先idea確認file ->settings ->file encodings 里的都是utf-8編碼, 是gbk就改成utf-8 啟動還是報錯則: 把yml 執行編碼轉換再不行就yml文件中隨便改動, 如:回車換行, 加點改動, 再保存測試(這個方式要多試幾次, 我這邊是每個頁面改了多處地方, 修改多次才行的) 再不行打開yml文件, 點擊idea右下角的utf-8, 選擇gbk, 點擊convert, 點擊右下角gbk, 選擇utf-8, 點擊convert 把所有的yml都這樣轉換一遍, 這邊就運行成功了 ![](https://img.kancloud.cn/00/75/00750f499dc84366e3abc5110a50f7cb_657x289.png) ![](https://img.kancloud.cn/5f/7b/5f7b4a750255500e13e3e2953ffc5e63_605x179.png) 2. 經測試, 我這邊是因為做測試的時候, 復制了一份數據庫, 數據庫名稱再原來的基礎上加了數字1, 結果就是因為這個啟動時 yml 報錯了就是讀取Nacos的yml出錯了, 解決方式根據情況的不同, 可能某一種才生效 ## 解決方式1(不推薦) yml里的中文全部刪除, ## 解決方式2 項目里 file -settings 搜索 encodings, 找到 File encodings, 把里面的gbk全部換成utf- 這樣設置的只有本項目生效, 去這里再設置就是新項目也生效(idea2020.3) ![](https://img.kancloud.cn/27/3f/273f0762bfe2876f699c560ec623b107_558x382.png) ## 解決方式3 這種比較奇葩, 改了編碼沒有用, Nacos yml里有中文的情況下, 隨便改了改, 有時就好了
