Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/context]html
原本比較習慣直接用eclipse裏面的export成可運行jar包,開始選擇的library handling 是第一個選項,結果運行後一直報下面的錯誤;java
java -jar testmq.jar

查詢了好多一樣的問題,覺得是直接export不太對,須要用maven打包,好比看到了下面這個連接https://www.cnblogs.com/icewee/articles/3703491.html,是由於缺什麼包致使;mvc
而後換成了mavn打包,結果仍是不太對,和我用export導出來的效果同樣,查了好久都沒有查到緣由;eclipse
剛開始,用mvn打包,直接都是打成文件的 maven
https://www.cnblogs.com/dzblog/p/6913809.htmlspa
按這個方式去打包,結果都生成了別的lib包,沒有直接打進jar包;因此只能在當前目錄下運行;.net
而後看到了這篇文章 https://blog.csdn.net/birdben/article/details/51951651插件
明白了緣由,是由於由於的plugin不對;
主要使用了maven-jar-plugin和maven-dependency-plugin這兩個Maven的插件,maven-jar-plugin負責構建jar包,maven-dependency-plugin負責導出全部依賴的jar包,這裏咱們使用了maven-assembly-plugin插件,這個插件能夠將全部當前jar依賴的全部jar包打包到當前jar裏面,這樣就不須要導出全部依賴的jar包了,直接運行jar就能夠了,實在太方便了 ^_^
可是這樣仍是不行,感受和export的效果實際上是一致的;因而又找了一些文章
https://blog.csdn.net/qing0706/article/details/51612040
,總算找到了緣由;結果也是確實是由於
spring.handlers、spring.schemas,打開這兩個文件一看,裏面都只包含了spring-mvc的配置
須要在pom的打包後面添加別的插件,
再一想,我用maven和eclipse打包效果同樣,是否是eclipse自己就有這樣的方法了,
因而,嘗試了一下,過然如此;
