maven管理spring,运行项目时出现spring-beans.xsd文档找不到异常

报错

不联互联网网启动服务,报错如下:

org.xml.sax.SAXParseException; lineNumber: 13; columnNumber: 69; schema_reference.4: 无法读取方案文档 'https://www.springframework.org/schema/context/spring-beans.xsd', 原因为 1) 无法找到文档; 2) 无法读取文档; 3) 文档的根元素不是 <xsd:schema>。

xml约束如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

错误原因:

需要联网下载 https://www.springframework.org/schema/context/spring-beans.xsd 文件,当不能联网,或者网络特别慢时,就会报错

如果网络正常,会先下载该文件,由于该文件在国外服务器上,所以下载缓慢,导致启动服务慢

解决方法

其实该文件已经存在在本地jar包中,让spring到本地中找即可

将上面的 https 改成 http,就不在联网下载文件,而是到本地中找

完整约束

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">
