今天在测试一个demo 时候发生如下错误：

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from file [D:\tmp\iLockApi\target\classes\com\ly\cache\CacheSupportProductServiceImp.class]; nested exception is com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: 2 字节的 UTF-8 序列的字节 2 无效。

Caused by: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: 2 字节的 UTF-8 序列的字节 2 无效。

说明如下：

1）当时执行下面的主函数

public static void main(String[] args) {
    ApplicationContext ctx = new ClassPathXmlApplicationContext("com/ly/cache/context-business-cache.xml");
    ProductService productService = ctx.getBean(ProductService.class);
    productService.queryById("1");
    productService.queryById("1");
}

2）项目是用maven构件的

3）spring配置文件和class放在一个包内，没有放到src/main/resources下

然后去网上搜了很久 都说文件编码原因，看了发现自己还是utf8，还有说是maven-resources-plugin 设置编码为utf8 改了没用。

最后我将spring配置文件改到 src/main/resources/context-business-cache.xml 解决问题
