resourcePatternResolver.getResources() 报错 *.xml cannot be opened beacuse is does not exist

这个问题其实是粗心引起的。
在配置数据源的时候，黏贴下代码

@Bean(name = "mysqlSqlSessionFactory")
    public SqlSessionFactory mysqlSqlSessionFactoryBean()throws Exception {
	        SqlSessionFactoryBean factory=new SqlSessionFactoryBean();
	        factory.setDataSource(mysqlDataSource());
	        factory.setTypeAliasesPackage("com.example.clickhousedemo.entity.mysql");
	        ResourcePatternResolver resourcePatternResolver=new PathMatchingResourcePatternResolver();
	        factory.setMapperLocations(resourcePatternResolver.getResources("classpath:mapper/mysql/*.xml"));
	        factory.getObject().getConfiguration().setMapUnderscoreToCamelCase(true);
	        return factory.getObject();
    }

factory.setMapperLocations(resourcePatternResolver.getResources(“classpath:mapper/mysql/*.xml”));
这一行注意是resourcePatternResolver.getResources()，tab直接快了，写成了getResource() 少了个s导致了xml找不到。

致那些粗心的同学！！！
