问题：Could not resolve placeholder 'xxl.job.admin.addresses' in string value "${xxl.job.admin.addresse

spring整合中报错：Could not resolve placeholder 'xxl.job.admin.addresses' in string value "${xxl.job.admin.addresses}";

1.可能原因：properties文件加载不到

2.可能原因：properties字段对应不上（大小写，写错）

3.可能原因：转自：https://blog.youkuaiyun.com/longerandlonger/article/details/7193160 ，有可能是因为你配置了多个 org.springframework.beans.factory.config.PropertyPlaceholderConfigurer。
