一、首先说一下打印的CONDITIONS EVALUATION REPORT这些信息是什么，有什么用

需要说明的一点，这些并不是报错，即使打印他们项目照样可以启动运行。他们只是一些打印出来的项目的一些日志信息。如果你能读懂，利用得好，还会对你有帮助。
之所以去掉他们，是因为这些日志信息大多情况下用不到，启动时打印出来看起来烦人。

二、日志出现的原因
因为项目中配置了日志的等级，也即是level属性。所以才会导致他们的出现。
三、去除打印
去除很简单了，只需要在项目的配置文件中添加下面一句配置即可：
yml文件：

logging.level.org.springframework.boot.autoconfigure: error

properties文件：

logging.level.org.springframework.boot.autoconfigure=ERROR

一般配置了这句话就没有了，但是我却碰见了特殊情况，我在我的配置文件中配置了以后，日志信息还是会打印，让人头疼。最终发现：
如果你使用了配置中心来管理配置文件的时候，那么这句话就不能放在你的配置文件中了，而应该放在bootstartp.properties中，才会起作用。

logging.level.org.springframework.boot.autoconfigure=ERROR
#注册中心地址
#发布的时候需要改为线上的注册中心地址
#spring.cloud.nacos.config.server-addr=77.1.24.51:8848
spring.cloud.nacos.config.server-addr=127.0.0.1:8848
#发布的时候需要改为线上的名称空间
#spring.cloud.nacos.config.namespace=cqzz-prod
spring.cloud.nacos.config.namespace=cqzz-dev
#配置组名子，需要在nacos的配置设置，不然找不到
spring.cloud.nacos.config.group=netsafe
#配置后缀，properties不需要
spring.cloud.nacos.config.file-extension=yml
#加载顺序是【n】:n越大 越先加载  如果配置相同，后面加载的会覆盖前面加载的
#不再默认的组，手动启动自动刷新
spring.cloud.nacos.config.ext-config[1].data-id=service-**-main.yml
spring.cloud.nacos.config.ext-config[1].group=netsafe
spring.cloud.nacos.config.ext-config[1].refresh=true
# 不再默认的组，手动启动自动刷新
spring.cloud.nacos.config.ext-config[0].data-id=service-**-mp.yml
spring.cloud.nacos.config.ext-config[0].group=netsafe
spring.cloud.nacos.config.ext-config[0].refresh=true

ps：我的配置中心使用的是nacos，所以我项目中添加了bootstarp.properties文件
