启动异常

APPLICATION FAILED TO START

Description:
Failed to configure a DataSource: no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
配置：
spring.datasource.url = jdbc:mysql\://192.168.0.20\:1504/f_me?setUnicode=true&characterEncoding=utf8
spring.datasource.username = ...
spring.datasource.password = ...
问题分析:
在spring xml配置文件中引用了数据库地址 所以需要对:等进行转义处理
springboot如果没有指定spring.datasource.driver-class-name 会根据spring.datasource.url解析自动匹配驱动类, 而springboot不是xml方式配置的 所以spring.datasource.url不需要进行转义 ，加了转义之后对驱动解析就有问题了, 总之问题出在spring.datasource.url上，格式不正确spring自动解析不了（我这里是冒号前多了"\"转义符号）
解决问题:
修改配置
spring.datasource.url = jdbc:mysql://192.168.0.20:1504/f_me?setUnicode=true&characterEncoding=utf8
spring.datasource.username = ...
spring.datasource.password = ...
（注意其它spring.datasource.url格式错误问题也可能会导致同样的问题)
