1. Configuration Annotation Proessor not found in classpath
. 使用 @ConfigurationProperties 报错 2. spring boot1.5 以上版本@ConfigurationProperties 取消 location 注解，只能使用 @PropertySource 3. 但使用 @PropertySource 依然出报错
官方解决方案，Maven 引入依赖

Caused by: java.lang.IllegalStateException: Ambiguous mapping.
Cannot map 'configurationController' method
com.xxx.springbootconfiguration.controller.configurationController#getUser()
to {GET }: There is already 'configurationController' bean method
com.xxx.springbootconfiguration.controller.configurationController#getInfo() mapped.

2.1 原因：
controller 层 @GetMapping 重复使用了两个相同的路径

| @GetMapping
public void getInfo() {
...
}
@GetMapping
public void getUser() {

}

两个 @GetMapping 都没有指定路径，才会有这样一条报错（已经被 getInfo map 了）

| to {GET }: There is already 'configurationController' bean method
com.xxx.springbootconfiguration.controller.configurationController#getInfo() mapped.

2.2 解决方法:
为 @GetMapping 添加值，保险一点两个都加，只加一个也可以
