/** |

* Spring Boot 自定义异常处理 |
||||
* 所有的异常都派生自 Exception, 如果我们定义了某个异常的处理 Handler, Spring Boot 会调用用对应的异常 Handler, 否则会调用 Exception Handler. |
||||
* 有一个前提是在 application.yml 中定义两个属性, 让 springboot 在没有找到 url 的处理器触发异常; 让 springboot 不要自作多情加 /error 这个 map |
||||
* mvc: |
||||
* throw-exception-if-no-handler-found: true |
||||
* web: |
||||
* resources: |
||||
* add-mappings: false |
||||
* 只有如此, springboot 才会触发异常。 |
