edit config tin tco pbo jmx dev start default

今天在做一個dubbo服務端的時候，啟動成功，dubbo也註冊成功，但是啟動日誌中就出現[java:comp/env/spring.liveBeansView.mbeanDomain] not found這個日誌，網上搜搜，果然很多人出現過這個問題。

[plain] view plain copy

錯誤原因：就是spring-context.jar包中提供通過JMX來實時查看spring放在applicationContext裏的bean列表功能，會在項目配置文件裏找一個叫"spring.liveBeansView.mbeanDomain"的環境變量,沒找到,就報錯了。

j解決辦法就是在項目中的web.xml中添加如下配置：

1. <context-param>
2. <param-name>spring.profiles.active</param-name>
3. <param-value>dev</param-value>

5. <context-param>
6. <param-name>spring.profiles.default</param-name>
7. <param-value>dev</param-value>
