java web开发中的奇葩事web.xml中context-param中的注释

2022-10-21 08:51:22

同事提交了代码。结果除同事之外，其他人全部编译报错。报错说web.xml中配置的一个bean 没有定义。按照报错提示，各种找，无果。

由于代码全部都是提交到svn主干，之前也没有做过备份，只能一步一步删除同事提交的代码，进行还原。

奇葩事情出现了！

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:/context_entry.xml
classpath:/context_web.xml

classpath:/GCSPcontext/context_policy_web.xml

</param-value>
</context-param>

引入文件没有错误，问题就在于这个注释上。突然想起之前也因为在这里写注释，报了一个错误，找了很久，但是为什么把错误指向另一个毫不相关为的文件呢。

附上web.xml文件配置
