SpringMVC Path Pattern /* & /**

参考

• spring-difference-of-and-with-regards-to-paths

两者区别

这种匹配方式来自于Apache ant:

• ? matches one character
• * matches zero or more characters
• ** matches zero or more 'directories' in a path

综上, 区别如下:

• /*
  最多能匹配到下一个/分隔符
• /**
  可以匹配多个目录

比如说有/path/to/action

• /*
  只能匹配到/path/
• /**
  可以匹配到/path/to/action

其他例子:

• com/t?st.jsp - matches com/test.jsp but also com/tast.jsp or com/txst.jsp
• com/*.jsp - matches all .jsp files in the com directory
• com/**/test.jsp - matches all test.jsp files underneath the com path
• org/springframework/**/*.jsp - matches all .jsp files underneath the org/springframework path
• org/**/servlet/bla.jsp - matches org/springframework/servlet/bla.jsp but also org/springframework/testing/servlet/bla.jsp and org/servlet/bla.jsp
