Spring之Interceptor之path patterns路径匹配规则

Spring之Interceptor之path patterns路径匹配规则


一、简单而言：

一个*：只匹配字符，不匹配路径（/）
两个**：匹配字符，和路径（/）


二、详细及更多：

public class AntPathMatcher
extends java.lang.Object
implements PathMatcher

PathMatcher implementation for Ant-style path patterns.

Part of this mapping code has been kindly borrowed from Apache Ant.

The mapping matches URLs using the following rules:

    ? matches one character
    * matches zero or more characters
    ** matches zero or more directories in a path
    {spring:[a-z]+} matches the regexp [a-z]+ as a path variable named "spring"

Examples

    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
    com/{filename:\\w+}.jsp will match com/test.jsp and assign the value test to the filename variable

Note: a pattern and a path must both be absolute or must both be relative in order for the two to match. Therefore it is recommended that users of this implementation to sanitize patterns in order to prefix them with "/" as it makes sense in the context in which they're used.



三、例子：

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {


/**

     - /**： 匹配所有路径
     - /admin/**：匹配 /admin/ 下的所有路径
     - /secure/*：只匹配 /secure/user，不匹配 /secure/user/info

 */


    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new LocaleInterceptor());
        
        registry.addInterceptor(new ThemeInterceptor())
                .addPathPatterns("/**")
                .excludePathPatterns("/admin/**");

        registry.addInterceptor(new SecurityInterceptor())
        .addPathPatterns("/secure/*", "/admin/**", "/profile/**");
    }
}
