springboot之Filter的URI匹配规则

@Slf4j
public class AntPathMatcherTests {
    @Test
    public void matcher(){
        AntPathMatcher antPathMatcher = new AntPathMatcher();
        log.info("/a是否匹配/a/*：{}",antPathMatcher.match("/a/*","/a"));//false
        log.info("/a/b是否匹配/a/*：{}",antPathMatcher.match("/a/*","/a/b"));//true
        log.info("/a是否匹配/a/bc/def：{}",antPathMatcher.match("/a/bc/def","/a"));//false
        log.info("/a/b/c是否匹配/a/*/def：{}",antPathMatcher.match("/a/*/def","/a/b/c"));//false
        log.info("/a/b/def是否匹配/a/*/def：{}",antPathMatcher.match("/a/*/def","/a/b/def"));//true
    }
}

当我们想对某些uri过滤时就可以这样做
yml配置过滤的uri或者url

ignore:
  uri:
  - /api/test
  - /api/demo
  - /api/*/test
  - /api/demo/*

写一个过滤uri的配置类

@Data
@Configuration
@ConfigurationProperties(prefix = "ignore") // 配置文件的前缀
public class UriConfig {
    private List<String> uri;//等价于@Value("{ignore.uri}")，但是@Value多个要用切割的方式，这种方式直接拿就好。建议多个值需要切割时使用这种写法
}

使用过滤的uri的方法引入，如：filter过滤器

@Component
@WebFilter(urlPatterns = "/*", filterName = "DemoFilter")
public class DemoFilter implements Filter{

	@Resource
	private UriConfig uriConfig;
	
	public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain){
		HttpServletRequest request = (HttpServletRequest) servletRequest;
        HttpServletResponse response = (HttpServletResponse) servletResponse;
        
		String requestURI = request.getRequestURI();//请求地址
		AntPathMatcher antPathMatcher = new AntPathMatcher();
		boolean passUri = uris.stream().anyMatch(uri -> antPathMatcher.match(uri,requestURI));
		log.info(requestURI + "是否是滤地址：{}" , passUri);
		filterChain.doFilter(request, response);
	}
}
