在开发过程中Spring Mvc 默认 Url和参数名称都是区分大小写的

　　比如：www.a.com/user/getUserInfo?userId=1

　　　　　www.a.com/user/getuserInfo?userId=1

　　　　www.a.com/user/getUserInfo?userid=1

　　www.a.com/user/getuserinfo?userid=1

　　这些都认为不同的地址和参数，在实际中用户根本不区分这些，所以我们要忽略大小写

URL忽略大小写

import org.springframework.context.annotation.Configuration;import org.springframework.util.AntPathMatcher;import org.springframework.web.servlet.config.annotation.PathMatchConfigurer;import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;/** * Created by tianwei on 2017/6/22. */@Configurationpublic class SpringWebConfig extends WebMvcConfigurationSupport {    @Override    public void configurePathMatch(PathMatchConfigurer configurer) {        AntPathMatcher pathMatcher = new AntPathMatcher();        pathMatcher.setCaseSensitive(false);        configurer.setPathMatcher(pathMatcher);    }}

参数名称忽略大小写

import java.io.IOException;import java.util.Collections;import java.util.Enumeration;import java.util.Map;import javax.servlet.FilterChain;import javax.servlet.ServletException;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletRequestWrapper;import javax.servlet.http.HttpServletResponse;import org.springframework.util.LinkedCaseInsensitiveMap;import org.springframework.web.filter.OncePerRequestFilter;public class CaseInsensitiveRequestParameterNameFilter extends OncePerRequestFilter {    @Override    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)            throws ServletException, IOException {        filterChain.doFilter(new CaseInsensitiveParameterNameHttpServletRequest(request), response);    }    public static class CaseInsensitiveParameterNameHttpServletRequest extends HttpServletRequestWrapper {        private final LinkedCaseInsensitiveMap
     
       map = new LinkedCaseInsensitiveMap<>();        @SuppressWarnings("unchecked")        public CaseInsensitiveParameterNameHttpServletRequest(HttpServletRequest request) {            super(request);            map.putAll(request.getParameterMap());        }        @Override        public String getParameter(String name) {            String[] array = this.map.get(name);            if (array != null && array.length > 0)                return array[0];            return null;        }        @Override        public Map
      
        getParameterMap() {            return Collections.unmodifiableMap(this.map);        }        @Override        public Enumeration
       
         getParameterNames() {            return Collections.enumeration(this.map.keySet());        }        @Override        public String[] getParameterValues(String name) {            return this.map.get(name);        }    }}

定义Bean

web.xml 增加Filter


         
      
       caseInsensitiveRequestFilterProxy
          
      
       org.springframework.web.filter.DelegatingFilterProxy
        
       
         
      
       caseInsensitiveRequestFilterProxy
