SpringMvc_@RequestMapping设置Router Url大小写不敏感

http://stackoverflow.com/questions/4150039/how-can-i-have-case-insensitive-urls-in-spring-mvc-with-annotated-mappings

 

以下四个Url可以指向同一个Controller方法

http://localhost:8080/login/userLOgin
http://localhost:8080/LogiN/userLOgin
http://localhost:8080/login/userlogin
http://localhost:8080/Login/UserLogin

一、解决方案One(下面的applicationContext.xml配置有些可以简化）

1 2 3 4 5 6 7

public class CaseInsenseticePathMatcher extends AntPathMatcher {     @Override     protected boolean doMatch(String pattern, String path, boolean fullMatch, Map<String, String> uriTemplateVariables) {         System.err.println(pattern + " -- " + path);         return super.doMatch(pattern.toLowerCase(), path.toLowerCase(), fullMatch, uriTemplateVariables);     } }

applicationContext.xml:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

<bean id="matcher" class="test.CaseInsenseticePathMatcher"/>   <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">     <property name="pathMatcher" ref="matcher"/> </bean>   <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">     <property name="pathMatcher" ref="matcher"/>     <property name="webBindingInitializer">         <bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer"/>     </property>     <property name="messageConverters">         <list>             <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/>             <bean class="org.springframework.http.converter.StringHttpMessageConverter"/>             <bean class="org.springframework.http.converter.FormHttpMessageConverter"/>             <bean class="org.springframework.http.converter.xml.SourceHttpMessageConverter"/>         </list>     </property> </bean>   <bean id="conversion-service" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"/>

简化后的applicationContext.xml: 必须配置HandlerMapping、HandlerAdapter（即Controller和Action）

1 2 3 4 5 6 7 8 9 10 11

<bean id="matcher" class="com.le.lej.common.CaseInsenseticePathMatcher" />       <bean         class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">         <property name="pathMatcher" ref="matcher" />     </bean>       <bean         class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">         <property name="pathMatcher" ref="matcher" />     </bean>

 

 

    

二、解决方案Two(需要Spring4.2以上支持）

1 2 3 4 5 6 7 8 9

@Configuration public class WebConfig extends WebMvcConfigurerAdapter {     @Override     public void configurePathMatch(PathMatchConfigurer configurer) {         AntPathMatcher matcher = new AntPathMatcher();         matcher.setCaseSensitive(false);         configurer.setPathMatcher(matcher);     } }
