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）

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:

 

< 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）

 

< 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）

 

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