Spring MVC @RequestMapping注释的不区分大小写映射

Question

可能重复:
如何在带有注释映射的Spring MVC中使用不区分大小写的URL

我有控制器在其中有多个@RequestMapping注释.

@Controller
public class SignUpController {

 @RequestMapping("signup")
 public String showSignUp() throws Exception {
    return "somejsp";
 }

 @RequestMapping("fullSignup")
 public String showFullSignUp() throws Exception {
    return "anotherjsp";
 }

 @RequestMapping("signup/createAccount")
 public String createAccount() throws Exception {
    return "anyjsp";
 }
}

如何将这些@RequestMapping映射到不区分大小写.即如果我使用"/ fullsignup"或"/ fullSignup",我应该得到"anotherjsp".但现在这种情况并没有发生.只有"/ fullSignup"才能正常工作.

我试过扩展RequestMappingHandlerMapping但没有成功.我也尝试过AntPathMatcher,就像在这个论坛上提到的另一个问题,但它也不适用于@RequestMapping注释.

调试控制台

服务器启动时的输出控制台.

我添加了两张显示问题的图片.我已经尝试了下面提到的两种解决方案.控制台说它映射了小写的URL,但是当我请求访问带有小写url的方法时,它会显示存储值的原始映射包含MixCase URLS.

我在Spring MVC中如何使用带注释映射的不区分大小写的URL的方法之一可以完美地工作.我只是在控制器和请求方法的水平上使用@RequestMapping的组合尝试它并且它干净利落,我只是在这里为Spring 3.1.2复制它:

CaseInsensitivePathMatcher:

import java.util.Map;

import org.springframework.util.AntPathMatcher;

public class CaseInsensitivePathMatcher extends AntPathMatcher {
    @Override
    protected boolean doMatch(String pattern, String path, boolean fullMatch, Map<String, String> uriTemplateVariables) {
        return super.doMatch(pattern.toLowerCase(), path.toLowerCase(), fullMatch, uriTemplateVariables);
    }
}

使用Spring MVC注册此路径匹配器,删除<mvc:annotation-driven/>注释,并替换为以下内容,进行适当配置:

<bean name="handlerAdapter" class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
    <property name="webBindingInitializer">
        <bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer">
            <property name="conversionService" ref="conversionService"></property>
            <property name="validator">
                <bean class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
                    <property name="providerClass" value="org.hibernate.validator.HibernateValidator"></property>
                </bean>
            </property>
        </bean>
    </property>
    <property name="messageConverters">
        <list>
            <ref bean="byteArrayConverter"/>
            <ref bean="jaxbConverter"/>
            <ref bean="jsonConverter"/>
            <bean class="org.springframework.http.converter.StringHttpMessageConverter"></bean>
            <bean class="org.springframework.http.converter.ResourceHttpMessageConverter"></bean>
            <bean class="org.springframework.http.converter.xml.SourceHttpMessageConverter"></bean>
            <bean class="org.springframework.http.converter.xml.XmlAwareFormHttpMessageConverter"></bean>
        </list>
    </property>
</bean>
<bean name="byteArrayConverter" class="org.springframework.http.converter.ByteArrayHttpMessageConverter"></bean>
<bean name="jaxbConverter" class="org.springframework.http.converter.xml.Jaxb2RootElementHttpMessageConverter"></bean>
<bean name="jsonConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"></bean>
<bean name="caseInsensitivePathMatcher" class="org.bk.lmt.web.spring.CaseInsensitivePathMatcher"/>
<bean name="handlerMapping" class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
    <property name="pathMatcher" ref="caseInsensitivePathMatcher"></property>
</bean>

或者使用@Configuration更轻松,更干净:

@Configuration
@ComponentScan(basePackages="org.bk.webtestuuid")
public class WebConfiguration extends WebMvcConfigurationSupport{

    @Bean
    public PathMatcher pathMatcher(){
        return new CaseInsensitivePathMatcher();
    }
    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping handlerMapping = new RequestMappingHandlerMapping();
        handlerMapping.setOrder(0);
        handlerMapping.setInterceptors(getInterceptors());
        handlerMapping.setPathMatcher(pathMatcher());
        return handlerMapping;
    }
}
