Question

我正在使用<mvc:annotation-driven/>，我想配置RequestMappingHandlerMapping来禁用useTrailingSlashMatch。当我声明另一个RequestMappingHandlerMapping时，我将结束2 RequestMappingHandlerMapping。如何配置RequestMappingHandlerMapping？

Answer 1

正如您已经注意到的，通过删除mvc:annotation-driven并替换整个xml等效项，这在xml中是可行的：

<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>
        </bean>
    </property>
    <property name="messageConverters">
        <list>
            <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/>
            <bean class="org.springframework.http.converter.xml.Jaxb2RootElementHttpMessageConverter"/>
            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/>
            <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="handlerMapping" class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
    <property name="useTrailingSlashMatch" value="true"></property>
</bean>

Answer 2

您可以尝试使用Java配置来覆盖RequestMappingHandlerMapping值

@Configuration
@ComponentScan(basePackages = "base.package.name")
public class WebAppConfig extends WebMvcConfigurationSupport {

    @Override
    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping rmh = super.requestMappingHandlerMapping();
        rmh.setUseTrailingSlashMatch(false);
        return rmh;
    }
}

如果您想要一个不涉及在Spring中复制功能的解决方案，那么您可以覆盖DisplatcherServlet。在Servlet 3.0容器中，这可能看起来像：

@WebServlet(name="spring-dispatcher", loadOnStartup=1, urlPatterns={"/"},
        initParams={
            @WebInitParam(name="contextConfigLocation", 
            value="/WEB-INF/spring/spring-dispatcher-servlet.xml")})
public class MyDispatcherServlet extends DispatcherServlet {

    @Override
    protected void initStrategies(ApplicationContext context) {
        super.initStrategies(context);
        for (RequestMappingInfoHandlerMapping handlerMapping 
                : BeanFactoryUtils.beansOfTypeIncludingAncestors(
                    context, RequestMappingInfoHandlerMapping.class, true, false).values()) {

            handlerMapping.setUseTrailingSlashMatch(false);
        }
    }
}

Answer 4

将以下内容添加到弹簧配置文件中以切换useTrailingSlashMatch字段。

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
    <property name="useTrailingSlashMatch" value="true">
    </property>
</bean>
