Spring 4.2调度程序servlet 404错误[重复]

Question

我使用 spring 4.2.2.RELEASE hibernate 5.0.2.Final 创建了一个应用程序，并成功地将这个应用程序部署到 jboss 为 7.1.1。我启用了日志级别 DEBUG，以便我可以看到正在发生的事情，并且根据日志，应用程序已成功部署。

war 文件的名称是 mycompany.war，因此它部署在上下文路径 /mycompany。

我有一个像下面这样的控制器类

@RestController
public class AbcController {
@RequestMapping(value = "/campaigns", method = RequestMethod.POST, produces = "application/json", consumes = "application/json")
    public Campaign addCampaign(@RequestBody Campaign campaign) throws ServiceException {
        return campaignService.addCampaign(campaign);
    }
}

现在，当我使用邮递员将请求发送到 localhost:8080/mycompany/campaigns 时，我收到以下调试日志的 404 错误

04:30:18,975 DEBUG [org.springframework.web.servlet.DispatcherServlet] (http--127.0.0.1-8080-1) DispatcherServlet with name 'dispatcher' processing POST request for [/mycompany/campaigns]
04:30:18,975 WARN  [org.springframework.web.servlet.PageNotFound] (http--127.0.0.1-8080-1) No mapping found for HTTP request with URI [/mycompany/campaigns] in DispatcherServlet with name 'dispatcher'
04:30:18,976 DEBUG [org.springframework.web.servlet.DispatcherServlet] (http--127.0.0.1-8080-1) Successfully completed request

下面是web.xml文件

<?xml version="1.0" encoding="UTF-8" ?>

    </servlet-mapping>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

下面是application-context.xml

<?xml version="1.0" encoding="UTF-8"?>

       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <context:annotation-config/>
    <tx:annotation-driven/>
    <context:component-scan base-package="com.mycompany"/>

    <bean id="myEmf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="persistenceXmlLocation" value="classpath*:META-INF/jpa-persistence.xml"/>
        <property name="persistenceUnitName" value="MainPU" />
    </bean>

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="myEmf"/>
    </bean>

    <bean id="persistenceExceptionTranslationPostProcessor" class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>
</beans>

为什么我会遇到这个问题？我检查了完整的日志，日志中没有异常没有错误。我还可以看到我的控制器正在由 spring 初始化。

Answer 1

您在应用程序上下文 XML 中错过了<mvc:annotation-driven/>。例如，需要允许使用注解进行请求映射。
