Question

我有一个弹簧应用程序，我无法解决问题。当我使用PathVariable时，RequestMapping中的值会被添加到URI中，DispatchHandler会变得混乱。

例如，当我请求/Dashboard/project/1131/

时

我得到HTTP Status 404 - /Dashboard/project/1131/WEB-INF/jsp/projectDetail.jsp

项目/ 1131由于某种原因被添加到路径中

当我请求/Dashboard/projects Spring找到我的.jsp并呈现它。 / project/{projectId}不起作用 - 我得到上述行为。

这是我的控制器

@Controller
public class ProjectController {

protected final Log logger = LogFactory.getLog(getClass());

@RequestMapping(value = "projects", method=RequestMethod.GET)
public String projects() {
    return "/projects";
}

@RequestMapping(value="/project/{projectId}", method=RequestMethod.GET)
public String project(@PathVariable("projectId") String projectId, ModelMap map) {
    map.put("projectId", projectId);
    logger.info("Project Id: " + projectId);
    return "/projectDetail";
}

}

我的配置

的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">

<!-- Webapp name -->
<display-name>Dashboard</display-name>

<!-- default file name -->
<welcome-file-list>
    <welcome-file>home</welcome-file>
</welcome-file-list>

<!-- spring listener (all spring jars need to be in WEB-INF/lib -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- set servlet to DispatcherService -->
<servlet>
    <servlet-name>dashboard</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<!-- hand all requests to dispatcher service -->
<servlet-mapping>
    <servlet-name>dashboard</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

</web-app>

的AppConfig

@Configuration
public class AppConfig {

@Bean
ViewResolver viewResolver() {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("WEB-INF/jsp/");
    resolver.setSuffix(".jsp");
    return resolver;
}

}

仪表板servlet.xml中...

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

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc" 
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<!-- the packages to scan for annotations -->
<context:component-scan base-package="com.dennisstevens.dashboard.controller" />
<context:component-scan base-package="com.dennisstevens.dashboard" />
<context:component-scan base-package="com.dennisstevens.dashboard.domain" />

<!-- Tell Spring that MVC components are @Annotation Driven -->
<mvc:annotation-driven />

<!-- Tell Spring Dispatch Handler to look in WebContent/resources/ for resources -->
<mvc:resources mapping="/resources/**" location="/resources/" />

<!-- Tell Spring to scan for config annotations -->
<context:annotation-config/>

<!--  TODO: Figure out how to load this in AppConfig -->
<bean id="messageSource"
    class="org.springframework.context.support.ResourceBundleMessageSource">
    <property name="basename" value="messages" />
</bean>

</beans>

这必须很简单 - 但我查看了文档并在互联网上搜索了几个小时。从我能看到的情况来看，我看起来正在做的一切。

Answer 1

我认为resolver.setPrefix("/WEB-INF/jsp/");中有一个主要的斜杠应该为你解决。

使用PathVariable的Spring RequestMapping导致404
