Spring MVC 映射-未找到 404 错误-使用 Gradle 和 Jetty

Question

不知道我在这里错过了什么......

sample Controller :

@Controller
@RequestMapping(value="/schedule/*")
public class ScheduleController {

   @RequestMapping(value="/job", method=RequestMethod.GET)
   @ResponseBody
    public String test(@RequestParam (value = "name", required = false) String name) throws Exception{

    System.out.println("name:" + name);
    return "Yes, I got it, " + name;
   }
}

web.xml

    <display-name>JS</display-name>

<!-- Spring MVC -->
<servlet>
    <servlet-name>controller</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:/WEB-INF/spring/js-rest.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>controller</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

js-rest.xml 文件

<context:component-scan base-package="com.test.js.controller">    </context:component-scan>
<context:annotation-config />

毕业典礼:

apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'jetty' 
apply plugin: 'eclipse-wtp'

sourceCompatibility = 1.5
version = '1.0'
jar {
  manifest {
    attributes 'Implementation-Title': 'Gradle Quickstart',
               'Implementation-Version': version
  }
}

repositories {
  mavenCentral()
}

dependencies {
   compile group: 'commons-collections', name: 'commons-collections', version: '3.2'
   testCompile group: 'junit', name: 'junit', version: '4.+'

   providedCompile 'javax.servlet:servlet-api:2.5'

}

jettyRunWar.contextPath = ''

Controller 在 src\main\java\com\test\js\controller文件夹web.xml在 src\main\webapp\WEB-INF\文件夹js-rest.xml在 src\main\webapp\WEB-INF\spring\文件夹

试过了localhost:8080\schedule\joblocalhost:8080\<projectname>\schedule\joblocalhost:8080\joblocalhost:8080\<project-name>\job
我得到的只是 404 未找到。

我在这里错过了什么吗？

我认为你不应该有 *在 Controller 路径中。试试这个，看看是否有效。

@Controller
@RequestMapping(value="/schedule") // removed the /*
public class ScheduleController {

   @RequestMapping(value="/job", method=RequestMethod.GET)
   @ResponseBody
    public String test(@RequestParam (value = "name", required = false) String name) throws Exception{

    System.out.println("name:" + name);
    return "Yes, I got it, " + name;
   }
}

此外，如果您想要像项目名称这样的捕获组，您最好使用 @Pathvariable像这样的注释。

   @RequestMapping(value="/{projectName}/job", method=RequestMethod.GET)
   @ResponseBody
    public String test(@Pathvariable("projectName") String projectName) throws Exception{
      ...
   }
