I've tried for awhile, how come this thing does not get a response? It always couldn't find the url mapping/404 not found. I am trying to send json request to localhost/test and wish I could get any response, but invain.
This is my web.xml file
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
This is the dispather-servlet.xml file
<?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:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring- beans-3.0.xsd">
<bean name="test" class="com.my.controller.TestController"></bean>
</beans>
This is the TestController.java:
@Controller
@RequestMapping("/")
public class TestController {
@RequestMapping(value = {"/test"}, headers = "Accept=application/json")
public String getBid(HttpServletRequest request, HttpServletResponse response) throws Exception {
System.out.println("test...");
return "is itworking?!";
}
}
Probably, You should return from getBid(...) logic name of view ("test") - don't return sample string like this -> "is itworking?!". Another solution is use @ResponseBody to JSON - link .
除非您在配置中包含<mvc:annotation-driven/>
,否则Spring将不会理解TestController
是一个控制器,否则,您需要@ResponseBody
