我认为这是响应Spring尝试在POST方法被处理后找到一个View.

如何阻止Spring控制器这样做？

这是我的Spring Controller：

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
 
import java.util.ArrayList;
import java.util.List;
 
@Controller
@RequestMapping("/person")
public class DataController {
 
  private List<Person> people = new ArrayList<Person>();
 
  @RequestMapping(value="put",method = RequestMethod.POST)
  public void addPerson(@R_404_13@("person") Person person){
    System.out.println(">>>>>>> person: " + person);
    System.out.println(">>>>>>>>> " + person.getFirstName());
    people.add(person);
  }
}

这是我的应用程序上下文xml文件：

<?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/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
 
    <context:component-scan base-package="uk.co.jeeni" />
 
    <mvc:annotation-driven />
 
</beans>

这是我的web.xml文件：

<?xml version="1.0" encoding="ISO-8859-1" ?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
                http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
         version="2.4">
 
    <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:applicationContext-web.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
 
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/data/*</url-pattern>
    </servlet-mapping>
</web-app>

这是我的HTML文件中的JQuery调用：

function attachSendDataEvent(){
    $("#sendData").click(function(){
 
        var data = "firstName=" + $("#firstName").val() + "&" +
                "lastName=" + $("#lastName").val() + "&" +
                "address=" + $("#address").val() + "&" +
                "postcode=" + $("#postcode").val();
 
        $.post("data/person/put",data,dataSentOK
        );
    });
 
    return false;
}

dataSentOK函数只执行一个警报(“DONE”).

所以当JQuery方法调用的URL是：

http://localhost:8080/jquery/data/person/put

而在服务器端,System.out.println(…)方法打印出预期的数据.

但是在Firebug中,服务器发回404.

所以我开始使用Spring进行日志记录,得到：

[01] DispatcherServlet [DEBUG] DispatcherServlet with name 'dispatcherServlet' processing POST request for [/jquery/data/person/put]
[02] AbstractHandlerMethodMapping [DEBUG] Looking up handler method for path /person/put
[03] AbstractHandlerMethodMapping [DEBUG] Returning handler method [public void uk.co.jeeni.DataController.addPerson(uk.co.jeeni.Person)]

[13] FrameworkServlet [DEBUG] Successfully completed request
[14] FrameworkServlet [DEBUG] Successfully completed request

响应URL POST请求(/ jquery / data / person / put),找到并调用正确的方法(第1行到第7行),但是Spring将转发到第8行的InternalResourceView,该URL将URL更改为/ jquery / data / person / person / put,这是无法找到的.

如何阻止Spring试图找到一个视图.所有我想要做的都是干净地返回并完成.

谢谢你的帮助.
