春天REST风格的AJAX得到错误 [英] Spring RESTful ajax gets error
本文介绍了春天REST风格的AJAX得到错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
当我把我的服务地址的http：//本地主机：8080 / mailservice /邮件/名称到Web浏览器的地址栏中，然后我收到响应以JSON是这样的：
When I put my service address http://localhost:8080/mailservice/mail/name into web browser address bar then I receive response in json like this :
["name"]
但是当我创建一个简单的HTML页面这样的波纹管：
but when i create a simple html page like this bellow:
<html>
<head>
<script src="http://code.jquery.com/jquery-2.1.0.min.js"></script>
<script>
$( document ).ready(function() {
doMagic();
});
function doMagic()
{
$.ajax({
type: 'GET',
url: 'http://localhost:8080/mailservice/mail/name',
contentType:"application/json",
success: function () {
console.log("ok");
},
error: function (request, status, error) {
console.log(status);
}
});
}
</script>
</head>
<body>
<div id="out">
</div>
</body>
</html>
我的ajax总是命中误差函数，如果我使用POST（阿贾克斯code与HTML，而不是$ P $这里psent不同的例子），也无所谓或GET。
my ajax always hits error function, it doesn't matter if I'm using POST (different example of ajax code with html, not present here) or GET.
我的控制器看起来就像是：
My Controller looks like that:
@Controller
@RequestMapping("/mail")
public class MailController {
@Autowired
MailService mailService;
@RequestMapping(value = "/{name}",
method = RequestMethod.GET,
produces={"application/json"})
public @ResponseBody
List<String> getMovie(@PathVariable String name) {
List<String> lista = Arrays.asList(name);
return lista;
}
@RequestMapping(value = "/send",
method = RequestMethod.POST,
produces={"application/json","application/xml"})
@ResponseBody
public String getDefaultMovie(Message message) {
mailService.sendEmail(message);
return "OK!";
}
}
这是萤火虫信息：
GET http://localhost:8080/mailservice/mail/name 200 OK 9ms

解决方案（部分）
我不得不改变HTML文件和web.xml和调度 - servlet.xml中
I had to change html file and web.xml and dispatcher-servlet.xml
$(function() {
var url = 'http://localhost:8080/email/mail/send.jsonp?callback=jsonCallback';
$.ajax({
url: url,
type: "GET",
async: false,
jsonpCallback: 'jsonCallback',
contentType: "application/json",
dataType: 'jsonp',
error: function(a, b, c) {
console.log(JSON.stringify(a)+","+b+","+c);
},
success: function( response ) {
console.log( response );
}
});
});
调度 - servlet.xml中
dispatcher-servlet.xml
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="favorPathExtension" value="true"/>
<property name="mediaTypes">
<map>
<entry key="json" value="application/json"/>
<entry key="jsonp" value="application/javascript"/>
</map>
</property>
<property name="defaultViews">
<list>
<bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView"/>
<bean class="org.szymon.email.classes.MyMapperClass"/>
</list>
</property>
</bean>
web.xml中：
web.xml:
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.json</url-pattern>
<url-pattern>*.jsonp</url-pattern>
<url-pattern>/*</url-pattern>
</servlet-mapping>
MyMapperClass.java
MyMapperClass.java
package org.szymon.email.classes;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.view.json.MappingJacksonJsonView;
public class MyMapperClass extends MappingJacksonJsonView {
/**
* Default content type. Overridable as bean property.
*/
public static final String DEFAULT_CONTENT_TYPE = "application/javascript";
@Override
public String getContentType() {
return DEFAULT_CONTENT_TYPE;
}
/**
* Prepares the view given the specified model, merging it with static
* attributes and a RequestContext attribute, if necessary.
* Delegates to renderMergedOutputModel for the actual rendering.
* @see #renderMergedOutputModel
*/
@Override
public void render(Map<String, ?> model, HttpServletRequest request, HttpServletResponse response) throws Exception {
if("GET".equals(request.getMethod().toUpperCase())) {
@SuppressWarnings("unchecked")
Map<String, String[]> params = request.getParameterMap();
if(params.containsKey("callback")) {
response.getOutputStream().write(new String(params.get("callback")[0] + "(").getBytes());
super.render(model, request, response);
response.getOutputStream().write(new String(");").getBytes());
response.setContentType("application/javascript");
}
else {
super.render(model, request, response);
}
}
else {
super.render(model, request, response);
}
}
}
