POST JSON 失败，出现 415 Unsupported media type, Spring 3 mvc（postman json parse error）

我正在尝试向 servlet 发送 POST 请求。请求是通过 jQuery 以这种方式发送的：

var productCategory = new Object();productCategory.idProductCategory = 1;productCategory.description = "Descrizione2";newCategory(productCategory);

newCategory 在哪里

function newCategory(productCategory){  $.postJSON("ajax/newproductcategory", productCategory, function(      idProductCategory)  {    console.debug("Inserted: " + idProductCategory);  });}

而 postJSON 是

$.postJSON = function(url, data, callback) {    return jQuery.ajax({    ''type'': ''POST'',    ''url'': url,    ''contentType'': ''application/json'',    ''data'': JSON.stringify(data),    ''dataType'': ''json'',    ''success'': callback    });};

使用 firebug，我看到 JSON 发送正确：

{"idProductCategory":1,"description":"Descrizione2"}

但我得到 415 Unsupported media type。Spring mvc 控制器具有签名

    @RequestMapping(value = "/ajax/newproductcategory", method = RequestMethod.POST)public @ResponseBodyInteger newProductCategory(HttpServletRequest request,        @RequestBody ProductCategory productCategory)

前几天有效，现在无效。如果需要，我会显示更多代码。

我设法使它工作。告诉我，以防我错了。@JSONSerialize我只使用了一种方法来序列化/反序列化：我删除了关于这个
(和)的所有注释，并在课堂上@JSONDeserialize注册了序列化器和反序列化器。CustomObjectMapper我没有找到解释这种行为的文章，但我以这种方式解决了。希望它有用。

$.ajax访问RESTful Web Service报错:Unsupported Media Type

最近在项目中，前台页面使用jquery ajax访问后台CXF发布的rest服务，结果遇到了错误"Unsupported Media Type"。

发布的服务java代码如下:

import javax.jws.WebService;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;

@WebService
@Produces({ "application/json" })
public class TrackService {
	@POST
	@Path("/trackInBatch/")
	@Consumes("application/json")
	public Response postTrackInfoInBatch(List<TrackPosition> positions) {
		return retrieve(positions,clientGen,trafficMapLayerId,projectParaLayerId,"0");
	}
}

调用服务的javascript代码如下：

$.ajax({
	url : "/myapp/rest/track/trackInBatch/",async:false,type : "POST",dataType:"json",data:[],error:function(XMLHttpRequest,textStatus,errorThrown){
		alert(errorThrown);
	},success: function(data,textStatus){
		outResponse = data;
	}		
});

调用的服务的时候报错：Unsupported Media Type。通过HttpWatch查看原始的request和response报文，发现返回request报文中的contentType是：application/x-www-form-urlencoded。查看jquery.ajax()的api文档，发现contentType的默认值就是：application/x-www-form-urlencoded。

但是后台发布的rest服务，@Consumes("application/json")要求request报文的contentType必须是application/json。

手动设置contentType之后，发现问题解决。

$.ajax({
	url : "/myapp/rest/track/trackInBatch/",contentType:"application/json",textStatus){
		outResponse = data;
	}		
});

415 Spring应用程序中不支持POST请求的MediaType

我有一个非常简单的Spring应用程序（没有Spring Boot）。我已经实现了GET和POST控制器方法。该GET方法效果很好。但是，POST正在抛出415 Unsupported MediaType。复制步骤如下

ServiceController. java

package com.example.myApp.controller;import org.springframework.stereotype.Controller;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;    @Controller    @RequestMapping("/service/example")    public class ServiceController {        @RequestMapping(value="sample", method = RequestMethod.GET)        @ResponseBody    public String getResp() {        return "DONE";    }    @RequestMapping(value="sample2", method = RequestMethod.POST, consumes = "application/json")    @ResponseBody    public String getResponse2(@RequestBody Person person) {        return "id is " + person.getId();    }}class Person {    private int id;    private String name;    public Person(){    }    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }}

AppConfig.java

package com.example.myApp.app.config;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.EnableWebMvc;import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;@Configuration@EnableWebMvc@ComponentScan("com.example.myApp")public class AppConfig extends WebMvcConfigurerAdapter {    @Override    public void addResourceHandlers(ResourceHandlerRegistry registry) {        registry.addResourceHandler("/test/**").addResourceLocations("/test/").setCachePeriod(0);        registry.addResourceHandler("/css/**").addResourceLocations("/css/").setCachePeriod(0);        registry.addResourceHandler("/img/**").addResourceLocations("/img/").setCachePeriod(0);        registry.addResourceHandler("/js/**").addResourceLocations("/js/").setCachePeriod(0);    }}

AppInitializer.java

package com.example.myApp.app.config;import org.springframework.web.WebApplicationInitializer;import org.springframework.web.context.ContextLoaderListener;import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;import org.springframework.web.servlet.DispatcherServlet;import javax.servlet.ServletContext;import javax.servlet.ServletException;import javax.servlet.ServletRegistration;public class AppInitializer implements WebApplicationInitializer {    @Override    public void onStartup(ServletContext servletContext) throws ServletException {        // Create the ''root'' Spring application context        AnnotationConfigWebApplicationContext rootContext =                new AnnotationConfigWebApplicationContext();        rootContext.register(AppConfig.class);        servletContext.addListener(new ContextLoaderListener(rootContext));        // Register and map the dispatcher servlet        ServletRegistration.Dynamic dispatcher =                servletContext.addServlet("dispatcher", new DispatcherServlet(rootContext));        dispatcher.setLoadOnStartup(1);        dispatcher.addMapping("/");    }}

该代码在这里可用：

git clone https://bitbucket.org/SpringDevSeattle/springrestcontroller.git./gradlew clean build tomatrunwar

这将旋转嵌入式tomcat。

现在你可以卷曲以下内容

curl -X GET -H "Content-Type: application/json" "http://localhost:8095/myApp/service/example/sample"

工作良好

但

curl -X POST -H "Content-Type: application/json" ''{    "id":1,    "name":"sai"}'' "http://localhost:8095/myApp/service/example/sample2"

引发415不支持的MediaType

<body>        <h1>HTTP Status 415 - </h1>        <HR size="1" noshade="noshade">        <p>            <b>type</b> Status report        </p>        <p>            <b>message</b>            <u></u>        </p>        <p>            <b>description</b>            <u>The server refused this request because the request entity is in a format not supported by the requested resource for the requested method.</u>        </p>        <HR size="1" noshade="noshade">        <h3>Apache Tomcat/7.0.54</h3>    </body>

我找到了解决方案，因此我想在这里发布，以使他人受益。

首先，我需要在我的类路径中包含杰克逊，我在build.gradle中添加了以下内容：

 compile ''com.fasterxml.jackson.core:jackson-databind:2.7.5''    compile ''com.fasterxml.jackson.core:jackson-annotations:2.7.5''    compile ''com.fasterxml.jackson.core:jackson-core:2.7.5''

接下来，我必须更改AppConfig其扩展范围WebMvcConfigurerAdapter，如下所示：

@Configuration@EnableWebMvc@ComponentScan("com.example.myApp")public class AppConfig extends WebMvcConfigurerAdapter {    @Override    public void addResourceHandlers(ResourceHandlerRegistry registry) {        registry.addResourceHandler("/test/**").addResourceLocations("/test/").setCachePeriod(0);        registry.addResourceHandler("/css/**").addResourceLocations("/css/").setCachePeriod(0);        registry.addResourceHandler("/img/**").addResourceLocations("/img/").setCachePeriod(0);        registry.addResourceHandler("/js/**").addResourceLocations("/js/").setCachePeriod(0);    }    @Override    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {        converters.add(new MappingJackson2HttpMessageConverter());        super.configureMessageConverters(converters);    }}

就这样，一切都很好

415 Unsupported Media Type

今天使用 post 提交表单时显示

"timestamp": "2018-10-25T01:21:54.152+0000",
"status": 415,
"error": "Unsupported Media Type",
"message": "Content type ''application/x-www-form-urlencoded;charset=UTF-8'' not supported",

然后看了下，因为是 post 表单提交的，所以 Content-Type 是 application/x-www-form-urlencoded

查看服务端代码

@RequestMapping(value ="save" , method = RequestMethod.POST)
@ResponseBody
public boolean productSave(@RequestBody Product product){
return productService.saveProduct(product);
}

去掉参数里的 @RequestBody 就可以成功
