415 Spring应用程序中不支持POST请求的MediaType [英] 415 Unsupported MediaType for POST request in spring application
问题描述
我有一个非常简单的Spring
应用程序(没有弹簧启动).我已经实现了GET和POST控制器方法. GET
方法可以正常工作.但是POST
抛出415 Unsupported MediaType
.复制步骤如下所示:
I have a very simple Spring
Application (NOT spring boot). I have implemented a GET and POST controller methods. the GET
method works fine. But the POST
is throwing 415 Unsupported MediaType
. Steps to reproduce are available below
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("/");
}
}
代码可在此处获得:
git clone https://bitbucket.org/SpringDevSeattle/springrestcontroller.git
./gradlew clean build tomatrunwar
这将旋转嵌入式tomcat.
This spins up embedded tomcat.
现在您可以卷曲以下内容
Now you can curl the following
curl -X GET -H "Content-Type: application/json" "http://localhost:8095/myApp/service/example/sample"
工作正常
但是
curl -X POST -H "Content-Type: application/json" '{
"id":1,
"name":"sai"
}' "http://localhost:8095/myApp/service/example/sample2"
抛出415不支持的MediaType

推荐答案
我找到了解决方案,我想在这里发布,以使其他人受益.
I found the solution and I want to post here so it benefits others.
首先,我需要在我的类路径中包含杰克逊,我将其添加到build.gradle中,如下所示:
Firstly I need to include jackson in my classpath, which I added in build.gradle as follows:
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,我必须更改对WebMvcConfigurerAdapter
进行扩展的AppConfig
,如下所示:
Next, I have to change my AppConfig
which extends WebMvcConfigurerAdapter
as follows:
@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);
}
}
仅此而已,一切都很好
