【问题描述】：
我有一个非常简单的Spring 应用程序（不是弹簧启动）。我已经实现了 GET 和 POST 控制器方法。 GET 方法工作正常。但是POST 正在抛出415 Unsupported MediaType。下面提供了重现的步骤
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("/");
}
}
代码在这里：
git clone https://bitbucket.org/SpringDevSeattle/springrestcontroller.git
./gradlew clean build tomatrunwar
这会启动嵌入式 tomcat。
现在你可以卷曲以下内容了
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 unsupported MediaType
