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
Spring
GET
POST
415 Unsupported MediaType
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:
AppConfig
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); } @Override public void configureMessageConverters(List<HttpMessageConverter<?>> converters) { converters.add(new MappingJackson2HttpMessageConverter()); super.configureMessageConverters(converters); } }
就这样,一切都很好
