Solution to report HTTP Status 415 when processing json with @requestbody annotations in SPRINGMVC

Spring's @requestbody is very bull x, and you can convert the submitted JSON directly to the Pojo object.

Just today there is such a demand, use, the results have been reported 415, very headache.

HTTP 415 Error – Unsupported media types (Unsupported media type)

That's what my Angularjs wrote.

$http ({method: "POST",    Url:url;    Headers: {' content-type ': ' Application/json;charset=utf-8 '},    data:scope. $modelValue}). Success (function (data, Status) {    //Success handle Code  }). Error (Function (data, status) {    //Error handle code});

URL and scope. $modelValue is the code in the project, where it occupies a pit, scope. $modelValue is a JS object that is converted to a JSON string by Angularjs.

Repeatedly look at the Angularjs document, and grab packet analysis, confirm JS no problem.

A search on the internet seems to be the problem of spring, some netizens said need to increase <mvc:annotation-driven/> in the *-servlet.xml, a look at my project did not add, immediately add.

Of course, you also need to add MVC's XML namespace, otherwise the configuration cannot be resolved.

Xmlns:mvc= "Http://www.springframework.org/schema/mvc" xsi:schemalocation= "Http://www.springframework.org/schema /mvchttp://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd "

<mvc:annotation-driven/> Automatically registers defaultannotationhandlermapping and annotationmethodhandleradapter two beans

The Annotationmethodhandleradapter will initialize 7 converters, which can be called by calling Annotationmethodhandleradapter's Getmessageconverts () method to get a collection of converters list

Bytearrayhttpmessageconverter Stringhttpmessageconverter Resourcehttpmessageconverter SourceHttpMessageConverter Xmlawareformhttpmessageconverter Jaxb2rootelementhttpmessageconverter Mappingjacksonhttpmessageconverter

Parsing of JSON is done through the Mappingjacksonhttpmessageconverter converter.

Add <mvc:annotation-driven/> Not yet, you need to find the Jackson bag in the CLASSPATH environment, with maven configured as follows

<dependency>          <groupId>org.codehaus.jackson</groupId>          <artifactId> jackson-mapper-asl</artifactid>          <version>1.9.8</version>          <type>jar</type >          <scope>compile</scope>   </dependency>  

Now that the problem is resolved, enclose the spring code

@RequestMapping (value = "/testjson", method = requestmethod.post, consumes = "Application/json") @ResponseBodypublic void Testjson (@RequestBody jsoninfo jsoninfo,    httpservletrequest request, httpservletresponse response) {    // Handle Jsoninfo Object Instance}

Help from the following, thank the author:)
