I have been stuck on this problem for a very long time. I have looked on resources on the Internet but cannot find where I am going wrong. I have configured Spring MVC to send and receive JSON. When I invoke a RESTful service from the web browser for @ResponseBody the Object that is being returned is returned as JSON. However, when trying to invoke a @RequestBody I am unable to.

Below is the code:

web.xml

<?xml version="1.0" encoding="UTF-8"?> 
     <display-name>WebApp</display-name>

     <context-param>
        <!-- Specifies the list of Spring Configuration files in comma     separated format.-->
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/history-service.xml</param-value>
     </context-param>

     <listener>
        <!-- Loads your Configuration Files-->
        <listener-    class>org.springframework.web.context.ContextLoaderListener</listener-class>
     </listener>

     <servlet>
        <servlet-name>history</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
     </servlet>

     <servlet-mapping>
        <servlet-name>history</servlet-name>
        <url-pattern>/</url-pattern>
     </servlet-mapping>

     <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
     </welcome-file-list>

history-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans>     
    <context:component-scan base-package="com.web"/>

    <mvc:annotation-driven/>

    <context:annotation-config/>

    <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>

    <bean id="jacksonMessageChanger" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
        <property name="supportedMediaTypes" value="application/json"/>
    </bean>

    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <ref bean="jacksonMessageChanger"/>
            </list>
        </property>
    </bean>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!-- <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
        <property name="mediaTypes">
            <map>
                <entry key="json" value="application/json"/>
            </map>
        </property>
    </bean>-->

Controller class

   @Controller
   @RequestMapping("/history/*")
   public class ControllerI {

@RequestMapping(value = "save", method = RequestMethod.POST, headers = {"content-            type=application/json"})
public @ResponseBody UserResponse save(@RequestBody User user) throws Exception {
    UserResponse userResponse = new UserResponse();
    return userResponse;
}

@RequestMapping(value = "delete", method = RequestMethod.GET)
public @ResponseBody UserResponse delete() {
    System.out.println("Delete");
    UserResponse userResponse = new UserResponse();
    userResponse.setSuccess(true);
    return userResponse;
}

When invoking /webapp/history/delete I can receive JSON.

Index.jsp

    <%@page language="java" contentType="text/html"%>
 <html>
 <head>
 </head>
 <body>
 <h2>WebApp</h2>
<form action="/webapp/history/save" method="POST" accept="application/json">
    <input name="userId" value="Hello">
    <input name="location" value="location">
    <input name="emailAddress" value="hello@hello.com">
    <input name="commitMessage" value="I">
    <input type="submit" value="Submit">
</form>
</body>
</html>

However, when invoking the /save I get the following error:

org.springframework.web.servlet.mvc.support.DefaultHandlerE
xceptionResolver handleNoSuchRequestHandlingMethod
WARNING: No matching handler method found for servlet request: path '/history/sa
ve', method 'POST', parameters map['location' -> array<String>['location'], 'use
rId' -> array<String>['Hello'], 'emailAddress' -> array<String>['hello@hello.com'], 'commitMessage' -> array<String>['I']]

I am not sure where I am going wrong. All I want to do is send JSON through JSP to the Spring MVC Controller so the @RequestBody can be turned deserialized into Java from JSON.

I hope you can help.

    chage accept=”application/json” to enctype=”application/json” on your HTML form.

    Spring can not parse you post data for you did not set the current headers.
    When use @RequestBody the default accept enctype is application/json.
    try to one of this:

    1. set post headers=”content-type=application/json” on you html form or js post function.
    2. set you controller to accept headers=”content-type=application/x-www-form-urlencoded”.

    Edit

    The enctype must the same as headers.
    Ok, the code now looks like one of those:

    // the one
@RequestMapping(value = "save", method = RequestMethod.POST)
public @ResponseBody UserResponse save(@RequestBody User user) throws Exception {
    UserResponse userResponse = new UserResponse();
    return userResponse;
}


</form>
<form action="/webapp/history/save" method="POST" enctype="application/x-www-form-urlencoded">
    <input name="userId" value="user">
    <input name="location" value="location">
    <input name="emailAddress" value="hello@hello.com">
    <input name="commitMessage" value="I">
    <input type="submit" value="Submit">
</form>


// the other
@RequestMapping(value = "save", method = RequestMethod.POST, headers = {"content-type=application/x-www-form-urlencoded"})
public @ResponseBody UserResponse save(@RequestBody User user) throws Exception {
    UserResponse userResponse = new UserResponse();
    return userResponse;
}


</form>
<form action="/webapp/history/save" method="POST" enctype="application/json">
    <input name="userId" value="user">
    <input name="location" value="location">
    <input name="emailAddress" value="hello@hello.com">
    <input name="commitMessage" value="I">
    <input type="submit" value="Submit">
</form>

    Try one of those above.

    I get the following error:

    HTTP Error 415: The server refused this request because the request
    entity is in a format not supported by the requested resource for the
    requested method ().
