I am using Spring 3.2 and try to use an ajax post request to submit an array of json objects. If this is relevant, I escaped all special characters.

I had the same problem. I had to follow these steps to resolve the issue:

1. Make sure you have the following dependencies:

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>${jackson-version}</version> // 2.4.3
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>${jackson-version}</version> // 2.4.3
    </dependency>

2. Create the following filter:

    public class CORSFilter extends OncePerRequestFilter {

        @Override
        protected void doFilterInternal(HttpServletRequest request,
                                        HttpServletResponse response, FilterChain filterChain)
                throws ServletException, IOException {

            String origin = request.getHeader("origin");
            origin = (origin == null || origin.equals("")) ? "null" : origin;
            response.addHeader("Access-Control-Allow-Origin", origin);
            response.addHeader("Access-Control-Allow-Methods", "POST, GET, PUT, UPDATE, DELETE, OPTIONS");
            response.addHeader("Access-Control-Allow-Credentials", "true");
            response.addHeader("Access-Control-Allow-Headers",
                    "Authorization, origin, content-type, accept, x-requested-with");

            filterChain.doFilter(request, response);
        }
    }

3. Apply the above filter for the requests in web.xml

    <filter>
        <filter-name>corsFilter</filter-name>
        <filter-class>com.your.package.CORSFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>corsFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

I hope this is useful to somebody.

Answer 2

I had the same problem, I just brought up the below line of code in the spring-servlet.xml, it was at the almost end of this xml file. It worked. <mvc:annotation-driven />

Answer 3

I had consume="application/json" in my request mapping configuration which expects a json input. When I sent a request which is not a JSON input Spring complained about the 415 Unsupported Media Type. So removing the consume="application/json" worked for me. So look into the request input and the accept media type in your Spring controller method signature. A mismatch would throw the 415 error. This will be most likely the reason for the issue.

Answer 4

You may try with HttpServletRequest. it does not have any problem

  @RequestMapping(value = "/save-profile", method = RequestMethod.POST,consumes="application/json",headers = "content-type=application/x-www-form-urlencoded")
    public @ResponseBody String saveProfileJson(HttpServletRequest request){
       System.out.println(request.getParameter("profileCheckedValues"));
        return "success";
    }

Answer 5

try changing json to application/json for datatype. And what does your json look like is it valid ? I have never seen json converted to a String[] before, so this coul dalso be the problem.

Answer 6

1) Add the following dependencies

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>${jackson-version}</version> // 2.4.3
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>${jackson-version}</version> // 2.4.3
</dependency>

2) If you are using @RequestBody annotation in controller method make sure you have added following in xml file

<mvc:annotation-driven />

This should resolve the 415 status code issue.
