Spring_mvc接收POST请求报415错误，请高人解决！

[fevermxp]

我用Spring_mvc写了一个接收POST请求的api，但是测试的时候Tomcat返回415错误。数据没有进后台。
POST参数如下：


相关代码如下：
TaxController.java //用于接收参数

package com.gree.tax.controlers;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
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.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import com.gree.tax.model.ReceiveFileInfo;
import com.gree.tax.model.ResultCode;
import com.gree.tax.services.TaxServices;

@Controller
@RequestMapping("/tax")
public class TaxController {

	@RequestMapping(value = "/upload.do", method = RequestMethod.POST)
	public @ResponseBody
	ResultCode upload(@RequestBody final ReceiveFileInfo receiveFileInfo,
			@RequestParam("md5") String md5) {
		//System.out.println(receiveFileInfo.getBody());
		//System.out.println(md5);
		return ResultCode.SUCCESS;
	}
}

ReceiveFileInfo.java //参数对象

package com.gree.tax.model;

public class ReceiveFileInfo {
	private Header header;
	private String body;

	public Header getHeader() {
		return header;
	}

	public void setHeader(Header header) {
		this.header = header;
	}

	public String getBody() {
		return body;
	}

	public void setBody(String body) {
		this.body = body;
	}

}

Header.java

package com.gree.tax.model;

public class Header {
	private String greeCode;
	private String keyId;
	private String updateDate;
	private String supCode;
	private String supPwd;
	private String operationName;

	public String getGreeCode() {
		return greeCode;
	}

	public void setGreeCode(String greeCode) {
		this.greeCode = greeCode;
	}

	public String getKeyId() {
		return keyId;
	}

	public void setKeyId(String keyId) {
		this.keyId = keyId;
	}

	public String getUpdateDate() {
		return updateDate;
	}

	public void setUpdateDate(String updateDate) {
		this.updateDate = updateDate;
	}

	public String getSupCode() {
		return supCode;
	}

	public void setSupCode(String supCode) {
		this.supCode = supCode;
	}

	public String getSupPwd() {
		return supPwd;
	}

	public void setSupPwd(String supPwd) {
		this.supPwd = supPwd;
	}

	public String getOperationName() {
		return operationName;
	}

	public void setOperationName(String operationName) {
		this.operationName = operationName;
	}

}
