415 (Unsupported Media Type)

接口:

package com.wdg.index.controller;

import java.util.Map;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/indexcontroller")
public class IndexController {
	
	
	@RequestMapping(value="/pageload",produces = "application/json; charset=UTF-8")
	public @ResponseBody String pageload(Map<String, String> reqMap){
		System.out.println("你好");
		return null;
		
	}

}

调用:

function execFunc(methodname, param, callback) {
	var strs = [];
	if (methodname.indexOf('/') > 0) {
		strs = methodname.split('/');
	} else {
		strs = methodname.split('.');
	}
	var actionname = strs[0];
	var funcname = strs[1];
	var serviceUrl = getProjectURL();
	var json = null;
	params = JSON.stringify(param);// 这个是将参数转换为json
	$.ajax({
		url : serviceUrl + actionname + '\/' + funcname,
		contentType : "application/json;charset=UTF-8",
		type : 'post',
		data : params,
		success : function(data) {
			callback(data);
		},
		error : function(error) {
			json = null;
			callback(json);
			console.log('接口不通' + methodname + error);
		}
	});

}

	execFunc("indexcontroller.pageload",{},function(data){
		console.log(data);
	})

错误:

    415 (Unsupported Media Type)

解决办法:

pom.xml中新增jar:

		<!-- Sring前台传入的json和参数绑定 -->
		<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-databind</artifactId>
			<version>2.9.1</version>
		</dependency>
