415 (Unsupported Media Type)-CFANZ编程社区

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>

希望对你有所帮助
