请求示例：将传输的对象JSON.stringify()

JSON.stringify() 表示从一个对象中解析出字符串

    $.ajax({       url: "http://localhost:8201/search",       type: "post",       contentType: "application/json;charset=UTF-8",       dataType: "json",       data: JSON.stringify({key: keyword})     }).success(function (res) {       console.log(res)     })

接收样例：

	@RequestMapping(value = "/search",method = RequestMethod.POST) 	@ResponseBody 	public List<Product> search(@RequestBody SearchRequestDTO searchRequestDTO){ 		List<Product> products =  searchService.search(searchRequestDTO); 		logger.info("商品数量{},商品信息{}",products.size(),products.toString()); 		return products; 	}

其中DTO类：

package com.goods.search.api.DTO;  import java.io.Serializable;  public class SearchRequestDTO implements Serializable {  	private String key;  	/** 	 * 获取key 	 * 	 * @return key 	 */ 	public String getKey() { 		return key; 	}  	/** 	 * 设置key 	 * 	 * @param key key 	 */ 	public void setKey(String key) { 		this.key = key; 	}  	public SearchRequestDTO() { 	}  	public SearchRequestDTO(String key) { 		this.key = key; 	} }
