SpringMVC集成fastjson遇到的问题

1. SpringMVC 集成fastjson

在SpringMVC中集成fastjson, 集成之后&＃xff0c;注解 &＃64;ResponseBody 返回的对象就能够自动解析成 json数据返回。
fastjson 的效率要高于 jackson、gson

1. 下载 fastjson.jar

2. 配置 springmvc.xml 文件

application/json;charset&＃61;UTF-8


1. 添加注解 &＃64;ResponseBody

&＃64;RequestMapping(value &＃61; "/ajax")public &＃64;ResponseBodyCustomer ajax(Integer id, HttpServletResponse response) {Customer customer &＃61; customerService.queryCustomerById(id);response.setContentType("text/html;charset&＃61;utf-8");return customer;}

返回的数据格式:


{"cust_address": "北京三里桥","cust_createtime": 1460104321000,"cust_id": 16,"cust_industry": "2","cust_level": "22","cust_linkman": "马化腾","cust_mobile": "13888888888","cust_name": "刘强东","cust_phone": "0108888887","cust_source": "6","cust_zipcode": "123456"
}


2. 配置 fastjson 后&＃xff0c;返回字符串时会在外面强制添加双引号

例如:

1. 如果返回的字符串为 哈哈, 最终返回得到的数据是 "哈哈"
2. 返回的字符串中包含双引号&＃xff0c;例如{"name":"ethan"}&＃xff0c;则 fastjson处理后&＃xff0c;最终返回的结果是 "{\"name\":\"ethan\"}"

要想得到原始字符串,解决办法:
添加配置字符串转换器StringHttpMessageConverter
