SpringMVC中@RequestBody 返回对象为String类型时中文字符乱码

1.出现乱码

@RequestMapping(value="/businessedit.do", method = RequestMethod.POST)

@ResponseBody

public String businessedit(Integer sourceid){

String tip = "该业务已经存在";

return tip;

}

2.返回正确的编码格式

@RequestMapping(value="/businessedit.do", method = RequestMethod.POST)

@ResponseBody

public List businessedit(Integer sourceid){

String tip = "该业务已经存在";

List tips = new ArrayList();

tips.add(tip);

return tips;

}

其实就是将String封装为list集合，那么前端ajax返回的data就不会出现乱码。
