ajax+springboot完整例子

1、index.htm

<textarea rows="10" cols="60%" id="cover">ss</textarea>
<input type="button" value="提交" id="btn" />

<td id="resultTd"></td>

<script type="text/javascript" src="jquery.min.js"></script>
<script language='javascript'>
$(document).ready(function() {
    $("#btn").click(function(){
        var cover = $("#cover").val();
        $.post("/cover",{jsonStr: cover},function(result){
            $("#resultTd").html(result.state+","+result.msg);
        });
    });
})
</script>

2、IndexController.java

@Controller
@Slf4j
public class IndexController {
    @RequestMapping(value = "/")
    public String index() {
        return "index";
    }
    @RequestMapping(value = "/cover")
    @ResponseBody
    public ReMsg calc(String jsonStr) {
        log.info("jsonStr={}",jsonStr);
        if (StrUtil.isBlankIfStr(jsonStr)) {
            return new ReMsg(ReMsg.State.FAILURE,"传值为空");
        }
        return new ReMsg(ReMsg.State.SUCCESS,"成功");
    }
}

3、ReMsg.java

@Setter
@Getter
@AllArgsConstructor
@NoArgsConstructor
public class ReMsg {
    public enum State {
        SUCCESS,
        FAILURE
    }
    private State state;
    private String msg;
}

结果：
