java服务器端控制层代码（特别方便）

1）java服务器端的封装：BaseResult类的封装，特别好用；
2）SpringMVC注解的使用，每个注解的含义；
3）判断提交的表达数据是否为空；
4）调用service层的代码；
5）把json对象转化成字符串并返回。

public class BaseResult {protected boolean success = false;protected String errorCode;protected String errorMsg;protected Map<?, ?> map;protected String msg;public Map<?, ?> getMap() {return map;}public void setMap(Map<?, ?> map) {this.map = map;}public boolean isSuccess() {return success;}public void setSuccess(boolean success) {this.success = success;}public String getErrorCode() {return errorCode;}public void setErrorCode(String errorCode) {this.errorCode = errorCode; }public String getErrorMsg() {return errorMsg;}public void setErrorMsg(String errorMsg) {this.errorMsg = errorMsg;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}}

手势识别模块，服务器端代码(不需要使用json包进行转化，直接返回对象或者集合即可)
