上图是查询列表的接口，get方式
上图是用户注册的接口，同样是get，post方式也很简单
开发工具：intellij idea 2016.3.5
orm框架：mybatis
数据库：mysql
服务器：tomcat7.0
公司使用的的orm框架是hibernate，使用起来感觉比mybatis好用多了，毕竟经过了公司这么多项目的考验，总比自己用mybatis写的项目可靠，但以下分享的还是mybatis的代码
注册接口方法：http://192.168.1.116:8080/register?username=111&password=222

@requestmapping(value = "register", method = requestmethod.get)
@responsebody
public map<string, object> register(@requestparam("username") string username, @requestparam("password") string password) {
out.println("welcome to register,username=" + username + ";password=" + password);
map<string, object> map = new hashmap<>();
resultbean result = onregister(username, password);
out.println("result==>" + result);
map.put("code", result.getcode());
map.put("reason", result.getreason());
map.put("success", result.issuccess());
return map;
}

具体的注册方法，获取session基本和hibernate差不多

这个mapper需要在配置文件中指定

public interface loginmapper {
public loginbean finduserbyname(map<string,object> map) throws exception;
public void adduser(loginbean bean) throws exception;
}

这是对应的loginmapper.xml
