上圖是查詢列表的接口，get方式
上圖是用戶注冊的接口，同樣是get，post方式也很簡單
開發工具：intellij idea 2016.3.5
orm框架：mybatis
數據庫：mysql
服務器：tomcat7.0
公司使用的的orm框架是hibernate，使用起來感覺比mybatis好用多了，畢竟經過了公司這么多項目的考驗，總比自己用mybatis寫的項目可靠，但以下分享的還是mybatis的代碼
注冊接口方法：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; } |
具體的注冊方法，獲取session基本和hibernate差不多

這個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;} |
這是對應的loginmapper.xml
