ssh框架里面的action类

1、action类
public String login(){
//adminname和adpassword为空,则返回登录界面,否则验证登录
if(null==adminname&&null==adpassword){
return "login";
}else{
**** Boolean u=AdminService.login(adminname,adpassword);****
if(u){
return "ok";
}else{
return "error";
}
}

    打*****号那行报错:Cannot make a static reference to the non-static method login(String, String) from the type AdminService

    2、AdminService类

public interface AdminService {
public boolean login(String adminName, String adPassword );
}

4个回答

非static的boolean login(String adminName, String adPassword );不能直接通过类名访问,需要向action注入一个AdminService实例,通过实例访问

非static方法不能直接类名.方法名调用

@Autowired
private AdminService adminService ;通过这种方式将service类注入进来,再用adminService.login(adminname,adpassword)调用试试。

沒有引入AdminService:可以使用@Resource注解引入AdminService

ssh框架中Action类的类名必须与Action为结尾吗

ssh框架中Action类的类名必须与Action为结尾吗?写了一个注册登录的action类,如果类名是与Action为结尾,页面可以正常访问![图片说明](https://img-ask.csdn.net/upload/201912/16/1576461181_857906.png) 如果类名是不是Action为结尾,页面可以不能访问 ![图片说明](https://img-ask.csdn.net/upload/201912/16/1576461315_963852.png) 会出现这样找不到类的错误,![图片说明](https://img-ask.csdn.net/upload/201912/16/1576461414_430503.png) 这个是什么问题呢?struts2注解扫描是什么原理

SSH框架中@Service 调用问题,急求大神解答!

我手头有个ssh项目框架,通过jsp页面操作,到Action中依次调用Service、Dao等方法进行操作。我现在需要在其他类中调用该Action中的Service的方法。先看图:这是某个Action中有个sdkDeployService,使用了@Resource注入。下面是Action内容: ![这个是Action内容](https://img-ask.csdn.net/upload/201603/29/1459236674_270359.png) 这个是Service: ![图片说明](https://img-ask.csdn.net/upload/201603/29/1459236743_529741.png) 这个是ServiceImpl: ![图片说明](https://img-ask.csdn.net/upload/201603/29/1459236784_373609.png) 我在其他地方这样写的: @Autowired private SdkDeployService sdkDeployService; sdkDeployService.deploy(); 结果显示:在sdkDeployService.deploy() 这里java.lang.NullPointerException.报空指针。求大神告诉,ssh里如何获得并调用service里的方法。急求,万分感谢!!

SSH框架里这些包分别都代表什么?各自的作用是什么?

在SSH框架中Action接受不到jquery_Ajax的data数据

我的jquery代码是这样的 ``` <script type="text/javascript"> $(document).ready( function(){ $("#btnSearch").click(function(){ var id=$("#sid").val(); $.ajax({ type:"post", url:"${pageContext.request.contextPath }/staffInfo_QuerySInfo.action", contentType:"application/json;charset=UTF-8", async:false, data:{sid:id}, dataType:"json", success:function(json){ console.log(json); var i, x=""; x = json.dataMap.staffInfo.SId; document.getElementById("content").innerHTML = x; }, error:function(){ alert("error"); } }); } ); } ); </script> ``` 表单是这样的 ``` <form class="navbar-form navbar-left" role="search" id="SearchById" > <div class="form-group"> <div class="input-group"> <input id="sid" name="sid" type="text" class="form-control" placeholder="输入编号查询"/> <span class="input-group-btn"> <button id="btnSearch" class="btn btn-default" > <span class="glyphicon glyphicon-search"></span> </button> </span> </div> </div> </form> ``` action的代码如下: ``` package sshpack.action; import java.util.HashMap; import java.util.Map; import org.apache.struts2.ServletActionContext; import com.opensymphony.xwork2.ActionSupport; import sshpack.entity.StaffInfo; import sshpack.service.StaffInfoService; public class StaffInfoAction extends ActionSupport { private StaffInfoService staffInfoService; public void setStaffInfoService(StaffInfoService staffInfoService) { this.staffInfoService = staffInfoService; } // 根据编号查询 private Integer sid; public Integer getSid() { return sid; } public void setSid(Integer sid) { this.sid = sid; } private Map<String, Object> dataMap; public Map<String, Object> getDataMap() { return dataMap; } public void setDataMap(Map<String, Object> dataMap) { this.dataMap = dataMap; } public String QuerySInfo() { String Sid = ServletActionContext.getRequest().getParameter("sid"); if (Sid != null) { sid = Integer.valueOf(Sid); } StaffInfo staffInfo = staffInfoService.QueryStaffInfoById(sid); if (staffInfo != null) { dataMap = new HashMap<String, Object>(); dataMap.put("staffInfo", staffInfo); dataMap.put("success", true); return "queryResult"; } else { return "error"; } } ``` Struts为: ``` <package name="json_data" namespace="/" extends="json-default"> <action name="staffInfo_*" class="staffInfoAction" method="{1}"> <result name="queryResult" type="json"> <param name="root">dataMap</param> </result> </action> </package> ``` ![图片说明](https://img-ask.csdn.net/upload/201905/06/1557141786_308791.png) 我猜是不是这里这句话ServletActionContext.getRequest().getParameter("String")有问题啊,不用这个又要怎么才能接收数据啊 就像这样后台的action得不到数据,sid始终是空的,该怎么解决啊,找了好久都没找到解决办法快崩溃了..............
